Caching and ratelimiting made simple. Feedback Welcomed!

Hi, I recently released v0.3.0 of my new package simple-data-loader on npm. It is a simple function wrapper that caches the results in memory as a promise.Its api is heavily inspired from facebook/dataloader but supports very different features.simple-data-loader supports wrapping functions with varying number of arguments, and arguments that are not necessarily primitive values.It is made to be flexible and easy to use. I use it to improve performance and reduce load on external resources (like calls to my database for non realtime sensitive information).Please read the README, and let me know if this is something you would like to use in your projects.All feedback is welcome.link to npm: simple-data-loaderThanks!

Need help running a file.

Hey, I am doing a project for a job interview, and they want me to make a small program using Sibilant, which I never used before. I followed the instructions they gave me, but can't get passed this point ";; Install Sibilant by running: ;; npm install -g sibilant ;; Then, copy this file to a local directory and run it to see an explanation of the project: ;; sibilant -x -f project.sibilant "I installed NPM, node.js and sibilant, and copied the GitHub file to my local directory, but when I try to run the file, nothing happens. I know to replace the -x with the directory, and -f with filename. I am not asking for help on the project, just getting the file to run.​Thank you in advance.

Inserting a hashed password into MongoDB with bcrypt does not work, but plain text password inserts fine

Sorry if this is a really novice question. I'm currently learning Vue with a Node backend and am creating a Sign Up form.My form posts the sign up data to the backend using the fetch API. I catch the POST request in my server.js file and create a newUsermodel. When populating the password of the model, I run it through an encryption method using bcrypt:let newUser = new userModel({ username: username, email: email, password: hashPassword(password) }); hashPassword function:function hashPassword(password) { bcrypt.genSalt(saltRounds, (err, salt) => { if(err) { return console.log(err); } bcrypt.hash(password, salt, (err, hash) => { if(err) { return console.log(err); } return hash; }) }); save new user:newUser.save((err, user) => { if(err) { return res.send({ success: false, message: 'Server error: ' + err }); } return res.send({ success: true, message: username + ' successfully added.' }); }); and for some reason, the password will not save into my MongoDB instance hashed, but saves fine as plain text.Can anyone help please? Or point out a stupid mistake I've made somewhere.If you need any more info or code samples, please let me know.Thanks for your help. :)

Hosting a web server on my companies internal network with a VM (Red Hat Linux)

I'm trying to host a web server on a VM running Red hat Linux in a Network Attached Storage unit on my company's network using NodeJS/Express. I've hosted a server with Express before on my own personal computer on my home network, but I can't seem to figure out how to do it in this setting.In the interest of privacy, I'm not going to actually write out the IPs, as I don't know how those could be used adversely...so I'd rather be safe.I'm listening to port 3000 in Node on the VM, and the NAS is located at "IP1"(10.xx.xx.xx) on our network. As of now, all the server does is return some JSON when the "/" route is requested.After running ifconfig, I see an "inet" IP and a "broadcast" IP, and I've tried navigating to those via port 3000 in my browser and I get nothing.I access the VM for remote access via http://IP1:8080. IP1:3000 doesn't work in my browser either.Do I need to forward the ports within the VM somehow? So that port 80 points at 3000, or something similar? Please feel free to ask questions, as this is something I'm new to (Red Hat Linux and hosting a server on an internal intranet via VM).To clarify, this server is NOT meant to reach out to the Internet, only within my company's network. We have lots of web services running this same way, so I know it can be done, I've just never done it before so I'm a bit lost.EDIT: Spelling

Learning Node without JS experience

Hi, I'm looking for the best resource (online) that would help me jump into Node.js without any JS experience. I bought a udemy course on Node JS, all was going well but I'm starting to slow down.​An example is:var duplicateNotes = notes.filter((note) => {return note.title === title;});​I have the fundamental grasp that filter takes a callback but the syntax is really throwing me off. I can simplify the line some by moving the function and calling it but I'm still struggling with the idea.​I don't need the above explained, it's just an example of what I need from a JS tutorial.​

