Expressjs + Typescript + Live reloading

A minimal Express.js server in Typescript with Live Reloading. Ready to be hosted on heroku.

Get Started

npm install
npm run dev

Server is ready at http://localhost:3000.

Edit src/index.ts, save file, server restarts automatically, refresh your browser to see the changes.

Static files

Files in the public/ folder are served statically, see http://localhost:3000/cover.jpg.

Environment variables

Create a .env file:

PORT=3000
STRIPE_PRIVATE_KEY=blablabla

Env vars are available in your app, eg. process.env.STRIPE_PRIVATE_KEY.

It is good practice to:

• not commit your .env file
• keep .env.example updated with empty value for sensitive key

Scripts in a nutshell

Scripts in package.json :

• npm run dev runs the server and automatically restart the server when a change is made in src folder.
• npm run build generates .js files from *.ts files.
• npm run start runs the node server from the generated index.js.

Deploy

This minimal project can be hosted on any platform that runs nodejs apps, such heroku, digital ocean, deta, etc.

Has been successfully deployed on heroku, see: https://expressjs-with-typescript.herokuapp.com/
