No Frameworks, No NPM | Node v8.x

hi Guys This Udemy Course promotion Today For limited time. I hope you like it. + 15 hours -The Node.js Master Class - No Frameworks, No NPM | Node v8.x(HOT & NEW) -The course is very detailed and shows exactly how to perform many tasks solely with Node.js modules in a simple yet complete way. A perfectly functional login system is made with only a handful of Node native modules, while many tutorials out there try to achieve the same thing with 20+ external modules. Brilliant. Instructor is very quick with Q&A responses. Very friendly. Does a great job of explaining the what and why as you write the code. Based on responses to my and others questions seems to be very knowledgeable on the subject and not just recycling others material. I have found some great courses and this is definitely one of the top ones. https://ift.tt/2vUf8Za

How to Unit test DAO layers in Node in 2018?

I've asked this before, and never got a great answer. I'm hoping things have improved since but I'm not sure...Are there any recommended ways to test the Dao layer of a project? And especially in a way that a) is easily done on a new clean system, and especially on a CI system such as Travis, and b) that allows for each test to be distinct from the others, so there are no data dependencies between tests. However, because I'm using postgres I need some way to get the correct schema set up as well.In the past I've done this in Java using an embeddable database, and then code to empty the tables between tests.What I'm curious about is if there is a good way to do this in node? I'm suspecting the answer will be something including Docker but I'm not sure if there's anything better?Cheers

[Help] Running multiple applications in the same process

If you have two separate applications you want to run on one server, let's say an express webserver and a slack bot, you could execute both of them separately, or you could require them both from a common module and execute that, so that both applications are sharing the same process.I was wondering if it is common to do the latter? I presume doing it that way would let you squeeze a little bit more performance out due to reducing the need for context switching (in a single-core environment), but I imagine that's not too significant.

Any way to automatically copy packages if they are already installed rather than download them

Is there a way for node to be aware of dependancies already downloaded? Like can I set up a folder where all the packages I download keep getting saved to and whenever I run npm install package it first checks if I have that package in my folder and if it is it copies the package from there instead of downloading it?Asking because I have slow internet speed and having to set up multiple react projects takes more time than what I actually spend coding. :D

I'm using "classnew" because when I want to view my pokemon.sql in cmd prompt, I type database classnew; and source pokemon.sql; var home = app.get('/', (req, res) => res.send('Welcome to my Pokemon API. We are using only gen 1 pokemon here! Use localhost:3000/pokemon to view your pokedex!')); var pageOne = app.get('/pokemon', function(req, res){ con.connect(function(err) { if (err) throw err; console.log("Pokedex Connected!"); con.query("SELECT * FROM pokemon", function (err, result) { res.json(result); if (err) throw err; //console.log(result); }); }); }); var info = app.get('/pokemon/:id', function(req, res){ var id = req.params.id; con.query("SELECT * FROM pokemon WHERE id = " + id, function (err, result) { res.json(result); if (err) throw err; console.log(result); }); }); app.listen(3000, () => console.log('Example app listening on port 3000!')) and here is my HTML document that I need to use to submit new info to my SQL database:

Things I like about node

Here are some of the things that I think makes node amazing compared to other languages. If anybody would be so kind, I'd be interested to know why other languages don't have these things... or why these things aren't actually as great as they seem.Local DependenciesInstalling dependencies in an arbitrary system folder seems ridiculous and I don't know why any package manager ever did this. I understand why it sometimes makes sense, but the fact it's the default for other scripting languages like python is ridiculous.No Namespace PollutionIn node, when I require a file, I assign it to a variable. In almost every other language I import a package... then call something of a completely different name. When reading someone elses code I often have no idea where the code for a function call is.Explicit CodeNode, and the majority of popular packages do nothing by default. So my application starts as a blank page, then does only what I tell it to. Compare that to php, where a default server config is doing 1000 things, 990 of which are completely unnecessary and likely introduce vulnerabilities. Or Django, where my code is basically a plugin and the actual application is basically Django which does 1000 things.AsyncCallback hell is a myth. Async is so embedded in node, and works so well.Less is MoreOther languages seem to implement the same solution to simple problems many times. Node doesn't. For example Java has/had many dictionary type objects... half of which are deprecated. Simple things like http, which should be a standard in all languages often aren't... then there's 50 different packages you have to choose from. Node has many options for packages, but the standard libraries cover all the basics really well and don't have multiple versions of the same thing.