Framework help

Hello guys​I will be building a game server, and I need some help in choosing a framework.I would like to choose a framework that does most of the decisions for me as in architecture and relations. Since I am still learning node, I would like to use this opportunity to learn from a fw that has best practises inside.​For the game part, I will need web frontend for statistics, bunch of tables and some actions as well. Players will be able to enter the dashboard to see detailed statistics for themself, so It would be cool if the framework has support for different user groups ect.. I will use angular6 to build it.Database should be mongo, as it is the one I am familiar with and I have been using it for some time now.Mobile app for the game will be needing socket connection to the game server. Although, there is no multiplayer options, It would be good if I could have chat groups for players to enter and chat. Also, user session management and (login logout) would be great.​I already looked into several frameworks (sails, loopback, actionhero, nestjs, ect...), but I know you have much more experience in them so you can help me make the right choice.​I am familiar with writing game backend code, but not so much with dashboard features. This, with socket user session management would be the main part where I would expect help from the framework.I come from strongly typed environment, so typescript or modern js features are a plus if used. Anything that goes in that direction.Scaling of course is important.​Is there one solution for this, or will I need to do game server and dashboard separately?​Help me please :)​My colleague brought to my mind that our priority is game backend. We can always hook up dashboard up with loopback+angular.

Complete beginner wondering how to work a GroupMe bot example in node.js

Hi, I’ve been working on a GroupMe bot for chats that are specified for different subjects for my classes to have fun and assist my classmates but I’m completely new to this and have been following this template and it works well for commands that take input from a user in the chat and provide output like an image. I’ve already deployed it to Heroku and it works in the chats for responding to commands with just text or links.I’m wondering how to connect to things like Google Calendar, which is probably through their API, but I’m wondering how I’d go along as to doing that for taking a command input with details, for example: /addevent Test Friday which would add that event to a google calendar on the upcoming Friday, and later have that same bot give a reminder the day before the event begins.Any pointers for learning how to connect with the API or even if there’s npm packages that would work for the GroupMe bot that’d be very helpful.Basically my question is, how can I use external API’s when someone tries to use a command in a GroupMe chat so that they’d get a response based on that API’s information?Maybe tutorials or anything of the sort that would help in regards to what I’m trying to do?

Temporary Session Storage using Node.js?

I have a bot that I have coded in node.js and users interact with this bot. You can talk with it and use commands but everything is pretty come and go. There is no storage of persistent data (except for a MySQL database to keep track of certain things like how much gold a person has, which they obtain by interacting with the bot)​I was working on creating some games with the bot that users can gamble the gold with. And the game I coded was a blackjack game. (Simple 21 against the bot)​The user is dealt two cards to start and can either hit or stay and the values are added up. The hard part of this though, is that only one person can seem to play at a time because of conflicting function calls. So I was wondering if there was a way using node.js to have temporary storage of persistent asynchronous data.So I could code something like:function playBlackjack(userid, betamount){ session_start(); var unique_id = session['id']; { ... } //all the code for the various things like hitMe(), stay(), start(), endGame() etc... giveReward(session['id']); //for if they win/lose it'll get removed/added to their mysql user session_end(); //this cleanly ends the players session and if they were to run the blackjack command again it would start a fresh session, giving their userid a new session variable } So that way the user can walk away from the bot, come back tomorrow and since the session never ended they can pick up where they left off and continue playing as long as their session hasnt ended cleanly and other users data for their unique sessions are tracked individually.I generally dont want to use a JSON file to do this because I dont want to clog the server up with JSON files (sure I could have them set to auto delete after X amount of time, but if there is a more elegant solution I would love to explore that)​Next, I want to try to code a DND mini game where the bot generates random scenarios (this parts already done) but I need persistent sessions so that when the bot prompts the user to roll a die and awaits their response, they enter !roll d20 and the value thats retrieved from the roll, can then be used in the bot for the progression of the story telling. I wonder what is the cleanest way to handle this also. I dont think MySQL would work here, nor would a JSON file unless i create a JSON file that has username, date/time, story (other data like gold, stats etc) to keep the story telling persistent..​Any ideas? If the JSON route is the best, I assume I would have to create files like:DND_userid.jsonBLACKJACK_userid.json​which would have multiple arrays with session_idsI reckon it would look something like this{ "user_id" : "mrsodasexy", "mode": "DND", "sessions": [ { "id" : "845skjjd93jf94f", "data": [ { "date_start" : "08/27/2018 15:11:11", "date_end" : "08/27/2018 16:30:32", "story" : " ... ", //as HTML string "last_sentence" : "you rested in the inn", "stats" : [ ... ], "inventory" : [ ... ] } ] }, { "id" : "167sjd93j9woiwiw", "data": [ { "date_start" : "08/28/2018 16:14:16", "date_end" : "", "story" : " ... ", //as HTML string "last_sentence" : "and you found 20 pieces of gold", "stats" : [ ... ], "inventory" : [ ... ] } ] } ] } And I would just look for each session where date_end is empty and continue from that session?Is that the best way to do this?​

