A concrete implementation of the specification described at [conventionalcommits.org](https://conventionalcommits.org/) for automated CHANGELOG generation and version management.

## Install

```bash
# yarn
yarn add -D conventional-changelog-conventionalcommits
# pnpm
pnpm add -D conventional-changelog-conventionalcommits
# npm
npm i -D conventional-changelog-conventionalcommits
```

## Indirect Usage (as preset)

Use the [Conventional Changelog CLI Usage](https://github.com/conventional-changelog/conventional-changelog/tree/master/packages/conventional-changelog#usage) with the `-p conventionalcommits` option.

## Direct Usage (as a base preset so you can customize it)

If you want to use this package directly and pass options, you can use the [Conventional Changelog CLI Usage](https://github.com/conventional-changelog/conventional-changelog/tree/master/packages/conventional-changelog#usage) and with the `--config` or `-n` parameter, pass a js config that looks like this:

```js
import createPreset from 'conventional-changelog-conventionalcommits'

createPreset({
  issuePrefixes: ['TEST-'],
  issueUrlFormat: 'https://myBugTracker.com/{{prefix}}{{id}}'
}).then((config) => {
  // do something with the config
})
```

or json config like that:

```json
{
  "options": {
    "preset": {
      "name": "conventionalcommits",
      "issuePrefixes": ["TEST-"],
      "issueUrlFormat": "https://myBugTracker.com/{{prefix}}{{id}}"
    }
  }
}
```

This last json config way passes the `preset` object to the `conventional-changelog-preset-loader` package, that in turn, passes this same `preset` object as the config for the `conventional-changelog-conventionalcommits`.

See [conventional-changelog-config-spec](https://github.com/conventional-changelog/conventional-changelog-config-spec) for available configuration options.

## Specific Options

| Option | Description |
|--------|-------------|
| ignoreCommits | Regular expression to match and exclude commits from the changelog. Commits matching this pattern will be ignored. |
| types | Array of commit type objects defining which types to include in the changelog. Hidden types are excluded from the changelog but may still trigger version bumps. Default value accessible via `DEFAULT_COMMIT_TYPES` export. |
| bumpStrict | When `true`, version bumps occur only for breaking changes or non-hidden commit types. When `false` (default), any commit can trigger a version bump. |
| scope | String or array of scope names to filter commits. Only commits with matching scopes will be included. When `scopeOnly` is `false` (default), commits without any scope are also included. |
| scopeOnly | When `true` and `scope` is specified, excludes commits that have no scope. When `false` (default), includes both scoped and unscooped commits when filtering by scope. |
