建立自己的package

參考：

https://rivsen.github.io/post/how-to-publish-package-to-packagist-using-github-and-composer-step-by-step

一、建立資料夾
專案根目錄 / packages / github的帳號 / package名稱 / src

二、在packages 目錄下，新增composer.json

composer.json


{
    "name": "wangchifu/test_page",
    "description": "this is a test for composer.",
    "license": "MIT",
    "authors": [
        {
          "name": "wangchifu",
          "email": "wangchifu@gmail.com"
        }
    ],
    "autoload": {
          "Wangchifu\\Test_page\\": "src/"
    },
    "require": {}
}


三、修改本地專案下的composer.json


...
    "autoload": {
        "classmap": [
            "database"
        ],
        "psr-4": {
            "App\\": "app/",
            "Wangchifu\\Test_package\\": "packages/wangchifu/test_package/src/"
        }
    },
...