We can discuss tech news, do code reviews for our open source projects, help each other with finding solutions for tech problems, etc.I try to have one voice chat per day. I work in small teams and such conversations help me be informed about tech news and trends, learn new patterns and so on.I'm able to have the conversation within this time range: 4:00-9:00, 12:00-18:00 UTC, any day of week.If you are interested in discussing above-described techs and that time range is suitable for you, contact me via Discord max7z#4494 or Email max7z@protonmail.comThank you!

Best practices for file structure in a Node / Express app using Gulpjs

I've just started messing with Gulp and I really like it's potential. But many of the tutorials I watch depart from the Node / Express file structure that I'm used to.Is it the practice with a Node app using Gulp to simply put an entire project including server files into the production (dist) directory? Minifying everything?

Formatting buffer from console in node / electron app

Hi all, I am working on an app that takes results from a terminal command, like “cd desktop\n ls\n”, and displays it in the UI window. I’ve been able to convert the buffer with .toString(‘utf8’).split(RegEx stuff) etc, and I can get the data formatted, kinda, but what I’m hoping to do is just clone what the output would look like as if you were actually looking at the console. Is there a module or easier way to do this out of the box somewhere? Any suggestions appreciated.Edit: a word

Packing files with the 'targz' package and ignoring .txt files

So I am currently trying to pack all the contents of a folder, but now I want it to ignore all files with a certain extension. The code I have looks like this:targz.compress({ src: "./" + this.sourcePath + "/", dest: "./" + this.targetPath + "/" + "result.tar.gz", tar: { entries: this.fileArray, ignore: function(name) { return path.extname(name) === '.txt' } }, gz: { level: 6, memLevel: 6, } }, function(err){ if(err) { console.log(err); reject(err); } else { resolve(); } }); As I just started with node, I have no idea how I can write this ignore filter into the code in a way that it works: ignore: function(name) { return path.extname(name) === '.txt' } It is supposed to ignore all files with the extension '.txt'.If this is the wrong place to ask please tell me where else I can ask for help :)

Node.js TypeScript Boilerplate Without ts-node

I made something for my own projects that I thought might be useful to anyone trying to set up TypeScript for a Node.js project, who doesn't want to use ts-node to run the tests. I understand that using ts-node is subjective, some people might not share my desire to remove it from my build tools. Personally, I found it hard to get consistent code coverage results with Istanbul when I used it. I wanted to create a base setup that compiled the tests and ran them as JavaScript, while still providing me with good code coverage results and the ability to debug both my program source code and test source code in VS Code. This setup achieved those goals for me.https://ift.tt/2wcuMgb you run yarn test (or npm test), the HTML coverage report generated will show the TypeScript source code:​https://ift.tt/2wkvgzO if you use the included VS Code launch configs, the debugging will let you step through the TypeScript. The fact that the TypeScript compiler generates source maps is what enables this. Most other IDEs should be able to be setup to detect the generated source maps as well:​​https://i.redd.it/lwe7wzwxjai11.png​https://i.redd.it/qaannfeyjai11.png

Refresh document before save

Hi, I have 2 functions running in a post request each of them saving the same document. The problem is that I always get a mongoose version error for one of them. This happens because the first function saves the document and therefore changes the version of it. The second one retrived the document before the first one saved so it has the old version of it, therefore when saving it throws a version error. What I tried doing is performing some operations and retrieving the document again right before saving it. Unfortunately this didn't solve the issue. I guess that both of the functions retrieve the document faster than one of them manages to save it. Is there any way to overcome this problem? Thanks on advance :)

