How vue js component is different from livewire component
Vue.js components and Laravel Livewire components are both used to build dynamic web interfaces, but they operate in different ways and have distinct characteristics. Here's a comparison between Vue.js and Livewire components along with a CRUD coding example for each:
Vue.js Components:
Client-Side Rendering: Vue.js components are rendered on the client-side, meaning that they run in the browser and interact with the DOM directly.
JavaScript: Vue.js components are written in JavaScript and allow for reactive updates to the UI based on data changes.
Separation of Concerns: Vue.js encourages a clear separation of concerns between the template (HTML), script (JavaScript), and style (CSS) of a component.
Interactivity: Vue.js components provide a rich set of features for building interactive UIs, including event handling, data binding, and component lifecycle hooks.
Example:
<!-- Vue.js Component Example -->
<template>
<div>
<input v-model="message">
<button @click="submit">Submit</button>
<p>{{ response }}</p>
</div>
</template>
<script>
export default {
data() {
return {
message: '',
response: ''
};
},
methods: {
submit() {
// Send data to server or perform other actions
this.response = 'Data submitted: ' + this.message;
}
}
};
</script>
Livewire Components:
Server-Side Rendering: Livewire components are rendered on the server-side within the Laravel application. They handle user interactions through AJAX requests and update the DOM dynamically.
PHP and Blade Templating: Livewire components are written in PHP and Blade templating engine, allowing developers to use familiar syntax and Laravel features.
Reactivity: Livewire components offer reactivity similar to Vue.js, but the reactivity is managed on the server-side, meaning that changes to the component state trigger server-side actions and DOM updates.
Integration with Laravel: Livewire seamlessly integrates with Laravel ecosystem, including validation, authorization, and routing.
Example:
// Livewire Component Example
class MessageComponent extends Component
{
public $message;
public $response;
public function submit()
{
// Server-side logic (e.g., data validation, database interaction)
$this->response = 'Data submitted: ' . $this->message;
}
public function render()
{
return view('livewire.message-component');
}
}
<!-- Blade Template for Livewire Component -->
<div>
<input wire:model="message">
<button wire:click="submit">Submit</button>
<p>{{ $response }}</p>
</div>
CRUD Coding Example:
Let's illustrate CRUD operations using both Vue.js and Livewire components:
Vue.js CRUD Example:
You would typically make AJAX requests to a server-side API (e.g., built with Laravel) to perform CRUD operations.
Below is an example of a Vue.js component handling CRUD operations:
<!-- Vue.js CRUD Component Example -->
<template>
<div>
<input v-model="name">
<button @click="create">Create</button>
<ul>
<li v-for="item in items" :key="item.id">
{{ item.name }}
<button @click="update(item.id)">Update</button>
<button @click="deleteItem(item.id)">Delete</button>
</li>
</ul>
</div>
</template>
<script>
export default {
data() {
return {
name: '',
items: []
};
},
created() {
// Fetch initial data from server
this.fetchItems();
},
methods: {
fetchItems() {
// Make AJAX request to fetch items from server
},
create() {
// Make AJAX request to create item on server
},
update(id) {
// Make AJAX request to update item on server
},
deleteItem(id) {
// Make AJAX request to delete item on server
}
}
};
</script>
Livewire CRUD Example:
With Livewire, you handle CRUD operations directly in PHP on the server-side within the Livewire component.
