autoRestfulPrisma

Simple and easy to use automated MVC-like REST API backend built using Express, and Prisma as the model.

You could say it's the continuation of my old repo.

Installation

Clone this repo.

git clone https://github.com/itsfaqih/autoRestfulPrisma.git
cd autoRestfulPrisma
npm install

Setup database configuration.

cp ./prisma/.env.example ./prisma/.env

Change the DATABASE_URL to your database URL, and the provider in schema.prisma datasource. You can see more detailed guides here.

or you could just try it quick using the populated demo database (the dev.db) without changing any configuration.

Introspect the database with Prisma

npx prisma introspect

Generate Prisma Client

npx prisma generate

Usage

Repository

// src/repositories/UserRepository.ts (you can create your own)
import ResourceRepository from '../cores/resources/ResourceRepository' // REST boilerplate repository

class UserRepository extends ResourceRepository { // or extend Repository
  constructor() {
    super()
    this.setModel(this.prisma.users) // Set the model
  }

  async findByEmail(email: string) { // Create your own custom method
    try {
      return await this.model.findOne({
        where: {
          email
        }
      })
    } catch (error) {
      throw error
    } finally {
      await this.prisma.disconnect()
    }
  }
}

export default UserRepository

Controller

// src/controllers/UserController.ts (you can create your own)
import ResourceController from '../cores/resources/ResourceController' // REST boilerplate controller
import UserRepository from '../repositories/UserRepository'

class UserController extends ResourceController { // or extend Controller
  constructor() {
    super(new UserRepository()) // Pass the repository
  }

  async whoseEmail(req: Request, res: Response) { // Create your own custom method
    try {
      const user = await this.repository.findByEmail(req.query.email)

      if (user != null) {
        res.send({ data: user })
      } else {
        res.send({ data: null })
      }
    } catch (error) {
      res.status(400).send({ error: error.message })
    }
  }
}

export default UserController

Route

// src/routes.ts
// Import the controller
import UserController from './controllers/UserController'

module.exports = [
  {
    endpoint: '/users', // Set the endpoint url
    resource: true, // Set it true if it's REST controller
    controller: new UserController() // initialize the controller
  },
  {
    endpoint: '/whose_email', // Custom endpoint
    controller: (new UserController()).whoseEmail // Select the handler,
    method: 'GET' // Select the HTTP Method, it's GET by default
  }
]

If you're using the Resource, it will generate all restful endpoints as follows:

GET /users (get all user data)
POST /users (create new user)
GET /users/:id (get one user data)
PUT /users/:id (update user data)
DELETE /users/:id (delete user data)

NB: id parameter is using "id" field by default.

Using Scaffolding

You can also generate the Controller, Repository, and Route automatically using cli.

node ./scaffolds/cli make:rest <Entity> <Table>:optional

For example:

# Generate UserController, UserRepository, and /users endpoint
node ./scaffolds/cli User users 

# Generate BookController, BookRepository, and /book endpoint
node ./scaffolds/cli Book

Run the REST API Server

The server will run at port 3000 by default

npm run dev
