Returning the result of a promise loop up one function.

I'm new to promises and working on my first project using them. I have following code ; firstpromise.then(function(result) { //console.log(result); return secondPromise(result); }).catch(function(result){ //console.log(result) }).then(function(result) { //console.log(result); return exportname.iteratePromises(result); }).catch(function(result){ //console.log(result) }); exports.iteratePromises= function (object) { new Promise(function (resolve, reject) { for (var i = 0; i < object.array.length; i++) { doNewPromise(object.array[i], object) if (i + 1 == object.array.length) { resolve(object); } } } function doNewPromise(args, object) { // is a method in the thirdPromise export file new Promise(function (resolve, reject) { request(headerOptions(args), function (error, response, body) { if (!error && response.statusCode == 200) { var result = JSON.parse(body); doStuff(); } console.log(object); resolve(object); }); }); }; So at the stage of iteratePromises I'm calling the for-loop which in itself does a request to an API for each element in the array. That request does something with the object successfully.If I console.log the doNewPromise before resolving it, it returns all data that is expected for each iteration within the array and the object is manipulated successfully.The problem I'm facing now is that I don't know how to pass that object (the one in the for-loop) back to the promise chain once all iterations have been finished.In short, how should I store/declare the returned promises from the iteratePromises execution back to the promise chain?I have tried to end the loop by usingif(i == arr.length){ end and resolve } but that keeps on returning undefined objects.I'm really at a loss as to how to approach this and any help is very much appreciated .Thank you in advance,Hexerin0

[question] how to call a slow process

More specifically I'm making a file uploader for a mate of mine and naturally I need to scan the files that gets uploaded. Now he has something called sophos to do so, and it works with this command/opt/sophos-av/bin/savscan -nc -nb -ss -remove -p=$transpdir/last_scan.txt -archive -suspicious *file*Which I've tested and it works (I even know the exit status for virus found and clean file (3 and 0 respectively)) but the problem I have is it takes a few seconds for the the command to work. Now I'm considering calling the command herehttps://github.com/inabahare/lewd2/blob/master/src/Routes/upload.js#L87but I'm not really sure how I would go about it

NodeJs instead of Django / Spring??

My goal is to be able to launch web apps that are scalable using DRY principles with good libraries to use. I know Django, Spring, Java Python (amongst other things)DjangoI've used Django to launch my own web-apps before on a PaaSI'm familiar with the architecture (MTV) and love how it handles a lot of the things for meI'm not as familiar with Python as I should be (classes etc). I'd need to take a refresher course before I begin focusing further on DjangoSpringNever used Spring or Java for web developmentGood knowledge of Java / OOP design principles (2 semesters at college + self-study)Stronger foundation in Java makes me more confident to learn SpringWhat I am not sure ofIf it's even worth it learning spring when I already know DjangoIf Django / Spring have any high-level limitations or specific benefits / use casesWhether any of these will be harder in terms of difficulty but also AWS integration (I'm working on an AWS project at work and learning AWS along the way)But then I flirted with the idea of Node.JS and going full-stack JavaScript. I've worked with JS before, and the benefit is that it operates with HTML5/CSS quite nicely, which means it is easier for me to keep my HTML/CSS skills sharp. It simplifies my study plan greatly. I'd love for the idea to specialise in one thing (Right now I'm a generalist jack of all trades).Are there any downsides associated with full-stack JavaScript?*My interest is not in being a programmer or a career or whatever, I work in cybersecurity, I simply want to have an idea and want to be able to implement it to the best of my capability. That is all :-) *

Appropriate way to store files? (Rest, API, SQL)

Hey,I'm developing a REST API which accesses another API (for the sake of simplicity I will refer to it as the 'remote API') to retrieve data and store it into a database. In this context the data represents a file, which is represented as an byte array: the remote API is written in Java, where it parses a file into a byte array and serves the byte array as the response to the GET request of the REST API. The current implementation looks like this:REST API makes a GET request for a specific file.Remote API receives and parses the query (where it finds information about the desired file).Remote API parses the requested file as a byte array.Remote API sends the byte array as a response back to the REST API.REST API receives the response.REST API stores the byte array into my postgreSQL db.Later on the REST API should serve the stored data (decoded) to my frontend, written with react.js.Each file is around 5MB and represents ~ 5'000'000 characters. Given the above implementation, accessing a single stored file takes around 3 seconds. The response looks like this:{"data": [{ "id":1, "name":"file0", "content":{ "type":"Buffer", "data":"Content of the file..." }, "createdAt":"2018-06-29T10:17:17.829Z", "updatedAt":"2018-06-29T10:17:17.829Z" }] } Based on this, I have a few questions:What is the standard in the industry to store files?Where do you prefer storing files (refer to the question below)?Is it bad practice to store 5MB files into a single column in a db (currently I'm storing the content of into a single column for each file, of type bytea)Also, I believe the read process of a stored file takes no time, however the display of the files content does. I tried returning only the content of the stored file, without any other information (non-JSON), which lead to Chrome starting to download automatically the returned data (as you would download anything). This happened immediately, that's why I believe, the retrieving from the db isn't an issue.Am I wrong on this?Given that I would return the content, without any other information as shown above, how would I access the returned data on my front end (e.g. to display it in a table)? (since I'm not returning JSON, how would I access the data?)If you have any other suggestions, I would appreciate your help :)

Client/Server Node Implementation

Hello all,I am fairly new to Node and web development in general, so I'm still learning this framework among others and how to structure a project directory. I am currently developing a personal project that implements Node for the back-end and Vue for the front-end. My project's current directory is simply structured as such:> App--> Client (Vue)--> Server (Node)My question: Should I npm init in both the Client and Server folders to have each end of the project use their own node_modules or should I npm init in the parent directory to have them share a common node_modules folder?I plan to host my project on Heroku and from what I understand you have to host the front-end and back-end as separate "apps", where the front-end calls the back-end for data. So this makes me think that you would need separate node_modules.

decoding array of utf8 strings inside a stream Ask Question

I faced a weird problem today after trying to decode a utf8 formatted string. It's being fetched through stream as an array of strings but formatted in utf8 somehow (I'm using fast-csv). However as you can see in the console if I log it directly it shows the correct version but when it's inside an object literal it's back to utf8 encoded version. var stream = fs .createReadStream(__dirname + '/my.csv') .pipe(csv({ ignoreEmpty: true })) .on('data', data => { console.log(data[0]) // prints farren@rogers.com console.log({ firstName: data[0] }) // prints { firstName: '\u0000f\u0000a\u0000r\u0000r\u0000e\u0000n\u0000@\u0000r\u0000o\u0000g\u0000e\u0000r\u0000s\u0000.\u0000c\u0000o\u0000m\u0000' } }) Any solution or explanations are appreciated.Edit: even after decoding using utf8.js and then pass it in the object literal, I still encounter the same problem.

Question: can Redux (or redux-persist) be used for event sourcing?

I was thinking about implementing CQRS and event sourcing to my backend. Redux (a front-end package) struck me as a very similar concept to event sourcing.Do you think it would be feasible to use Redux on backend to deal with the state and persist the events to something like Redis while saving the last known state to MongoDB (for easier querying)?

Hi everyone,I'm looking for finding the best practices for the design architecture of Node Programs. Currently whenever I am writing a node Application I have a directory structure like:app.js[app.js requires all modules from /classes and uses them to make API endpoints. All my .get .post .put .delete endpoints are all in one file.]/classes[All modules each using 1 mongoose schema and defining functions go in here]/util[Any sort of module I use for logic in special use cases]I'm looking for articles/github repositories demonstrating how this should properly be done such that everything is modular. Is instatiating an express server and then having all app.get app.post app.put app.delete methods in one file. For whatever reason it just seems wrong to me?To any more experienced devs who frequent /r/node, how do you handle this?

