How to contribute

Commit message formatting

This repo uses semantic-release for automating numerous processes such as bumping the version number appropriately, creating new tags/releases and updating the changelog. The entire process relies on the structure of commit messages to determine the version bump, which is then used for the rest of the automation.

Full details are available in the upstream docs regarding the Angular Commit Message Conventions. The key factor is that the first line of the commit message must follow this format:

type(scope): subject

• E.g. docs(contributing): add commit message formatting instructions.

Besides the version bump, the changelog and release notes are formatted accordingly. So based on the example above:

Documentation

• contributing: add commit message formatting instructions

• The type translates into a Documentation sub-heading.
• The (scope): will be shown in bold text without the brackets.
• The subject follows the scope as standard text.

This formula applies some customisations to the defaults, as outlined in the table below, based upon the type of the commit:

Type	Heading	Description	Bump (default)	Bump (custom)
build	Build System	Changes related to the build system	–
chore	–	Changes to the build process or auxiliary tools and libraries such as documentation generation	–
ci	Continuous Integration	Changes to the continuous integration configuration	–
docs	Documentation	Documentation only changes	–	0.0.1
feat	Features	A new feature	0.1.0
fix	Bug Fixes	A bug fix	0.0.1
perf	Performance Improvements	A code change that improves performance	0.0.1
refactor	Code Refactoring	A code change that neither fixes a bug nor adds a feature	–	0.0.1
revert	Reverts	A commit used to revert a previous commit	–	0.0.1
style	Styles	Changes that do not affect the meaning of the code (white-space, formatting, missing semi-colons, etc.)	–	0.0.1
test	Tests	Adding missing or correcting existing tests	–	0.0.1

• Adding BREAKING CHANGE to the footer of the extended description of the commit message will always trigger a major version change, no matter which type has been used.
