This course is a detailed guide to AdonisJs. AdonisJs, inspired by Laravel, is a Node.js framework that allows developers to build full-stack web applications and micro-API servers. 

In this course, you will cover the fundamentals: routes, controllers, middleware, hooks, and more. Each chapter contains code examples and illustrations to enhance your learning, and you will also be able to quiz yourself on the materials covered. 

By the time you are done with the course, you'll have plenty of hands-on practice, and will be able to confidently write your full-stack applications in AdonisJs.

Building Full-Stack Web Applications with AdonisJs

Redis saves session values in a file on a server.

Redis saves session values in a file on a server.

Username must be longer than 3 characters.

Username must be at least 5 characters long.

Take a look at **app/Validators/Test.js** below:

```
'use strict'

class Test {
  get rules () {
    return {
      username: 'required|min:5',
    }
  }
  get messages() { 
    return {
    'username.required': 'Username is required',
    'username.min': 'Username must be at least 5 characters long'
    }
  }
  async fails(errorMessages) { 
    this.ctx.session.withErrors(errorMessages[0]).flashAll();
    return this.ctx.response.redirect('back');
  }
}

module.exports = Test
```

What will be the error message if we enter "Ted" as the username?

Take a look at app/Validators/Test.js below:
<pre><code>'use strict'

class Test {
 get rules () {
 return {
 username: 'required|min:5',
 }
 }
 get messages() { 
 return {
 'username.required': 'Username is required',
 'username.min': 'Username must be at least 5 characters long'
 }
 }
 async fails(errorMessages) { 
 this.ctx.session.withErrors(errorMessages[0]).flashAll();
 return this.ctx.response.redirect('back');
 }
}

module.exports = Test
</code></pre>
What will be the error message if we enter “Ted” as the username?

What will be the output of the following code?

```
'use strict'

const Route = use('Route')

Route.get('/logger', ({ request }) => {
  const Logger = use('Logger')
  Logger.warning('Some message')
  return 'Logger'
})
```

What will be the output of the following code?
<pre><code>'use strict'

const Route = use('Route')

Route.get('/logger', ({ request }) =&gt; {
 const Logger = use('Logger')
 Logger.warning('Some message')
 return 'Logger'
})
</code></pre>

`TestController.postForm` will be called even if the validation defined in **app/Validators/Test.js** fails.

```
use strict

const Route = use('Route')

Route.get('/form', 'TestController.getForm')
Route.post('/form', 'TestController.postForm').validator('Test')
```

<code>TestController.postForm</code> will be called even if the validation defined in app/Validators/Test.js fails.
<pre><code>use strict

const Route = use('Route')

Route.get('/form', 'TestController.getForm')
Route.post('/form', 'TestController.postForm').validator('Test')
</code></pre>

Test yourself on the session, validator, and logger.