Insight on security question

Hello, I am doing a penetration testing on an app built on nodejs, angular and express. The app does all the work through api calls using json format I was looking at ways of passing my own objects and see if could get that object deserialized I'm not a savvy nodejs and since this is Blackbox testing I can't figure out what is going on. When I pass an array as value for a variable I get an error can not cast variable name of type String/enum so I'm guessing the app is doing type checking before processing, however if try to pass constructor as a variable name I get an error can not cast constructor of type undefined so I'm not really sure of what is going on. On some fields username for example if I pass an array instead of a string the username changes to [object : object] does that mean the app is not type checking that field? What are the best practices to enforce secure input? What are your assumptions about this implementation? Thank you in advance

mock-require bleeds between test files

Hi, long time lurker here.I have a small node app that synchronizes data between two api's and I've been writing tests for it using mocha, chai, mock-require and sinon. To import modules in the app I use require, and to mock this I have opted for "mock-require". My problem is that the mocksetups seems to bleed in to eachother. The only way to run the test is to comment out all the other tests than the file I am working on.I use the mocha lifecycle method to stop all mocks after the tests have finished and have also tried using the sinon sandbox without luck.How do you guys set up your tests in node? Is there an alternative to mock-require that might work better for me?Thanks

New library to interact with all cloud storage providers: SMCloudStore

Hi /r/node!Sharing with you SMCloudStore, the latest thing I've been working on. This is a Node.js module to interact with multiple cloud storage providers, including AWS S3, Azure Storage, Backblaze B2, Google Cloud Storage, and Minio (self-hosted S3). I just published version 0.1.0, which is the result of three weeks of work.While SMCloudStore is not the first library out there to provide an abstract interface on top of cloud storage, this has some interesting features:The library itself is very lightweight. Each storage provider is published as a separate module, so you don't need to install the SDKs for dozens of cloud providers just to use one or two! (each SDK can include hundreds of NPM dependencies!)Stream-first approach. While you can also work with strings and Buffers, the library is optimized to upload/download objects as streamsStorage only. I'm not trying to recreate something like libcloud: I'm focusing on storage only to keep things simple. In fact, storage is the most common service used on the cloud, and each provider's APIs are different and incompatible.Modern APIs that support async/await (but code is actually written with Promises to support older versions of Node.js)It's all written in TypeScript (and transpiled to JavaScript), so full typings are available too.Project is on GitHub and released under MIT:https://ift.tt/2w7WVEV, full documentation is available too.

Looking for help on how to improve my codes execution speed

Dear node-community. I currently have a bot running, that tries to buy stuff from a site when certain criteria is fulfilled.The workflow is: My software is listening to a websocket, it shoots jsons whenever something happens on the site. I make objects out of those jsons and compare them with a hashmap, if price is < that, i am making an api-call to buy.That api-call is made over https, so in order to not have to build a completely new connection, I am utilizing „keep-alive“. In order to having an alive connection, I am making periodical calls to another api endpoint.The software is on a nano droplet, and that is located in the server farm of that site. It runs on ubuntu 16.04.I am looking for ways of how to improve my software. Any Ideas are greatly appreciated!

How to download large files efficiently?

Hello there :)For my desktop app using NodeJS, our users can download content (multiple dozen megabytes each) to use the app with.At first I went with FTP downloads and it worked well for me and some users, but others had issues with downloads stalling randomly, and not even throwing errors, even, just hanging the download process.I switched to HTTP by using got or download. Again, it worked for some users, but others have had similar issues with FTP.As a last resort, I've made a system call to curl to download the files I wanted, and again, for many users it solved things, but lately I've had a few reports of curl not even starting up, and the download hanging there (somehow, Windows won't let my node app start up curl, even though if the user starts curl separately, it works fine, meh.)As a last, last resort, I offered a rsync command to my users so they could download their content, and it worked flawlessly every single time, for everyone.My question is : does anyone have had similar issues ? Or has a recommendation on which module I should use to make these downloads safe?Something with automatic retrying, and events to follow on download progress ?I've already rewritten my file download functions a dozen times already, I'm a little fed up with that and would like to find a solution to my (users') issues for good.Any idea?

