Is storing passwords and username in a .env file a good idea ?

I am contributing to this project puppeteer-salvator which takes as input the username and password of the user, stores it inside a .env file. Then the main script is run which loads the .env file using dotenv npm package, and logs into the facebook account of the user by opening up facebook in the headless browser provided by puppeteer. I wanted to know if storing the username and password inside a .env file is a good coding practice. Will it be safe to store there? Should i encrypt my .env file?

Uninstalling packages - dependencies being updated but some node modules not being removed?

So I am starting with a blank package.json and no other files or modules in the directory. I install a package with a dev_dependency reference using:npm install myPackage -DTrying to uninstall a package and remove the dev_dependency reference in package.json using:npm uninstall myPackage -DThis works successfully although I noticed that some of installed node modules still remain, including a blank folder from the package I installed. Is this to be expected? Also how do I completely remove any folders left over from the previously installed package? Thanks.

should i be updating model files following a db migration - sequelize cli

hello all, I am getting started with sequelize and sequelize-cli​after creating a model using the sequelize-cli sequelize model:generate function, should I then be going back into the model file and updating the model columns to match exactly what I just put in the migration?​For example if I have some validations in my db table, should i add these validations (ex. allowNull: false) in the model? Should I add foreign keys as well? My gut tells me yes, but I wanted to hear some insight from others who may be more experienced than I.​I will add that without making any changes to these models, my db will return all columns, which leads me to wonder what the point of having these models are in the first place?

Building a HTTP monitor | Help figuring out how to handle multiple monitors from database

I am looking to build an application that will take some values from a database and will run a certain 'script' using the values as parameters. The application is a website monitoring one. I am looking for advice on how best to handle pulling the data (url, timeout limit, ssl check boolean, how often to check in ,1, 5, 15, or 60 minutes) from a DB (mongo) then would run the check against the site. Currently I have a basic application that handles checks of an array of sites but it currently does not pull from Mongo nor does it look at how often it should be checking the site.​The script will output and save certain data to Mongo which I then handle with my front end application.​How best should I create a node service to handle the checks? I was thinking of a redis queue but that seems to not be the best option.​I'm really lost on this as I have never had to build something that required essentially cron jobs (my script/current service used `node-cron`)

Hi NodeJS community,I am usually browsing more r/PHP related subs, but as I've just finished the Reverse Proxy feature for Devilbox and explicitly wrote a tutorial for NodeJS I wanted to share it here.Most of you have probably never heard of the Devilbox, as it is more PHP related, but give it a look:Devilbox: Setup reverse proxy NodeJSThe above tutorial let's you run the application in an already available PHP container, there is however also the possibility to attach multiple custom NodeJS container (or only one with multiple projects) to the existing stack and therefore also make use of the underlying domain name and HTTPS feature.Any feedback, specifically on the use of pm2 is welcome, as I do not have a lot of experience yet with managing multiple NodeJS projects.Keep in mind that this is just my very first iteration on NodeJS support, so give me some input here about what is usually required to make a NodeJS developer's life easier.

Unreported Error in "Testable Javascript"?

I'm working through the O'Reilly book "Testable Javascript" by Mark Ethan Trostler. I found something that doesn't make sense to me, but it is not called out in the errata for the book. What I'm looking at is on page 71, and other code from that page is noted in the errata, but the smaller snippet I'm concerned with is not. Here it is:var BD = function(dbHandle) { this.handle = dbHandle; } DB.prototype.addUser = function(user) { var result = dbHandle.addRow('user', user); return { success: result.success , message: result.message , user: user }; }; My question is, on the second line of the second block, wouldn't you have to use the instance specific database handler object such that the line should read: var result = this.handle.addRow('user', user); ??????

How can I improve this SCSS parser of mine?