So if i install a package globally, for example typescript (nmp install -g typescript), i can just type the command "tsc" and it works. But can i still do this with a package installed locally, or do i have to specify the path like "./node_modules/typescript/bin/tsc" ?

Database Questions

I'm currently working on my first large full stack web project. However, I'm running into a problem where I believe I made some mistakes with how I wanted to store when I was still working things out, and even if my data is small enough that it probably doesn't matter, I'd still like to know how I should be doing things for the future, even if it isn't worth uprooting my problems to fix right now.Currently I'm using MongoDB, but I'm pretty confident that I should have used a relational database. When I'm writing schemas I feel like I'm trying to emulate SQL. I have no previous experience in any database besides mongo, but I'm managing lots of relationships between documents, and my data seems pretty structured overall. Does it sound like I should have gone with a RDBMS? How can I tell this in advance before my future projects?In the mean time, I'm still handling relationships within Mongo. What is the best way to do this. For example, my website consists of teams that consist of 5-10 players. Should I store the team id in the player document? Should I store an array of players in the team document? What are the advantages of doing one vs the other? Are there advantages of doing both?Similar questions, but on a different scale. Every game consists of 10 players, and players have connections to many games. How do I handle these relationships? What is the best way to query for a player's complete game log? I have to store a player's game stats in that game document, but should I cache this information in the player document as well?I hope I provided enough context that questions can be answered. Thanks to anyone who has read this and can help me out.

Questions about node..coming from php

Hey everyone, I just wanted to get some thoughts from developers who are using node more professionaly than myself.I find myself having great difficulty getting around the async situation. I've written a simple app in node, but I find myself using promises frequently. So that I have a string of .then() essentially making things seem syncronous. Is this common? Is this how you handle data in node? Or is it more common(the only other way I see) to create multiple routes to get different data elements and handle most of that via forms and ajax requests on the client side. Example App.get('articledata',function(stuff){dostuff(stuff)}App.get('adData',function(stuff){dostuff(stuff)}Etc etc2. Whenever I look at for support on stackexchange or elsewhere first advice is to npm another module. Is this common practice to have multiple modules for even simple apps.I wrote a blog app but I found myself including Express, body-parser, cookie-parser, JWT mySql, and md5.And from that I have over 1 hundred modules now, mostly from express.Is this normal, or am I doing something wrong? I really don't like seeing a project and 99% of my code not being my code. And it seems like a debug hell if I ever run into a problem. Hundreds of dependencies to look through.

Live streaming. Where to store video and other questions.

I’m trying to set up a live streaming app and I figured out that it would be better to set up a red5 pro server along with the node app since there isn’t a lot of examples of standalone node live streaming apps. Is this the general direction you would take as well or am I just missing something.Let’s say I set up the red5pro server. Where would I put all the video to be served to users that missed the live streams? I first though of cloud providers but I wonder how expensive it would start to get.Context.

Currently trying to differentiate when to use Servers & when to go Serverless.Serverless will scale infinitely, although it has 1 small cost of cold starts but if the site is used regularly then cold start is not needed.Servers are inherently costly. Even if we don't use it to its full potential we need to always choose a higher plan than our current usage.I want to know when can we go full Serverless.Like I have 1 app where the flow is like -User clicks on SignInEmail is sent to the user with Magic LinkAfter Magic Link is clicked, user is logged inUser can then buy a productAfter payment, user can download the productUser can LogoutCan this be done serverless ?Also, which websites would be Serverless & which would need Servers ?

Questions regarding module.exports

Hey guys,when I use module.exports in any of my modules, for example the following code:const mongoose = require('mongoose'); const Grid = require('gridfs-stream'); const database = 'mongodb://127.0.0.1:27017/test'; const connection = mongoose.createConnection(database, null, (err, db) => { if(err) { console.log(`Error occured during connection to the database ${err}`); } else { console.log(`Connected to the database: ${database}`); } }) module.exports = {connection}; I require the shown module in my entry.js-file.When exactly will the above code execute? When requiring it? If I don't require the export in my entry.js, the code won't execute ever, right?Do I need to require all the the dependencies I required in my exported module in my entry.js file? To my understanding I don't, as long as I'm not (in this case mongoose) accessing any of mongooses features, which would require the mongoose package, right?Let's assume I require the module above in another file, for example test.js, would I receive another instance(another connection) to the database or is the instance shared throughout my code?

