node-express-typescript-starter

This is a starter Node.js API server project built on Express. It has Docker support as well as Jest, ESLint, and a local development server. Everything is in Typescript.

This was initially built for a Google Cloud Run project, but it could be used anywhere.

Prerequisite

Node 16

Nice to have

Getting started

Clone the repository

git clone --depth=1 https://github.com/elgharabawy/node-express-typescript-starter.git <project_name>

Install dependencies

cd <project_name>
npm install

Run local development server

npm run dev

Using postman, curl, or your browser

GET http://localhost:8080
GET http://localhost:8080/articles
GET http://localhost:8080/articles/test

To use ESLint

npm run lint

To run tests

npm test

ENV variables

The project uses dotenv to parse environment variables. To add environment variables to your project, simply, create a .env file in the root folder of the project. You can then reference it using process.env.VAR_NAME. For example, to change Node.js mode, simply add NODE_ENV=production or NODE_ENV=development to your .env file to change Node.js mode to production or development accordingly.

Remeber: it's not a good idea to push .env files to your repo!

Logging

This project uses Winston and Morgan for logging. Winston is exported as a logger and can be used to log custom messages on demand. Also, it can be extended to push logs to files, external database, or any logging service.

Morgan is used as an http logger middleware for Express and the logs are routed through Winston, so everything is nicely bundled in one log stream.

All of these logs are written to console during development. Feel free to add production-specific loggers as and when needed.