[Question] writing post request without route

So I feel like a total noob for having to ask this but I have never had to write a request without it having a route. So basically I need to call a post request periodically to get a new bearer token from a service to be used in all my API calls. During the development, I have just been using Postman to get a new bearer token and just hard coding it in. Now that it is going live I need to automate that.At this point, I am at a loss as to how I would structure a POST request without a route. This is just going to be triggered server side without user interaction.I know this is pretty vague and I am probably missing some fundamental understanding but I can't find anything from googling that refers to what I am trying to do(probably not asking the right questions). If anyone could point me in the right direction it would be greatly appreciated.TL:DR - Need to make post request to get new bearer token from service to use in my API calls. Not sure how to do this without using routes.

How can I send a data to a client (React app) which I received from a python app?

I'm creating a server to send data to the React UI which I'm receiving from a python app. Python app is not a web app. It's just a script. What I'm doing is I'm sending a JSON object to a route from python when the script is executed. Then I need the react app to receive the data and render it in the View. How can I do that ? I created a route and made a POST request from Python script to that route so I receive the data in the node. It works, what I need now is to send a POST request inside that POST request (which I receive data from Python script) , As making a POST request inside another POST request is impossible, how can I do this ?This is my route which I receive data.app.post('/getdatafromapp', (req,res) => { console.log("Got data"); let data = req.body; console.log(data); res.send('Hello'); });I need to make a POST request with data (req.body of the above POST request) as the body, to React frontend. How can I do that ?Any help would be appreciated. Thanks.

How to query(express)?

Hey,so I'm about to implement querying to my API and read about some possibilities in this article. Since I'm using Sequelize.js on my backend, I tried the LHS approach, which worked out perfectly combined with the operators provided by Sequelize.jsAn example:/user?id[gt]=1&id[lt]=3 would result in (using qs)id: { gt: 1, lt: 3 } which I could simply pass in to my Sequelize.js where statement (keep in mind I used aliases, as shown here (without the $, though):User.findAll({ where: { id: { gt: 1, lt: 3 } })} This works fine.However, as described in the Sequelize.js docs, an or statement would need to look like this:User.findAll({ where: { id: { or: [1,3] } })} Is there any way I could get this by using qs?When I try to query like this:/user?id[or]=1,2 qs.parse() returns{ id: { or: '1,2' } } Although in this case I would need{ id: { or: [1,2] } } Therefore querying like this: /user?id[or]=[1,2] results in{ id: { or: '[1,2]' } } Any suggestions? Are there other ways to implement querying? I want to be able to provide as much filter, sort, query options as possible.

Suggestions on what to use

Hi allI've been sitting here working on an app and I can't figure out what the best solution would be for what I'm trying to achieve.I have a NodeJS application that allows requests to be made to it via an API call - and what I would like to do is store the results of the API call in a database so my clients/users are able to view the hits and data in a dashboard that they can log in to.I will also be providing metrics data such as how many requests they've made and what possibly conversion rates that I will be querying the DB on.Will a simple RDBMS work or even a noSQL DB? or would I need something totally different.Just to also add - I was thinking of RethinkDB as I would be allowing the customers to sign up for web hooks and the "changes" API would be really helpful.Thoughts?

Axios response with 64-bit integer

I'm using Axios to request data from an API. The API responds with data, but the data contains a 64-bit integer ID field. JavaScript only supports up to 53-bit integers, so the last digits of the ID are rounded up (or something).Example:I send a request to the APIThe API responds with data containing ID 900,719,925,474,099,199Axios stores this ID as a Number, but because the ID is higher than Number.MAX_SAFE_INTEGER, the last numbers are rounded up resulting in ID 900,719,925,474,099,200and I'm left with an invalid ID.The first solution that came to mind was to simply store the ID as a string instead of a Number, but I don't know how to tell Axios to do that. Is there a way? Do I perhaps have to use another library? Or is there some other solution that I haven't thought of?

I even went ahed, and comparedsomeVariable.__proto__.__proto__ === Object Wich resulted in false. I googled for a bit, and found this articleBasically what it is sayng that in browser JS, there could be more than one window instance. Wich also results in false, when comparing 2 constuctors from diffrent window environment.So it might be, that i have similar porblem, but in node.

Should we stop writing to log files?