I am working on a little side/pet project of mine. All I am looking to accomplish (at this stage) is grabbing a .scss classes height attribute value, from all project .scss files.I'm using the npm package lineReader to read through the .scss files line by line, then checking to see if that line has the height attribute with indexOf('height') > -1; .This is where I am concerned I'm doing some hacky stuff.With the lines that have the height attributes, I'm grabbing the height value by parseFloat(line.split(':')[1]); which returns just the height value.But part of me has a sinking feeling that there is a better way to get this as a key-pair value, rather than having to do all of that nonsense to simply get the value from the height attribute. I want to be able to modify the height value, eventually. But for right now, I just want to physically get the value, and output it to the console (for testing purposes).​Any thoughts?

2D Multiplayer Space Sim Walkthrough - built with NodeJs/React/SocketIO

Hi guys,I have put up the first parts of a 2D multiplayer space sim walkthrough using NodeJS/React/MongoDB/SocketIO that some may find interesting.http://bit.ly/2Robz6J blog parts are so far are still in the early draft stages and have quite a few things that need fixing but it will be updated weekly. Right now it is in one huge long post but I will break it into separate sections shortly.It is currently up to part 15 and my intention is to build a full Multiplayer Space RPG game, with the blog containing the posts on how to build the entire thing. On the blog you will find a link to the test server (www.cmdship.net) which runs the latest version although at present it will probably crash or be down frequently - though hopefully will be more solid in a few weeks.I began building it and making it up as I went, then went back and rebuilt it again a few times in a more structured way. It isn't intended to yet be a guide on how best to do things (and in parts may be a guide on how not to do things), more just an idea of what you can do with just NodeJs, sockets and a client canvas. It may at times just read like endless walls of code but over time I will improve the parts to include more explanation.All the source code is linked to on the blog and free to use as you like, I've also linked the source code at each part at the end of a chapter. Project source: http://bit.ly/2GPrQxD free to contact me if you have ideas for improvements or find bugs and I will attempt to implement them where possible.​​​

Any graphing/plotting packages that run out of the console, similar to MatPlotLib for Python?

I'm looking for something that generates plots directly from the console (via NodeJS), without having to code-up a bunch of HTML and whatever.A good example of what I'm looking for is MatPlotLib for Python. The plots pop-up on the screen when they are created, and halt code from executing until they are closed. The plots are also interactive (zoom, save, etc), opposed to just creating a static image.I'm not looking for plots within the console, so something like asciichart is out.MatPlotNode provides MatPlotLib bindings for NodeJS, but requires Python 2.7, which is antiquated and not what I have (currently on Python 3.7).Thanks for any insight!

Port number for Socket.io with Express on Heroku

I use the the following configurations for my node server and react client respectively;index.jsconst express = require('express') const io = require('socket.io')(8000) const app = express() const port = process.env.PORT || 5000 app.listen(port, () => console.log('Listening')) App.jsimport openSocket from 'socket.io-client' const socket = openSocket('http://localhost:8000') This works all good on the localhost. However, when I deploy to Heroku, it does not recognise the port number of 8000 and http://localhost:8000 as expected.Is there configuration to make it assign a port number automatically for the web socket, just like we do with the Express server by using const port = process.env.PORT || 5000 ?​EDIT:This article helped mehttps://devcenter.heroku.com/articles/node-websockets#option-2-socket-ioExample codeAlso don't skip this step:Apps using Socket.io should enable session affinity.

Cool! I made a modding tool for a video game with node :)

