## Install

```bash
# pnpm
pnpm add @conventional-changelog/git-client conventional-commits-filter conventional-commits-parser
# yarn
yarn add @conventional-changelog/git-client conventional-commits-filter conventional-commits-parser
# npm
npm i @conventional-changelog/git-client conventional-commits-filter conventional-commits-parser
```

Note: `conventional-commits-filter` and `conventional-commits-parser` are required only if you need `ConventionalGitClient#getCommits` method.

## Usage

```js
import {
  GitClient,
  ConventionalGitClient
} from '@conventional-changelog/git-client'

// Basic git client
const client = new GitClient(process.cwd())

await client.add('package.json')
await client.commit({ message: 'chore: release v1.0.0' })
await client.tag({ name: 'v1.0.0' })
await client.push('master')

// Conventional git client, which extends basic git client
const conventionalClient = new ConventionalGitClient(process.cwd())

console.log(await conventionalClient.getVersionFromTags()) // v1.0.0
```