[A spin of a thread that discusses console.log leaks]My hypothesis says: We should start writing to process.stdout instead of log files. The modern deployment models, k8s and serverless, dictate short-lived hardware that gets standard input and emits standard output, sometime without disc access or with disc that dies frequently. When you write to stdout (under the hood, this is just a file descriptor) those platforms will collect and forward the entries. No additional configuration is needed. On the other hand, writing to log files demands custom configurations + mounting + assuming write permissions - we deviate from the standards that the platforms suggest. What do you think?

All of the users who were connected on that process will remain in the user list that's stored in redis because the disconnect event never fired.One thought I had was that I'd have one master process and all socket.io processes would send the information of all clients who connected / disconnected to the master process.If a worker crashed, the master would remove the users from the user list and handle it just like the worker normally would.I'm not sure if this is the right way to solve this issue, but hopefully someone here can point me in the right direction if it isn'tI'd appreciate any help you guys can give

JWT logout using blacklist method

Hello,I'm working on the authentication part of my app and have reached the part where I need to make it possible to logout. So I decided to use the blacklist method where I store the token and reference it whenever a user wants to access a secure route. I'm now using a mysql database for all the other data that is being stored.Most places say I need to create a new database to store the blacklisted tokens but can't I just create a new table inside the existing database and store them there? After they have been stored they need to be deleted (after they've expired so they don't pie up) using an SSL-option which some databases have. Does anyone know if mysql has SSL support and how I should use it?It was quite hard to find any good tutorials on logout with jwt so if anyone has any tips I would really appreciate it!

6 Reasons to Choose Node.js for Web Development

https://ift.tt/2I1aGIQ has been successful since it was launched. Many developers find it perfect for building fast, multi-user web applications. As you may know, Node is written in JavaScript.That is why it is very easy to learn if you know JavaScript. In this article, you are going to get a list of reasons to choose Node.js.https://ift.tt/2taDqKt real-time applications in Node.jsDo you want to create a chat application? Or maybe a gaming site? To build that kind of apps, Node.js is the best option for you.It is also a good choice for apps that need an event-based server and non-blocking driven servers. Popular websites like PayPal, Yahoo, Ancestry, and Quizlet use Node on their servers.https://ift.tt/2I1RKJV created fast V8 JavaScript engine for their browsers. Node.js uses it too. For you as a developer, only thing to worry about is writing proper code, and Node will take care of the speed.https://ift.tt/2taDt97 reusabilityCreating web apps in Node.js is much easier thanks to NPM(Node package manager). Developers can easily share and reuse their code with NPM. There are many useful packages out there, including packages for security, file uploading, databases and more.https://ift.tt/2M1qptM programming language for everythingAnother reason why Node is game-changer in web development is that developers can use same programming language on both client- and server-side. This feature does not only save time but also helps to synchronize different data automatically between server and client.https://ift.tt/2taDudb streamingNode.js allows you to access a particular file while uploading it. Developers who work with real-time audio or video encoding benefit from this. If you want to create a streaming app like YouTube or Twitch, it is very easy in Node.js.https://ift.tt/2I3E2WK is the most popular Node framework. Express.js is easiest to learn when comparing to other Node frameworks. It provides a wide variety of middlewares for all kinds of purposes.Two reasons why I would choose Express over other Node frameworks:It is very easy to handle middlewares.You can use Node.js native HTTP classes in Express.I recommend you to try Node.js if you like JavaScript. You can skip learning curve of another programming language if you choose Node for your back-end technology.Leave a comment if you have any questions. Share this article if you liked it.

For example, the new website address for the Wordpress site will become www.example.com/blogThe development team instead suggests to move the application to a sub domain instead of the sub-directory and providing links on the Wordpress site redirecting users to the application.My question:Is it possible to make our homepage the MEAN stack landing page without changing the URLs of our Wordpress site url structure and negatively affecting our SEO?If so, how can we accomplish this?

