How to write Composer package

下面由composer教程栏目给大家介绍Composer包的编写，希望对需要的朋友有所帮助！

准备工作

1，有自己的github账号
2，有自己的https://packagist.org 网站的账号

新建一个目录（示例）

laravel
|--src
|  |-composer.php

初始化 composer.json文件

在laravel文件下
 composer init   命令

// 1. 输入项目命名空间
// 注意<vendor>/<name> 必须要符合 [a-z0-9_.-]+/[a-z0-9_.-]+
Package name (<vendor>/<name>) [dell/htdocs]: output/test=
// 2. 项目描述
Description []: 这是一个测试
// 3. 输入作者信息，可以直接回车
Author [, n to skip]:  sinker <2713497141@qq.com>
// 4. 输入最低稳定版本，stable, RC, beta, alpha, dev
Minimum Stability []: dev
// 5. 输入项目类型，
Package Type (e.g. library, project, metapackage, composer-plugin) []: library
// 6. 输入授权类型
License []: MIT
// 7. 输入依赖信息
Would you like to define your dependencies (require) interactively [yes]?
// 如果需要依赖，则输入要安装的依赖
Search for a package: php
// 输入版本号
Enter the version constraint to require (or leave blank to use the latest version): >=5.4.0
// 如需多个，则重复以上两个步骤
// 8. 是否需要require-dev，
Would you like to define your dev dependencies (require-dev) interactively [yes]?

// 操作同上
{
    "name": "output/test",
    "description": "composer",
    "type": "library",
    "license": "MIT",
    "authors": [
        {
            "name": "sinker",
            "email": "2713497141@qq.com"
        }
    ],
    "minimum-stability": "dev",
    "require": {}
}
// 9. 是否生成composer.json
Do you confirm generation [yes]? yes
Would you like the vendor directory added to your .gitignore [yes]?

校验composer.json

composer validate composer.json

添加自动加载 (composer.json)

"autoload": {
        "psr-4": {
            "Composer\\": "src/"
        }
    }

在Composer.php编写逻辑

namespace Composer;   ## 注意点此处要和自动加载出相同

class Test
{
    public function save()
    {
        echo 'composer-test';
    }
}

写完直接提交git

git tag 1.0.0  
git push --tag    打版本号

最后将git地址放到https://packagist.org 官网

提交新本版到仓库 会自动同步到 https://packagist.org
