@jsdocs-io/extractor

This is the API extractor powering jsDocs.io.

It downloads packages from the npm registry and analyzes them to extract their public API.

Requirements

• Bun must be installed and available in the PATH to resolve and install packages

API & Package Info

• Explore the API on jsDocs.io
• View package contents on unpkg
• View repository on GitHub
• Read the changelog on GitHub

Usage Examples

[!WARNING] Analyzing packages is a blocking operation that requires some time, even seconds, to finish! Using workers is recommended.

• Analyze the latest version of the preact package from the npm registry:

import { getPackageApi } from "@jsdocs-io/extractor";

(async () => {
  const packageApi = await getPackageApi({ pkg: "preact" });
  console.log(JSON.stringify(packageApi, null, 2));
})();

• Analyze a specific subpath export, like preact/hooks:

import { getPackageApi } from "@jsdocs-io/extractor";

(async () => {
  const result = await getPackageApi({ pkg: "preact", subpath: "hooks" });
  console.log(JSON.stringify(packageApi, null, 2));
})();
