What's the perfect architecture for a Node.js application using Express.js and GraphQL?

I've made an application using Express.js and GraphQL, but I was thinking of refactoring it, because I just put most of the backend code in a file called server.js. I am wondering if there's any good example on Github that shows you how I should refactor it.

Why I don't use koa ?

1. Wrong middleware modelNormally middlewares should be linear, but koa is stacked.koa also introduced the side effect that every express middleware be rewrite due to its fault.2. Wrong encapsulationNormally if client programmers can easily send the final response, middlewares will have no chance to change the body or get the body.but koa processes the final body passed by the middlewares through the ctx object,every middleware can get the final processed body and modify it,which introduces a very severe security problem.This means every middleware can steal the final processed content and further more change it with out notice.The following link is an example showing where koa is wrong and why it is insecure in Chinese.https://www.youtube.com/watch?v=nofVl7eoSz4

So how fast is Node with Mongo actually?

I'm wondering where are the bottlenecks and what kind of response time can we expect from talking to a MongoDB over a Node.js server.The thing is, I was quite mind blown by the single-query response times from the front-end to the backend-into the DB and back to the frontend. It's literally milliseconds, and that just blows my mind.That being the main idea, I understand how the Event Loop works and that if you write async calls in your server-DB interface, you should have a pretty stress free operation. Including optimizing your queries with .lean() and a strictly typed model structure when does Mongo start to lag? With thousands of concurrent DB queries, memory and CPU start to bottleneck, but at what point does that happen? What about the server? What kind of numbers start to take a toll on the server? I take it, it takes more to slow down the server than it does the database.Just thinking about things, preparing for scenarios where production apps get more traffic or a sudden spike. If you want to boast a little you can share your experience of how you tackled such events with this environment. Keep it simple, though. I love a good challenge. JavaScript rocks and I am so glad to be ridden of the former web-server infrastructure. Apache,nginx, bleeeeh...

GTTS (Google Text-to-Speech) file won't download after deployment

I've tried several different methods with no luck. I posted in a thread that was posted on how to use the package, but it was from too far back to get a response. Here it is, again. $10 tip to anyone who can help with this. Neither the example provided on the github nor the example from the uploader resolve the issue.The file downloads every time, when I use localhost:3000. The file goes into my project directly, even when I specify a path to a different folder. I've deployed to two different places to resolve the issue, and it works on neither (but for different reasons)." I even redid the app with html (rather than ejs) and deployed to github (405 error). When I'm hosting it, the file downloads just as it should. When I do it via Heroku, it goes through the process as if it's working, and redirects to home (which only happens after it's successful), but no file. In the video, no download directory is given, and I read the docs and couldn't figure out how to get that to work. You're supposed to be able to use .save to specify the path and filename, I tried it many different ways and each one failed. The best I got was instead of silently download, it actually popped up in the download history. Normally, it just pops into my main directory, but this time it downloaded like any other file would in my download history, but not so when I re-deployed to Heroku.If anyone has any idea on how to specify the directory or get a prompt asking the user where to download the file, I'd be grateful. https://codeshare.io/2pVPvD (I removed res.download..made no difference, added fs and path to try out several solution that didn't work)Here it is live: https://phrasebooktts.herokuapp.com/Docs:"save(savefile) Do the TTS API request and write result to file.

When I log into my app, I set req.session.user by doing req.session.user = sessionUser;. In the same function, I log req.session.user and it shows the session user. However, when I do another GET request to a test path, router.get("", (req, res) => { res.send(req.session.user); }); req.session.user is undefined? req.session exists, and so does req.session.id.

I would like the Webapp to only be reachable within an IFrame.I want to restrict access to the Webapp because I cannot secure it directly. I can only secure its parent (the owner of the iframe).I don't really know how I could achive this behaviour. I wonder if I could put express in front of the iframe. If the request is authorized I could forward it to the IFrame. Is something like that possible?Or do you have any other suggestions?

When you define a function in NodeJS, which object is that function a member of?

In the browsers execution environment when you define a function, that function is a member of the windowobject. For example:function myFunc() { console.log( 'hello' ); } console.log( window.myFunc ); // valid In NodeJS, we don't have a window object, be we do have a global and a module object. However, when you define a function the same way in the NodeJS execution environment, this function is not part of global object or the module object.function myFunc() { console.log( 'hello' ); } console.log( global.myFunc ); // undefined console.log( module.myFunc ); // undefined So which object is myFunc a member of?

