Laravel Livewire Add or Remove Dynamically Input Fields Example

Here, i will show you how to works laravel livewire add more dynamically input fields. i explained simply about laravel livewire add or remove dynamically input fields. This tutorial will give you simple example of laravel livewire add more input fields example. i would like to share with you add remove dynamic textbox laravel livewire.

In this tutorial, we will create simple add remove dynamic textbox example using laravel livewire. you can use laravel livewire with laravel 6, laravel 7 and laravel 8 version.

Livewire is a full-stack framework for Laravel framework that makes building dynamic interfaces simple, without leaving the comfort of Laravel. if you are using livewire with laravel then you don’t worry about writing jquery ajax code, livewire will help to write very simple way jquery ajax code using php. without page refresh laravel validation will works, form will submit etc.

Here, i will give you very simple example to contacts table with name and phone number and i will store that data to database without refresh page in single form. we will use only livewire/livewire package.

So, let’s follow bellow step and you will get bellow layout:

Step 1 : Install Laravel 8

first of all we need to get fresh Laravel 8 version application using bellow command, So open your terminal OR command prompt and run bellow command:

composer create-project --prefer-dist laravel/laravel blog

Step 2 : Create Migration and Model

Here, we need create database migration for files table and also we will create model for files table.

php artisan make:migration create_contacts_table

Migration:

<?php

use Illuminate\Database\Migrations\Migration;
use Illuminate\Database\Schema\Blueprint;
use Illuminate\Support\Facades\Schema;

class CreateContactcTable extends Migration
{
    /**
     * Run the migrations.
     *
     * @return void
     */
    public function up()
    {
        Schema::create('contacts', function (Blueprint $table) {
            $table->id();
            $table->string('name');
            $table->string('phone');
            $table->timestamps();
        });
    }

    /**
     * Reverse the migrations.
     *
     * @return void
     */
    public function down()
    {
        Schema::dropIfExists('contacts');
    }
}
php artisan migrate

now we will create Contact model by using following command:

php artisan make:model Contact

App/Models/Contact.php

<?php

namespace App\Models;

use Illuminate\Database\Eloquent\Factories\HasFactory;
use Illuminate\Database\Eloquent\Model;

class Contact extends Model
{
    use HasFactory;

    protected $fillable = [
        'name', 'phone'
    ];
}

Step 3: Install Livewire

now in this step, we will simply install livewire to our laravel 8 application using bellow command:

composer require livewire/livewire

Step 4: Create Component

Now here we will create livewire component using their command. so run bellow command to create add more component.

php artisan make:livewire contacts

Now they created fies on both path:

app/Http/Livewire/Contacts.php

resources/views/livewire/contacts.blade.php

Now both file we will update as bellow for our contact us form.

app/Http/Livewire/Contacts.php

<?php

namespace App\Http\Livewire;

use Livewire\Component;
use App\Models\Contact;
use App\Http\Livewire\Field;
use Illuminate\Http\Request;

class Contacts extends Component
{
    public $contacts, $name, $phone, $contact_id;
    public $updateMode = false;
    public $inputs = [];
    public $i = 1;

    /**
     * Write code on Method
     *
     * @return response()
     */
    public function add($i)
    {
        $i = $i + 1;
        $this->i = $i;
        array_push($this->inputs ,$i);
    }

    /**
     * Write code on Method
     *
     * @return response()
     */
    public function remove($i)
    {
        unset($this->inputs[$i]);
    }

    /**
     * Write code on Method
     *
     * @return response()
     */
    public function render()
    {
        $this->contacts = Contact::all();
        return view('livewire.contacts');
    }

    /**
     * Write code on Method
     *
     * @return response()
     */
    private function resetInputFields(){
        $this->name = '';
        $this->phone = '';
    }

    /**
     * Write code on Method
     *
     * @return response()
     */
    public function store()
    {
        $validatedDate = $this->validate([
                'name.0' => 'required',
                'phone.0' => 'required',
                'name.*' => 'required',
                'phone.*' => 'required',
            ],
            [
                'name.0.required' => 'name field is required',
                'phone.0.required' => 'phone field is required',
                'name.*.required' => 'name field is required',
                'phone.*.required' => 'phone field is required',
            ]
        );

        foreach ($this->name as $key => $value) {
            Contact::create(['name' => $this->name[$key], 'phone' => $this->phone[$key]]);
        }

        $this->inputs = [];

        $this->resetInputFields();

        session()->flash('message', 'Contact Has Been Created Successfully.');
    }
}

resources/views/livewire/file-upload.blade.php

<div>
    @if (session()->has('message'))
        <div class="alert alert-success">

TS-mockito: Mocking Library for TypeScript

TS-mockito

Mocking library for TypeScript inspired by http://mockito.org/

1.x to 2.x migration guide

1.x to 2.x migration guide

Main features

  • Strongly typed
  • IDE autocomplete
  • Mock creation (mock) (also abstract classes) #example
  • Spying on real objects (spy) #example
  • Changing mock behavior (when) via:
  • Checking if methods were called with given arguments (verify)
    • anything, notNull, anyString, anyOfClass etc. - for more flexible comparision
    • once, twice, times, atLeast etc. - allows call count verification #example
    • calledBefore, calledAfter - allows call order verification #example
  • Resetting mock (reset, resetCalls) #example, #example
  • Capturing arguments passed to method (capture) #example
  • Recording multiple behaviors #example
  • Readable error messages (ex. 'Expected "convertNumberToString(strictEqual(3))" to be called 2 time(s). But has been called 1 time(s).')