IF anyone has played X4 Foundations, (its a space sim with lots of modding support) - I got carried away with creating a "ware generator" - and dealing with X4's XML stuff. So I got to learn a LOT about xfering JSON to XML and back, used xml2js quite a bit for that, and to wire everything up to their xml system it took me about 10 days. Most of it was me creating classes with Typescript, as it honestly just helped me learn their xml schemas better (since they dont release a full schema of their objects anyway)​Some things I learned along the way:​You can use a library to convert a JSON object to a Typescript type, so if you convert an XML object to a JSON object you can get some of that IDE auto completion goodness when working with deeply nested and hard to remember objects.the PKG library lets you convert your CLI to a windows .exe file (and mac/linux binary FWIW) - which is great for making a CLI tool that is focused on a windows platform game.omg facebooks metro-memory-fs is THE absolute best at mocking filesystems, I couldn't even get other mocking fs libs to work with windows!Node has come a very long way with windows support (I generally code on a mac) - even without using the windows subsystem for linuxTypescript's module alias mapping will create outputs of files that still map to aliases, so if youre not using something like webpack (which I'm not because this is a CLI tool) - then dont bother!aside: I did find a library that let you run some require overload but it didnt work with PKGnode's ZLIB implementation is painlessly easy to use (a few lines of code to ungz files)Event Streams are still not what I thought, and I still don't understand themI've been using promises for years, and I still get surprised by their behavior. Seems like they're very eager to evaluate, even before calling them. I guess that's on purpose.XML is evil.. (not really, but...)Well, that's stuff I learned which I feel like I've learned the promise thing before but forgot it again haha.​Feel free to browse my most recent labor of love (ok that sounds cheesy but lets keep it) here: http://bit.ly/2SmUHul

I'm wondering if I should use a code-first approach for this db, and if so, what are my options with sequelize ? Is this something that someone has experience with?

Thoughts on embedding vs referencing documents for MongoDB

I'm going through a Node course, and I'm covering referencing and embedding documents. I can see for something like a ticketing system, you would want "notes" embedded in a document because they are specifically tied to that ticket. However something like a "user" that submitted the ticket could be referenced. That way is the person gets married and changes their name, the ticket reflects the change.​This is my very simple way of looking at it, do any of you folks with real world experience have any guidance on this?​Kind regards, and happy holidays.

Multithreading (CyclicBarrier) in Node.js

Hi all,I have a question regarding multithreading (I know it's technically one thread) in Node.js. Let's say I have thread A, which at some point splits off into A and B. At some point in the future, A and B merge into one thread (A) again. But here is the issue: if subthread A finishes its work first, it can add a .on('event') to B's EventEmitter, and that's easy to work with. But what if B finishes its work before A? In this hypothetical scenario, by the time A registers the .on('event) listener, the event was already emitted, and thus A would have missed it, resulting in the program locking up. My current workaround is checking for a boolean being true first, and only after that registering the listen event, but 1) that is ugly; and 2) it is not 100% safe due to the lack of mutex in Node.js. Am I missing something here? Is someone willing to point me in the right direction?

sync() method provided by sequelize required in production but not locally

hello all, I am new to the backend and to node. I'm using express and sequelize as my ORM.​Locally, I've created an API that connects to a postgresql db to handle my info. this works fine, and I had no issues reading and writing data. I also did not need to use sequelize.sync.​Move forward to my production server. during the deployment process, i received an error saying that a table from our db script did not exist. to fix this error, .sync() was used and now this works on the production server.​I'm wondering if anyone more experienced than me could help me debug:why the table was not created from a postgresql db backup,what the sync method is fixing in production, but not needed for locally.I should also add that I'm using sequelize-auto, running db first .

Does typecasting exist in JS?

I am writing to a NoSQl db (Nedb) and when I pull documents out, they are no longer defined by their type or constructor. What is the protocol? In Java, you can typecast upon deserialization to obtain access to the object's methods and properties. Not sure how to go about this in JS.

Caching cloud data via a custom node server?

For an upcoming project I'm using a cloud database (Firebase Firestore). It works great, but my concern are potential high costs in case of high traffic to the site.​To keep the costs down, my idea is to avoid fetching data from Firebase directly in my frontend (React) app and instead:- create Node scripts that will pull data from Firebase and save it to local JSON files on my server every 15 minutes- create a basic Express.js API that will serve those local JSON data to my frontend apps​Is anyone doing something similar? My data doesn't update often, so making read requests to Firebase every 15 minutes is fine and would be a huge cost saver compared to making read requests for every single visitor.​My main question for the Node community, is it a good idea for my custom Express API to use "fs" to read json files and serve them? It seems redundant to use a local database as well, but I'd do it if it would be better for performance in case of high traffic.