Web Dev as Partner for Meme Website

Greetings! I hope you are fine and doing good.tl;dr: I am looking for a web developer to partner up with for a meme website which I wanted to get built but never got to since 2 years. You just make website and I do traffic,hosting and domain etc and we share revenue.I started searching for ways on how to earn money online july 2012. I am not sure if it was worth it or not or it would be in the future but it has ruined my student career. After a year I finally got my payment (regrettably and unfortunately) by using a blackhat method. After 4 years of searching for an efficient way of earning (whitehat style) money online I concluded that the best and most effective choice was to do it with a website. In the timespan of those 4 years, I never earned much and whatever I earned was by using fraud methods and was blinded by that money but I'm just making excuses.The best bet was to now make a meme website that could become profitable in my mind, sure it may not be such an easy pie but I was and still am ready to put in time and effort. Like I said I did not earn much and whatever I had earned was just used for food.I had invested and wasted money in facebook page ads which amounted to 500$. Then I looked for 9gag and memecenter clones and soon enough found one. I spent that 500$ on that script and added features and improvements but then suddenly I realized that I had made a big mistake.I knew if i had to make it work, make it big it had to be unique and fresh idea and not some exact copycat crap. I asked for professional developers and the starting price was 1500$. I was bummed on how and where could I gather that much. It was impossible for me but I still managed to collect roughly another 500$ somehow. I went for the cheap guys and someone from reddit scammed me 190$ as upfront payment, then paid 230$ for a basic version which was made up on shitty raw code and the remaining got locked in paypal. You could say I wasted near 1700-1800$ on this thing.Now I dont have any money, only this phone that could go for 150$ max. If I were to start having a job then it will take me 12-15 months to accumulate 1500$ for the website. Or I could find a partner developer for this project and we could share the revenue according to our terms. You just need to make the website, I will handle the rest like traffic,domain, hosting etc.Dont tell me to get a job, I will be getting one in a month or two.Dont tell me to learn programming because I will not have time for it once I start my job.and yeah this is last repost.

Some help / advice on this project structure would be appreciated

Hello all, so I made a simple project that contains an express server and a create-react-app client side.I was wondering what are your thoughts on this structure that I set up. Essentially you open two terminals and run the server and client side separately and develop like that. You could in sense, add a npm script or other misc script (maybe for building?) in the root dir to run both the client and server instead of opening two terminals...but I'm not sure how to do that (sure npm scripts ...) / what is the best way to do that.Most express and React start kits like these put all the server code in one directory and throw the client as one of the many folder. I like to keep server and client separated since they are both different projects. I understand that in the Node / JavaScript world there are many many ways to do things, but I am just wondering what you guys think.I setup the server folder with a very minimal express code so in sense, you could completely delete the code inside the server dir and put in whatever server you want in there, doesn't even have to be Node based I'd guess.Also, any guides on making code for production ready like with Docker, or maybe even a guide on CI/CD tools would be great, I wanna make this project for anyone to have an easy / ready to go full on development and production process. Any guides I should look at, books? Or if anyone wants to help that's fine too! Thanks again: )

saito - a big data blockchain implemented in node.js

We are pleased to announce the release of the Saito whitepaper and technical demo:http://saito.techSaito is a terabyte-level blockchain that can run real blockchain applications on chain, implemented intirely in node! Saito's javascript 'DApps' (not smart contracts) can be anything from email or social networks to payment channels, and other data-heavy web services.On Saito, developers do not need Google-scale hardware to run decentralized services that can outcompete their centralized peers. Saito applications run in browser, the chain provides routing and bandwidth.Demos showcasing how Saito works and what it does are available on our site, along with working code for developers interested in building applications on the network.To our knowledge Saito is the first and only consensus mechanism that is 'economically perfect', that is, not suffering any collective action problems that deter revenue-earning nodes from spending money to support the public network. We welcome feedback on the network and software design.We have lots of documentation on the site and code to hack on on github, please check us out. Oh, and, we are hiring! (org.saito.tech/jobs)

So I have a web app project that was left by another developer I just started picking up on. The project uses node modules, one of which is bootstrap. So the project worked fine previously. but now when I run it the bootstrap does not work(or any of the modules). We have tested it with the previous developers account and it works just fine.Could there be a difference between what the other user has available and what I do outside of the project? And if so how can I find the differences?We are running in centos/RHEL7, the project was built in intellij and is being run with ng from the command line.