Why would one use nanoexpress over just uWebSockets.js?

So I've been learning to work with regular express.js, which I've found to be more than fine for most things, however I've started looking into faster alternatives because I wanted to attempt to build a simple game server that I want to be performant even on minimal resources.My search brought me to uwebsockets.js, and then nanoexpress. So here's where I'm confused, even though uwebsockets.js has this description "Think of it as a complete replacement to both Express.js and Socket.IO, written entirely in C/C++ for maximum performance and reliability", we also have nanoexpress which is a "nano-framework powered by uwebsockets.js".So I'm wondering why anyone one would want this "thin layer" (nanoexpress) over just using uwebsockets.js if uwebsockets.js is already "a complete replacement to express.js".

What would be the correct database and data architecture to use?Example: - I have a 100K recipes, each having 10+ ingredients - As a user, I can various ingredients (salt, pepper, pasta, etc) in my profile as I always have them. - the application should list recipes based on my set of ingredient - the application should also ‘recommend’ ingredients that ingredient would help increase the number of recipes to the user. For example, if I don’t have salt, the the app may list 10 out of 100,000 recipes. As such, it should recommend a few ingredients that would increase the list - the use may also want to see and research if he should add some ingredient to his shopping list by seeing how many additional recipes would be possible by this ingredient plus his existing ones. For example by searching ‘ground chicken’, plus his profile list of 20 ingredients, the system should list all recipes which are possible to cook

Looking for proper examples.

Hello guys,I am starting a new project and I decided to use KoaJS with TypeScript. Right now I am in the process of setting everything up and I am kinda confused by the lack of good practice examples for my usecase. Anyone got any advice for me? I am trying to add InversifyJS to be able to use dependency injection but I fail at something simple like splitting my routes into different files.

Questions about Micro services

Hey everyone!Currently working on a project for a client, currently at about 2k active users!The current code base is massive, all stuffed into one application that we want to split apart.I get the concept of building each service based on a feature or critical point... but how do you tie everything together and serve content to the actual user?Do you have one a large application that handles basically checking credentials, that then passes it off to the micro service internally?Would love your thoughts and experiences with deploying and building something like this.

Parsing array sent through express' bodyparser middleware using sequelize, express, axios and react redux

I'm having some trouble sending any array from my redux's store as form data. My back-end works using Postman to send an array, I guess I'm just having some problems connecting my front-end to it. My front-end code basically uses form input to update local state, which ideally gets sent in. This is my code below.client/src/actions/customersAction.js// Post New Customer export const postCustomer = newTable => dispatch => { axios .post("/customers", newTable) .then(res => { dispatch({ type: POST_NEW_CUSTOMERS, payload: res.data }); }) .catch(err => { alert(err.message); }); }; server/routes/customers.js // Post new customer app.post("/customers", (req, res) => { const { newTable } = req.body; const { customer_name, customer_phone } = newTable; // POST single customer if (newTable.length < 1) { db.Customers.create({ customer_name, customer_phone }) .then(customer => { console.log("> New Customer Created"); console.log(JSON.stringify(customer)); }) .catch(err => { console.log(err.message); }); } // POST more than one customer else { db.Customers.bulkCreate(newTable) .then(customers => { res.json(customers); }) .then( () =>{ console.log('> Multiple customers created.') }) .catch(err => { console.log(err.message); }); } }); /server.js (partial-code)const app = express(); const PORT = process.env.PORT || 5000; const db = require("./server/config/database"); const router = require("./server/routes/index"); app.use(express.urlencoded({ extended: true })); app.use(express.json()); app.use(cors()); app.use((req, res, next) => { res.header("Content-Type", "application/json"); next(); }); Postman example that works{ "newTable":[ { "customer_name":"name", "customer_phone":"1111111111" } ] }

Advice on mern authentication application

I am building a full stack application using the mern stack. This application is required to allow users to register and login and once they are logged in the users should be able to view and add information to their profile only. My backend is working great and i am using jwt to check who is logged in and then that allows me to post as that user only which is great.In my front end though i am able to login and sign up as specific users and it connects to the backend well, the only issue/question i am having here is when the users login they should be able to create their own car data so every car will have their own user assigned to it( in my backend i connected both user and car schema well and every car has an id) that is how i know who owns what car.My question is i want to fetch all the cars from the database and display them ( thinking this would work well but have not done it this way) vs having an additional localstorage item which then contains the token of the logged in user and another one that will contain the logged in users newly created cars ( this request gets sent to the back end either way and creates a new car from my backend end point ) i am using local storage here to keep track of the current users cars.What is the best way i can link the current users newly created car because right now local storages like a good approach.Thank you in advance

Does sequelize transaction locking prevent a row from being accessed at all?

