najs-eloquent-mongodb v0.1.0

najs-eloquent-mongodb

Mongodb driver for NajsEloquent - an ORM written in Typescript, inspired by Laravel Eloquent.

Installation

Add najs-binding, najs-eloquent, najs-eloquent-mongodb

yarn add najs-binding najs-eloquent najs-eloquent-mongodb

or

npm install najs-binding najs-eloquent najs-eloquent-mongodb

That's it.

Define Model runs with MongodbDriver

You can register MongodbDriver as default driver by this way

import { DriverProvider } from 'najs-eloquent'
import { MongodbDriver } from 'najs-eloquent-mongodb'

DriverProvider.register(MongodbDriver, 'mongodb', true)

Or if you want to use MongodbDriver for some specific models only, you can extends from MongodbModel instead of Model

import { MongodbModel } from 'najs-eloquent-mongodb'

export class User extends MongodbModel {
  // define a property belongs to User model
  email: string

  // define a class name which used for Dependency injection
  // (this feature provided by "najs-binding" package)
  getClassName() {
    return 'YourNamespace.User'
  }
}

// Register the User class
MongodbModel.register(User)

Connect to database and provide custom MongoClient instance

You may want to connect and provide your own MongoClient instance, you can do it by using .bind() function of the najs-binding package. Note: Please ensure that this file is loaded before using najs-eloquent.

import { bind } from 'najs-binding'
import { MongodbProviderFacade } from 'najs-eloquent-mongodb'

// Load your mongodb instance instead of mongodb dependency in "najs-eloquent-mongodb" package
import { Db, MongoClient } from 'mongodb'

export class YourMongodbProvider {
  static className: string = 'YourNamespace.YourMongodbProvider'

  getClassName() {
    return YourMongodbProvider.className
  }

  connect(url: string): Promise<this> {
    return new Promise((resolve, reject) => {
      MongoClient.connect(
        url,
        { useNewUrlParser: true },
        (error: any, client: MongoClient) => {
          if (error) {
            return reject(error)
          }

          this.mongoClient = client
          resolve(this)
        }
      )
    })
  }

  close(): this {
    if (this.mongoClient) {
      this.mongoClient.close()
    }

    return this
  }

  getMongoClient(): MongoClient {
    return this.mongoClient
  }

  getDatabase(dbName?: string): Db {
    return this.mongoClient && this.mongoClient.db(dbName)
  }
}

bind('NajsEloquent.Provider.MongodbProvider', YourMongodbProvider.className)

// Reload the facade, then najs-eloquent will use your mongodb instance
MongodbProviderFacade.reloadFacadeRoot()
