Quick demo

Use the definition of #[Route(path: 'attr/route', methods: ["get"])], means the same settings were done in your routing configuration:

This library will smartly connect your controller and routing automatically, which means you can access to the hello method in Ci4Controller through the path of /attr/route.

Installation Guide

Requirements

1. CodeIgniter Framework 4
2. Composer
3. PHP8↑

Composer Install

Use Composer to download the library needed dependency under the project root.

Use the library built-in command to initialize the needed files.

The upper command will make to changes on our project.

1. app/Config will have a RouteAttributes.php configuration file, you can adjust the library's execution setting through this file. And it looks like this:

2. Automatically write the library needed events into the endpoint of file app/Config/Events.php, the event will be used when CodeIgniter4 initializes, automatically registering routes. The command will write the contents in as below:

Instructions

In short, this library is a CodeIgniter4 Router presentative way under the PHP8 Attributes feature, it merely provides litte mapping and encapsulation for some CodeIgniter4 Router methods. Other than that, there's no other extra functionalities.

By means of scanning the comments automatically inside the Controller, routes and methods will be connected, enables you to write routing rules straightforwardly, and maintain the relationship between Controllers and Routes in a convenient way.

Production and Development Environment

When you are using this library in Development environment under CodeIgnitere4 framework, it will re-analyze all Controllers classes everytime when a request should occur, and meanwhile handle with the correspond Route Attribures. This strategy can bring maximum convenience to developing, changes of Route Attributes will take effect immediately. However, in production environment, this strategy will cause considerale performance loss. Therefore our library provides a cache-like method to lower the performance loss aiming at production environment.

Configuration File

You can find the two adjustable variables, routeDefinitionFilePath and productionUseDefinitionFile, in app/Config/RouteAttributes.php.

You can use routeDefinitionFilePath to define storage location of your configuration file for production environment, it will be placed at project_root/writable/cache as default.

You can change productionUseDefinitionFile as true or false to define whether to activate Route Attributes definition file in production environment or not to achieve the best performance. If it's false, then on every request of production environment, they will be re-scanned and Route Attributes inside Controllers will be handled.

Generate Route Attribute Definition File

You can generate your Route Attribute Definition File using the command below, to lower the performance loss:

Upper mentioned command will generate a RouteAttributesDefinition file under the path defined in routeDefinitionFilePath.

Update Route Attribute Definition File

There are two ways to update the Route Attributes Definition File for your Production environment

1. Run php spark route-attr:make again, new contents will directly cover the old ones.
2. Delete RouteAttributesDefinition file, if the library couldn't find the file, it will scan and generate a Route Attribute Definition File automatically.

Route

You can register your routes like this:

In this example, Path represents the acutal path to call this Controller method, and method will expect you to pass a String array, including the HTTP verbs to access to this Controller method.

According to the Router Global Options of the CodeIgniter4, you can use the following verbs: add, get, post, put, head, options, delete, path, and cli. You can declare several verbs to achieve the effect of switching between different method under the same path with access to the identical Controller effects.

options

You can pass in options array to make special adjustments to routes, the library won't do any processing or judging to your options, this means you must consult the CodeIgniter4 documentation to write the correct options. Usually, this parameter will be like this:

ignoreGroup

If you are using RouteGroup to configure routes under the same controller uniformly, but wanting to set one of them apart without extending RouteGroup. You can set this parameter to true, making routing an independent job like this:

Placeholder

You only need to concentrate on the placeholder configuration in your path, the library will determine the parameter amount of your controller and finish the correct route settings.

Equals to:

Single Method to declare multiple Routes

If you need, you can also tie several route settings to a single Method.

Through the upper settings, no matter accessing to attr/route or hello/msg, they are all pointing at the same Ci4Controller's hello method.

RouteRESTful

CodeIgniter4 offers convenient RESTful patterns for you to inherit related class to quickly achieve RESTful design pattern. This library also provides related patterns for you to transform your controller into RESTful routes rapidly.

Resource Route

Equals to:

name means the resource name, can also be declared as a path. There are two available options on type, naming resource and presenter.

Presenter Route

You can adjust the value of type to switch RouteRESTful into Presenter Route pattern.

Equals to:

You can adjust RouteRESTful type base on your need, through setting up your ResourceRoute or PresenterRoute.

websafe

This option will be activated only when type adopts resource. It will add websafe =>1 into the route's options to make it available for HTML forms.

only

You can use only option to restrict only generate the route you've mentioned. This parameter only accept one array, composed of method names.

For acceptable method names, please refer to our documentation.

except

You can use except to remove production of some routes, this parameter only accepts one array, composed of method names.

For acceptable method names, please refer to our documentation.

placeholder

If your API needs the resource ID, (:segment) placeholder will be used as default. But you can also pass placeholder parameter to make changes to it:

options

Through passing in the options array to do particular revision aiming at the RESTful routes, the library won't do any judgement to your passed options.

One thing should pay extra attention, if parameters like websafe, only, except, or placeholder were used, then the library will automatically compose the contents you've passed in with the options array. If there's replicated declarations being made, the parameters' content will be focused.

You must refer to the CodeIgniter4 documentation to write the correct options. Usually, the usage if this parameter will look loke this:

ignoreGroup

If you are using RouteGroup to configure routes under the same controller uniformly, but wanting to set one of them apart without extending RouteGroup. You can set this parameter to true:

RouteGroup

Usually, you will wish not to re-configure the duplicated path, such as /api/v1. Hence you can make use of RouteGroup to uniformly apply the same path or options to all routing settings under the class.

Upper settings equals to:

RouteEnvironment

You can create special routes for specified environment, for instance, routes for development will be unavailable in production and staging environment. This requirement can be done through declaring RouteEnvironment in your class.

Upper setting equals to:

If you need, RouteEnvironment can also work with RouteGroup:

Upper setting equals to:
