Production ready Koa2 boilerplate.

KOACH

Production ready boilerplate for building APIs with koa2 using mongodb as the database and http/2 as the communication protocol.

Description

This project covers basic necessities of most APIs.

• Authentication (passport & jwt)
• Database (mongoose)
• Testing (mocha)
• http/2 support for websites and apis
• Doc generation with apidoc
• linting using standard
• Contains two versions of API

Please note, if you are planning to use this boilerplate for creating a web application then the 'https' protocol should be used to access its pages.

Visit https://localhost:3000/ to access the root page.

Requirements

• node = v10.15.3
• MongoDB

.env Configuration

To simulate environment variables in Dev environment, please create .env file at the root location and define the following properties -

NODE_ENV=production                                 // Node environment development/production
PORT=8000                                           // Server Port
SESSION=0.0.0.0                                     // secret-boilerplate-token
JWT_SECRET=This_Should_be_32_characters_long        // Jwt secret
DATABASE_URL=mongodb://localhost:27017/koach-dev    // Mongo database url
#DATABASE_URL=mongodb://mongodb:27017/koach-dev     // Mongo database url while using docker
DB_PATH=/home/ulap28/work/systango-frameworks       // path where database volumen mounted.

Usage

• npm start Start server on development mode with Nodemon
• npm run prod Start server on production mode with PM2
• npm run docs Generate API documentation
• npm test Run mocha tests

Running the server in Docker Container

Prerequisite For Docker Configuration : Docker and docker compose must be installed on the system.

Steps to run app in docker container :

1. CD to project dir
2. Create build using cmd: $ docker-compose build
3. Start the server in daemon thread using cmd: $ docker-compose up -d
4. Stop the server using cmd : $ docker-compose down