Below is an example of a Livewire component handling CRUD operations:
// Livewire CRUD Component Example
class ItemComponent extends Component
{
public $name;
public $items;
public function mount()
{
$this->fetchItems();
}
public function fetchItems()
{
// Fetch items from database
$this->items = Item::all();
}
public function create()
{
// Validate input and create new item
Item::create(['name' => $this->name]);
$this->fetchItems(); // Refresh items list
$this->name = ''; // Clear input field
}
public function update($id)
{
// Validate input and update item
$item = Item::find($id);
$item->update(['name' => $this->name]);
$this->fetchItems(); // Refresh items list
$this->name = ''; // Clear input field
}
public function delete($id)
{
// Delete item
Item::find($id)->delete();
$this->fetchItems(); // Refresh items list
}
public function render()
{
return view('livewire.item-component');
}
}
<div>
<input wire:model="name">
<button wire:click="my">
</div>
in above example write a full coding of vue js crud example
Certainly! Here's a full coding example of a Vue.js CRUD (Create, Read, Update, Delete) component:
<!-- Vue.js CRUD Component Example -->
<template>
<div>
<input v-model="name" placeholder="Enter item name">
<button @click="create">Create</button>
<ul>
<li v-for="item in items" :key="item.id">
{{ item.name }}
<button @click="update(item)">Update</button>
<button @click="deleteItem(item.id)">Delete</button>
</li>
</ul>
</div>
</template>
<script>
import axios from 'axios';
export default {
data() {
return {
name: '',
items: []
};
},
created() {
// Fetch initial data from server
this.fetchItems();
},
methods: {
fetchItems() {
// Make AJAX request to fetch items from server
axios.get('/api/items')
.then(response => {
this.items = response.data;
})
.catch(error => {
console.error('Error fetching items:', error);
});
},
create() {
// Make AJAX request to create item on server
axios.post('/api/items', { name: this.name })
.then(response => {
this.fetchItems(); // Refresh items list
this.name = ''; // Clear input field
})
.catch(error => {
console.error('Error creating item:', error);
});
},
update(item) {
const newName = prompt('Enter new name for item:', item.name);
if (newName !== null) {
// Make AJAX request to update item on server
axios.put(`/api/items/${item.id}`, { name: newName })
.then(response => {
this.fetchItems(); // Refresh items list
})
.catch(error => {
console.error('Error updating item:', error);
});
}
},
deleteItem(id) {
if (confirm('Are you sure you want to delete this item?')) {
// Make AJAX request to delete item on server
axios.delete(`/api/items/${id}`)
.then(response => {
this.fetchItems(); // Refresh items list
})
.catch(error => {
console.error('Error deleting item:', error);
});
}
}
}
};
</script>
In this example:
- We have a Vue.js component with an input field for entering item names, a "Create" button to add new items, and a list to display existing items.
- The fetchItems() method retrieves the list of items from the server when the component is created.
- The create(), update(), and deleteItem() methods make AJAX requests to the server to perform CRUD operations.
- We use Axios, a popular HTTP client for Vue.js, to make HTTP requests to the server API endpoints.
- The server-side API endpoints (/api/items) are expected to handle the CRUD operations accordingly
example of constructor or mount with one stories with respect to real life example
constructor:when account is created first time A bank account object can have a constructor that takes in parameters such as account number, account type, and balance to initialize its state.
person info==name,marks 10th
mount: but we have to check balance regularly basis
person info:salary increment, fetch blog post from db , regularly updated
why this concept came if x-model is there then why x-bind concept came
in black board draw input field and below in label write name just pictorial representation
The concept of wire:bind in Laravel Livewire came as an alternative to wire:model in situations where you want more control over when data is synchronized between the HTML form elements and the Livewire component properties.
While wire:model provides real-time two-way data binding, updating Livewire component properties immediately as the user interacts with the form elements, there are scenarios where this behavior may not be desirable or practical.
Here are some reasons why the wire:bind concept was introduced:
Control over synchronization: With wire:model, changes to form elements are synchronized with Livewire component properties immediately as the user types. In some cases, you may want to delay the synchronization until a certain event occurs, such as form submission. wire:bind gives you more control over when the data is synchronized by deferring updates until explicitly triggered, typically when the form is submitted.
Reduced server requests: In applications with complex forms or a large number of form fields, real-time synchronization with wire:model can lead to frequent server requests as the user types. This may not be optimal for performance, especially in scenarios where the user is expected to make multiple changes before submitting the form. wire:bind allows you to collect all the form data and submit it at once, reducing the number of server requests.
Validation and validation errors: With real-time synchronization using wire:model, Livewire performs validation on form fields as the user types and displays validation errors immediately. While this provides instant feedback to the user, it may not be suitable for all scenarios, especially if you prefer to validate the entire form and display validation errors together. wire:bind allows you to collect all the form data and validate it at once, providing a unified approach to form validation.
Complex data manipulation: In some cases, you may need to perform complex data manipulation or validation on form fields before updating the Livewire component properties. With wire:model, Livewire updates the component properties immediately, making it challenging to intercept and modify the data before it's synchronized. wire:bind allows you to intercept form submissions, manipulate the data as needed, and then update the Livewire component properties accordingly.
In summary, while wire:model provides convenient real-time two-way data binding for interactive forms, wire:bind offers more flexibility and control over data synchronization, making it suitable for scenarios where you need to defer updates or perform additional processing before updating Livewire component properties.
