Wiki Saikou

SUPER COOL api package for MediaWiki

- 同时兼容浏览器&Node.js 环境 -
- Support both browser and Node.js environment -

本库提供了与原版 new mw.Api() 非常相似的 api 请求封装。让你在非 MediaWiki 环境中轻松实现各种 wiki 操作。使用 TypeScript 编写~
The library provides the out of box accessing to MediaWiki API in both browsers & Node.js, and the syntax is very similar to vanilla new mw.Api(). TypeScript definition included~

特色功能 Features

• Similar API to the vanilla new mw.Api()
• Parameter Schema automatic compliance: { "foo": ["bar", "baz"], watch: false } → { "foo": "bar|baz" }
• Token caching and retry mechanism
• TypeScript support
• With unit tests
• User authentication supports out of the box *(also applicable to Node.js!)

开箱即用 Out of box

通过 NPM 包安装 Installa via NPM

# Via pnpm:
pnpm add wiki-saikou
# Yarn? sure:
yarn add wiki-saikou
# Or just npm:
npm install wiki-saikou

Then, import it to your project:

在浏览器中直接使用 Use directly in the browser

<!-- Method 1: Using ES Module (recommended) -->
<script type="module">
  import { MediaWikiApi } from 'https://esm.run/wiki-saikou'
  const api = new MediaWikiApi('https://zh.moegirl.org.cn/api.php')
  // ...
</script>

<!-- Method 2: Using UMD bundle -->
<script src="https://cdn.jsdelivr.net/npm/wiki-saikou/lib/index.umd.js"></script>
<script>
  const { MediaWikiApi } = window.WikiSaikou
  const api = new MediaWikiApi('https://zh.moegirl.org.cn/api.php')
  // ...
</script>

<!-- Method 3: Using import maps (experimental) -->
<script type="importmap">
  {
    "imports": {
      "wiki-saikou": "https://esm.run/wiki-saikou"
    }
  }
</script>
<script type="module">
  import { MediaWikiApi } from 'wiki-saikou'
  const api = new MediaWikiApi('https://zh.moegirl.org.cn/api.php')
  // ...
</script>

Deno via CDN

import { MediaWikiApi } from 'https://esm.run/wiki-saikou/node'
const api = new MediaWikiApi('https://zh.moegirl.org.cn/api.php')
// ...

使用方法 Usage

You can find sample code snippets in unit test folder.

It's similar to the new mw.Api().

入口文件 Entry file

// automatically imports the correct entry file based on the environment
import { MediaWikiApi } from 'wiki-saikou'
// specify the entry file manually
import { MediaWikiApi } from 'wiki-saikou/node'
import { MediaWikiApi } from 'wiki-saikou/browser'

Constructor

new MediaWikiApi(config: WikiSaikouInitConfig)

interface WikiSaikouConfig {
  /**
   * @default undefined // required in Node.js environment
   * @default `${wgServer}${wgScriptPath}/api.php` // in MW pages
   * @description The MediaWiki API endpoint, e.g. "https://www.mediawiki.org/w/api.php"
   * @optional In real MediaWiki browser pages, `baseURL` can be omitted and will be inferred automatically based on `window.mw`
   */
  baseURL: string
  /**
   * Transport/runtime options passed to the underlying Fexios instance (headers, fetch, credentials, etc.).
   * @default { responseType: 'json' }
   */
  fexiosConfigs: Partial<FexiosConfigs>
  /**
   * Default query parameters merged into every request.
   * @default { action: 'query' }
   */
  defaultParams: MwApiParams
  /**
   * When true, responses whose JSON body contains `error`/`errors` will throw `MediaWikiApiError` even if HTTP status is 2xx.
   * @default false
   */
  throwOnApiError: boolean
}

Deprecated (for backward compatibility):

new MediaWikiApi(baseURL: string, options?: Partial<FexiosConfigs>, defaultParams?: MwApiParams)

Core requests

• get<T = any>(query: MwApiParams, options?: Partial<FexiosRequestOptions>): Promise<FexiosFinalContext<MwApiResponse<T>>>

  • Performs a GET request. query will be merged with config.defaultParams.

