Laravel development: How to use Laravel Swagger to generate API documentation?
When developing web applications, working with API documentation is often a tedious but essential task. Use Swagger to automatically generate and visualize API documentation. In Laravel development, we can use the Laravel Swagger extension package to easily generate Swagger API documentation. This article will guide you on how to use Laravel Swagger with Laravel.
- Install Laravel Swagger
Use Composer to install the Laravel Swagger extension package:
composer require darkaonline/l5-swagger
- Configure Laravel Swagger
Laravel Swagger depends on Swagger UI, so we need to publish the resources of Swagger UI to Laravel's public directory. Use the following command to complete the publishing:
php artisan vendor:publish --provider "L5SwaggerL5SwaggerServiceProvider"
After executing the publishing command, it will be in public/ You can see the swagger-ui directory under the vendor directory. This directory contains all the resources of Swagger UI.
Next, add the following lines to Laravel’s configuration file config/app.php:
'providers' => [
...
L5SwaggerL5SwaggerServiceProvider::class,
],
'aliases' => [
...
'Swagger' => L5SwaggerFacadesL5Swagger::class,
],- Add Swagger comments
In order to tell Laravel Swagger that there is no inferred API format, we need to add Swagger annotations to the code. These annotations allow Laravel Swagger to automatically parse your API and generate corresponding documentation.
/**
* @OAGet(
* path="/users",
* operationId="getUsersList",
* tags={"Users"},
* summary="Get list of registered users",
* description="Returns list of users",
* @OAResponse(response="200", description="successful operation"),
* @OAResponse(response=401, description="Unauthorized"),
* @OAResponse(response=403, description="Forbidden"),
* @OAResponse(response=404, description="Not Found"),
* @OAResponse(response=500, description="Internal Server Error")
* )
*/In the above example, we use the @OAGet annotation to indicate that this is a GET request. path The annotation defines the path to the API. The tags and summary comments are used to display summaries and tags in Swagger documents. Finally, the @OAResponse annotation exemplifies possible response states.
- View Swagger documentation in Laravel
After completing all the previous steps, we can use the following URL to view the Laravel Swagger documentation:
http://your-app.dev/api/documentation
(Please note that if you are using Laravel 5.4 or above, you do not need to define .dev, please use .test or other local domain name instead)
Start Laravel's development server and access the URL above. You should be able to see the automatically generated Swagger documentation in your browser.
In the Swagger documentation, you can view the defined API, test the API based on Swagger annotations added to the API, and view possible response states.
Summary
In this article, we learned how to easily generate Swagger API documentation using the Laravel Swagger extension package. First, we installed Laravel Swagger, then started Swagger and added Swagger annotations to the API. Finally, we looked at the documentation generated by Laravel Swagger.
Using Laravel Swagger can greatly reduce the burden of manually writing API documentation and avoid possible errors and inconsistencies. By using Swagger UI, we can more easily view and test the API, while providing a developer-friendly interface.

How to set environment variables in PHP environment Description of adding PHP running environment variables
Jul 25, 2025 pm 08:33 PM
There are three main ways to set environment variables in PHP: 1. Global configuration through php.ini; 2. Passed through a web server (such as SetEnv of Apache or fastcgi_param of Nginx); 3. Use putenv() function in PHP scripts. Among them, php.ini is suitable for global and infrequently changing configurations, web server configuration is suitable for scenarios that need to be isolated, and putenv() is suitable for temporary variables. Persistence policies include configuration files (such as php.ini or web server configuration), .env files are loaded with dotenv library, and dynamic injection of variables in CI/CD processes. Security management sensitive information should be avoided hard-coded, and it is recommended to use.en
How to make PHP container support automatic construction? Continuously integrated CI configuration method of PHP environment
Jul 25, 2025 pm 08:54 PM
To enable PHP containers to support automatic construction, the core lies in configuring the continuous integration (CI) process. 1. Use Dockerfile to define the PHP environment, including basic image, extension installation, dependency management and permission settings; 2. Configure CI/CD tools such as GitLabCI, and define the build, test and deployment stages through the .gitlab-ci.yml file to achieve automatic construction, testing and deployment; 3. Integrate test frameworks such as PHPUnit to ensure that tests are automatically run after code changes; 4. Use automated deployment strategies such as Kubernetes to define deployment configuration through the deployment.yaml file; 5. Optimize Dockerfile and adopt multi-stage construction
What is Configuration Caching in Laravel?
