Ruby API: Easily Find Ruby documentation
A fast, mobile-friendly documentation browser for Ruby and the Ruby standard library. Live at rubyapi.org.
Why?
The existing Ruby docs sites are hard to search and uncomfortable to read on a phone, which is where a lot of us actually look up docs. RubyAPI's job is to fix that: instant search, pages small enough to load over a slow connection, and layouts that work the same on a phone as on a laptop. It's free, supported by Ruby Central, and there are no ads.
The search experience is inspired by Dash. Documentation is imported directly from the official Ruby source via RDoc and indexed in OpenSearch.
We aim to improve the Ruby ecosystem by being:
- Readable on any size device
- Fast on any speed internet connection
- Relevant search results that surface useful APIs
- Search engine optimized pages for every API method
- Free, with no ads. Ever.
Getting started
The fastest way to try the project is GitHub Codespaces, which boots a fully configured environment in one click:
To run locally, you need Ruby 4 and Docker. PostgreSQL and OpenSearch run in containers. Then:
docker compose up -d # start PostgreSQL and OpenSearch
bin/setup # install gems, copy database.yml, prepare the database
bin/dev # start the Rails server on port 3000
bin/setup is also what you run when you pull updates: it refreshes gems and applies new migrations.
Alternatives to Docker
Docker is the only setup we officially support, but Podman tends to work fine if you already use it:
podman-compose up -d
Importing documentation
Pull docs for a single Ruby version:
bin/rails import:ruby[4.0]
Or every currently supported version at once:
bin/rails import:ruby:all
Running tests
bin/rails test
Tests hit a real database, so PostgreSQL and OpenSearch both need to be running.
Linting code
RuboCop is the linter. Run it to see violations, or pass -a to autocorrect what it can:
bin/rubocop
bin/rubocop -a