So let's say I have a user table tied to a media storage table. Every time a user uploads a video I want their user id to be attached to a row in the media table. Also say that it takes an arbitrarily long amount of time to remove a user. Lets say 15s for examples sake. If a user hits upload at 5s of the 15s run and the server has already started the process to remove the user, will a query to see if the user exists still be true? Does transaction locking apply to the whole table?The same for creating a user. Let's say I create a test to run 2 user creations in parallel and by some fluke the test generates the same username for both (assuming it should be unique). While I can place a check in the create user route to see if a user with that username already exists, 2 calls running close enough would both return true. Yes, I can add a constraint to the table to prevent non-unique usernames, but I'd much rather throw my own error, than let the call get all the way to the database before throwing an error.Is there a way to "lock" the whole user db table so when a user transaction is happening any call to the table must wait for it to finish?OR am I thinking of locks and transactions completely wrong?I was thinking of using a status column as I know sequelize allows for row locks, but I wasn't sure about the situation described above.

Node and AWS Lambda Help

I'm trying to use AWS Lambda and Node to write items to a DynamoDB table. I can hard-code the values I want to see with no problem but I can't quite figure out how to see anything when I'm writing to my front-end which is in React. But I get a 200 success message when looking at the network.I broadly adapted from this tutorial.Here's my function in Lambda:​const AWS = require('aws-sdk'); const docClient = new AWS.DynamoDB.DocumentClient({region: "us-east-1"}); exports.handler = (event, context, callback) => { console.log("Processing..."); const params = { Item: { Corpus_Name: [], Source_Name: [] }, TableName: "corpusTest" }; const response = { statusCode: 200, headers: { 'Access-Control-Allow-Origin': '*', 'Access-Control-Allow-Credentials': true, }, body: JSON.stringify('Item Added'), }; docClient.put(params, function(err, data) { if(err){ callback(err, null); } else { callback(null, data); } }) }; With the const Params I can hard code whatever I want but I can't figure out what to put to tell it to actually take in what I type in my web-form.Here's my form.js in React:​import React, { Component } from 'react'; import axios from 'axios'; export default class Form extends Component { constructor(props) { super(props); this.state = { Corpus_Name: '', Source_Name: '', }; this.handleSubmit = this.handleSubmit.bind(this); this.handleCorpusChange = this.handleCorpusChange.bind(this); this.handleSourceChange = this.handleSourceChange.bind(this); } handleCorpusChange = (event) => { this.setState({ Corpus_Name: event.target.value }); } handleSourceChange = (event) => { this.setState({ Source_Name: event.target.value }); } async handleSubmit(event) { event.preventDefault(); const { Corpus_Name, Source_Name } = this.state; await axios.post( 'https://15ix4rukfb.execute-api.us-east-1.amazonaws.com/default/serverlessAppFunction', { key1: `${Corpus_Name}, key2: ${Source_Name}` } ); } render() { return (

Corpus_Name: Source_Name:

`npm update ` does not update package as expected--any ideas why?

Hi all. If I run 'npm outdated', it indicates one of my node packages (stylelint) is outdated--I have version 11.1.1 and the latest version is 12.0.1. When I run the command npm update stylelint, there is no change--I seem to still have version 11.1.1 installed (screenshot). Any ideas why that is occurring? There is no output in the console.My package.json file for the project contains: "devDependencies": { "stylelint": "^11.1.1", } Doesn't that mean the package should update to any version greater than 11.1.1?Maybe the issue has something to do with this being a major update (i.e. from v11.x to v12.0)?Just prior to this, I was able to update some other outdated npm packages in the same project, using the same processThanks in advance.

Websocket doubts

Hi! I'm getting deeper in websockets and in my research I found this:- websocket is a standard now with full browser support, so we can just use ws and let our clients connect with native API for websocket.Pros:* Plain native solution* Clients could use a lot of alternative libsCons:* We have to write our own boilerplate code in order to get a full solution with reconnect, disconnect detection, rooms, heartbeat, in server and each client. This is even suggested in ws documentation.- Socket.io is a battle tested socket solutionPros:* Oficial client for Java, Swift, etc.* A lot of plugins, docs and community.* Support all the weird scenarios: load balancers, proxies, etc.Cons:* Adds delay on initial connection because a custom protocol (polling and upgrade to websockets)* A little unmantained (a lot of unresolved issues and last publish 3 months ago)- Sockjs is a very very popular socket solution, I could not understand why.Pros:* Support all the weird scenarios: load balancers, proxies, etc.Cons:* Without oficial client for Java, Swift, etc.Questions+ Could you tell me if I'm wrong or I'm missing something?+ Why sockjs is getting more installs than socketio when sockjs doesn't have Java/Swift clients? How could you use sockjs if you can't use it in your mobile apps? Even in hybrids apps you have to write/use native code/modules in order to have a background service.* Why ws is getting more installs than every body when you have to write your own boilerplate for each one (server, web, android, ios)?Here the comparision

Other than REST and GraphQL, what do you guys use?

I'm building a web app and REST and GraphQL seem to be overkill for what I want to achieve. All I want is to get data for my React front-end and do couple of HTTP POSTs.I'm thinking of simply creating express routes and using JSON but it seems cumbersome. Or is that a common practice?I'm wondering what the alternatives to REST and GraphQL are.Curious to know what y'all use for simple web apps.

Correct way to unit test Express middleware feat. Dynamoose?

I'm working on an Express application which uses Dynamoose within its middleware to save items into DynamoDB. I have a module which exports a function to do the heavy lifting; it validates the input, transforms it a little into a different format and then saves the transformation into the database.Database interactions are done using three, non-exported, helper functions within the same module: saveModel, getModel and updateModel.Ideally, I don't want to spin up a testing database while the tests are running. I would like to stub out the three aforementioned functions to mock database interactions and control the information that is sent to and from the stubbed functions in my tests.I've tried using SinonJS to create the stubs, but I think there's a scoping issue as the functions aren't exported. I'm using Jest to do my assertions.Does anyone know some good practices or tools to use? Perhaps I need to change my middleware function into an ES6 class to expose the three functions, and reference them in the (previously exported) main function via this.FUNCTION?Completely lost in this. Any help would be amazing.

Accessing a Windows share drive (from Linux) in node.js?

Hi folks,I'm trying to access a Windows share drive from a Cloud Foundry deployed node app on a Linux stack (cflinux2). From what I have pieced together to do this requires the samba protocol.I've messed around with samba-client but can't get it to work because the Linux stack doesn't have smbclient installed. Not sure if I can somehow configure that through Cloud Foundry somehow?Ok cool whatever, I'll try smb2! Echhh, top of the description says it shouldn't be considered production ready and I'm not able to quickly access at work because its dependency is missing a license, makes our legal team sad :-)So what can I do: * Deploy using a Windows server - nope, sadly my company is unable to do this, it would be a fix though * Develop my own samba protocol implementation on node - holy smokes please no, I just want some files on a drive my man * Use some other approach I don't yet know about..?So any thoughts on how I can do this? It's driving me a little crazy, especially because I was trying to make a very lightweight node app to replace an ugly as hell spring boot behemoth but now I'm finding there isn't great package support for this process.Apologies if I have a butchered understanding of things, I hadn't the faintest clue about Windows share drives and samba a day ago!

All Node.js Frameworks Suck Compared to Rails

When it comes to Developer Experience and speed of iteration, all node.js suck in comparison to Ruby on Rails.I wish the node.js community would stop creating new and shiny frameworks every month and devote the focus, time, and energy on a single framework. Every framework from express, koa, next, sails, Adonis, meteor, nest, hapi, loopback, etc, blah, etc, blah has a certain flaw or weakness and all are not as great as rails as a comprehensive framework that just lets you get things done.It’s time for the community to stop creating new node.js frameworks and double down on a set of frameworks like the php, ruby, and python community has.

