DevDocs aims to make reading and searching reference documentation fast, easy and enjoyable.
The app’s main goals are to: keep load times as short as possible; improve the quality, speed, and order of search results; maximize the use of caching and other performance optimizations; maintain a clean and readable user interface; be fully functional offline; support full keyboard navigation; reduce “context switch” by using a consistent typography and design across all documentations; reduce clutter by focusing on a specific category of content (API/reference) and indexing only the minimum useful to most developers.
DevDocs combines multiple developer documentations in a clean and organized web UI with instant search, offline support, mobile version, dark theme, keyboard shortcuts, and more.
DevDocs is made of two pieces: a Ruby scraper that generates the documentation and metadata, and a JavaScript app powered by a small Sinatra app.
The web app is all client-side JavaScript, written in CoffeeScript, and powered by a small Sinatra/Sprockets application. It relies on files generated by the scraper.
The scraper is responsible for generating the documentation and index files (metadata) used by the app. It’s written in Ruby under the Docs module.