Is it inadvisable to export request handlers as objects?

My first post here, thanks for the help in advance.So I am working on the backend of a product that uses node+express and was developed as part of a hackathon, much before I joined the team. The code was riddled with malpractices and pitfalls, which is why I was tasked with refactoring the code to meet enterprise standards (It is primarily a B2B app).One of the conscious decisions I took to make the code look cleaner and more modular is have the routers (like app.get('endpoint'), (req,res)=>{...}) in a different file and the actual request handler functions (like function createEntity(req, res)) in a different file, grouped based on what virtual data entity they operate on. I am doing request validation in the router and calling the request handlers only when request has been validated.The thing is, I am exporting the request handler functions as key-value pairs in a JSON object like so :module.exports = {createEntity: createEntity,getEntity: getEntity};I just had a round of code review by my seniors and one them, having about 7 months more experience than me in the team, raised the issue that what I am doing is unwittingly implementing a "Singleton" pattern, which I know node does by default, but according to this article should be done only knowingly. My manager says his point "makes complete sense".My question is, do we have to put an effort into not exporting objects in case of request handlers which are bound to a specific path in the API and won't sensibly be required (imported) in more than one place? If yes, what would exporting a constructor look like in this scenario.Edit: grammar

Send message to a specific worker from master?

So I had an IRC client in python and it was using way to many resources, so I switched to node. I converted the code and was trying to figure out child processes then found my way to forks. I eventually found out about clusters and that seems like my best option, but I have a question.I have been trying to figure this out for a while and don't know if this is actually going to work.1.) Many people need to send a message from the worker -> master but I need to mainly send data form the Master -> worker. Most examples only display sending from the worker at the main source of sending, am I doing something wrong here?2.) I also need send these commands to specific worker (I just found out you cannot Or at least I think send data to a specific forked child processes hence the reasoning to look into clusters). I know that3.) These commands send to the worker are commands to disconnect from a certain IRC. Would that work?

Sending data onto the client after authentication using express.

This may seem like a nooby question... But it's a scenario I've not yet encountered.Normally when I write my server code it's responsive, in that it simply replies to user requests. But this is different.I have a callback endpoint that will extract an access token. The problem I'm facing is that because the user never makes a get request, and that wouldn't really work even if they did, I don't know how to correctly send across and receive that token on the client side.So I can do a res.send() and that will send the token information to the user to be automatically rendered on the page. It's not what I want, however. I want the client to get the access token, but not display anything automatically. I suppose I could use res.sendFile() but this and res.json() both bring me to this problem:How do I listen for these? Since I'm not fetching and using a .then(responsedata), how do I get the response?​tl;dr: how can I send data to client without fetching it or displaying it with res.send().

How to manually check hashed password stored with Passport.js in MongoDB database

So far I only have this way of verifying if the user entered the password correctly:// Login routes router.route("/login") .get((req, res) => { res.render("login"); }) .post(passport.authenticate("local", { successRedirect: "/", failureRedirect: "/login" })); I want to add a feature where the user can change the password and I have two inputs: old-password and new-password. I need a way to compare the hashed and salted password in the mongodb database and the one that is a string from the old-password input. If the passwords match update the password in the mongodb database with the new-password.Basically I need a function like bool password_verify ( string $password, string $hash) in PHP.I am using passport, passport-local and passport-local-mongoose for my user authentication, everything standard.

