Node.js API boilerplate

Piece of my thoughts about Node.js architecture.

supra-api-nodejs: A little bit about Node.js RESTful APIs Architecture (RU)

Highlights:

• Modular RESTful API
• ES6 Classes
• Action based
• SQL based (PostgreSQL with objection.js)
• Migrations(knex.js)
• Auth (JWT/Access-token/Refresh-token)
• Cookie support
• Role based access control
• Request validation
• CRUD(users, posts resources)
• Automated API documentation
• Full authentication/authorization and user registration flow implemented
• Tests(e2e)

Key points:

0. Monolith first

Supra-api-nodejs its about monolith first approach. But this does not prevent you from using it in a microservice architecture as well.

1. Controller layer

Each entity have own controller class it slim layer representing resource mapping(routing)

class PostsController extends BaseController {
  static get router () {
    router.get('/', this.actionRunner(actions.ListAction))
    router.get('/:id', this.actionRunner(actions.GetByIdAction))
    router.post('/', this.actionRunner(actions.CreateAction))
    router.patch('/:id', this.actionRunner(actions.UpdateAction))
    router.delete('/:id', this.actionRunner(actions.RemoveAction))

    return router
  }
}

For example PostsController implements post entity routes. Each route fires own action.

2. Action layer

It's a class encapsulated request validation, permission verification and business logic. One file, one class, one REST operation, one use case.

3. DAO layer

Implement data access methods.

4. Model layer

Represent models schemas and validation rules. There is no other logic only model fields and validation rules.

Development:

Install global dependencies:

npm i -g knex nodemon

Setup database:

1. Install PostgreSQL (https://postgresapp.com/downloads.html (for Mac OS))
2. Create some DB (https://eggerapps.at/postico/ (for Mac OS))

Go ahead...

cd /supra-api-nodejs

• cp .env.example .env
• Set required credential in .env

Run migration to set base SQL schema

knex migrate:latest

Run server

npm run start // prod mode
npm run dev // dev mode
