## <a name="commit"></a> Commit Message Guidelines
|
|
|
|
We have very precise rules over how our git commit messages can be formatted. This leads to **more
|
|
readable messages** that are easy to follow when looking through the **project history**. But also,
|
|
we use the git commit messages to **generate the Angular change log**.
|
|
|
|
### Commit Message Format
|
|
Each commit message consists of a **header**, a **body** and a **footer**. The header has a special
|
|
format that includes a **type**, a **scope** and a **subject**:
|
|
|
|
```
|
|
<type>(<scope>): <subject>
|
|
<BLANK LINE>
|
|
<body>
|
|
<BLANK LINE>
|
|
<footer>
|
|
```
|
|
|
|
The **header** is mandatory and the **scope** of the header is optional.
|
|
|
|
Any line of the commit message cannot be longer 100 characters! This allows the message to be easier
|
|
to read on GitHub as well as in various git tools.
|
|
|
|
The footer should contain a [closing reference to an issue](https://help.github.com/articles/closing-issues-via-commit-messages/) if any.
|
|
|
|
Samples: (even more [samples](https://github.com/angular/angular/commits/master))
|
|
|
|
```
|
|
docs(changelog): update changelog to beta.5
|
|
```
|
|
```
|
|
fix(release): need to depend on latest rxjs and zone.js
|
|
|
|
The version in our package.json gets copied to the one we publish, and users need the latest of these.
|
|
```
|
|
|
|
### Revert
|
|
If the commit reverts a previous commit, it should begin with `revert: `, followed by the header of the reverted commit. In the body it should say: `This reverts commit <hash>.`, where the hash is the SHA of the commit being reverted.
|
|
|
|
### Type
|
|
Must be one of the following:
|
|
|
|
* **build**: Changes that affect the build system or external dependencies (example scopes: gulp, broccoli, npm)
|
|
* **ci**: Changes to our CI configuration files and scripts (example scopes: Travis, Circle, BrowserStack, SauceLabs)
|
|
* **docs**: Documentation only changes
|
|
* **feat**: A new feature
|
|
* **fix**: A bug fix
|
|
* **perf**: A code change that improves performance
|
|
* **refactor**: A code change that neither fixes a bug nor adds a feature
|
|
* **style**: Changes that do not affect the meaning of the code (white-space, formatting, missing semi-colons, etc)
|
|
* **test**: Adding missing tests or correcting existing tests
|
|
|
|
### Scope
|
|
The scope should be the name of the npm package affected (as perceived by the person reading the changelog generated from commit messages.
|
|
|
|
The following is the list of supported scopes:
|
|
|
|
* **fe**
|
|
* **api**
|
