What is commitlint
commitlint checks if your commit messages meet the conventional commit format.
In general the pattern mostly looks like this:
type(scope?): subject #scope is optional; multiple scopes are supported (current delimiter options: "/", "\" and ",")
Real world examples can look like this:
chore: run tests on travis ci
fix(server): send cors headers
feat(blog): add comment section
Common types according to commitlint-config-conventional (based on the Angular convention) can be:
- build
- chore
- ci
- docs
- feat
- fix
- perf
- refactor
- revert
- style
- test
These can be modified by your own configuration.

Config
- Configuration is picked up from:

- Packages: cli, core
- See Rules for a complete list of possible rules
- An example configuration can be found at @commitlint/config-conventional
Shared configuration
A number of shared configurations are available to install and use with commitlint:
⚠️ If you want to publish your own shareable config then make sure it has a name aligning with the pattern commitlint-config-emoji-log or commitlint-config-your-config-name — then in extend all you have to write is emoji-log or your-config-name.