Help with a service that works with 2 databases in Node.js, using Sequelize/Postgres and MongoDB

I've been currently tasked with creating an invoice service, it needs to process/create the invoices in 1 service and process the charges with stripe in another service. I have to count and pair sms with a specific id, total count and then use the ID on those to know who to charge and look for my specific user for the stripe charge.I started my first dev job as a Jr Node Dev, currently on my second month. I'm struggling with some things about this.1.- We have 2 different databases that are going to "interact" for this so I kinda need a way to store the ID of the sms and use them to create the invoice for the specific user and later charge them.2.- In the case of the MongoDB one there's a collection for every new day, so I haven't found a way of specifying the name of the collection when making queries, or multiple ones since I need to create an invoice for the last 15 days.This is the mongo model for the smsMy sequelize model for the invoicesThe file with the status detailsI already have a service for the sms sending part and I think this service could work as a blueprint for the invoice service, obviously changing a few stuff but I'm pretty much lost on how to interact with those 2 databases in an easy way.Any help would be appreciated!

node.js Buffers concat is driving me nuts

Hello reddit,i am currently investigating in a bug that is driving me crazy the whole day. Googling, Stackoverflow, every blog says that the Buffer.concat(list, length) function is there to achieve the appending of all buffers to a single one. But all i get after concatenating multiple buffers is the first one.I am fetching small .wav files from a server and try to append them to a single new buffer and send it over to the frontend. Those files are small 2 seconds samples.On the frontend i want to turn that buffer into an AudioBuffer. Which works, but only plays the first buffer of the buffer list.I use node-fetch for that on the express.js backendfetch(url).then(response => response.buffer());I do that for a number of 1-20 files and store those buffers in an array.I checked every buffer in that array and wrote it to a file on the server. Every single file is playable and unique.But if i do thatlet concatedBuffers = Buffer.concat(allBuffers, totalLength);and write that big buffer ( got the size of all buffers combined, still below 5 MB) to a file, it only represents the first buffer item.I tried to use a library for buffer concat, i even wrote an implementation. But still the same result. Only the first buffer is there after appending.Does someone have a clue and can point out my misleading understanding of Buffers, please?The implementation ( copied from buffer-concat library):function concatenateBuffers( list, length? ){let size = 0;if (!Array.isArray(list)){throw new Error('Usage: concatenateBuffers(list, [length])');}if (list.length === 0){return new Buffer(0);} else if (list.length === 1){return list[0];}if (typeof length !== 'number'){size = 0;for (let i = 0; i < list.length; i++){let buf = list[i];size += buf.length;}console.log('calculated Size: ', size);} else {size = length;}let buffer = new Buffer(size);let pos = 0;for (let i = 0; i < list.length; i++){let buf = list[i];buf.copy(buffer, pos);pos += buf.length;}return buffer;}

How can I debug my Express app and find out why it's hanging?

I'm using Express. When I try to submit a POST request to "/users/new" my app hangs. My guess is that it has something to do with some middleware I'm using, but I'm not sure which one. I have checked all my custom middleware and none of them seem to be the issue.The other middleware I'm using are: cookie-parser, express-session, express-flash, and passport for auth.If you're interested in lending a hand, here's the GitHub repo.Otherwise, how can I debug this? I'm kind of at a loss as to how I might pin the issue down. Registration was working fine before adding passport, but I've checked my config/passport.js meticulously and found no issues.tl;dr - how can I track down what's causing my app to hang?

Making a very small application: Is Electron/NW.js worth it? Can I do ANYTHING else?

