This provides you a binary that you can use as a githook to validate the commit message. I recommend
[husky](http://npm.im/husky). You'll want to make this part of the `commit-msg` githook, e.g. when using [husky](http://npm.im/husky), add `"commitmsg": "validate-commit-msg"` to your [npm scripts](https://docs.npmjs.com/misc/scripts) in `package.json`.

Validates that your commit message follows this format:

```
<type>(<scope>): <subject>
```

Or without optional scope:

```
<type>: <subject>
```

## Installation

This module is distributed via [npm](https://www.npmjs.com/) which is bundled with [node](https://nodejs.org/) and
should be installed as one of your project's `devDependencies`:

```
npm install --save-dev validate-commit-msg
```

## Usage

### options

You can specify options in `.vcmrc`

```js
{
  "types": ["feat", "fix", "docs", "style", "refactor", "perf", "test", "chore", "revert"], // default
  "scope": {
    required: false, // default,
    allowed: ['button', 'card'], // default is '*' for anything,
    validate: false, // default,
    multiple: false // default
  },
  "warnOnFail": false, // default
  "maxSubjectLength": 100, // default
  "subjectPattern": ".+", // default
  "subjectPatternErrorMsg": "subject does not match subject pattern!", // default
  "helpMessage": "", // default
  "autoFix": false // default
}
```

or in `package.json`

```javascript
{
  "config": {
    "validate-commit-msg": {
      /* your config here */
    }
  }
}
```

`.vcmrc` has precedence, if it does not exist, then `package.json` will be used.

#### types

These are the types that are allowed for your commit message. If omitted, the value is what is shown above.

You can also specify: `"types": "*"` to indicate that you don't wish to validate types.

Or you can specify the name of a module that exports types according to the
[conventional-commit-types](https://github.com/adjohnson916/conventional-commit-types)
spec, e.g. `"types": "conventional-commit-types"`.

#### scope

This object defines scope requirements for the commit message. Possible properties are:

##### required

A boolean to define whether a scope is required for all commit messages.

##### allowed

An array of scopes that are allowed for your commit message.

You may also define it as `"*"` which is the default to allow any scope names.

##### validate

A boolean to define whether or not to validate the scope(s) provided.

##### multiple

A boolean to define whether or not to allow multiple scopes.

#### warnOnFail

If this is set to `true` errors will be logged to the console, however the commit will still pass.

#### maxSubjectLength

This will control the maximum length of the subject.

#### subjectPattern

Optional, accepts a RegExp to match the commit message subject against.

#### subjectPatternErrorMsg

If `subjectPattern` is provided, this message will be displayed if the commit message subject does not match the pattern.

#### helpMessage

If provided, the helpMessage string is displayed when a commit message is not valid. This allows projects to provide a better developer experience for new contributors.

The `helpMessage` also supports interpolating a single `%s` with the original commit message.

#### autoFix

If this is set to `true`, type will be auto fixed to all lowercase, subject first letter will be lowercased, and the commit will pass (assuming there's nothing else wrong with it).

### Node

Through node you can use as follows

```javascript
var validateMessage = require('validate-commit-msg');

var valid = validateMessage('chore(index): an example commit message');

// valid = true
```

### Other notes

If the commit message begins with `WIP` then none of the validation will happen.


## Credits

This was originally developed by contributors to [the angular.js project](https://github.com/angular/angular.js). I
pulled it out so I could re-use this same kind of thing in other projects.
