【手把手带你撸一个脚手架】第三步, 获取 github 项目信息

系列文章:

• 【手把手带你撸一个脚手架】第一步, 创建第一个命令
• 【手把手带你撸一个脚手架】第二步, 搭建开发环境
• 【手把手带你撸一个脚手架】第三步, 获取 github 项目信息
• 【手把手带你撸一个脚手架】第四步, 通过撸码获取项目信息
• 【手把手带你撸一个脚手架】第五步, 撸完收工

脚手架, 作为一个工具, 主要是用来搬运我们已经准备好的项目模板(webpack 配置, koa 项目雏形等等), 这一步我们就来创建用于搬运的项目模板. 并通过接口获取相关信息 github Api 文档

ps: 这一步基于 github 若有没使用过的小伙伴, 请加油

创建一个专门用于维护项目模板的项目组

为了不和自己平时写的各种辣鸡代码混杂在一起, 这里我专门创建了一个 organization 不会创建的兄弟们请 度娘

• 目录切换到刚刚创建的 organization 上

2018-11-15-00-38-51

• 创建一个项目

2018-11-15-00-39-18

• 向创建的项目中添加一个文件, 上传到 github 并打好 tag

2018-11-15-00-44-17

准备工作完成 ^_

通过 github 开放 api 获取项目信息

baseUrl: https://api.github.com

作为一个开发工具, 我们需要获取的项目信息包含以下几个:

获取组织所属项目列表文档

我们可以尝试一下获取刚刚创建的 organization 下的项目目录

curl https://api.github.com/orgs/learn-cli-organization/repos

// 返回的结果

拿到这个数组说明我们已经能够获取到项目组中的所有项目啦, 一波猝不及防的商业互吹 ^_

获取指定项目的版本号 文档

通过前一个接口, 我们成功的获取到了项目组中所有的项目信息, 接下来我们可以通过以下接口获取到指定项目的版本信息(就是 tags)

curl https://api.github.com/repos/learn-cli-organization/demo/tags

// 返回结果
[
  {
    "name": "v0.0.1",
    "zipball_url": "https://api.github.com/repos/learn-cli-organization/demo/zipball/v0.0.1",

      "url": "https://api.github.com/repos/learn-cli-organization/demo/commits/00f0dda86e5f922e2ae406c25e19b44b2463f690"
    },
    "node_id": "MDM6UmVmMTU3NTc5Njc0OnYwLjAuMQ=="
  }
]

下集预告: 到目前为止, 我们已经能够获取到项目信息. 下一步我们会将结合 inquirer.js 实现命令行交互式的动态获取这些信息