I've created the passport js login with Net Ninja, and now I have also tried practicing it for the 2nd time. and then I am trying to render the profile.ejs if you look at the code in profile routes you will be able to see what I'm trying to do.Like if the user is logged in only then the profile.ejs will be rendered otherwise it would be redirected to the login page.But somehow there is some error popping up in the profile.ejs file where I've called in the user from the route in { user: req.user } but it doesn't seem to get any user. the error always comes up as user is not definedI'm really looking forward to this blogsite 'cause as you said after practicing I feel pretty confident that I would be able to complete this on my own.

Node on Windows Server?

I want to create a couple of internal/intranet Node applications on a server we have at work. The server has Windows Server installed on it.Some issues/questions that I have:Node is installed but NPM doesn't work (times out when installing packages -- might be because of the corporate proxy).I can't seem to get my HTTP application to work using server-name:port-number but it'll work when I remote into the server and use localhost:port-number.Do I need to configure IIS at all or should I not worry about using a reverse proxy since this is an internal setup?If I should use IIS... do I have to use iisnode? The reason I ask is because it looks like an abandoned project.I am using Sublime Text and was wondering what was the best way to edit files on the server... I currently have a shared drive on the server where I am storing the app files (so I can view/edit via the sidebar/explorer).

Not sure of search terms...

So, being 100% honest I haven't been able to search much due to not really knowing how to search for this.Basically, I have a 'success' page that is rendered once a user is successfully created. This page is routed to '/register/success'.I don't want this page to be accessible unless it's rendered through the user creation process on '/register'.I realize that sessions could be an answer, however, I don't want the user to have to be logged in for this due to them probably not having a login since they're creating a new user, which itself should only be accessible when not logged in.Are sessions the way to go with this? If not, that kind of stuff can I search up to get this functionality?Thank you!

Developers coming from backend langs (C/C++/C#/Java) who chose Node for a project, why?

I've mostly seen that Node developers come from a frontend background, which makes sense considering the low barrier to entry, but I'd like to hear the perspective of someone who chose Node coming from a backend (I know, vague) background.Also, it doesn't count if you chose Node because you are managing a team of people who are familiar with Node, or something similar.

How do I construct resource URLs on REST API server?

Suppose I have a REST service with controller methods like this (written using a helper for expressJS):@route('/api/v1/users/:id') getUser(id) { return json({ user: getUserFromDatabase(id), friendsUrl: '/api/v1/users/' + id + '/friends' }); } As you can see, the creation of friendsUrl link is hardcoded here.I'm pretty sure this is a bad idea, because my app is large, and I may decide to change my urls, my api version, or something else.What is the state-of-the-art way to construct REST resource URLs on the server? I suppose they should be tied to controller methods, but I'm not sure how to best do it in JS.Any advice is appreciated!

Hopefully I'm posting correctly.I have a Node Js local server and several identical html pages. On every page I save some user data input fields saved simply on a text file. My problem is that if the users refresh the page the data from the previous html page is send again and again saved on the text file. Is there a way to prevent this?var fs = require('fs'); const log=require('simple-node-logger').createSimpleLogger(); var express = require('express'); var bodyParser = require('body-parser'); var app = express();app.use(bodyParser.json()); app.use(bodyParser.urlencoded({ extended: false })); var port = process.env.PORT || 8000;app.use(express.static(dirname + '/server')); app.use(express.static(dirname + "/public")); app.use('/images', express.static(__dirname +'/images'));app.listen(port, function(){ console.log('server is running on ' + port); });app.get('/', function(req, res){ res.sendfile('intro.html'); });app.post('/userID', function(req, res){ //save the userID on a text file var userID= req.body.userID + ';'; var data = fs.appendFileSync('temporary/userID.txt', userID, 'utf8');return res.sendfile('main.html'); });app.post('/submit', function(req, res){res.sendfile('main2.html'); }); Furthermore, I have also a refresh button that does the same as the browser refresh button.