Alright, let's face it. Anytime you want to make a node app all you can hear about is electron, nw.js, electron again, did you hear about electron?, YOU SHOULD USE ELECTRON!. And, quite frankly, Electron is a big disappointment. Personally, when I go to make an application I don't plan on making a big application like Discord or Game Dev Tycoon if you're into that stuff. What I'm looking for is something that makes everyone's else's life easier.Before I go into the issues with Electron and the alternatives, let me go into my use case. I want to write a cross-platform Minecraft launcher (please, I don't want to hear any comments like "there's too many" or "why Minecraft" or "that's a kids game" or ANYTHING RELATED. I DO NOT CARE.) I would write it in Java, but I have had issues with that (and quite frankly just don't want to learn it) that I will explain further down. I need this Minecraft Launcher to be able to do a few things: Connect and download files to and from the internet (what can't do this?), modify files on a user's system and be able to launch Java, and have a good-looking interface to compete with others like TechnicLauncher, ATLauncher, and even the Vanilla Launcher itself (the twitch launcher doesn't count :/).With that said, it's time to continue. My biggest disappointment with Electron is, well, these:~ RAM USAGE! Every Electron app I have used (Including VS-CODE) uses a good 200-400 MB of RAM. And that doesn't sound quite bad until you need your application to be able to run on low-end machines. Uh oh! You've run into an issue. Only 4 GB of RAM in 2018? Yes, this is a thing, and it's quite common. More than you'd realise. 4 GB of RAM allows you to, well, run Windows, Discord, maybe Google Chrome and VS Code and then that's pretty much it. Electron is not a good solution, it's a workaround to a better solution. Just going with, "It's fine, everyone can handle it" will result in unexpected results. Downloading a version of chromium and node for every application is ridiculous. Imagine we have 15 different applications we use each using 400 MB of RAM. That's 6 GB, which is going over our 4 GB limit as well as barley matching many machines today (I still see laptops for over 200$ with only 6 GB of RAM). This is unacceptable.~ FILE SIZE! You know what? Call me picky, but this annoys me when others say "oh but 50-100 MB is 0.00000000001% of many HDD's today!" You're right. Disk space is not the issue. It's internet speed. I want my users to be able to download this (reminder, SMALL-USE) application fast! And, as many consider whining, many have internet speeds of unacceptable but unavoidable levels. I know a person who has 512 KBPS download. Why? Because CenturyLink says "fu" to their customers in that area and refuses to sell them anything higher. No Xfinity. No satellite-based ones. That is the only option in their area. So, with 512 KBPS you can expect a good 30-50 minutes waiting for this application to download. 200 MB application because you didn't bother zipping it? Well you'll be here for a good hour and a half. Unacceptable.~ IMPLEMENTATION! Okay, I get it, bundling chromium and node together in one package makes versioning easier for developers and makes it much easier to not have to worry about outdated applications. But is this seriously the best idea? Most machines nowadays have Java installed on them, and nobody actually seems to mind. I see many people online posting "but I don't want to have to install one thing to run this application", and I can see their point. With many different versions of "back-end" helpers, it can be an issue. But you don't see that stopping developers and users from using it. The issue with Java is that it's more used for large scale applications like Minecraft. It's also, ignore my "whining", personally much harder to use.These are my main three issues with Electron. Now, let me talk about some alternatives that I have an issue with:~ NW.js! This is essentially Electron, just made differently. It still has filesize issues and RAM usage issues.~ Electrino! IS dead. Unmaintained. So, I found this in their issues...~ Quark (or whatever it's called, to lazy to check my browsing history rn)! This project seems like it will be the best alternative in this list so far. The roadmap for it looks amazing for how big of a project it is (although we'll see how easy it is for it to go through) and I can't wait for it to come out. Unfortunately, I have already gathered a team and gotten the basics down in Node.js and would like to begin work fairly soon. I have been hyping it up a little.~ node-qt! This one looks amazing, but seems to be completely unmaintained and outdated (last commit (essentially) 6 years ago? wow).~ Yue! Another one that looks amazing and I might end up trying, but I have not heard good things and (I haven't done much research into this one) looks as if it might not have the abilities I need it to. I have not checked file size or RAM usage.~ node-webui (or something like that, had to do with opengl)! This one looks like a good idea but I'm not sure if I want to go full native-level OpenGL.With that out of the way, let me explain why I don't want to go into other languages. Quite frankly, the biggest reason of all is that due to the way I work (and motivation for pastime projects), I lose interest in doing a project quite quickly if I am not able to execute it soon using the knowledge I know about the current language. And, in the end, it boils down to "I don't want to learn another language." Yes, I want to learn C++, C#, and similar but I have had so many issues transferring and getting used to those versus Node.js. Node.js just seems so easy to use, quick to set up, and has everything that I'd need. I don't know, this may just be me having issues learning new languages but here's some reasons why I don't want to learn specific ones:~ Python! I hate the layout. Absolutely hate it. There is no way I will ever try and learn a language that is tab-based. And yes, I've seen projects like python-brackets (if that's even what it's called), but it was very hard to learn for a beginner and in the end I threw my hands up and gave up.~ Java! I'm making a Launcher for Minecraft, why would I not use this? Well, I'd have to learn many different styles and ways to code Java. I'm not new to the language at all, in fact I am trying to get into Minecraft Modding at this point which is helping me learn Gradle. But every GUI library I try and find for it either is extremely difficult to learn or is hard to use/make better looking than a Windows 95 program.~ C++/C#! I actually truly do want to learn these, but I have had the hardest time trying to find tutorials and similar for them. Everything I've tried is difficult to use, or every tutorial I've found ends at simple logging to console and math operations (some get into cmd-user input). I have not found one tutorial that is for beginners, and transforms into GUI.~ Go! I just straight up don't want to learn it. I haven't bothered looking for tutorials but from what I've seen it looks very similar to JavaScript but in a way that makes it look weirder and (imo) stupider to use. And, while I haven't checked, I don't believe it has a huge library of modules.Finally, I just want to state one quick point. I have spent months actually searching, going through pages checked tutorials and articles and trying out other languages, as well as giving many a shot trying to learn a couple even attempting to make programs and stuff out of them. But in the end, none of it was as easy to use, maintainable and readable as Node.js. And everything I've found for Node.js has one of the three listed issues I have with Electron or is outdated, unstable, or unmaintained / not completed. So, as you can see, I really do have my heart set on Node.js.So, in the end, I come to Reddit. I tried Quora, but I am not giving them my real name. I knew I'd just get yelled at on StackOverflow as I have done many times. I don't know how many people will read this (if any), but if you have please, I am begging you, do you know of ANY alternatives to Electron that match the given requirements above. Months of research, searching, and digging have gotten me nowhere. Is there even anything out there that is for Node.js and matches my requirements? If so, is it usable? Maintained? And most importantly, cross-platform?

