Init 命令

init命令是初始化Serverless项目的脚手架。

命令解析

当执行s init -h之后，可以进行相关帮助信息的查看：

$ s init -h
Usage: s init [options]

Initialize a new project based on a template. You can initialize the application that conforms to the serverless devs project specification through GitHub, or you can initialize the application provided by the source by configuring the source.

Example:
    $ s init
    $ s init <project> 
    $ s init <project> -d my_dir
    $ s init <project> --app-name my-express
    $ s init <project> --parameters '{"serviceName":"websiteService"}'
    $ s init [email protected]:foo/bar.git
    $ s init https://github.com/foo/bar.git

Options:
  -d, --dir <dir>                 Where to output the initialized app into (default: ./<ProjectName> )
  -r, --registry <url>            Use specify registry
  --uri <uri>                     Use specify uri, Eg: remote url, local dir, local zip file
  -y                              Assume that the answer to any question which would be asked is yes
  --parameters <parameters>       Initialize with custom parameters
  --app-name <appName>            Modify default Application name
  --no-overwrite                  Only overwrite files with the same name
  -h, --help                      Display help for command

参数解析

参数全称 参数缩写 默认取值 参数含义
dir d ./<ProjectName> 项目初始化的路径/目录
registry -r http://registry.devsapp.cn/simple 源配置地址，类似于Python中指定pip源，或者Node.js中指定NPM源
uri - - 远程或本地文件的地址
- y - 所有问题都默认选择yes
parameters {"serviceName":"websiteService"} 初始化参数
appName my-express 应用/项目名称
no-overwrite - - 只覆盖同名文件，不删除其他文件

初始化项目

引导式初始化

通过s init可以直接进入项目初始化的引导模块：

$ s init

🚀  More applications: https://registry.serverless-devs.com
? Hello Serverless for Cloud Vendors (Use arrow keys or type to search)
❯ Alibaba Cloud Serverless 
  AWS Cloud Serverless 
  Tencent Cloud Serverless 
  Huawei Cloud Serverless 
  Baidu Cloud Serverless 
  Dev Template for Serverless Devs

此时只需要选择对应的选项，按照引导进行操作，即可。例如选择Alibaba Cloud Serverless，就可以看到阿里云Serverless产品下的应用模板分类:

? Hello, serverlesser. Which template do you like? (Use arrow keys or type to search)
❯ Quick start [Deploy a Hello World function to FaaS] 
  Custom runtime example [Deploy function to FaaS with custom runtime] 
  Container example [Deploy function to FaaS with custom-container] 
  Custom domain example [Deploy function to FaaS with custom domain]

此时可以继续选择某分类下的具体应用进行初始化，例如选择Quick start之后，可以看到该分类下的具体模板应用：

? Which template do you like? (Use arrow keys or type to search)
❯ Node.js 
  Python3 
  Java 
  Go 
  Dotnet 
(Move up and down to reveal more choices)

选择Node.js即可完成创建：

$ s init

直接初始化

通过s init [name | url]，可以从配置的Registry或者指定的仓库Url获取模板项目。

初始化Registry应用

以默认的Registry为例，可以初始化相对应的案例项目：start-fc-http-nodejs12，可以通过s init start-fc-http-nodejs12命令来进行：

$ s init start-fc-http-nodejs12

? Please input your project name (init dir) start-fc-http-nodejs12

初始化仓库应用

以Github仓库 https://github.com/devsapp/start-fc 为例，可以通过s init https://github.com/devsapp/start-fc.git命令初始化该案例项目：

$ s init https://github.com/devsapp/start-fc.git
