# STC
STC (Swagger Transform Code) is a tool for converting OpenApi/Swagger/Apifox into code.
[](https://github.com/long-woo/stc/actions/workflows/npm.yml)
[](https://jsr.io/@lonu/stc)
## Features
> 🚧 Encapsulate the "shared" directory.
- 🐹 Support for **Swagger 2/3(OpenApi)** and **Apifox**.
- 💡 Support plug-in development.
- 🐣 Built-in transformation languages:
- **TypeScript**, almost equivalent to handwriting. Depends on **`axios`, `wx.request`, `fetch`**.
> `xhr/ajax、ofetch` planned
- **JavaScript**, from TypeScript to it.
- **Dart**, dependency on **`dio`**.
- 🚧 **Swift** ...
## Quick start
### Download executable files
[download](https://github.com/long-woo/stc/releases) by system：
- stc: Intel-based Mac
- stc-m: M-series Mac
- stc-linux：Linux
- stc-win.exe: Windows
### NPM
1.Install the `@lonu/stc` npm package.
```sh
pnpm add @lonu/stc -D
```
2.Open the project's `package.json` file and add the following command to `scripts`:
```json
{
"scripts": {
"api": "stc --url=http://127.0.0.1:4523/export/openapi/2?version=3.1"
}
}
```
### Use
⚠️ Note: deno will not parse the `~` character as the user's home directory.
```sh
stc --url=https://petstore3.swagger.io/api/v3/openapi.json --outDir=out
```
### 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:
```ts
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:
```ts
import { createApiClient } from './apis/shared/fetchRuntime';
// import Notify from './miniprogram_npm/@vant/weapp/notify/notify';
App({
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. |
| 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`. For more usage information, please refer to [micromatch](https://github.com/micromatch/micromatch) |
| conjunction | c | string | By | The method's connector, the default value is `By`. |
| actionIndex | | number | -1 | The method name index, the default value is `-1`. |
| shared | | boolean | true | Whether to generate the shared directory. [default: true]. |
| clean | | boolean | true | Whether to clean the output directory before generating. [default: true]. |
| globalHeader | gh | string[] | | Global header key configuration, multiple can be set. When a single API has the same key, it will not appear as a parameter. |
| 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 `@lonu/stc` npm library, which can develop plugins in Node environment.
[examples](https://github.com/long-woo/stc/tree/master/examples)
### Deno
⚠️ Prepare the [Deno](https://github.com/denoland/deno#install) environment.
Create a `myPlugin.ts` file:
```ts
// 引用模块
// import { start } from 'https://deno.land/x/stc@2.16.1/mod.ts'
import { start } from 'jsr:@lonu/stc@^2.16.1'
// Defining plugins
const myPlugin: IPlugin = {
name: 'stc:MyPlugin',
lang: 'ts',
setup(context: IPluginContext) {
// type map
return {
}
},
onTransform(def, action) {
// definition
const defContent: string = parserDefinition(
def
)
// action
const actionContent: Map = parserAction(
action
)
return {
definition: {
filename: '_types.ts',
content: defContent,
},
action: actionContent // Here actionContent is of type Map, key is the file name, value is the converted code.
}
},
onEnd() {
console.log('end')
}
}
// use plugin
start({
// ...other options
plugins: [myPlugin]
})
```
### Node
1. Create a `myPlugin.ts` file.
2. Add the `@lonu/stc` reference and use the `start` method:
```ts
import { start } from '@lonu/stc'
```
3. Implement the code that converts `definition` and `action` into the target language in the plugin's `onTransform` hook function.
```ts
export const myPlugin: IPlugin = {
name: 'stc:MyPlugin',
lang: 'ts',
setup(context: IPluginContext) {
// type map
return {
}
},
onTransform(def, action) {
// definition
const defContent: string = parserDefinition(
def
)
// action
const actionContent: Map = parserAction(
action
)
return {
definition: defContent,
action: actionContent
}
},
onEnd() {
console.log('end')
}
}
```
4.In the `start` method, add `plugins`:
```ts
start({
// ...other options
plugins: [myPlugin]
})
```
