Contributing

We value contributions to App Identity—bug reports, discussions, feature requests, and code contributions. New features should be proposed and discussed prior to implementation, and release of any new feature may be delayed until implemented in the reference implementations.

Before contributing patches, please read the Licence.

App Identity is governed under the Kinetic Commerce Open Source Code of Conduct.

Code Guidelines

We have several guidelines to contributing code through pull requests to App Identity reference implementations:

  • All code changes require tests. In most cases, this will be added or updated unit tests for the implementations: ExUnit (Elixir), minitest (Ruby), or vitest (Typescript).

    In some cases, new integration tests will be required, which will require updates to the integration test generators for all implementations.

  • We use code formatters, static analysis tools, and linting to ensure consistent styles and formatting. There should be no warnings output from compile or test run processes.

  • Proposed changes should be on a thoughtfully-named topic branch and organized into logical commit chunks as appropriate.

  • Use Conventional Commits with our conventions.

  • Versions must not be updated in pull requests; implementations may have other restrictions on file updates as they are part of the release process.

  • Documentation should be added or updated as appropriate for new or updated functionality.

  • New dependencies are discouraged and their addition must be discussed, regardless whether it is a development dependency, optional dependency, or runtime dependency.

  • All GitHub Actions checks marked as required must pass before a pull request may be accepted and merged.

Commit Conventions

App Identity has adopted the Conventional Commits format for commit messages. Because there are three reference implementations, integration tests, and a specification in this repository, the (scope) is required for most commits. The scope constraints the permitted commit types, as outlined below.

scope Purpose Allowed types Example
spec Updates to the App Identity spec. feat, fix, chore feat(spec)
int Updates to integration test specification or definitions feat, fix, chore feat(int)
int/elixir Updates to Elixir integration test support feat, fix, chore feat(int/elixir)
int/ruby Updates to Ruby integration test support feat, fix, chore feat(int/ruby)
int/ts Updates to Typescript integration test support feat, fix, chore feat(int/ts)
elixir Updates to the Elixir implementation feat, fix, chore, docs, deps docs(elixir)
ruby Updates to the Ruby implementation feat, fix, chore, docs, deps fix(ruby)
ts Updates to the Typescript implementation feat, fix, chore, docs, deps feat(ts)
Updates to global documentation or configuration feat, fix, chore, docs, deps chore

Updates to GitHub Actions may be global, but should be scoped if applied to a single implementation's workflow.

We encourage the use of Tim Pope's or Chris Beam's guidelines on the writing of commit messages

We require the use of git trailers for specific additional metadata and strongly encourage it for others. The conditionally required metadata trailers are:

  • Breaking-Change: if the change is a breaking change. Do not use the shorthand form (feat!(scope)) or BREAKING CHANGE.

  • Signed-off-by: required for non-Kinetic Commerce contributors, as outlined in the Licence.

  • Fixes or Resolves: If a change fixes one or more open issues, that issue must be included in the Fixes or Resolves trailer. Multiple issues should be listed comma separated in the same trailer: Fixes: #1, #5, #7, but may appear in separate trailers. While both Fixes and Resolves are synonyms, only one should be used in a given commit or pull request.

  • Related to: If a change does not fix an issue, those issue references should be included in this trailer.

  • Discussion: If a change is related to a discussion, those discussion URLs should be in Discussion trailers.
