API Docs Builder

Generates API reference JSON from TypeScript sources for Video.js 10 components and utilities.

Spec: The E2E test suite at src/tests/e2e.test.ts is the living specification for the builder pipeline. It exercises every input pattern against a mock monorepo and asserts the expected JSON output. Read the test to understand how the builder works.

Architecture

TypeScript Sources (core/html/react/store packages)
         ↓
   api-docs-builder (typescript-api-extractor)
         ↓
   JSON files (component + util references)
         ↓
   Astro components (ComponentReference / UtilReference)
         ↓
   Interactive tables in MDX pages

Usage

Building

The builder runs automatically before dev/build via npm scripts:

# Run manually
pnpm api-docs

# Runs automatically on:
pnpm dev      # via predev hook
pnpm build    # via prebuild hook

In MDX

import ComponentReference from "@/components/docs/api-reference/ComponentReference.astro";
import UtilReference from "@/components/docs/api-reference/UtilReference.astro";

<ComponentReference component="PlayButton" />
<UtilReference util="usePlayer" />
