Node with TS

This is a node.js basic API project using typescript.

Bootstrap a Node.js Project

Initialize a Node.js project within the project directory by creating a package.json file with default settings:

npm init -y

Install Project Dependencies

Your Node.js project requires a couple of dependencies to create a secure Express server with TypeScript. Install them like so:

npm i express body-parser ts-node typescript

npm i dotenv cors helmet

To use TypeScript effectively, you need to install type definitions for the packages you installed previously:

npm i -D @types/node @types/express @types/dotenv @types/cors @types/helmet

Initialize TypeScript in Node.js

npx tsc --init

Use Environmental Variables

touch .env

Populate the .env hidden file with the following variable that defines the port your server can use to listen for requests: PORT=2023

Create an Express App with TypeScript

mkdir src

Under this src directory, create a file named index.ts to serve as the entry point of the application:

touch src/index.ts
