The Conventional Commits specification is a lightweight convention on top of commit messages. It provides an easy set of rules for creating an explicit commit history; which makes it easier to write automated tools on top of. This convention dovetails with SemVer, by describing the features, fixes, and breaking changes made in commit messages.
The commit message should be structured as follows:
<type>[optional scope]: <description>
[optional body]
[optional footer(s)]
The commit contains the following structural elements, to communicate intent to the consumers of your library:
- fix: a commit of the type
fix
patches a bug in your codebase (this correlates withPATCH
in Semantic Versioning). - feat: a commit of the type
feat
introduces a new feature to the codebase (this correlates withMINOR
in Semantic Versioning). - BREAKING CHANGE: a commit that has a footer
BREAKING CHANGE:
, or appends a!
after the type/scope, introduces a breaking API change (correlating withMAJOR
in Semantic Versioning). A BREAKING CHANGE can be part of commits of any type. 4.types other thanrefactor:
means that you changed src code but unlikefeat
no tests broke and no lines lost coverage. - types other than
fix:
andfeat:
are allowed, for example recommendsbuild:
,chore:
,ci:
,docs:
,style:
,perf:
,test:
, and others.
Additional types are not mandated by the Conventional Commits specification, and have no implicit effect in Semantic Versioning (unless they include a BREAKING CHANGE). A scope may be provided to a commit’s type, to provide additional contextual information and is contained within parenthesis, e.g., feat(parser): add ability to parse arrays
.
feat: allow provided config object to extend other configs
BREAKING CHANGE: `extends` key in config file is now used for extending other config files
feat!: send an email to the customer when a product is shipped
feat(api)!: send an email to the customer when a product is shipped
docs: correct spelling of CHANGELOG
- A scope can be provided after a type. A scope MUST consist of a noun describing a section of the codebase surrounded by parenthesis, e.g.,
fix(parser):
feat(lang): add Polish language
- Automatically generating CHANGELOGs.
- Automatically determining a semantic version bump (based on the types of commits landed).
- Communicating the nature of changes to teammates, the public, and other stakeholders.
- Triggering build and publish processes.
- Making it easier for people to contribute to your projects, by allowing them to explore a more structured commit history.