Server-side TypeScript framework

Hi guys!I am currently working on the server-side TypeScript framework. My team already widely use this framework in various e-commerce and ERP projects. Structure and semantic were inspired by other popular frameworks like Spring and ASP.NET.Currently, there are a lot of possibilities:Describing routing using controllers and decoratorsPowerful, full-typed Dependency InjectionIncoming data validation (using AJV) with various set of decoratorsTypeORM integration (Repositories injection, Transactional support using CLS)Extendable JWT-based authenticationAll parts of the framework are fully typed and integrated with the whole infrastructure.For the best performance, under the hood, Fastify is used. The framework is declarative, but also avoids using decorators were it's possible. So, it's keep everything simple, clean and minimalistic.Example:@Controller('foo') export class FooController extends IController { @RoutePatch('{id}') bar(id: string, payload: FooDTO) { ...some updates.. return Ok(); } } So, as you see, there no need to provide any additional param decorators for injection data from the HTTP request. It's just a small controller overview, there are a lot of other possibilities.Features coming soon:AOPGRPC integrationGraphQLCLIand more...From the beginning, the framework was designed as opensource. I really need your feedback guys, it's very important for me!Here the few links:Github - ODIDocs - ODIAlso, we aim to support Deno in the future.Thanks for your time! :)

I did install node per instructions on Google's site for Windows, but it just seems like at least package.json should not be there... not sure if I did something wrong, nor why node_modules would ever be installed there. I'm not familiar with the Linux/Mac way it installs either, but I've only used npm (not yarn, which I think isn't even compatible with Windows yet).Please, if your answer is to get a Mac or Linux, I'll set up a GoFundMe link for you to contribute to.I also installed Git Bash from Git Extensions (awesome program), which I know has "global" config in my Users folder, so is package.json node's "global" file? It seems that could conflict with other programs' "global" package.json file if that's what's actually happening.

Mongoose findOneAndUpdate can't take an object?

hello all,​I'm working on learning how to build API's and I'm having some trouble with my PUT. With my POST I can do something like:​const userToAdd = new User({firstName: req.body.firstName,lastName: req.body.lastName,password: hashed,email: req.body.email.toLowerCase(),address: req.body.address,city: req.body.city,state: req.body.state,zip: req.body.zip});let result = await userToAdd.save();​The above works just fine, however when I try and do a findOneAndUpdate, I have to break out each field instead of just creating a new User object.​const user = await User.findOneAndUpdate({_id: id},{firstName : \${firstName}`,`\lastName : `${lastName}`,`\password : `${hashed}`,`\email : \${email}`,`\address : \${address}`,`\city : \${city}`,`\state : \${state}`,`\zip : \${zip}`},`{ new: true })\`​I expected I would be able to do something likeconst userToUpdate = {firstName: req.body.firstName,lastName: req.body.lastName,password: hashed,email: req.body.email.toLowerCase(),address: req.body.address,city: req.body.city,state: req.body.state,zip: req.body.zip};const user = await User.findOneAndUpdate({_id: id}, userToUpdate, {new: true})​kind regards

How to get data from another file?

So I have been searching over internet for more than an hour now but couldn't find a good answer and wanted to ask here as well. Please keep in mind I am fairly new with node.js.My problem is, I have one .js file that is a chatbot and actively listens user texts on the platform. And it checks "if message == some_pre_defined -> write pre_defined_response". Now I can do this and it works pretty well. However, I have the message / response list on the same .js file as well.What I want to achieve is, have two files, and keep commands/responses at one of them, and use the main one to call different functions. So, it would be like this,main.js -> functions/other stuffcommands.js ->const responseObject = { "ayy": "Ayy, lmao!", "wat": "Say what?", "lol": "roflmaotntpmp" }; Then I want to call that constant from my main file. Currently I have that command list in my main.js file, so I can call them & use them no problem. But, is there a way to call that variable from another file? I know that functions could be called with "require" but I haven't find a way to call that constant/variable from other file and use it actively.

Proper way to release a Postgres Pool connection

I'm learning about PgSQL pooling. I wrote a script using the node-postgres package. Currently it successfully grabs a connection from a pool of 5, executes a query, gets results, and then I'm not sure how to properly release it. It's just a script and I'm running it using node index.js. But when I use pool.release() the script takes longer to exit than when I use pool.release(true). Which way is will release the connection back into the pool, and can you explain the difference between them. Here's a link to the documentation I'm referring to http://bit.ly/2EIf6WN.

Good programming practises for storing / displaying data?

