+# registry-url [![Build Status](https://travis-ci.org/sindresorhus/registry-url.svg?branch=master)](https://travis-ci.org/sindresorhus/registry-url)
+
+> Get the set npm registry URL
+
+It's usually `https://registry.npmjs.org/`, but it's [configurable](https://docs.npmjs.com/misc/registry).
+
+Use this if you do anything with the npm registry as users will expect it to use their configured registry.
+
+
+## Install
+
+```
+$ npm install registry-url
+```
+
+
+## Usage
+
+```ini
+# .npmrc
+registry = 'https://custom-registry.com/'
+```
+
+```js
+const registryUrl = require('registry-url');
+
+console.log(registryUrl());
+//=> 'https://custom-registry.com/'
+```
+
+It can also retrieve the registry URL associated with an [npm scope](https://docs.npmjs.com/misc/scope).
+
+```ini
+# .npmrc
+@myco:registry = 'https://custom-registry.com/'
+```
+
+```js
+const registryUrl = require('registry-url');
+
+console.log(registryUrl('@myco'));
+//=> 'https://custom-registry.com/'
+```
+
+If the provided scope is not in the user's `.npmrc` file, then `registry-url` will check for the existence of `registry`, or if that's not set, fallback to the default npm registry.
