Optimize Toolset

I’ve always been into building performant and accessible sites, but lately I’ve been taking it extremely seriously. So much so that I’ve been building a tool to help me optimize and monitor the sites that I build to make sure that I’m making an attempt to offer the best experience to those who visit them. If you’re into performant, accessible and SEO friendly sites, you might like it too! You can check it out at Optimize Toolset.

About

Hi, 👋, I’m Ryan Hefner  and I built this site for me, and you! The goal of this site was to provide an easy way for me to check the stats on my npm packages, both for prioritizing issues and updates, and to give me a little kick in the pants to keep up on stuff.

As I was building it, I realized that I was actually using the tool to build the tool, and figured I might as well put this out there and hopefully others will find it to be a fast and useful way to search and browse npm packages as I have.

If you’re interested in other things I’m working on, follow me on Twitter or check out the open source projects I’ve been publishing on GitHub.

I am also working on a Twitter bot for this site to tweet the most popular, newest, random packages from npm. Please follow that account now and it will start sending out packages soon–ish.

Open Software & Tools

This site wouldn’t be possible without the immense generosity and tireless efforts from the people who make contributions to the world and share their work via open source initiatives. Thank you 🙏

swgto-ts

v3.0.0

Published

Generate API request files from OpenAPI 3.x documents.

Readme

swgto

swgto 是一个把 OpenAPI 3.x 文档转换成项目内请求函数的 Node.js 库和 CLI。

安装后会注册一个 swgto 命令。执行时它会在当前目录查找 .swaggerts.config.ts.swaggerts.config.js,然后生成:

  • 按路径前缀分组的请求文件
  • 按文档模块输出请求文件。单文档默认输出到 services/,多文档时多个模块目录平级
  • outputDir/index.tsoutputDir/index.js
  • 类型文件 outputDir/types.ts 或带 JSDoc 的 outputDir/types.js

安装

npm install swgto-ts

配置

在项目根目录创建 .swaggerts.config.ts

import type { SwaggerTsConfig } from 'swgto-ts'

const config: SwaggerTsConfig = {
  docUrls: 'https://example.com/openapi.json',
  httpClientPath: '@/utils/request',
  outputDir: 'src/api',
  outputType: 'ts',
  typeName: 'types',
  cleanOutput: true,
  renameMethod: (apiPath, method) => `${method}_${apiPath.replace(/[\\/{}]/g, '_')}`,
  resolveRequestPath: (apiPath, method) => `/proxy${apiPath}`,
}

export default config

多文档模式下需要提供 moduleName

export default {
  docUrls: ['https://example.com/user-openapi.json', 'https://example.com/order-openapi.json'],
  httpClientPath: '@/utils/request',
  outputDir: 'src/api',
  moduleName: (docUrl) => (docUrl.includes('user') ? 'user' : 'order'),
}

使用

swgto

输出示例

src/api/
  index.ts
  types.ts
  services/
    get_user_list.ts
    post_user_create.ts

配置项

export interface SwaggerTsConfig {
  docUrls: string | string[]
  httpClientPath: string
  renameMethod?: (path: string, method: string) => string
  resolveRequestPath?: (path: string, method: string, docUrl: string) => string
  ignoreUrl?: (path: string, method: string, docUrl: string) => boolean
  outputDir?: string
  moduleName?: (docUrl: string) => string
  outputType?: 'ts' | 'js'
  typeName?: string
  cleanOutput?: boolean
  fileNaming?: 'module' | 'path'
  flattenQueryParam?: boolean
  mergeParams?: boolean
  apiDocs?: ApiDocsConfig
}