Custom response with aync/await error handling wrapper inside route contollers?

Hello, I wanted to use async/await instead of simple callbacks in my ExpressJS route controllers, and I have error handling wrapper function that wraps async functions to prevent try/catch blocks all the time but I stumbled upon a problems with it.I cannot send custom responses from it? For example I want control what the controller will respond back, also there might be additional logic inside where I want to send custom error messages, like having conditions that can send back different responses, but using this async error wrapper I can only get the generic error (or the custom errors I set up in mongoose models, but I want to have more options in controllers anyway) or as a response I can only get thing which for example MongoDB gives back from "findOne" method.What if I want to find a record in DB and beside record I want to add more things to the response, I can't find a way to do it with async/await. I just await on result and pass it as res.send(result), no flexibility.I am sure there is a solution to this and would like to hear your opinions. :) Thanks!

Passport.js - using Google for authentication: do I have to use the refresh/access token?

My goal is to have a website where people can login using their Google account. I only extract some basic info such as their Google id, name and e-mail and save it in in a database. My plan is to re-use the record saved on my database whenever they sign in again with their Google account.At this moment, I have setup some code using Passport.js where users can login using their Google account and a callback method gets executed which contains the refresh token and access token and their profile data.If I understand correctly, I will only need the access token and refresh token if I actually call some other Google API. Is this correct?Since I don't want to do that, my plan is to save the access token in a database and save it as well on the client's side to be able to see whether they are authenticated.

[Suggestions] Create and manage Google Form through NodeJS app

My use-case is the following: Desktop app using Electron and React; The user may create a Google Form through the app, possibly through my own crafted interface, or displaying the webview inside the app, with limited controls (I would like to avoid having to open a web page if possible). Said form is then sent by email to contacts, and the app periodically checks for new submissions to display them in the dashboard.However Google Form is rather convoluted on this point. For starters there doesn't seem to be an API for this unless you go through AppScript, and as of now I'm very unclear about what I can and cannot do with it.What I'm looking for mostly is pointers; The online form doesn't necessarily need to be Google's, as I'm rather put off by the lack of a proper JS API. It does need to come without limitations however, as this is meant as a free app.Any and all suggestions are welcome. Thank you.

How to Avoid Requiring the Same Module Multiple Times?

I have several .js files I export and require as modules, in order to separate functionality. For example, I have two files that use web requests:- checkForUpdates.js- getRemoteData.jsSince both files need web requests, they both use:const request = require('request-promise'); However, since const can only be modified once, this creates an error. I could change const to var, and I assume the first require will be cached and used, but I am not sure this is the case or if this is the appropriate way to use require for multiple modules that require the same module. On the other hand, I could require this library before requiring both modules, but then these modules are not able to be used easily in another project and loses context of scope.How should this be handled?Additionally, if there are detailed codebase management guides, please point me to them!

I am making an API which will take JSON as an input via PUT/POST and I want to ensure a few things like certain fields need to exist, certain fields need to be numbers, certain fields can be optional etc.I found a koa-validator but it's not had any change in 2 years on github and seems not to be popular enough for me to trust enough in my production level koa API.How would you guys approach this? I could do it all vanilla but I feel like this is an issue a lot of devs have probably run into and therefore there's probably a better way.Thanks

Observables in Node.js (Express mostly) context

I get why Observables (rxjs) are popular, I can see their pros. But while I can see the use case on front-end what would be the typical use cases for REST API written in Express? I guess I'm a little confused as to their place.Any examples where they would fit nicely and be a legit upgrade (either performance, maintenance or developer experience)?

Have you had experience with any of those and can recommend which one to use or to avoid?

Any Good Examples of Sequelize Data Model with unlimited Tree Structure foUser Relationships?

