Controllers

📝 Generics Controllers

Generic controllers is a library that allows you to create controllers for your models in a simple way, it is compatible with Sequelize and Typegoose using express as a server. soon it will be compatible with other servers and ORMs/ODMs.

📦 Installation

Note

You need to have one of the ORM or ODM to manage the data before. The supported ORMs/ODMs are Sequelize and Typegoose wich needs moongose, so you need to install it too if you want the whole experience of the library install it.

📖 Usage

Sequelize

import { SequelizeBaseEntity } from '@gnx-utilities/models'
import { SequelizeService } from '@gnx-utilities/services'
import { DataTypes, Sequelize } from 'sequelize'
import { GenericControllerService } from '@gnx-utilities/controllers'
import { Router } from 'express'
import type { UUID } from 'node:crypto'
const sequelize = new Sequelize({
  dialect: 'sqlite',
  storage: './db/test.sqlite'
})

class User extends SequelizeBaseEntity {
  declare id: UUID
  declare firstName: string
  declare lastName: string
  declare email: string
}

User.init(
  {
    id: { type: DataTypes.UUID, primaryKey: true, defaultValue: DataTypes.UUIDV4 },
    firstName: { type: DataTypes.STRING },
    lastName: { type: DataTypes.STRING },
    email: { type: DataTypes.STRING },
    isDeleted: { type: DataTypes.BOOLEAN, defaultValue: false }
  },
  { sequelize, modelName: 'person' }
)


class UserService extends SequelizeService<User> {
  constructor () {
    super(User)
  }
}

class UserController extends GenericControllerService<User, UserService> {
  constructor () {
    super(new UserService())
  }
}
const controller = new UserController()
const router: Router = Router()

router.get('/list', controller.getAll)
router.get('/get/:id', controller.getById)
router.get('/paginate', controller.getAllPaginated)
router.get('/all', controller.getAllWithDeleted)
router.get('/deleted', controller.getAllDeleted)
router.post('/create', controller.create)
router.post('/createMany', controller.bulkCreate)
router.patch('/update/:id', controller.update)
router.delete('/hide/:id', controller.softDelete)
router.patch('/restore/:id', controller.restore)
router.delete('/delete/:id', controller.hardDelete)
router.delete('/deleteAll', controller.bulkDelete)

export { router, sequelize }

Typegoose

import { TypegooseBaseEntity } from '@gnx-utilities/models'
import { TypegooseService } from '@gnx-utilities/services'
import { getModelForClass, prop } from '@typegoose/typegoose'
import { Router } from 'express'
import { connect } from 'mongoose'
import { GenericControllerService } from '@gnx-utilities/controllers'

const uri =
'mongodb://localhost:27017/?readPreference=primary&ssl=false&directConnection=true'

const connection = async (): Promise<void> => {
  await connect(uri, { dbName: 'test' })
}

export class User extends TypegooseBaseEntity {
  @prop({ type: String })
  declare firstName: string

  @prop({ type: String })
  declare lastName: string

  @prop({ type: String })
  declare email: string
}

export const UserModel = getModelForClass(User)

export class UserService extends TypegooseService<User> {
  constructor() {
    super(UserModel)
  }
}

export class UserController extends GenericControllerService<User, UserService> {
  constructor() {
    super(new UserService())
  }
}

const controller = new UserController()

const router: Router = Router()

router.get('/list', controller.getAll)
router.get('/get/:id', controller.getById)
router.get('/paginate', controller.getAllPaginated)
router.get('/all', controller.getAllWithDeleted)
router.get('/deleted', controller.getAllDeleted)
router.post('/create', controller.create)
router.post('/createMany', controller.bulkCreate)
router.patch('/update/:id', controller.update)
router.delete('/hide/:id', controller.softDelete)
router.patch('/restore/:id', controller.restore)
router.delete('/delete/:id', controller.hardDelete)
router.delete('/deleteAll', controller.bulkDelete)

export { router, connection }

server

import express, { json, urlencoded } from 'express'
import type { Application } from 'express'
import { sequelizeRouter, sequelize } from './sequelize'
import { typegooseRouter, connection } from './typegoose'

const app: Application = express()

app.use(json())
app.use(urlencoded({ extended: true }))

app.get('/', (req, res) => {
  res.send('Hello World')
})
app.use('/api/sequelize', sequelizeRouter)
app.use('/api/typegoose', typegooseRouter)

async function handleConnection(): Promise<void> {
  try {
    await Promise.all([connection(), sequelize.sync({ alter: true })])
  } catch (err) {
    console.error(`Unable to connect to the database: ${err}`)
  }
}

await handleConnection()

const port = 4000
app.listen(port, () => {
  console.log(`Example app listening at http://localhost:${port}`)
})
export { app, handleConnection }
