# [![NPM version][npm-image]][npm-url] [![Build Status][travis-image]][travis-url] [![Dependency Status][daviddm-image]][daviddm-url] [![Coverage Status][coveralls-image]][coveralls-url] > Generate a changelog from git metadata ## Usage You most likely only need to use this module if you're building a library that provides an abstraction on top of conventional commits, See [Getting started](https://github.com/conventional-changelog/conventional-changelog#getting-started) if you're an end-user. ```sh $ npm install --save conventional-changelog ``` ```js var conventionalChangelog = require('conventional-changelog'); conventionalChangelog({ preset: 'angular' }) .pipe(process.stdout); // or any writable stream ``` Or if you want to use your own custom preset: ```js var conventionalChangelog = require('conventional-changelog'); var config = require('@org/conventional-changelog-custom-preset'); conventionalChangelog({config}) .pipe(process.stdout); // or any writable stream ``` ## API ### conventionalChangelog([options, [context, [gitRawCommitsOpts, [parserOpts, [writerOpts]]]]]) Returns a readable stream. #### options See the [conventional-changelog-core](https://github.com/conventional-changelog/conventional-changelog/tree/master/packages/conventional-changelog-core) docs. The API is the same with the following changes or additions: ##### preset Type: `string` Possible values: `'angular', 'atom', 'codemirror', 'conventionalcommits', 'ember', 'eslint', 'express', 'jquery', 'jshint'` It's recommended to use a preset so you don't have to define everything yourself. Presets are names of built-in `config`. A scoped preset package such as `@scope/conventional-changelog-custom-preset` can be used by passing `@scope/custom-preset` to this option. **NOTE:** `options.config` will be overwritten by the values of preset. You should use either `preset` or `config`, but not both. ## [Notes for parent modules](https://github.com/conventional-changelog/conventional-changelog-core#notes-for-parent-modules) ## License MIT [npm-image]: https://badge.fury.io/js/conventional-changelog.svg [npm-url]: https://npmjs.org/package/conventional-changelog [travis-image]: https://travis-ci.org/conventional-changelog/conventional-changelog.svg?branch=master [travis-url]: https://travis-ci.org/conventional-changelog/conventional-changelog [daviddm-image]: https://david-dm.org/conventional-changelog/conventional-changelog.svg?theme=shields.io [daviddm-url]: https://david-dm.org/conventional-changelog/conventional-changelog [coveralls-image]: https://coveralls.io/repos/conventional-changelog/conventional-changelog/badge.svg [coveralls-url]: https://coveralls.io/r/conventional-changelog/conventional-changelog
