wiki-infoboxes

Extract Wikipedia article infoboxes as structured JSON — zero runtime dependencies.

As defined by Wikipedia: An infobox is a fixed-format table usually added to the top right-hand corner of articles to consistently present a summary of some unifying aspect that the articles share.

Install

pnpm install wiki-infoboxes

Usage

import { fetchInfoBoxes, fetchSearchInfoBoxes } from 'wiki-infoboxes'

// Exact article title
const data = await fetchInfoBoxes('Anglo-Irish_Treaty')
console.log(data)
// {
//   name:      { text: 'Anglo-Irish Treaty' },
//   long_name: { text: 'Articles of Agreement for a Treaty Between Great Britain and Ireland' },
//   date_signed: { text: '6 December 1921' },
//   …
// }

// Free-text search (uses the top result)
const data2 = await fetchSearchInfoBoxes('republic of ireland')
console.log(data2.common_name.text)  // → 'Ireland'

CommonJS works too:

const { fetchInfoBoxes, fetchSearchInfoBoxes } = require('wiki-infoboxes')

API

fetchInfoBoxes(title, ttl?): Promise<Infobox>

Fetches the infobox for the exact Wikipedia page title.
ttl controls the in-memory cache lifetime in milliseconds (default: 3_600_000 — 1 hour).

fetchSearchInfoBoxes(query, ttl?): Promise<Infobox>

Runs a Wikipedia search for query and returns the infobox of the top result.

clearCache(): void

Invalidates all cached responses (useful in tests).

Types

interface InfoboxValue { text: string }
type Infobox = Record<string, InfoboxValue>

Architecture

The package ships zero runtime dependencies. Functionality previously provided by third-party libraries is reimplemented locally:

| Old dependency | Replaced by | |----------------------|--------------------------------------| | wtf_wikipedia | src/wikitext.ts — infobox parsersrc/wikipedia.ts — MediaWiki API client | | simple-fetch-cache | src/cache.ts — in-memory TTL cache |

The build uses tsup and emits both ESM (dist/index.js) and CJS (dist/index.cjs) bundles with TypeScript declarations.

Development

npm install
npm run build    # compile with tsup
npm test         # run Jest (offline unit tests + integration tests)
