Generate Express TypeScript

This cli tool generates a thin, unopinionated Express application with TypeScript. It's designed to create a project structure, initialize version control, install dependencies, and configure TypeScript, ESLint, Prettier, and Jest for testing.

🍇 Features

🍦 Sets up an Express server with TypeScript

🍦 Configures ESLint with TypeScript support

🍦 Adds Prettier for code formatting

🍦 Sets up Jest and Supertest for endpoint testing

🍦 Initializes a new Git repository

🍦 Configures Husky for pre-commit hooks

🪵 Prerequisites

Before running this script, make sure you have the following installed:

• Node.js (v16 or higher)
• yarn (default package manager)
• git

🏰 Installation

Install the package globally using npm:

npm install -g generate-express-ts

Or using Yarn:

yarn global add generate-express-ts

🚂 Usage

After installing the package globally, you can set up a new Express TypeScript application by running:

generate-express-ts <project-name>

Replace <project-name> with your desired project directory name. If you don't specify a name, it defaults to my-express-ts-app.

The script will create a new directory with the given project name (or the default name) and set up the project structure and configurations within that directory.

🧳 What's Included

The script will create the following files and directories:

• .eslintrc.yml: ESLint configuration file
• .prettierrc.yml: Prettier configuration file
• .gitignore: Basic .gitignore file for a Node.js project
• app.ts: Entry point for the Express application
• app.spec.ts: Sample test file using Jest and Supertest
• tsconfig.json: TypeScript configuration file
• .lintstagedrc: Configuration for lint-staged
• package.json: Node.js package manifest with scripts for common tasks
• src/: Directory for source code
• src/api/: Directory for API endpoints
• src/api/health/: Health check endpoint, accessible at /api/health

🧸 Scripts

The generated package.json includes the following scripts:

• start: Runs the Express server using ts-node
• dev: Runs the Express server using nodemon
• build: Compiles TypeScript files to JavaScript in the dist directory
• test: Runs tests using Jest
• serve: Runs the Express server using node (requires build to be run first)