Installation

npm install ts-mockito --save-dev

Usage

Basics

// Creating mock
let mockedFoo:Foo = mock(Foo);

// Getting instance from mock
let foo:Foo = instance(mockedFoo);

// Using instance in source code
foo.getBar(3);
foo.getBar(5);

// Explicit, readable verification
verify(mockedFoo.getBar(3)).called();
verify(mockedFoo.getBar(anything())).called();

Stubbing method calls

// Creating mock
let mockedFoo:Foo = mock(Foo);

// stub method before execution
when(mockedFoo.getBar(3)).thenReturn('three');

// Getting instance
let foo:Foo = instance(mockedFoo);

// prints three
console.log(foo.getBar(3));

// prints null, because "getBar(999)" was not stubbed
console.log(foo.getBar(999));

Stubbing getter value

// Creating mock
let mockedFoo:Foo = mock(Foo);

// stub getter before execution
when(mockedFoo.sampleGetter).thenReturn('three');

// Getting instance
let foo:Foo = instance(mockedFoo);

// prints three
console.log(foo.sampleGetter);

Stubbing property values that have no getters

Syntax is the same as with getter values.

Please note, that stubbing properties that don't have getters only works if Proxy object is available (ES6).

Call count verification

// Creating mock
let mockedFoo:Foo = mock(Foo);

// Getting instance
let foo:Foo = instance(mockedFoo);

// Some calls
foo.getBar(1);
foo.getBar(2);
foo.getBar(2);
foo.getBar(3);

// Call count verification
verify(mockedFoo.getBar(1)).once();               // was called with arg === 1 only once
verify(mockedFoo.getBar(2)).twice();              // was called with arg === 2 exactly two times
verify(mockedFoo.getBar(between(2, 3))).thrice(); // was called with arg between 2-3 exactly three times
verify(mockedFoo.getBar(anyNumber()).times(4);    // was called with any number arg exactly four times
verify(mockedFoo.getBar(2)).atLeast(2);           // was called with arg === 2 min two times
verify(mockedFoo.getBar(anything())).atMost(4);   // was called with any argument max four times
verify(mockedFoo.getBar(4)).never();              // was never called with arg === 4

Call order verification

// Creating mock
let mockedFoo:Foo = mock(Foo);
let mockedBar:Bar = mock(Bar);

// Getting instance
let foo:Foo = instance(mockedFoo);
let bar:Bar = instance(mockedBar);

// Some calls
foo.getBar(1);
bar.getFoo(2);

// Call order verification
verify(mockedFoo.getBar(1)).calledBefore(mockedBar.getFoo(2));    // foo.getBar(1) has been called before bar.getFoo(2)
verify(mockedBar.getFoo(2)).calledAfter(mockedFoo.getBar(1));    // bar.getFoo(2) has been called before foo.getBar(1)
verify(mockedFoo.getBar(1)).calledBefore(mockedBar.getFoo(999999));    // throws error (mockedBar.getFoo(999999) has never been called)

Throwing errors

let mockedFoo:Foo = mock(Foo);

when(mockedFoo.getBar(10)).thenThrow(new Error('fatal error'));

let foo:Foo = instance(mockedFoo);
try {
    foo.getBar(10);
} catch (error:Error) {
    console.log(error.message); // 'fatal error'
}

Custom function

You can also stub method with your own implementation

let mockedFoo:Foo = mock(Foo);
let foo:Foo = instance(mockedFoo);

when(mockedFoo.sumTwoNumbers(anyNumber(), anyNumber())).thenCall((arg1:number, arg2:number) => {
    return arg1 * arg2; 
});

// prints '50' because we've changed sum method implementation to multiply!
console.log(foo.sumTwoNumbers(5, 10));

Resolving / rejecting promises

You can also stub method to resolve / reject promise

let mockedFoo:Foo = mock(Foo);

when(mockedFoo.fetchData("a")).thenResolve({id: "a", value: "Hello world"});
when(mockedFoo.fetchData("b")).thenReject(new Error("b does not exist"));

Resetting mock calls

You can reset just mock call counter

// Creating mock
let mockedFoo:Foo = mock(Foo);

// Getting instance
let foo:Foo = instance(mockedFoo);

// Some calls
foo.getBar(1);
foo.getBar(1);
verify(mockedFoo.getBar(1)).twice();      // getBar with arg "1" has been called twice

// Reset mock
resetCalls(mockedFoo);

// Call count verification
verify(mockedFoo.getBar(1)).never();      // has never been called after reset

You can also reset calls of multiple mocks at once resetCalls(firstMock, secondMock, thirdMock)

Resetting mock

Or reset mock call counter with all stubs

// Creating mock
let mockedFoo:Foo = mock(Foo);
when(mockedFoo.getBar(1)).thenReturn("one").