Jul 27, 2025 am 03:54 AM
Laravel's configuration cache improves performance by merging all configuration files into a single cache file. Enabling configuration cache in a production environment can reduce I/O operations and file parsing on each request, thereby speeding up configuration loading; 1. It should be enabled when the application is deployed, the configuration is stable and no frequent changes are required; 2. After enabling, modify the configuration, you need to re-run phpartisanconfig:cache to take effect; 3. Avoid using dynamic logic or closures that depend on runtime conditions in the configuration file; 4. When troubleshooting problems, you should first clear the cache, check the .env variables and re-cache.
Explain Laravel Eloquent Scopes.
Jul 26, 2025 am 07:22 AM
Laravel's EloquentScopes is a tool that encapsulates common query logic, divided into local scope and global scope. 1. The local scope is defined with a method starting with scope and needs to be called explicitly, such as Post::published(); 2. The global scope is automatically applied to all queries, often used for soft deletion or multi-tenant systems, and the Scope interface needs to be implemented and registered in the model; 3. The scope can be equipped with parameters, such as filtering articles by year or month, and corresponding parameters are passed in when calling; 4. Pay attention to naming specifications, chain calls, temporary disabling and combination expansion when using to improve code clarity and reusability.
PHP development user permission management monetization PHP permission control and role management
Jul 25, 2025 pm 06:51 PM
User permission management is the core mechanism for realizing product monetization in PHP development. It separates users, roles and permissions through a role-based access control (RBAC) model to achieve flexible permission allocation and management. The specific steps include: 1. Design three tables of users, roles, and permissions and two intermediate tables of user_roles and role_permissions; 2. Implement permission checking methods in the code such as $user->can('edit_post'); 3. Use cache to improve performance; 4. Use permission control to realize product function layering and differentiated services, thereby supporting membership system and pricing strategies; 5. Avoid the permission granularity is too coarse or too fine, and use "investment"

How to build a log management system with PHP PHP log collection and analysis tool
Jul 25, 2025 pm 08:48 PM
Select logging method: In the early stage, you can use the built-in error_log() for PHP. After the project is expanded, be sure to switch to mature libraries such as Monolog, support multiple handlers and log levels, and ensure that the log contains timestamps, levels, file line numbers and error details; 2. Design storage structure: A small amount of logs can be stored in files, and if there is a large number of logs, select a database if there is a large number of analysis. Use MySQL/PostgreSQL to structured data. Elasticsearch Kibana is recommended for semi-structured/unstructured. At the same time, it is formulated for backup and regular cleaning strategies; 3. Development and analysis interface: It should have search, filtering, aggregation, and visualization functions. It can be directly integrated into Kibana, or use the PHP framework chart library to develop self-development, focusing on the simplicity and ease of interface.
How to implement a referral system in Laravel?
Aug 02, 2025 am 06:55 AM
Create referrals table to record recommendation relationships, including referrals, referrals, recommendation codes and usage time; 2. Define belongsToMany and hasMany relationships in the User model to manage recommendation data; 3. Generate a unique recommendation code when registering (can be implemented through model events); 4. Capture the recommendation code by querying parameters during registration, establish a recommendation relationship after verification and prevent self-recommendation; 5. Trigger the reward mechanism when recommended users complete the specified behavior (subscription order); 6. Generate shareable recommendation links, and use Laravel signature URLs to enhance security; 7. Display recommendation statistics on the dashboard, such as the total number of recommendations and converted numbers; it is necessary to ensure database constraints, sessions or cookies are persisted,