字段说明

| 字段 | 类型 | 默认值 | 说明 | | -------------------- | ----------------------------------- | ------------ | -------------------------------------------------------------------------------------------------------------------------------------- | | docUrls | string \| string[] | (必填) | OpenAPI 3.x 文档的 URL,支持单文档字符串或多文档数组 | | httpClientPath | string | (必填) | 项目内 HTTP 请求工具的引入路径,生成的文件会从中 import request | | outputDir | string | 'src/api' | 代码输出目录,相对项目根目录 | | outputType | 'ts' \| 'js' | 'ts' | 输出文件类型,'ts' 生成 .ts 文件,'js' 生成 .js 文件(带 JSDoc 类型注释) | | typeName | string | 'types' | 类型文件名(不含后缀),如 'types' 生成 types.tstypes.js | | fileNaming | 'module' \| 'path' | 'path' | 文件组织方式:'path' 按接口路径每个文件一个函数;'module' 按控制器合并到同一个文件 | | moduleName | (docUrl) => string | 'services' | 多文档时,为每个文档指定模块目录名。多文档模式下必填 | | renameMethod | (path, method) => string | 见说明 | 自定义函数名生成规则。默认根据路径和方法名自动生成(如 get_user_list) | | resolveRequestPath | (path, method, docUrl) => string | 原路径 | 自定义请求路径转换规则,可用于添加统一前缀等,如 (path) => \/proxy${path}` | |ignoreUrl |(path, method, docUrl) => boolean| 不过滤 | 过滤不需要生成代码的接口,返回true跳过当前接口 | |cleanOutput |boolean |false | 生成前是否清空输出目录 | |flattenQueryParam |boolean |false | 当 query 参数只有一个且为$ref引用类型时,直接用引用类型代替{ query: RefType } | |mergeParams |boolean |false | 合并参数层级:true时展平path/query/body嵌套,直接使用params: { field1, field2 }代替params: { path: {...}, query: {...} }| |apiDocs |ApiDocsConfig` | 见说明 | 自动生成 API 文档(HTML/Markdown),详细配置见 API 文档生成 |

函数名生成规则

默认函数名格式为 {method}_{path_segments},如:

  • GET /user/listget_user_list
  • POST /user/createpost_user_create

可通过 renameMethod 自定义:

renameMethod: (path, method) => `${method}_${path.replace(/[\\/{}]/g, '_')}`,

文件组织方式

fileNaming: 'path'(默认)— 每个接口生成独立文件:

src/api/moduleA/
  get_user_list.ts
  post_user_create.ts
  get_user_detail.ts

fileNaming: 'module'— 按控制器合并文件(自动识别 RESTful 资源路径分组):

src/api/moduleA/
  user.ts         // 包含 get_user_list, post_user_create, get_user_detail
  order.ts        // 包含 get_order_list, post_order_create

参数合并模式

mergeParams: true 时展平参数层级,适用于不想嵌套 path/query/body 的场景:

// mergeParams: false(默认),参数按来源嵌套
getUser({ path: { id: '1' }, query: { name: 'foo' } })

// mergeParams: true,参数展平
getUser({ id: '1', name: 'foo' })

API 文档生成

配置 apiDocs 可在生成代码的同时,自动输出一份人类可读的 API 文档:

export default {
  // ... 其他配置
  apiDocs: {
    enable: true,
    format: 'html',           // 'html' 或 'markdown'
    output: 'api-docs.html',  // 输出文件名
    title: '我的 API 文档',    // 文档标题,默认取 OpenAPI info.title
    companyName: 'XX 公司',   // 封面公司名称(仅 HTML)
    template: './my-template.html', // 自定义 HTML 模板路径(仅 HTML)
    theme: './my-theme.css',  // 自定义样式文件路径(仅 HTML)
  },
}

| 配置项 | 类型 | 默认值 | 说明 | | ------------- | --------------------------- | ----------------------- | -------------------------------------------------------------- | | enable | boolean | false | 是否开启文档生成 | | format | 'html' \| 'markdown' | 'html' | 输出格式:HTML 适合浏览器打印为 PDF,Markdown 适合仓库内查看 | | output | string | 'api-docs.html' | 输出文件名,相对 outputDir | | title | string | OpenAPI info.title | 文档标题 | | companyName | string | 无 | 封面上的公司名称(仅 HTML) | | template | string | 内置模板 | 自定义 HTML 模板路径(仅 HTML)。优先级:template 配置 > 项目根目录 .swagger.docs.html > 内置默认模板 | | theme | string | 无 | 自定义 CSS 文件路径,覆盖文档样式(仅 HTML) |

HTML 文档

输出为带书本风格的 HTML 页面,包含:

  • 封面页:A4 整页,显示公司名称(如配置)、API 名称和版本号
  • 目录:方法 + 路径 | 点线 | 摘要,点击跳转到对应接口
  • 接口卡片:包含路径参数、查询参数、请求体、响应体的字段表格(名称 / 类型 / 必填 / 描述)

可通过项目根目录的 .swagger.docs.html 文件自定义文档样式。如果设置了 apiDocs.template,则优先使用该路径的模板文件。

Markdown 文档

输出为 .md 文件,包含:

  • 封面区域:公司名称(如配置)、API 名称和版本号
  • 目录(Table of Contents):所有接口的锚点链接列表
  • 每个接口的详细说明:HTTP 方法 + 路径、描述、参数表格和响应表格

适合直接在代码仓库中查看或用于 GitBook、VuePress 等文档工具。```