How to redirect to correct client route after authentication with Passport (react, react-router, express, passport) ?

I'm creating a webapp with NodeJS/Express as the backend and React as the frontend. For authentication I'm using passport-local strategy. I'm following this tutorial to implement it. As in the tutorial he use pug it's easy to redirect the pages as it's done via routing on the server. But as for a react app, routing is done in the client (with react-router) I find it difficult to redirect to a specific page (Component) when the authentication is done. How can I achieve that ? Is there any tutorial that I can follow and get an understanding about this ?

How do I get more involved with my company’s node infrastructure?

So I just graduated and joined as as a frontend engineer to a company that uses a node/react stack. While I love building up features and making our website come to life, I’m also quite interested in nodejs as a backend and how webpack/babel do their magic.I really want to acquire the knowledge that will me get a better understanding of how our web app works behind the scenes so that I can help improve it and maybe one day even help fix things if somethings breaks.However, when I look at our webpack configs and everything to do with how our app is built I feel really lost. There’s just so many files it seems and even though Ive worked with node for some of my personal projects, I feel like i don’t know enough to understand our seemingly complex structure. Even just looking through the scripts in our package.json is confusing for me.There’s only a handful of people in my company it seems that really know how our node infrastructure works and I want to eventually join that club. What’s the best way for me to become more familiar with how larger production node systems work so that I feel more comfortable when being on that side of things? Should I just watch pluralsight tutorials? Read articles? Brute force looking through my company’s repositories? Thanks in advance!

Errors best practices

Hi everyone, what are the best practices for error handling in Node.js?I am building a web app and I am wondering:Should I just use the Native Error class, or should I extend that for every kind of error I want?In a web app I have a lot of different routes and all of them may raise an error. What is the best practice as far as where to deal with these errors? Do I answer a client as soon as I encounter an error, or is it better to next the error until an error middleware?By default the error class accepts just a string message. What about code, Http Status codes etc?Thanks

MEAN stack learning rythm/learning curve?

