the online package explorer

Runpkg turns a static file into an interactive and informative browsing experience. It lets you navigate any JavaScript package on npm thanks to unpkg.com, a popular and reliable CDN mirror of the npm registry. You can use this tool to learn more about the inner workings of your project's dependencies; find out how modules work, what they depend on, the size of specific imports as well as other useful metadata.

Features

• 🔭 Navigable project directory listing
• 🎨 Syntax highlighted file contents
• 📝 Insights through static analysis

Usage

To view a package or module in the browser with runpkg, prepend any unpkg url with: r. For example:

Source	URL
unpkg	https://unpkg.com/es-react@16.8.30/index.js
runpkg	https://runpkg.com/es-react@16.8.30/index.js

You will be redirected to runpkg which will display the relevant package and file. You can navigate around the package using the 'Package' panel which contains a directory listing. The 'File' tab will also display any information uncovered during static analysis.

Note if browsing a directory then runpkg will ignore the trailing / and take you to the entry point.

Development

See CONTRIBUTING.md for instructions on how to run this project locally, contribute, and to see our code of conduct.

Local URLs

As we're not using Netlify to redirect URLs locally, you have to pass in the package or file part of the request in as a search param. Notice the ? in the local URL. For example:

Source	URL
unpkg	https://unpkg.com/es-react@16.8.30/index.js
localhost	http://localhost:8080/?es-react@16.8.30/index.js