Hey guys, I am a cs student and still learning so I apologize in advance if this comes off as a little simple. Also if this is the wrong sub, I apologize but I think Electron runs on top of Node.jsI have an electron app and am storing data in a NoSQL db, NeDB (something like a NoSQL version of SQLite) . This data is also being displayed on screen. Should IStore everything in memory, display the changes as they occur, and write to the database upon exiting the program?Read / write to the db, and pull data from the DB to show to the screen?Hold the data in memory (in some variable) so I can display it on screen, and also continuously add to the DB as it is updated?The first option seems a little unstable as obviously, if the program crashes, you could lose a good chunk of data if you've had an app running for some time.The second option - I'm worried whether or not this would be too slow / redundant to both write to DB and then pull it back to display to screen? I think NeDB stores the whole thing in memory anyways, so it's less about the efficiency and more about just plain code redundancy.The third option - I don't know why I thought it was any good when I was running through options but I think I had some logical reasoning behind it at the time.Any help would be appreciated!​

How to save uploaded files on a disk

I wrote a very simple file uploader, which calculates hash of the file content, adds it to the file name (so that files with the same name do not get overwritten, but if the same file is re-uploaded it overwrites the previously uploaded file), and saves the file in the root of the specified directory.There are a couple of problems with my super-naive approach.First, all files end up in a single directory. Presumably, as the number of files grows, this can slow down the time to access files. I googled for a good solution, but found only this article on Medium discussing how to build a directory structure out of the hash of file name. Is this a standard approach? Do you know of any pre-existing packages that already do something like that?The other problem is that calculating the hash of file content takes a long time if the file is large, and this CPU-intensive operation blocks the main thread. What is a good way to offload this operation from the main thread? (Sorry for asking such a noob question.)

Converting Promise to ASYNC / AWAIT

Hello all,I've been working on using ASYNC and AWAIT, and for some things it seems to be working just fine. However I'm running into a specific problem I don't understand. In the code below I'm saving user data into MongoDB via Mongoose.​This code block works fine:const addUser = async (firstName, lastName, email, password) => {return new Promise((resolve, reject) => {const user = new Users({firstName: firstName,lastName: lastName,email: email,password: password,isPublic: true});const result = user.save();if (result) {resolve(result);} else {reject(err);}});};​This code block does not:const addUser = async (firstName, lastName, email, password) => {return new Promise((resolve, reject) => {const user = new Users({firstName: firstName,lastName: lastName,email: email,password: password,isPublic: true});try {return await user.save()} catch (error) {return error}};​I am under the impression that when you 'await' the promise, it's handing the resolution for you. Is this not correct? I know the try / catch sequence is handled, but do you still need to resolve or reject the promise? It's looking like you still do. Also is there a "better way" than a simple if statement to check the promise's resolved condition?​Kind regards​

Issues with login and authentication in PASSPORTJS

Hey guys :)I am having some issue with my application. I have two different logins in this application, and I am using passportjs and express-session to handle it. However, I am having some issues:One login refers to a model called "user". This login works perfectly.The other one, is a model called "employees". I made the "employees" routes a mirrored version of the "user" routes, since the "user" is working fine.The "employees" login works fine, but, after the login, req.isAuthenticated() is false (it means, login is not working that fine lol), then, req.user is undefined. I don't have this issue when I do the login for the "user".I have created two different strategies for each model, and two different instancies of passport to handle each of them; It still does not work properly.Here are some images from my code:App config related to passport and the models. I have two strategies for each one, as well as two instancies of passport.​Passport configuration​User model​Employee model​User register and login routes. This one works perfectly. No problems at all! (ignore the get route for /protected, that was made only for tests...)​This is the employee register and login routes. The registering is working fine, but not the login. After I do the login, it is like nothing happened at all...​Thank you guys for the attention! I have been struggling with it for some days, and not even stackoverflow could help me on this..

My book Data Wrangling with JavaScript has been printed!

