npm install @jsdocs-io/extractor
!Language
This is the API extractor powering jsDocs.io.
It downloads packages from the npm registry and analyzes them to extract their public API.
- Bun must be installed and available in the PATH to resolve and install packages
- Explore the API on jsDocs.io
- View package contents on unpkg
- View repository on GitHub
- Read the changelog on GitHub
> [!WARNING]
> Analyzing packages is a blocking operation that requires some time, even seconds, to finish!
> Using workers is recommended.
1. Analyze the latest version of the preact package from the npm registry:
``ts
import { getPackageApi } from "@jsdocs-io/extractor";
(async () => {
const packageApi = await getPackageApi({ pkg: "preact" });
console.log(JSON.stringify(packageApi, null, 2));
})();
`
2. Analyze a specific subpath export, like preact/hooks:
`ts
import { getPackageApi } from "@jsdocs-io/extractor";
(async () => {
const result = await getPackageApi({ pkg: "preact", subpath: "hooks" });
console.log(JSON.stringify(packageApi, null, 2));
})();
