Express TypeORM REST API Boilerplate

Awesome boilerplate code to get started with building RESTful API Services!
Typescript with NodeJS and Express as well as MongoDB integration with TypeORM
JSON Web Tokens (JWT) based User Authentication,
TypeDI dependency injections, testing with Jest, and a bunch more.
_{Made with ❤️ by Brian Min}

Why?

The main reason I decided to start this project is to provide a boilerplate for the NodeJS, Express, Typescript, TypeORM, MongoDB stack. Also with TypeORM, this boilerplate code can easily be modified to use MySQL, PostGreSQL, and many more. Tedious setting up of project structure, logging, testing, env and eslint is all done for you! Now you can focus on actually implementing the core functionalities and not spending hours setting up and configuring your project.

Try it out and feel free to raise any issues or create pull requests if you would like to contribute!

Features

• JWT based user authentication with jsonwebtoken and express-jwt.
• Dependency Injection with TypeDI.
• ORM with support for many databases (MySQL, PostgreSQL, MariaDB, SQLite, MongoDB, and more) with TypeORM.
• Clear and organised structure with different layers such as entities, services, middlewares, loaders, etc.
• Validation thanks to class-validator.
• Unit and Integration Testing with Jest.
• Security Features with Helmet.
• Role-based access control using a custom-built middleware.
• Simple Data Seeding with custom-built factories and Faker.js.
• Code generator for entity, service, route, factory, seed, test with a custom-built generator script and CLI tool Commander.

Getting Started

Step 1: Set up the Development Environment

Install Node.js and NPM

Install a MongoDB server or use MongoDB Atlas

Step 2: Create a new project

Fork or download this project and modify package.json for your new project.

Make a copy of the .env.example file and rename it to .env.

Create a new database and add the connection string in the .env file.

Install the required packages.

npm install

This installs all the dependencies with NPM.

Now your development environment should be ready to use!

Step 3: Serve your application

Go to the root directory and start your app with this npm script.

npm run dev

This starts a local server using nodemon and ts-node. The server base endpoint will be http://127.0.0.1:3000 where 3000 is the PORT variable you set in the .env file.

Scripts and Tasks

Install

• Install all dependencies with npm install

Linting

• Run code syntax and format checking using npm run lint which runs eslint.
• Automatically fix lint errors with npm run lint:fix.

Running MongoDB locally

For this step you need to install MongoDB Server

• Run npm run mongodb to start a local MongoDB server with it's data stored in .mongodb in the root directory.
• This is very useful for unit / integration testing.
• It's always a good idea to use a separate database for testing.

Tests

• Run unit tests using npm run test (for Windows users) or npm run test:unix (for Mac and Linux users).

Running the app in development

• Run npm run dev to start nodemon with ts-node.
• The server base endpoint will be http://127.0.0.1:3000 where 3000 is the PORT variable you set in the .env file.

Building and running the app in production

• Run npm run build to compile all the Typescript sources and generate JavaScript files.
• To start the built app located in build use npm start.

API Routes

The route prefix is /api by default, but you can change this in the .env file.

Project Structure

Logging

For logging we use winston.
