如何運行Composer.json文件中定義的腳本？ （作曲家Run-Script）

你可以通過composer run-script 命令運行在composer.json 中定義的腳本，使用格式為composer run-script ，例如composer run-script start-server；也可以使用簡寫形式composer run ；若要列出所有可用腳本，可直接輸入composer run-script；若需傳遞參數，則在腳本名稱後加上-- 再接參數，如composer run-script run-task -- --env=dev；若要跳過開發依賴，可添加--no-dev 標誌，如composer run-script test-suite --no-dev。

You can run a script defined in your composer.json file using the composer run-script command followed by the script name. This is useful for executing custom PHP scripts, running tests, or performing build tasks.

Here's how to use it effectively:

Basic Usage: Running a Script

To execute a script, just type:

 composer run-script <script-name>

For example, if you have a script called start-server , you'd run it with:

 composer run-script start-server

This tells Composer to look inside the "scripts" section of your composer.json and run whatever command is associated with that key.

If you want a shortcut, you can also use:

 composer run <script-name>

Which does exactly the same thing.

Listing Available Scripts

If you're not sure what scripts are available, you can list them quickly:

 composer run-script

This will show all the defined scripts in your composer.json . It's especially helpful when working on a new project or collaborating with others.

Alternatively, you can check the "scripts" block directly in your composer.json file.

Passing Arguments to Scripts

Sometimes your script expects arguments — like environment flags or options. You can pass those using -- after the script name:

For example, if your script looks like this:

 "scripts": {
    "run-task": "php bin/task.php"
}

And you want to pass an argument like --env=dev , do this:

 composer run-script run-task -- --env=dev

The part after -- gets passed directly to the underlying command.

⚠️ Note: Make sure the original command supports handling these arguments. Not every script is built to accept extra input.

Running Scripts with Dev Dependencies

By default, Composer runs scripts even if the dependencies are only listed under "require-dev" . But if you're deploying to production or want to skip dev tools, you can add the --no-dev flag:

 composer run-script test-suite --no-dev

This ensures the script doesn't rely on packages that aren't meant for production.

So, whether you're running tests, building assets, or triggering custom logic, composer run-script gives you a clean and flexible way to manage execution flow in your project.基本上就這些。