Trying to understand AdminFS

I already have this setup in other areas and through poking and prodding I've gotten it to work in those areas, but I still don't understand what is going wrong. I am hoping someone can explain it to me. Here is the Firebase Admin Firestore code: -async function that is also middleware- let user; await adminFS.collection('users').doc(req.body.uid).get().then(doc => { if (!doc.exists) console.log('User not found.'); else { try{ user = { uid: doc.uid, email: doc.email, displayName: doc.displayName, subscriptionLevel: doc.subscriptionLevel, subscriptionID: doc.subscriptionID, admin: doc.admin, token: doc.token } console.log(doc); console.log(user); } catch (err){ console.log(err, err.stack) } } console.log(user); }); console.log(user) So, console.log(doc) will give me all the information I need but also information I don't need but if I use something like token.uid it will be undefined. The first console.log(user) will result in nothing even though (in my mind) user should have been just defined. Even after the if statement has completed, the user is still undefined. Even after using Async and Await, which should force it to be sequential, user is still undefined.

Unable to redirect after using XMLHttpRequest.send()

Hello, I've recently been hitting my head on a wall over what feels like a simple problem.In the past, I was using simple post forms, but since then, a few things changed, and instead of using a form, I ended up using multiple input fields, with a submission button that uses XMLHttpRequest.send()When it was a simple form, the backend itself was able to redirect with a simple res.redirect, but since changing over to this new posting method, I've not been able to do so.Not only that, but if I bypass this problem by redirecting in the client-side js, it stops the back-end from finishing its task (Login/Registration.)The chunk of code I've been using to send the details is this:xhr.open("POST", '/user/login', true); xhr.setRequestHeader("Content-Type", "application/json;charset=UTF-8"); xhr.send(JSON.stringify(userDetails));

Any database-agnostic, high-level abstraction layers that can handle MongoDB, Redis, Elasticsearch, and Postgres?

I'm creating a web API. I'd like to be able to do most of the prototyping in Mongo, and switch to Postgres for prod. With Redis for caching and Elasticsearch as the search engine.Atm, I'm just using the MongoDB driver directly for prototyping; the data that I'm handling doesn't have any sort of fixed schema. I'd like to switch this out for some sort of abstraction layer. Ideally, I could write all of my db queries for Mongo, and simply switch out the Mongo adapter for Postgres, Redis, and ES adapters as needed.I've used Sails before, so my first thought was to use Waterline as a standalone module (which I've never done before). Any other recommendations?

Moving from Babel ES modules to pure Node.js 13.2

As of Node.js 13.2, ES modules are supported without a flag. I have a large project that supports ES module syntax with babel, and now I'd like to remove babel if possible. However, this doesn't seem to be as simple as adding "type": "module" to my package.json and ripping out babel.For one, none of my import statements include .js on the end. Most look like import Thing from './thing' to import the default export from the thing.js file. The Node implementation of ES modules seems to require the .js on the end (I get a Cannot find module... error without it). I'd love to not have to go around renaming every one of my imports to end with .js.I also have tons of modules organized as folders with an index.js in them which controls the public interface of the module. Every usage of this imports only the folder name (import Thing2, { otherThing } from './thing2 imports the default export from ./thing2/index.js). This also seems to give me a Cannot find module... error, and again, I'd like to not go change everything to import from ./thing2/index.js.Is what I'm doing not actually ES module spec compliant and just some extra Babel sugar? Is support for this in Node still forthcoming? Having trouble finding documentation to explain how/if Node is supposed to ever handle these two examples.

Is there a way to make Bcrypt (or a similarly secure hashing library) output hashes with a length under 40 characters?My intention is to use Bcrypt to hash a user ID so that it can be used as a password for a third party service that only accepts email+password logins. However, the service only accepts passwords with length of 40 characters or less.How could I accommodate this restriction while still keeping passwords secure.​FYI, the user ID and output password will be visible to the user.

Beta testing of ~15k lines of codebase written mostly in node.js

HI!https://dmt-system.com https://github.com/uniqpath/info https://dmt-system.com/slides/dmt-player.pdfLooking for beta testers (all information that I can provide at the moment is in these three links) and then over email individually (write to info@uniqpath.com if you want to test). Testing is 100% safe because you can test on an offline RaspberryPi if you wish -- or, even better, you can check the source code for any missteps (there are none) when you receive it. You basically would have to only check for any filesystem wrongdoing or outside sending of information. It's easy to check for both. Code is going to land on GitHub on the release date (without the IoT part for now).This project is coming "out of the blue" and it's a bit tricky for people to take a leap of faith. Nevertheless we got quite some testers already but we are looking for more because there are different aspects of the system to test.Just as a fun trivia: I smoked a joint with Ryan D. a year before he invented node.js :) I'm not sure if it helped him but it sure helped me. I saw how to think outside of the box by listening to him and later observing what happened.Thank you! david

Sharing DB connection in GraphQL

I’m re-writing a terrible hand rolled di injection container at work to share our aws-sdk client, amongst other things. We’re using GraphQL so I first thought, why not put it in Context? The further I got, I found services being instanced above resolver scope with access to Context, so then I moved it up to instanciating in a function that creates the schema. But then, I had another idea.. why am I doing this at all? Can’t I just do:// dB.js export default createConnection(); // service.js import dB from dB Create an effectively singleton instance, then import where needed? It looks perfectly testable and massively more convenient than passing through function calls. Is this actually a bad idea for any reason?

