How it works

pptr.dev doesn't have any server side part. All the data is fetched dynamically from NPM and GitHub via XHRs.

On the first load, pptr.dev:

• fetches puppeteer releases from NPM
• fetches docs/api.md for every release
• caches all the loaded data locally

On a subsequent load, pptr.dev occasionally invalidates cached documentation and releases.

Building and Running

1. To run debug version, use npm run serve and navigate browser to http://localhost:8887.
2. To run prod version, use npm run build && npm run prod and then navigate browser to http://localhost:8888

NOTE Debug version of pptr.dev doesn't require any build steps; serving index.html with any static server is sufficient.

NOTE Debug version of pptr.dev doesn't include service worker to simplify development

Dependencies

• commonmark.js is used to parse and render markdown documentation
• idb-keyval is used to work with IndexedDB
• codemirror is used to highlight code snippets inside markdown

FAQ

Q: Does pptr.dev use Custom Elements?

No. pptr.dev creates HTML elements with descriptive names to make markup nicer; this approach works in old browsers as well.