• post<T = any>(body: MwApiParams | URLSearchParams | FormData, options?: Partial<FexiosRequestOptions>): Promise<FexiosFinalContext<MwApiResponse<T>>>

  • Performs a POST request. Body and query are normalized to API-friendly formats.

• postWithToken<T = any>(tokenType: MwTokenName, body: MwApiParams, options?: { tokenName?: string; retry?: number; noCache?: boolean }): Promise<FexiosFinalContext<MwApiResponse<T>>>

  • Performs a POST request with a token.
  • tokenType: The type of token to use.
  • body: The body of the request.
  • options: The options for the request.
    • tokenName: The name of the token to use.
    • retry: The number of times to retry the request.
    • noCache: Whether to cache the token.
  • This method will manage the token cache and retry logic automatically.

Authentication

Node.js only:

• login(lgname: string, lgpassword: string, params?: MwApiParams, postOptions?: { retry?: number; noCache?: boolean }): Promise<{ result: 'Success' | 'NeedToken' | 'WrongToken' | 'Failed'; token?: string; reason?: { code: string; text: string }; lguserid: number; lgusername: string }>
  • Login with bot password. Throws WikiSaikouError(LOGIN_FAILED) if result is not Success.

Browser only:

• clientLogin(username: string, password: string, params?: ClientLoginOptions): Promise<{ status: "PASS"; username: string; }>;
  • Login with regular username & password. Throws WikiSaikouError(LOGIN_FAILED) if status is not PASS.

实用工具 Useful helpers

FexiosSaikou

A pre-configured Fexios instance with MediaWiki-friendly defaults:

• MediaWiki-specific request/response params normalization
• built-in token management
• error handling

MwParamNormalizer

MwParamNormalizer is a utility class that helps normalize MediaWiki API parameters.

import { MwParamNormalizer } from 'wiki-saikou'

MwParamNormalizer.normalizeBody({
  string: 'foo',
  number: 123,
  boolean: true,
  falsy: false,
  undefined: undefined,
  null: null,
  array: ['foo', 'bar'],
  file: new Blob(['file contents'], { type: 'text/plain' }),
})
// Result:
/**
 * FormData
 * string=foo
 * number=123
 * boolean=1
 * array=foo|bar
 * file=[Blob]
 */

错误处理 Errors and types

Important

WikiSaikou will NOT throw errors for these situations by default:

1. non-2xx HTTP status codes
2. MediaWiki API responses containing error or errors field

You should handle these situations manually by checking the response context.

• WikiSaikouError
  • Transport/network failures (e.g., fetch failure, HTTP layer issues)
  • SDK behavioral errors such as exhausted internal retries or misconfigurations
  • Note: When MediaWiki API responds with JSON containing error/errors, a MediaWikiApiError should be thrown instead
• WikiSaikouErrorCode
  • Enum of error codes used in WikiSaikouError

Note

If you set options.throwOnApiError = true when constructing MediaWikiApi, then WikiSaikou will handle MediaWiki API errors automatically by throwing MediaWikiApiError for you.

• MediaWikiApiError
  • fetch succeeded but JSON includes error or errors.length > 0
  • Special states (e.g., login NeedToken/WrongToken) are also considered API-side errors
  • Note: network/retry issues belong to WikiSaikouError, not this class

浏览器专属 Browser only

Besides MediaWikiApi, the browser bundle also provides MediaWikiForeignApi which presets CORS-friendly defaults for cross-origin API access.

• new MediaWikiForeignApi(config: WikiSaikouInitConfig)
  • Defaults credentials: 'include', mode: 'cors', and injects origin automatically based on location.origin.

Example:

import { MediaWikiForeignApi } from 'wiki-saikou/browser'
const api = new MediaWikiForeignApi({
  baseURL: 'https://commons.wikimedia.org/w/api.php',
})