Nesting a separate Express app within a parent Express app

My portfolio site runs on Express, with a setup generated from the default options of the CLI Express app generator, so it has app.js, /routes directory, /views directory etc. Over the past month I've been producing something else, a game, which also runs on Express and has that same default file structure.How do I nest the project I've made within my portfolio site and continue to maintain independence between the two? I'd like the project to be accessible at portfoliosite.com/project.

Wait for mongoose save() before continuing

Hi, I have the following piece of code:commentsAuthors.forEach((commentAuthor) => { //some code saveUsersPromises.push(User.findOne({_id: commentAuthor.id}).then((commentAuthor1) => { commentAuthor1.comments.splice(position, 1); commentAuthor1.save().catch((err) => {console.log(err)}); })) }) Promise.all(saveUsersPromises) So basically i have an arrray of documents retrieved from my DB. I run a forEach over this array and each time i perform some operations, and then refresh (re-fetch) the current document, change it and then save it. The problem occurs when i have 2 documents that are the same. For the first it works fine but saving the second one throws a version error. I think this happens because the second document is retrived (line 3) before the previous one is saved (therefore its version isn't changed). How can i wait for the document to save before retriving another one? Is there a better solution?Thanks in advance ;)

Installing Submodule Packages

While working on a project using submodules, I found it a constant pain having to run npm i for each one anytime something changed. Especially when there's nested submodules.. I'm lazy, I just want things to work, so I built a thing. I figured I'd share, incase this is a frustration for anyone else.It's a light weight package. It's very simple require() before anything else. It will scan recursively for .gitmodule files, parse out directory paths, and then use a child process to cd into each submodule directory and run npm i. Unless --sub_reload was used, if node_modules exists that submodule directory will be skipped.https://ift.tt/2ONHd91

Learning to make packaged node apps

Apologies up front that my terminology might be a bit messy here; I'm learning a lot of programming stuff out of order.I am starting a new job where one of the opportunities I'll have is to build a handful of tools to do some automated tasks, like file management or sending control messages to pieces of equipment. It's all stuff I feel pretty confident I could do pretty effectively with node.Ideally, these would be built with a GUI instead of needing CLI commands, and would be packaged for easy installation on different systems. I can build a local server with express and a front end, but I don't have any experience packaging apps together for easy installation / running.I'm familiar with Electron in passing but have no experience. Is that the right direction to go, or are there alternatives that might suit a very lightweight app better? Are there any tutorials that might be recommended for getting started with good design practices?

Generating file w/ ExcelJS, sending it to server, and initiating client-side download prompt?

Hello,I am working with the ExcelJS module to generate an Excel file, but am having difficulty achieving the desired flow.What I'd like to have is:User clicks a button on the front-end (built with React) to download an Excel file. This triggers a fetch('/downloads/results') which is the back-end endpoint for the file creation and serving.The file is generated and gets sent to /downloads/results as the res of the get request.The user gets a download prompt from the browser on the front-end so they can decide where to save it.What is happening now is that instead of the user being prompted on the front-end, Node is just creating the Excel file in the same folder as the server file. The bit of code that is creating the file is "workbook.xlsx.writeFile('Project.xlsx')"My current code is below.Relevant server-side code block:function generateSpreadsheet(req, res) { const workbook = new Excel.Workbook(); workbook.creator = 'Project'; workbook.created = new Date(); const worksheet = workbook.addWorksheet("Definitions"); worksheet.columns = [ { header: 'Word', key: 'word', width: 36 }, { header: 'Definition', key: 'def', width: 120 } ]; worksheet.addRows(storedResults); workbook.xlsx.writeFile('Project.xlsx'); } app.get('/downloads/results', (req, res) => { try { generateSpreadsheet(); } catch(err) { console.log(err); } }) Relevant front-end code:renderDownloadButton() { if (this.state.queriesList.length > 0) { return ( ) } } download() { fetch('/downloads/results'); } I've been researching most of yesterday and today but haven't come to a satisfactory answer. I found one somewhat similar question on Stackoverflow where someone mentioned that the front and back ends were on different ports and that was causing the break with no indication of a download on the front-end; in my case, after reading that, I tried accessing the back-end server directly and the browser showed the file being downloaded, but there was still no prompt for the user to decide where to save it.I tried playing around with having the generateSpreadsheet function return a stream, thinking I could then pipe that to the res in app.get but I was getting tripped up a bit.Thanks for any insight/direction you can provide!