TL;DR – Trying to create tree structure user relationships with single parent, unlimited children, unlimited levels of depth in which we can pull organizational stats from any user node and their children in scalable way.My challenge is to create a user table(s) with a tree relationship structure. Here’s my outcome, which at first glance seems straightforward.Each user node can have only one parent, as a user must be invited by an existing user.Each user node can have multiple children user nodes. We could limit it to be practical, to zero to 500 children per user.There are no limitations to the depth of relationships. Theoretically, a user could add a user, which adds a user, and this could repeat a few hundred times.This would all be fine, except the primary purpose is for reporting on productivity stats organizationally, so a traditional parent/child relationship would result in exponentially long reads for aggregate data for any given branch.Let’s say we have an Action table like the following:(pk) actionId (Int)(fk) userId (User)createdAt (DateTime)actionType (Enum)minutesActive (Int)We would want to be able to show the user a dashboard showing:Bar graph showing total # of minutes worked each day for a specified action type, mapped over the last week.Same stat showing weekly totals mapped over the quarter.Again, that’s no problem for that specific user, but we also want each user to be able to see aggregated stats for each child branch. Let’s say the first user they added has then added users themselves and so on to where that first branch includes 250 users. Then their second branch includes 150, the third 100, and so on for 20 different branches, and we want their dashboard to be able to show Action statistics mapped over time per branch.At the same time, any other user of the system could be pulling up a dashboard of their branches.This would implode on itself pretty quickly when a single query requires a few thousand read operations.I’ve been trying to study up on the best way to structure user relationships for such a use case, and I’m not finding great examples. It’s challenging when there aren’t clearly defined tiers/levels.I have a few crazy ideas on approaches, but I thought it might save a ton of headache leaning on someone much more experienced.If it matters, my backend stack is node.js/express.js for server/business logic, sequelize.js/postgresql for ORM/DB, Apollo-server / graphql for API, and then my frontend go-to is react.js, using Apollo-Client for async – so all javascript based. I’ve got more experience with Django/Python/Graphene backend, but since I’m so buried in Javascript for frontend anyway, I figured now’s a good time to start doing everything in one language.So, if you’ve read this far, I’m SUPER grateful. I wasn’t sure the best way to communicate my challenge. If you’ve got a learning resource you’d recommend, I’m happy to dig deep on it and do my homework. If you have a solution in mind you could explain, I would love that as well. If it’s asinine to endeavor to achieve this without google/facebook-level resources, I get that too.Any insight would be much appreciated!

Is Node/Express Good Solution for Responsive E-Commerce Portal Using RestfulAPI (Backend)

Hi All,We are planning to develop our E-Commerce Portal utilizing RESTful Web Services API (as Backend) and looking for the following functionality.Develop a Responsive (for Mobile, iPad and Computer) E-Commerce Portal for customers to create/view their Quotes, Orders, Invoices, Inventory etc. and also view/email the PDF documents. We are planning to host the PDF documents on the web server due to size of the documents and therefore need some kind of Server Technology to binary stream the PDF documents on the fly from web server to user’s browser.Develop Handheld Specific Applications to be running on the Windows Mobile (Motorola Hand Held)At this time we are evaluating the following technologies, for our web front-end development:Node.js / Express Web Server (all business logic resides in RESTful Web Services already developed using Java)PHP Framework & (Apache or Nginx) Web ServerJSP & (Tomcat or Jetty) ServerAs all backend business logic will resides in RESTful API's already developed therefore we don’t want any heavy lifting server technology to use.If anyone can share their experience developing E-Commerce / Mobile App using any of the technologies above will really be helpful. Our first preference is Node/Express but just want to make sure it's capable to handle our above requirements.

Is it worth it to use Swagger for our backend?

The company I work for is rewriting our code base from a Django based backend to a node express based backend. Currently we have a Swagger spec written up detailing all of the routes, originally only used for documentation purposes. However, I saw that you can use Swagger for the node backend, for example swagger-node. I was wondering is it worth it? Is it secure? The pros is that we could get a lot more work done faster, thus cheaper, but I am wanting to know if there is any major cons to going this route?

Fastest development, clear maintability, best perfomance, clear documentation.Rules: REST api or MVC for web server. Ignore fullstack frameworks. Version 1 or above.For now i tried (ordered from most to least): - Browsing "Best Node.js web server frameworks in 2018" with nr. of mentioned results: express, koa, sails, hapi, totaljs, actionhero, loopback, adonis , restify. - Nr. of downloads on npm last week: express, hapi, koa, restify, loopback, sails, totaljs, adonis, actionhero.Summary: - totaljs, adonis and actionhero have all under 5000 downloads per week. (others have above 20.000) - Sails and Loopback is built from Express...so perfomance will be in anycase same or slower than with Express. - Koa is (sorta) modular version of Express.
