+# package-json [![Build Status](https://travis-ci.org/sindresorhus/package-json.svg?branch=master)](https://travis-ci.org/sindresorhus/package-json)
+
+> Get metadata of a package from the npm registry
+
+
+## Install
+
+```
+$ npm install --save package-json
+```
+
+
+## Usage
+
+```js
+const packageJson = require('package-json');
+
+packageJson('ava').then(json => {
+	console.log(json);
+	//=> {name: 'ava', ...}
+});
+
+// Also works with scoped packages
+packageJson('@sindresorhus/df').then(json => {
+	console.log(json);
+	//=> {name: '@sindresorhus/df', ...}
+});
+```
+
+
+## API
+
+### packageJson(name, [options])
+
+#### name
+
+Type: `string`
+
+Name of the package.
+
+#### options
+
+Type: `Object`
+
+##### version
+
+Type: `string`<br>
+Default: `latest`
+
+Package version such as `1.0.0` or a [dist tag](https://docs.npmjs.com/cli/dist-tag) such as `latest`.
+
+The version can also be in any format supported by the [semver](https://github.com/npm/node-semver) module. For example:
+
+- `1` - get the latest `1.x.x`
+- `1.2` - get the latest `1.2.x`
+- `^1.2.3` - get the latest `1.x.x` but at least `1.2.3`
+- `~1.2.3` - get the latest `1.2.x` but at least `1.2.3`
+
+##### fullMetadata
+
+Type: `boolean`<br>
+Default: `false`
+
+By default, only an abbreviated metadata object is returned for performance reasons. [Read more.](https://github.com/npm/registry/blob/master/docs/responses/package-metadata.md)
+
+##### allVersions
+
+Type: `boolean`<br>
+Default: `false`
+
+Return the [main entry](https://registry.npmjs.org/ava) containing all versions.
+
+
+## Authentication
+
+Both public and private registries are supported, for both scoped and unscoped packages, as long as the registry uses either bearer tokens or basic authentication.