How to 'include' a file like with PHP and include(file), require(file), etc...?

I figure it would be as easy as using require() but that isn't working. import.js is the file I wish to include in every other file. It has all the class imports in it:/** import.js -- a collection / record of every .class.js file all in one place. */ import EventMonitor from './EventMonitor.class'; import Model from './Model.class'; import Upgrade from './Upgrade.class'; import UpgradeMonitor from './UpgradeMonitor.class'; import View from './View.class'; However, if I put this at the top of every class file which needs to import one another:require('./import'); It doesn't work. I get "View is not defined", then if I write an import statement to import View specifically in the main js file I get "EventMonitor is not defined", and so on. Is there something I'm missing with 'including' import.js in all other client-side .js files?

Sending Message to Particular User with Socket.IO

I am trying to use socket.io to create a chat app, where a user can send a message to another specific user. However, I am having trouble doing so. Here's the code:var express = require("express"), app = express(), server = require('http').Server(app), io = require('socket.io')(server), middleware = require("./middleware"), //Middleware to check whether user has logged in msg = io.of('/messages'); //List of connected users var onlineUsers = [] msg.on('connection', function (socket){ //Push new connected user to the onlineUsers array onlineUsers.push({id: req.user._id, socketID: socket.id}) socket.on('message', function(msg){ io.to(`${socketId}`).emit('message', msg); //Message to specific user }); }); //Check whether user has logged in msg.use((socket, next) => { if (middleware.isLoggedIn) return next(); next(new Error('Authentication error')); }); server.listen(process.env.PORT); There are two issues I am currently facing:I am not sure how to obtain the "req.user._id" of each new connected user. I have no problem doing so in the Express.js callback when requesting a route. But I have problem here since it doesn't have the usual Express.js callback pattern. The reason for doing so is to associate each user's id (req.user._id), which is unique in MongoDB, with their respective socket.id.I am not sure how to know what user the client wants to send messages to. I am trying to build a chat app similar to Facebook messenger, where the left panel shows the friends of the user. When the user click on one of the friends to chat with him/her, how do I know which friends the user wants to message to? I am thinking that when the user sends a message, the message is send along with the friend's id. Then the server could find the socket.id associated with the friend's id in the onlineUsers array, and then send the message to the socket.id.

Variable scope within app.get

Henlo,I am having some trouble with variable scoping within app.get code. I am declaring an array (ARRAY) at the top of the code. I am then looping through another array, and making a request for each item and pushing it to ARRAY. However, if I send an app.get response passing my ARRAY, it is empty. It only contains values within the getData code block.Since I am declaring the array at the top of the parent block, shouldn't the function blocks within th forEach loop and the getData block have access and be able to manipulate it?const app = express(); const getData = require("request"); // .... unrelated code here app.get("/", function (request,response){ var searchTerms = ["One","Two","Three"]; var ARRAY = [""]; searchTerms.forEach(function(item){ let reqURL = "APIURL" + item; getData(reqURL,function(error,res,body){ if(!error && res.statusCode==200){ ARRAY.push(JSON.parse(body)); } }); // END OF GETDATA }); // END OF FOR EACH LOOP response.render("main.ejs",{ARRAY:ARRAY}); });

What's the best way to implement auth with sockets?

I have a Vue client that talks to a Node server over a socket.io implementation. I've combed around for a socket auth implementation sample that solves this significantly but I've not come across any.Would be nice to learn how other people do this and perhaps see boilerplate code for a similar implementation, maybe with JWT?

