How to render views using Blade template engine in Laravel framework

Overview:
Laravel is a popular PHP framework that provides powerful features and tools to quickly develop web applications. One of the important features is the Blade template engine, which helps developers render views as easily as possible.

Blade template engine is the default template engine provided by Laravel. It combines concise syntax and powerful functions to make view rendering simple and flexible. This article will introduce how to use the Blade template engine to render views in the Laravel framework and provide some code examples.

Step 1: Create a view file
First, we need to create a view file that will contain the HTML code we want to render. In the Laravel framework, view files are stored in the resources/views directory by default. Let us create a file named hello.blade.php in this directory:

<!DOCTYPE html>
<html>
<head>
    <title>Hello World</title>
</head>
<body>
    <h1 id="Hello-name">Hello, {{ $name }}</h1>
</body>
</html>

The above code defines a simple HTML page with the page title "Hello World", And uses the syntax of the Blade template engine to display the value of a variable $name. Note that we use double curly braces {{ }} to enclose variables.

Step 2: Routing settings
Next, we need to set up a route to call the view file. In the Laravel framework, the routing file is located at routes/web.php. Let us add a route to this file:

Route::get('/hello/{name}', function ($name) {
    return view('hello', ['name' => $name]);
});

The above code defines a route for a GET request. When /hello/{name} is accessed, an anonymous function will be executed. And pass the routing parameter name to the function. The function uses the view function to render the hello.blade.php view and passes the $name variable to the view.

Step 3: Render the view
Once the routing is set up, we can access /hello/{name} in the browser to render the view. The Laravel framework will find the corresponding view file and render it based on the routing settings. In the above example, the hello.blade.php view will be rendered and the value of the $name variable will be replaced with the corresponding position in the view.

For example, when we access /hello/John, the Laravel framework will render the following HTML code:

<!DOCTYPE html>
<html>
<head>
    <title>Hello World</title>
</head>
<body>
    <h1 id="Hello-John">Hello, John</h1>
</body>
</html>

John## in the above example # will be replaced at the {{ $name }} position in the view.

Summary:

In this article, we learned how to render views using the Blade template engine in the Laravel framework. We created a simple view file that uses the syntax of the Blade template engine to display variables. Then we set up a route to render the view into the browser. Through this simple example, we can see the powerful functions and concise syntax of the Laravel framework and Blade template engine, making view rendering more flexible and easy to understand.

Hope this article can help you understand how to use the Blade template engine to render views in the Laravel framework. I wish you success in developing web applications using the Laravel framework!

You should care about DependencyInjection(DI) because it makes your code clearer and easier to maintain. 1) DI makes it more modular by decoupling classes, 2) improves the convenience of testing and code flexibility, 3) Use DI containers to manage complex dependencies, but pay attention to performance impact and circular dependencies, 4) The best practice is to rely on abstract interfaces to achieve loose coupling.

Select DependencyInjection (DI) for large applications, ServiceLocator is suitable for small projects or prototypes. 1) DI improves the testability and modularity of the code through constructor injection. 2) ServiceLocator obtains services through center registration, which is convenient but may lead to an increase in code coupling.
