What is web.dev?

This is the source code for web.dev, a learning website run by Google Chrome aimed at web developers. The site offers articles, guides, and tools covering topics like HTML, CSS, JavaScript, mobile web performance, and progressive web apps. The repository is now archived: the site has moved to a new platform, and this codebase is no longer accepting pull requests. While it was active, this repository contained everything needed to build the site locally: the frontend templates, the backend logic, and the written content itself. The site was built using a tool called Eleventy, which turns text files and templates into a finished website with roughly a thousand pages. For developers who wanted to contribute or run the site themselves, the README explains how to clone the project, install its dependencies using Node.js, and start a local preview server. Because the full site is large, it also describes a way to tell the build system to only process a subset of pages, which speeds things up considerably during development. Deployment was handled through Google Cloud Build, with the main branch automatically rebuilding and going live every hour on weekdays. Pull requests triggered a temporary staging URL via Netlify so reviewers could preview changes before they merged. If you come across this repository today, the main thing to know is that it is read-only and historical. The live web.dev site still exists, but it runs on a different platform now. This codebase is useful if you want to study how Google structured a large-scale documentation and learning site, or if you need to look up older content that may have existed in a previous version.