// Getting instance
let foo:Foo = instance(mockedFoo);

// Some calls
console.log(foo.getBar(1));               // "one" - as defined in stub
console.log(foo.getBar(1));               // "one" - as defined in stub
verify(mockedFoo.getBar(1)).twice();      // getBar with arg "1" has been called twice

// Reset mock
reset(mockedFoo);

// Call count verification
verify(mockedFoo.getBar(1)).never();      // has never been called after reset
console.log(foo.getBar(1));               // null - previously added stub has been removed

You can also reset multiple mocks at once reset(firstMock, secondMock, thirdMock)

Capturing method arguments

let mockedFoo:Foo = mock(Foo);
let foo:Foo = instance(mockedFoo);

// Call method
foo.sumTwoNumbers(1, 2);

// Check first arg captor values
const [firstArg, secondArg] = capture(mockedFoo.sumTwoNumbers).last();
console.log(firstArg);    // prints 1
console.log(secondArg);    // prints 2

You can also get other calls using first(), second(), byCallIndex(3) and more...

Recording multiple behaviors

You can set multiple returning values for same matching values

const mockedFoo:Foo = mock(Foo);

when(mockedFoo.getBar(anyNumber())).thenReturn('one').thenReturn('two').thenReturn('three');

const foo:Foo = instance(mockedFoo);

console.log(foo.getBar(1));    // one
console.log(foo.getBar(1));    // two
console.log(foo.getBar(1));    // three
console.log(foo.getBar(1));    // three - last defined behavior will be repeated infinitely

Another example with specific values

let mockedFoo:Foo = mock(Foo);

when(mockedFoo.getBar(1)).thenReturn('one').thenReturn('another one');
when(mockedFoo.getBar(2)).thenReturn('two');

let foo:Foo = instance(mockedFoo);

console.log(foo.getBar(1));    // one
console.log(foo.getBar(2));    // two
console.log(foo.getBar(1));    // another one
console.log(foo.getBar(1));    // another one - this is last defined behavior for arg '1' so it will be repeated
console.log(foo.getBar(2));    // two
console.log(foo.getBar(2));    // two - this is last defined behavior for arg '2' so it will be repeated

Short notation:

const mockedFoo:Foo = mock(Foo);

// You can specify return values as multiple thenReturn args
when(mockedFoo.getBar(anyNumber())).thenReturn('one', 'two', 'three');

const foo:Foo = instance(mockedFoo);

console.log(foo.getBar(1));    // one
console.log(foo.getBar(1));    // two
console.log(foo.getBar(1));    // three
console.log(foo.getBar(1));    // three - last defined behavior will be repeated infinity

Possible errors:

const mockedFoo:Foo = mock(Foo);

// When multiple matchers, matches same result:
when(mockedFoo.getBar(anyNumber())).thenReturn('one');
when(mockedFoo.getBar(3)).thenReturn('one');

const foo:Foo = instance(mockedFoo);
foo.getBar(3); // MultipleMatchersMatchSameStubError will be thrown, two matchers match same method call

Mocking interfaces

You can mock interfaces too, just instead of passing type to mock function, set mock function generic type Mocking interfaces requires Proxy implementation

let mockedFoo:Foo = mock<FooInterface>(); // instead of mock(FooInterface)
const foo: SampleGeneric<FooInterface> = instance(mockedFoo);

Mocking types

You can mock abstract classes

const mockedFoo: SampleAbstractClass = mock(SampleAbstractClass);
const foo: SampleAbstractClass = instance(mockedFoo);

You can also mock generic classes, but note that generic type is just needed by mock type definition

const mockedFoo: SampleGeneric<SampleInterface> = mock(SampleGeneric);
const foo: SampleGeneric<SampleInterface> = instance(mockedFoo);

Spying on real objects

You can partially mock an existing instance:

const foo: Foo = new Foo();
const spiedFoo = spy(foo);

when(spiedFoo.getBar(3)).thenReturn('one');

console.log(foo.getBar(3)); // 'one'
console.log(foo.getBaz()); // call to a real method

You can spy on plain objects too:

const foo = { bar: () => 42 };
const spiedFoo = spy(foo);

foo.bar();

console.log(capture(spiedFoo.bar).last()); // [42]
