If you have not added Prettier and ESlint into your project you are missing a lot of out of box configuration and code formatting.It's simple to add them and follow industry based best practice and adding them will not even take 2 minutes.

So here are the steps to add them into your project.

• Add Prettier as an extension to your VSCode, or if you not using VSCode install it globally using npm i -g prettier

• Add ".prettierrc" file to your project root directory

• Add following code into ".prettierrc"

{ "semi": false, "trailingComma": "all", "singleQuote": true, "printWidth": 70 }

Add followig two packages to your project

npm install --save-dev eslint-config-prettier eslint-plugin-prettier

Add .eslintrc.json

Add following code to ".eslintrc.json"

{  "extends": ["prettier"],  "plugins": ["prettier"],  "rules": { "prettier/prettier": ["error"] }}

Thats it, your project to s configured to use best practices based on Prettier and ESLint.

Follow below steps to run a HTTPS server for your nodeJs app. To run your nodesJS + ExpressJs app on HTTPS, you need to first create a SSL certificate. To do so we will use openssl. Run below command on your terminal

openssl req -x509 -newkey rsa:2048 -keyout keytmp.pem -out cert.pem -days 365

Run below command on same terminal after cert.pem and keytmp.pem has been generated

openssl rsa -in keytmp.pem -out key.pem

Include your keys and certificatio to your app by moving them to appropraiate folder

Once you have all files in right place, update your server.js/index.js file for ExpressJS, as shown below

import express from 'express'; import https from 'https import fs from 'fs'
const port = process.env.PORT || 3003;
const key = fs.readFileSync('./server/key.pem') const cert = fs.readFileSync('./server/cert.pem'),
// we will pass our 'app' to 'https' server const server =https.createServer({ key: , cert: passphrase: 'Your Pass phrase' },app);
app.get('/', (req, res) => { res.send('This is an secure server') });
server.listen(port, () => { console.log('listening on 3003') });

Now if you run your app you can navigate to https://localhost:3003, your browser will throw a long message warning about validatiy of the SSL certificate, since it has been genrated locally by you and not generated by a Standard Certificate issuer. You can igmore and Click on continue to run your server on HTTPS.