The world of data is big and it can be difficult to navigate on your own. With data all around us growing at an ever-increasing rate, it’s more important than ever before that we are able to deal with data effectively and efficiently to support our businesses and our customers, to be able to monitor and understand our processes and enable faster and better decision-making.When I started working with data in JavaScript there wasn’t much information or resources out there, I had to learn it for myself. I wrote Data Wrangling with JavaScript in the hope of making life a bit easier for those that come after me. I’ve already blazed these trails and in this book I share my years of hard won experience with you.Read more on The Data Wrangler: http://www.the-data-wrangler.com/data-wrangling-with-javascript-printed/​​https://i.redd.it/8b8yz5f0ii521.jpg

How to drop multiple databases at a time via MongoDB Compass

Totally a noob question, and I know this is typically not something you'd want to do, but I've been taking a MongoDB tutorial course which includes Jest testing and for some reason the test suites have been generating hundreds of DBs that are now showing up in my compass. I have about 502 DBs and I only care about 5 or 6 of them. Manually dropping each one sounds tedious and I feel like there's definitely got to be a better way but google hasn't helped me out very much. please help a brother out.

point me in the right direction for some node technologies

Greetings all.I am coming from a rails platform with a simple API that I am moving to node.jsI have an app built in React-Native with Expo. So here is my issue.I use Mobix to handle state on the app. I like it a lot. Actually, the whole idea of state changes updating the view instead of page refreshes is just awesome to me. However, our company allows our clients to control industrial machines with our app. Right now, to get the change of state of the machine, I am making lots of calls to the API for updates from our server. For example, if a customer presses "start" on the app, it takes a minute or two before the machine is running and our database knows about it. I don't want the app repeatedly making calls to the server to check if its running or not. Push notifications seem to be an idea but also seem a bit overkill. I have looked at Socket.io, but am not sure if it was really meant for a task like this, to push information to the App. So this is one area I am looking for an answer to.The other thing is our data processing. When a machine reports to our system its state (running, off, idle, etc..) we do a lot of processing on it's sensors (pressure, current, etc) to properly know the status of the machine. We log it's history, running time, etc.. I am starting to write more of this process in node.js and would like to share some code between the webserver code and the engine code because a lot of it is similar. Would a framework be better suited to something like this? (currently using Objection.js as my data interface and Express as the api server) . I mean, a lot of things the app needs to know are the same things the machine processes need to know. But our machine process sending requests to our api server would (because of http) be quite overkill and i wonder if it would even be fast enough to keep up.I am reading lots of articles about data mappers and socket servers and was thinking perhaps an idea might be to have functions in the API that pull (via tcp) info from our machine processes code that make use of some of the same data mapping before sending that result via JSON to the client. Or is it a better discipline to keep these separate for the sake of maintainability?So, I guess my questions are about technologies I may not know exists, or best practice kind of questions. Sorry for the long post, any ideas would be very helpful and well considered.

Announcing Gluegun 2.0 — A delightful way to build command line apps in Node

A couple years ago, we (at Infinite Red) built an NPM package to help us build out some CLIs in Node. We called it Gluegun.I've been putting a lot of work into it over the past year and finally have version 2.0 to show. So, here's a blog post announcing it!https://ift.tt/2QD7s7r few notes:We know there are a lot of options in this space. Yeoman and Commander.js are probably the two biggest.Gluegun sort of wedges itself into a unique space -- it is powerful (comes "batteries included") enough for most CLIs you might have to build. But it doesn't take over your world like Yeoman does.It's used by AWS Amplify's CLI, Infinite Red's Ignite and Solidarity, and several others.Happy to answer questions here if you have any!​

what is the difference between a DataMapper and an ORM

I have been reading about different ORM's (I use a mariadb-cluster) . And there is much mention of datamapper as a design. After reading several pages, I can't really see the difference. Any ideas?I am using Objection.js right now, which is working really well for me. But I thought for more complex relationships for an API I need to build, another paradigm might make it easier. I like the idea of making a restful interface, but none of the info I want to build routes for are as simple as pulling rows from a database based on queries (where an ORM would shine, i think) I mean, would be ideal for a document storage db, however, all our data is in mariadb tables.​
