Redirect any npm package name to its source repository in one request.

When you visit pkgsource.ffflorian.dev/<packageName>, the server fetches the package metadata from the npm registry, extracts the repository, homepage, or url field, normalizes the URL (handling git+, git://, and ssh:// variants), and issues an HTTP redirect to the resolved source.

Visit pkgsource.ffflorian.dev/{packageName} in your browser, e.g. pkgsource.ffflorian.dev/nock.

Visit pkgsource.ffflorian.dev/{@scope}/{packageName}, e.g. pkgsource.ffflorian.dev/@nestjs/core.

Append @{version} to the package name, e.g.:

• pkgsource.ffflorian.dev/[email protected]
• pkgsource.ffflorian.dev/typescript@beta

If no version is specified, the latest version is used.

Add ?raw to get a JSON response instead of a redirect, e.g. pkgsource.ffflorian.dev/commander?raw.

{"code": 200, "url": "https://github.com/tj/commander.js"}

Add ?unpkg to redirect to the package's file tree on unpkg.com, e.g. pkgsource.ffflorian.dev/[email protected]?unpkg. Combine with ?raw to get the unpkg URL as JSON.
