What is AdonisJS?

MVC Framework for NodeJS to write webapps with less code

MVC Pattern

Define a Model

  'use strict'

  const Lucid = use('Lucid')

  class User extends Lucid {

  }
            

Using Model

  const User = use('App/Model/User')

  // All Users
  const users = yield User.all()

  // Using where clause
  const activeUsers = yield User.query()
    .where('status', 'active').fetch()
            

Example Of Controller

  const User = use('App/Model/User')

  class UsersController {

    * index (request, response) {
      const users = yield User.all()
      yield response.sendView('users.list', {
        users: users.toJSON()
      })
    }

  }
            

Example Of View

  

    {% for user in users %}
      
{{ user.username }}
    {% endfor %}

Framework concept and Features

Basic Routing in AdonisJs

  const Route = use('Route')

  Route.get('/', function * (request, response) {
    response.send('This is the home page')
  })
            

Routing Middleware

  const Route = use('Route')

  Route
    .get('/profile', 'UserController.profile')
    .middleware('auth')
            

Interactive Shell A.k.a Ace

Active Record ORM

  yield User.all()
  yield User.query().where('status', 'active').fetch()
            

Defining database relations

  class User extends Lucid {

    profile () {
      return this.hasOne('App/Model/Profile')
    }

    posts () {
      return this.hasMany('App/Model/Post')
    }

  }
            

Creating New Model

  ./ace make:model User

  # or with migration
  ./ace make:model User --migration
            

app/Model/User.js

  'use strict'

  const Lucid = use('Lucid')

  class User extends Lucid {
  }
            

Lucid Methods

query(), fetch(), first(), findBy(key, value), find(value), all(), ids(), pair(lhs, rhs), paginate(page, [perPage=20]), pick([limit=1]), pickInverse([limit=1]), create(values), save(), createMany(), findOrFail(value), findByOrFail(key, value), findOrCreate (whereAttributes, values), withTrashed()

etc...

Migrations

Basic Migration Example

 ./ace make:migration users --create=users
            

  // Output
  create: database/migrations/1464437815620_users.js
            

  'use strict'

  const Schema = use('Schema')

  class UsersSchema extends Schema {
    up () {
      this.create('users', (table) => {
        table.increments()
        table.timestamps()
      })
    }

    down () {
      this.drop('users')
    }
  }

  module.exports = UsersSchema
            

Seeds And Factories

  // database/factory.js

  const Factory = use('Factory')

  Factory.blueprint('App/Model/User', (fake) => {
    return {
      username: fake.username(),
      email: fake.email(),
      password: fake.password(),
      firstName: fake.first(),
      lastName: fake.last()
    }
  })
            

  // database/seeds/Database.js

  'use strict'

  const Factory = use('Factory')

  class DatabaseSeeder {
    * run () {
      yield Factory.model('App/Model/User').create(5)
    }
  }

  module.exports = DatabaseSeeder
            

  ./ace db:seed

Why AdonisJS?

1. Work on ideas, instead of deciding or downloading bunch of modules everytime.

2. Hiring developers are easy as you and the one you are about to hire will be working on the same standards and conventions.

3. The framework makes use of latest inbuilt ES2015 features to get rid of spaghetti code.

4. AdonisJs ships with a bunch of 1st party components known as providers. Writing entire web server is a matter of weeks(if not days).