Nodejs tip of the day. Using scripts in package.json

In your package.json file, there is a section called scripts.Inside, you can add your own scripts. The most common one is "start" script.You can specify any regular terminal commands over there.Like in this picture when you type "npm start" in the terminal, it will run "node server.js"When you have custom commands, such as the second command "dev" you can type in "npm run dev"P.S: nodemon is another package which let's you keep the server running.https://ift.tt/2wemtzl

Passing messages between redirects in Express.js

Hi. I have a route in my Express.js web server that resets a user's password. If successful, I want to redirect the user to the sign-in route and set a message that informs the user that the password reset was successful. To do this, I use the express-session module in the password reset route to create a session with a signinMessage property, and then I redirect the user to the sign-in route. In the sign-in route, I check if the message exists, and if it does then I extract it from the session, and then I set the session message property to undefined to clear it. See code below:router.post('/auth/reset-password/step-2', (req, res) => { req.session.signinMessage = 'You successfully reset your password.'; req.session.save((err) => { res.redirect('/auth/sign-in'); }); }); router.get('/auth/sign-in', (req, res) => { const message = req.session.signinMessage; if (message) { req.session.signinMessage = undefined; } res.render('auth/signin', { message }); }); What I'm wondering is; is this the best the best way to do this, and also, is setting the signinMessage property to undefined enough or should I also destroy the session somehow?Any advice or constructive criticism on my code is appreciated.

NODEMON — app crashed - waiting for file changes before starting

Guidence trying to trouble shoot weird error with Objection & Node Postgres.

Hey all I am running into a bit of a strange error with Objection and Node Postgres. When trying to insert a record I geterror: relation "agreements" does not exist however the information is actually inserted into the corresponding table ( ie. the agreements table in this case). Queries to select records work as expected. I'm at a loss as to why this happens, as this error happens with any model not just one specifically. It also only occurs when I bind a new Knex connection to the model. (This is a multi-tenant system, with each tenant having their own DB).The fact that select queries work has me comfortable that the connection is not the issue, like wise with the fact this happens to every model that is connected using Model.bindKnex(connection). Models that use the default connection work just fine as expected.Any help/guidance would be much appreciated.Thanks!

[Question] About Telegram (Telegraf) + Object inheritance

Greetings,I am making a Telegram bot using Telegraf.js framework.The architecture I am using is the following:- index.js is where the telegraf.js is initialized and when the bot receives a Telegram message an instance of the object ctx is initialized. To reply to the message we must call ctx.reply("string").- folder /replies/SOMESCRIPT.js is where I plan on developing all the replies/commands of the bot. I have designed it this way so when I want to add/delete/modify a module - all I have to do is to edit or create a file there and everything will be loaded dynamically on each message that the bot receives.- every reply/command must have the "exports.main" function which will do stuff and return the answer that the bot will give.A sample code from index.js:let currModule = require(repliesDir + replyName + '.js'); ctx.reply(currModule.main(ctx.message['text'])); // This is in a try/catch if the require fails it replies that there is no such command. A sample code from hi.js:exports.main = function(message) { return ("Hello!"); }; Everything works great, but the problem comes when I want to return something different than a string. For example - Telegraf uses ctx.replyWithPhoto to reply with a photo, but I am calling the ctx.reply in index.js and there is no way that index.js can know what type of answer will the other script's main function return.I was thinking of passing the ctx object instance in some way to hi.js so it could reply from there and this way index.js will be used just as a wrapper as it is supposed to be, but I can't thing of a way to do that.I do not have that much experience with Node/JS and I would like to get some recommendations on how to accomplish this architecture.

How to associate uploaded image to existing asset?

Hi,I am developing my first app so bare with me.. I have a post route to upload images to my server. I would like the image to be attached to a particular asset. The asset already exist, I just want to update the record with the file name so I later can fetch the image for that asset.I am unsure how I should do this. The example code below is how I have tried to solve it so far and it does not actually work properly, i get errors in chrome console, complaining about mime type... What I am trying to do is send image to server and then update the record of asset id with the filename. But then I am doing both a post and put request (kind of) in the same route. What would be a good example dealing with it? The asset already exist so its an update on the asset but a new post request for the image. Does anyone have a recommendation?router.post('/:id', function (req, res) {upload(req, res, function (err) {if (err) {res.render('../views/pages/map', {msg: err});} else {if(req.file == undefined){res.render('../views/pages/map', {msg: 'Error: No File Selected'});} else {queries.updateImgName(req.params.id, req.file.filename).then(function() {res.render('../views/pages/map', {msg: 'File Uploaded!',file: \uploads/${req.file.filename}` }); //need error handling here if db was not updated }) } } }); });`

