Node.js

1. Follow the steps in Setting up a new TypeScript project

2. Rename *.js files to *.ts

3. Fix all TypeScript warnings

   You should see the warnings when you open up the TypeScript files if you’re using vscode. Otherwise, you can run:

   npx tsc
   

   • If you’re getting TypeScript warnings for a package that has types and you’re using require, try using import instead. e.g.

     From:

     const { config, createLogger, format, transports } = require('winston');
     

     To:

     import { config, createLogger, format, transports } from 'winston';
