  • 💡 Support plug-in development.
  • 🐣 Built-in transformation languages:
    • TypeScript, almost equivalent to handwriting. Depends on axios, wx.request, fetch.

      xhr/ajax、ofetch planned

输出文件

Existing Project

Assume a project directory is:

.
├── src
│   └── apis # Copy the shared directory here.
│       └── shared
│       └── xxx.ts # Other files.

Axios

  1. Find the directory of outDir, copy the entire shared directory to the directory of the axios module you encapsulated.

  2. Open the shared > axios > index.ts file, copy the request method, and add it to the axios module you encapsulated. If it is not encapsulated, copy the index.ts file as a new file to avoid the problem of modification being overwritten.

  3. Taking Vue as an example, add the following code to the main.ts file:

import { createApiClient } from './apis/shared/fetchRuntime';

createApiClient({
  baseURL: 'https://api.xxx.com'
  // onError(msg) {
  //   // 处理错误信息
  // }
})

Wechat

  1. Find the directory of outDir, copy the entire directory of shared to the directory of the wechat module you encapsulated.

  2. Open the shared > wechat > ​​index.ts file, copy the request method, and add it to the wx.request code file you encapsulated. If it is not encapsulated, copy the index.ts file as a new file to avoid the problem of modification being overwritten.

  3. Add the following code to the app.ts file:

import { createApiClient } from './apis/shared/fetchRuntime';
// import Notify from './miniprogram_npm/@vant/weapp/notify/notify';

App<IAppOption>({
  onLaunch() {
    createApiClient({
      baseURL: 'https://api.xxx.com,
      onError(msg) {
        // Notify({ type: 'danger', message: msg, selector: '#v-notify'})
      }
    })
  }
});

Options

Option Alias Type Default Description
url string Swagger/OpenApi/Apifox document address, or local path.
outDir o string ./stc_out Output Directory.
platform p string axios Platform, optional values: axios, wechat. Will be deprecated soon, please use client.
client string axios http request client. When lang is ts/js, the possible values ​​are: axios, wechat, fetch.
lang l string ts Language, used for output file suffix.
tag number Specify the tag from the interface url. By default, the first tag is read for the file name.
filter f string[] Filter interfaces. Interfaces that meet the filter conditions will be generated. Example: --filter "/pet/*", generate an interface for /pet, and support multiple --filter
conjunction c string By The method’s connector, the default value is By.
version v boolean Output version information.
help h boolean Output help information.

Plug-in development

For convenience, STC can not only develop plugins in Deno, but also provides @loongwoo/stc npm library, which can develop plugins in Node environment.

examples

Deno

⚠️ Prepare the Deno environment.

Create a myPlugin.ts file:

// 引用模块
// import { start } from 'https://deno.land/x/stc@2.3.0/mod.ts'
import { start } from 'jsr:@loongwoo/stc@^2.3.0'

// Defining plugins
const myPlugin: IPlugin = {
  name: 'stc:MyPlugin',
  lang: 'ts',
  setup(options) {
    console.log(options)
  },
  onTransform(def, action) {
    // definition
    const defContent: string = parserDefinition(
      def
    )
    // action
    const actionContent: Map<string, string> = parserAction(
      action
    )

    return {
      definition: {
        filename: '_types.ts',
        content: defContent,
      },
      action: actionContent // Here actionContent is of type Map<string, string>, key is the file name, value is the converted code.
    }
  },
  onEnd() {
    console.log('end')
  }
}

// 使用插件
start({
  // ...其他配置
  plugins: [myPlugin]
})

Node

  1. Create a myPlugin.ts file.

  2. Add the @loongwoo/stc reference and use the start method:

import { start } from '@loongwoo/stc'
  1. Implement the code that converts definition and action into the target language in the plugin’s onTransform hook function.
export const myPlugin: IPlugin = {
  name: 'stc:MyPlugin',
  lang: 'ts',
  setup(options) {
    console.log(options)
  },
  onTransform(def, action) {
    // definition
    const defContent: string = parserDefinition(
      def
    )
    // action
    const actionContent: Map<string, string> = parserAction(
      action
    )

    return {
      definition: defContent,
      action: actionContent
    }
  },
  onEnd() {
    console.log('end')
  }
}

4.In the start method, add plugins:

start({
  // ...other options
  plugins: [myPlugin]
})
