Contributing

ViewComponent is intended to be a safe, welcoming space for collaboration. By participating you agree to abide by the Contributor Code of Conduct.

As of version 4, ViewComponent is considered feature-complete. While contributions are always welcome, we're unlikely to accept further breaking changes or significant feature additions.

Hi there! We're thrilled that you'd like to contribute to ViewComponent. Your help is essential for keeping it great.

If you have any substantial changes that you would like to make, please open an issue first to discuss them with us.

Maintainers tend to focus on areas of the project that are useful to them and their employers, but we're happy to pair with members of the community to enable work on other parts.

Contributions to this project are released to the public under the MIT license.

Slack community

While we prefer using Issues, Discussions, and PRs on GitHub, there is a ViewComponent Slack channel on the Ruby Central workspace: #oss-view-component. Reach out to joelhawksley@github.com for an invite.

Reporting bugs

When opening an issue to describe a bug, it's helpful to provide steps to reproduce it, either with failing tests in a pull request, or by sharing a repository that demonstrates the issue.

Creating a Rails application to demonstrate a ViewComponent bug

Run rails new --minimal view_component-bug-replica in the console.
Run bundle add view_component in the console. If testing against a previous version of ViewComponent, update the Gemfile to that version and run bundle install.
Run rails generate controller Home index.
Add root to: 'home#index'.
Add as little code as possible that's necessary to reproduce the issue. If possible, use the original code that caused the issue in the application.
Publish the repository and add a link to the bug report issue.

GitHub Codespaces

This repository includes configuration for GitHub Codespaces, making it easy to set up a cloud-based development environment. Follow GitHub's guide to get started.

The codespace environment includes a minimal Rails app with ViewComponent installed in the replicate-bug directory. To run the application:

Start the Rails server from the codespace's terminal with rails s.
Expose the port when prompted by the Visual Studio Code Web Editor.
Add the external URL to the config block in config/application.rb as prompted by the error.

Submitting a pull request

Fork and clone the repository.
Configure and install the dependencies: bundle exec appraisal install.
Make sure the tests pass: bundle exec appraisal rake (see below for specific cases).
Create a new branch: git checkout -b my-branch-name.
Add tests, make the change, and make sure the tests still pass.
Add an entry to the top of docs/CHANGELOG.md for the changes, no matter how small.
Push to the fork and submit a pull request.
Wait for the pull request to be reviewed and merged.

Running a subset of tests

Use m:

bundle exec m test/view_component/YOUR_COMPONENT_test.rb:line_number

Running tests for a specific version of Rails

Specify one of the supported versions listed in Appraisals:

bundle exec appraisal rails-8.0 rake

Documentation

Previewing changes locally

Navigate to /docs.
Configure and install the dependencies: bundle.
Run Jekyll: bundle exec jekyll serve.
Open the docs site at https://127.0.0.1:4000/.

Style guidelines

Keep it short.
Avoid unclear antecedents. Use the method name is too long instead of it's too long.
Avoid you, we, your, our.
Write in the active voice, avoiding the passive voice.
Refer to methods as #instance_method and .class_method.
Use the simplest examples possible.

Don't be afraid to ask for help! We recognize that English isn't the first language of many folks who contribute to ViewComponent.

To run the Vale prose linter locally, brew install vale and vale docs/.