Hi. I've started with MEAN stack, focusing in node, about 2 months ago. And I feel somehow I'm going slowly?So far in these 2 months I've done/learnt this:-Express (memorized the whole API just for fun).-The basics of node (npm, events, routing...)-The basics of Angular (just binding, modeling, setting up controllers, not much more)-How to setup a a DB and creating models and schemas with Mongoose, validating them, populating, relating collections... and using the database to create different CRUD thingies.-The basics of Oauth and passport (I can make an app that authenticates with FB, twitter, linkedin...).-Some websocket stuff (enough to make simple chatrooms).-How to setup a REST api (never did that before).-How to tinker with EJS in html templates.-Testing with mocha, chai, sinon (in some depth all of them) and now starting with TDD. Learnt most common patterns for testing in different use cases (CRUD, routing, DB queries, models...).-Combining all the above to create basic CRUD sites (users posting posts and threads for example), with Oauth login, data validation, with some frontend logic (with Angular), developed with TDD methodology.Yet I feel like I have impostor syndrome. Currently I'm dedicating 9-10 hours a day to this stack, so I feel I should be more advanced with such dedication.Is this a proper pace for 2 months or should I push harder? how was your learning? What tips or resources could you give me to accelerate my learning?Sorry if this question is not appropriate for this place. Will delete if needed.

Express: Forward custom headers received from client to microservice server

HiI'm developing an an Express server that aggregates data from multiple microservices (by calling multiple APIs) to give client an aggregated response - so that the client does not need to make multiple API calls and that can be handled by the aggregator Express server.Now, the client sends some custom header like for auth, device info (for logging). These headers are processed by the microservices to authenticate requests, do some logging etc. So, the aggregator Express server just needs to pass along these custom headers while making API call to the microservice.My question is what is a good approach to pass received headers to an upstream server. Passing `req.headers` from router to every function right to my apiService (where I put my http request method calls) seems too repititive and dirty in code.Does some global request level context exists in Express, so I can avoid passing the req object around?I know global variables are evil, but passing around req object everywhere also just doesn't feel right.Please share what you feel is rigth to do in this scenario. Also share your experience if you have come across the same problem before.Thanks. Any help is much appreciated!

How to create a monitoring server and display the differences?

Basically, I am creating a server that monitors JSON array outputs from another server and display the differences the next time it gets a new value. The server uses axios to get the "currPoll" with timer setInterval is 10 seconds to get the current value and compare to the previous value (prevPoll).I tried using global variables but I am unable to preserve the previous array to make a comparison to the current array. Can someone point out how do i keep "prevPoll" so I can reuse it to compare with "currPoll" and display the differences every 10 seconds?prevPoll = [ ]; currPoll = [ ]; differences = [ ] ;function getValidPoll() { axios.get('localhost:1050') { .then(function(response){ currPoll = response.data; return currPoll; }).then((currPoll) { for(var i in currPoll) { if(!prevPoll.hasOwnProperty(key) || currPoll[key] !== prevPoll[key]) { differences[key] = currPoll[key]; } } return differences; }).catch(error => { console.log(error); }); }var interval = setInterval(getValidPoll, 10000);

Any Node programmers interested in implementing the blockchain and syncing parts of Ethereum in Node? Similar to Geth and Parity?

One of the main difficulties with Ethereum is the time, effort and resources needed to have a functioning node that has synced the blockchain from other nodes.I'm interested in writing a system that downloads the blockchain from Geth and Parity nodes, using node.js. I want to avoid coding the Ethereum VM in this project, and use an existing implementation, or a somewhat modified one based on Geth or Parity that interfaces with the node part of the system. (Though writing another EVM in C, C++ or Rust appeals to me, that seems more difficult than necessary to start with).I have some ideas regarding data (not chain) sharding that will improve capabilities relative to Geth and Parity at present. I am also considering how the sharing of Ethereum data can be disconnected from validation and running the VM. Blocks of data could be downloaded and made available as torrents, for example, with validation running on data structures that were extracted from downloaded files that contain many blocks at once.

I'm assuming that this is due to the relative path being calculated in a different manner now? if so, how can I set it so that it works both in the project itself and as a module?