The "uws" NPM deprecation response

Why hello there,I've heard through the grapevine there's been some lively talks and speculation regarding the recent NPM deprecation of "uws" module. I've somewhat read the three threads here on reddit:https://ift.tt/2vJmbBs Q & A:Why was the NPM module deprecated?I've felt for a long time that the NPM registry does not respect my decisions to control the project in ways I want to. In my view NPM should merely act as a hosting service and host my verbatim content. NPM is not as liberal as I would like to. I don't care for third parties who enforce decisions in areas where they should have no say. NPM should host things and let the market control itself. Also, their terms of use is an American nightmare: Unlimited, eternal, indemnification liabilities + inability to ever delete, modify or republish = unacceptable.What happened to the project?Nothing. Nothing at all happened. It is still used and last version is available on NPM just like before. It is marked "deprecated" but that doesn't mean you can't use it until next version is released. I never deprecated "uws". I deprecated all versions currently on NPM because that's the strongest hint I can leave there before deleting my account.Why are you such a cunt-bastard-moron chicken-fucker sabotaging prolapsed anus hole?Thanks for the nice words. So I realize that my patch update affected more people than I anticipated. My strategy was to post a "broken" patch version with a sorti message so that the 10 or so people who are on latest got the message and spread it. I kind of misjudged the number of people sitting on latest, obviously. But hey - the strategy worked and people got the message. Libraries.io statistics are obviously not that reliable!He's a dickhead cunt face asshole elitist fuck bag.I would argue you're wrong. Maybe it's your attitude. Why would you even write such a thing? Obviously there's some anger problems here. There are 151 commits from third parties in the repo which I have merged with positive feedback. For every merged PR there are 10 unmerged ones though, so generally negativity is abundant and frankly most PRs are really really really bad and completely incoherent. If you want a nice response then write good code, provide good issue reports and behave. I don't merge PRs I don't agree with and I will instantly close any CMake PR, just like I've done some 100 times already (with increasing neglect).When will next version be ready?When I feel it's ready. If you want a time estimate or come with opinions you can sponsor the project. I don't write code for you, I write it for me and my sponsors. Unless you're saying bring back slavery, don't take the freedom to demand anything for free. You did not pay for this, thus you have no say whatsoever. Saying "thanks" in a mail does not constitute an actual thank you.Why did you nuke the Node.js repo?I didn't. It is hosted as a fork at many places on the internet and I have a copy on my computer. The reason I removed the repo from uNetworking is because I am in a transition phase where it will be rewritten and majorly improved for next major release. You need to nuke your code from time to time you see. Keeping old garbage code is not what I call evolution.Why are you writing open source code?People in open source are very quick at assuming every one else thinks exactly the same. I don't. This "community" and "maintainer" lingo doesn't apply here. Reddit user "BenjiSponge" did an excellent analysis of how I work and think. I'm, unlike 90% of all GitHub users not a socialist. I don't write open source because I believe the code belongs to the public or any of those communist ideas. I write open source for two reasons: money and money. Respect that, don't project your utopian views on my projects and try and bend it around your foot.Why should I even use uws?You tell me. It's not my issue to solve. If it works for you, good. I would say at least rather use "uws" than some shitty "fork" of it. I've seen some forks before and they all end up the same: unmaintained, stagnated & left behind. Mainly because those who believe they can fork it has no experience at all in the project and no vision for it. I honestly don't get how people rather swap to some third party clone of some 4 month old version than just use the original. But hey, I don't mind. You're not paying me.Where can I get new versions of uws?New versions will most probably be released as tags on GitHub repo uNetworking/uWebSockets-node. What is currently on NPM is not in any way any less usable than before the deprecation though. With releases hosted on GitHub instead of on the NPM registry I get the control of things I want, and you get to easily install versions with the NPM client by specifying the repo and version tag (will be made clear when time is near)./ Alex