How do I set up google polymer 3 in express.js?

How do I set up google polymer 3 in express.js? I've never used polymer before, and I can't seem to get a hello world app to work. I've spent 2 days googling this, and it sounds like polymer 3 is setup much different from the past versions. I'm only finding tutorials and documentation and tutorials for the past 2 versions. I've seen versions that work for angular, but would like to avoid using angular, and would rather use express to build my webpages. I can use typescript if needed. It seems the issue is, polymer doesn't put a / in front of it's directory's in the module, and the module scripts are not public. I've heard of bower install, but there npm suggests I use something else for polymer. Can someone educate me on what I should to do?

Does my app get bigger when I split my code to many files and I import modules in every file I use?

Hello!I have started learning NodeJS and I'm doing my experiments and developing a habit of splitting my code to many many files so that I when I have to change something I will do it only on a particular file and avoid too many lines of code, let me give you an example: routers.My web app has routers and one of them is called /about_us which is a parent and has the following children:/about_us/team/about_us/members/:id/about_us/mission/about_us/locationAnd each of them I have them split in multiple files.about_us_mainRouter.jsabout_us (folder)team.jsmembers.jsmissionlocationand there are times when I want to make some specific changes, for example, members I change only the members file.My router code is like this:about_us_mainRouter.js const express = require('express'), aboutUs = express(), members = require('./about_us/members'), mission = require('./about_us/mission'), location = require('./about_us/location'); aboutUs .use('/members', members) .use('/mission', mission) .use('/location', location); module.exports = aboutUs; and a file which gets imported is like this:members.jsconst express = require('express'), members = express.Router(), membersController = require('/controllers/about_me/members'); members.route('/:memberId') .get(membersController.retrieve) module.exports = members; As you can see in every router, I import express and express Routers and I've been wondering:Does my app, loads express() or express.Router() for every import I do? If I have for example imported express 100 times (if I have 100 Routers) does JavaScript/NodeJS load the module 100 times?Is there any way of skipping the imports, since I have imported them in other files, and making my code shorter even more?Thanks

My Sequelize Tutorial

Hey everyone! I was looking for a community to post this into and found r/node. If this isn't an appropriate post for the subreddit, please let me know! I picked r/node because there isn't a Sequelize subreddit and Sequelize required Node.I built a tutorial revolving around using Sequelize, primarily for beginners, and would like some feedback on my tutorial. I've asked colleagues and friends for feedback, and so far it has been positive. I'm looking for a wider audience to give me feedback, since I want to make my tutorial the best it can be. I've put a lot of effort into writing this and am looking for constructive criticism. Before submitting feedback, please understand it is still a work in progress! A lot of Sequelize functionality is still missing from it, such as deleting information from a table, deleting data from associations, many to many associations, and so on.https://github.com/rlorenzini/mySequelizeTutorialA little background for those who are curious. I am a new developer (just over 1 year of coding experience) who went through a bootcamp in Houston. Once I graduated, I became a teacher's assistant. When we started covering the backend (Node.js, Express, pg-promise, Sequelize, postgreSQL, and more) a lot of students were struggling with Sequelize. Personally, I love Sequelize. I never liked creating a bunch of functions to run pg-promise commands when there was a library which already did that for me. I also struggled to grasp pg-promise at the time, so I gravitated to Sequelize.When I asked some students, they told me the documentation was confusing and difficult to follow. The Sequelize documentation is extensive with literally everything, but I never go there because it is written so poorly. I always went to alternate websites or medium articles to get help with Sequelize. One student specifically said, "Why is there no good single source for Sequelize?" It dawned on me I could be the one to make such a thing. Thus, my tutorial was born!I've been working on it consistently as a sort of pet project / passion. I've always enjoyed writing documentation and reports, but technical tutorials are new to me. That's why I'm here asking for feedback! Thanks in advance.
