BIKE INDEX Cloud66 Deployment Status CircleCI Test Coverage View performance data on Skylight

Bike registration that works: online, powerful, free.

Registering a 🚲 only takes a few minutes and gives 🚴‍♀️ a permanent record linked to their identity that proves ownership in the case of a theft.

We're an open source project. Take a gander through our code, report bugs, or download it and run it locally.


We recommend asdf-vm for managing versions of Ruby and Node. Check the .tool-versions file to see the versions of the following dependencies that Bike Index uses.

Running Bike Index locally

This explanation assumes you're familiar with developing Ruby on Rails applications.

Toggle in development command default
Caching bundle exec rails dev:cache disabled
letter_opener bin/rake dev:letter_opener enabled
logging with lograge bin/rake dev:lograge enabled


See the internationalization docs for details.


We use RSpec and Guard for testing.

  • Run the test suite continuously in the background with bin/guard (watches for file changes/saves and runs those specs)

  • You may have to manually add the fuzzystrmatch extension, which we use for near serial searches, to your databases. The migration should take care of this but sometimes doesn't. Open the databases in postgres (psql bikeindex_development and psql bikeindex_test) and add the extension.

    CREATE EXTENSION fuzzystrmatch;

We use parallel_tests to run the test suite in parallel. By default, this will spawn one process per CPU in your computer.

  • Run all the tests in parallel with bin/rake parallel:spec

  • Run bin/rake parallel:prepare to synchronize the test db schema after migrations (rather than db:test:prepare).

  • Run specific files or test directories with bin/parallel_rspec <FILES_OR_FOLDERS>

  • Run Guard with parallelism bin/guard -G Guardfile_parallel

Code Hygiene

We use the following tools to automate code formatting and linting:

Run bin/lint to automatically lint the files and/or add auto formatters to your text editor (e.g. prettier-standard)


EditorConfig ensures whitespace consistency. See the Download a Plugin section of the EditorConfig docs to find a plugin appropriate to your editor.


StandardRB is an opinionated Ruby style guide, linter, and formatter - it is "a spiritual port of StandardJS".

See the how do I run standard in my editor section of the StandardRB docs to find an appropriate plugin for on-the-fly linting.


ESlint is configured to run on project JavaScript. To run it, issue yarn lint.

Keep track of development and community news.


Open a Pull request!

Don't wait until you have a finished feature before before opening the PR, unfinished pull requests are welcome! The earlier you open the pull request, the earlier it's possible to discuss the direction of the changes.

Once the PR is ready for review, request review from the relevant person.

If your pull request contains Ruby patches or features, you must include relevant Rspec tests.

... and go hard
