The commit contains the following structural elements, to communicate intent to the
consumers of your library:
1.**fix:** a commit of the _type_`fix` patches a bug in your codebase (this correlates with [`PATCH`](http://semver.org/#summary) in semantic versioning).
1.**feat:** a commit of the _type_`feat` introduces a new feature to the codebase (this correlates with [`MINOR`](http://semver.org/#summary) in semantic versioning).
1.**BREAKING CHANGE:** a commit that has a footer `BREAKING CHANGE:`, or appends a `!` after the type/scope, introduces a breaking API change (correlating with [`MAJOR`](http://semver.org/#summary) in semantic versioning).
1._types_ other than `fix:` and `feat:` are allowed, for example [@commitlint/config-conventional](https://github.com/conventional-changelog/commitlint/tree/master/%40commitlint/config-conventional) (based on the [the Angular convention](https://github.com/angular/angular/blob/22b96b9/CONTRIBUTING.md#-commit-message-guidelines)) recommends `build:`, `chore:`,
`ci:', `docs:`, `style:`, `refactor:`, `perf:`, `test:`, and others.
1._footers_ other than `BREAKING CHANGE: <description>` may be provided and follow a convention similar to
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 parentheses, e.g., `feat(parser): add ability to parse arrays`.
The key words “MUST”, “MUST NOT”, “REQUIRED”, “SHALL”, “SHALL NOT”, “SHOULD”, “SHOULD NOT”, “RECOMMENDED”, “MAY”, and “OPTIONAL” in this document are to be interpreted as described in [RFC 2119](https://www.ietf.org/rfc/rfc2119.txt).
1. A longer commit body MAY be provided after the short description, providing additional contextual information about the code changes. The body MUST begin one blank line after the description.
1. The units of information that make up conventional commits MUST NOT be treated as case sensitive by implementors, with the exception of BREAKING CHANGE which MUST be uppercase.
We recommend that you proceed as if you've already released the product. Typically *somebody*, even if it's your fellow software developers, is using your software. They'll want to know what's fixed, what breaks etc.
Go back and make multiple commits whenever possible. Part of the benefit of Conventional Commits is its ability to drive us to make more organized commits and PRs.
### Doesn’t this discourage rapid development and fast iteration?
It discourages moving fast in a disorganized way. It helps you be able to move fast long term across multiple projects with varied contributors.
### Might Conventional Commits lead developers to limit the type of commits they make because they'll be thinking in the types provided?
Conventional Commits encourages us to make more of certain types of commits such as fixes. Other than that, the flexibility of Conventional Commits allows your team to come up with their own types and change those types over time.
### How does this relate to SemVer?
`fix` type commits should be translated to `PATCH` releases. `feat` type commits should be translated to `MINOR` releases. Commits with `BREAKING CHANGE` in the commits, regardless of type, should be translated to `MAJOR` releases.
### How should I version my extensions to the Conventional Commits Specification, e.g. `@jameswomack/conventional-commit-spec`?
We recommend using SemVer to release your own extensions to this specification (and
encourage you to make these extensions!)
### What do I do if I accidentally use the wrong commit type?
#### When you used a type that's of the spec but not the correct type, e.g. `fix` instead of `feat`
Prior to merging or releasing the mistake, we recommend using `git rebase -i` to edit the commit history. After release, the cleanup will be different according to what tools and processes you use.
#### When you used a type *not* of the spec, e.g. `feet` instead of `feat`
In a worst case scenario, it's not the end of the world if a commit lands that does not meet the conventional commit specification. It simply means that commit will be missed by tools that are based on the spec.
### Do all my contributors need to use the conventional commit specification?
No! If you use a squash based workflow on Git lead maintainers can clean up the commit messages as they're merged—adding no workload to casual committers.
A common workflow for this is to have your git system automatically squash commits from a pull request and present a form for the lead maintainer to enter the proper git commit message for the merge.
The Conventional Commit specification is inspired by, and based heavily on, the [Angular Commit Guidelines](https://github.com/angular/angular/blob/22b96b9/CONTRIBUTING.md#-commit-message-guidelines).
