Developing Spree

Overview

This guide covers all the necessary steps to contributing to Spree source code. We’re happy you’re here!

Fork Spree repo

Go to Spree GitHub repository and click Fork button. This will create a copy of Spree repository on your GitHub account. See Github Documentation for more information on forking.

Setup locally

  1. Clone the your fork repository

    git clone git://github.com/your_github_username/spree.git
cd spree

  2. Install the gem dependencies

    bundle install

Fix Bundle errors on MacOS

If bundle install fails that means you’re missing some required system libraries.

Firstly, ensure you hve homebrew installed. You will need to install some packages needed to run Spree and Rails applications in general:

brew install openssl mysql postgresql sqlite imagemagick

Create Sandbox application

Spree is meant to be run within the context of Rails application and the source code is essentially a collection of gems. You can easily create a sandbox application inside of your cloned source directory for testing purposes.

This will setup a Rails application with Spree and some essential extensions and gems pre-installed with some data seeded Sandbox application is not meant to be run on production!

bundle exec rake sandbox

For headless sandbox please run:

SPREE_HEADLESS=true bundle exec rake sandbox

By default Sandbox uses SQLite database. But you can switch to PostgreSQL:

DB=postgres bundle exec rake sandbox

or MySQL:

DB=mysql bundle exec rake sandbox

You can also combine those options:

SPREE_HEADLESS=true DB=postgres bundle exec rake sandbox

Start the server

cd sandbox
bundle exec rails s

Performance in development mode

You may notice that your Spree store runs slower in development environment. This can be because in development each asset (css and javascript) is loaded separately. You can disable it by adding the following line to config/environments/development.rb.

config.assets.debug = false

Caching

Also in development caching is disabled by default. To turn on caching run:

bundle exec rails dev:cache

You will need to restart rails server after this change.

Making changes

Create a new branch for your changes. Do not push changes to the main branch. Branch name should be human readable and informative, eg.

  • bug fixes: fix/order-recalculation-total-bug
  • features: feature/my-new-amazing-feature

Running Tests

We use CircleCI to run the tests for Spree.

You can see the build statuses at https://circleci.com/gh/spree/spree.

Each gem contains its own series of tests, and for each directory, you need to do a quick one-time creation of a test application and then you can use it to run the tests. For example, to run the tests for the core project.

cd core
bundle exec rake test_app
bundle exec rspec spec

If you would like to run specs against a particular database you may specify the dummy app’s database, which defaults to sqlite3.

DB=postgres bundle exec rake test_app

If you want to run specs for only a single spec file

cd core
bundle exec rspec spec/models/spree/state_spec.rb

If you want to run a particular line of spec

cd core
bundle exec rspec spec/models/spree/state_spec.rb:7

Running integration tests on MacOS

We use chromedriver to run integration tests. To install it please use this command:

brew cask install chromedriver

Submitting Changes

Please keep your commit history meaningful and clear. This guide covers it quite well and we recommend reading it, not only for Spree project but for any IT project overall.

  1. Push your changes to a topic branch in your fork of the repository.

    git push -u origin fix/order-recalculation-total-bug

  2. Create a Pull request - please follow this guide

    If your changes references Github issues, please mark which issue you’re fixing by adding Fixes #<number or url of the issue> in the commit name or PR title/description. This will automatically mark that issue as closed when your PR will be merged.

  3. Wait for CI to pass

  4. If CI passed wait for Spree Core team code review

    We’re aiming to review and leave feedback as soon as possible. We’ll leave you a meaningul feedback if needed.

That’s a wrap!

Thank you for participating in Open Source and improving Spree - you’re awesome!
