 A function to reject empty values with an http exception
+
+## Install
+
+```
+$ npm install --save http-reject-empty
+```
+
+## Usage
+```js
+const empty = require('http-reject-empty');
+
+const promise = User.find({}) // find a user in the db
+                  .then(empty);
+```
+If the promise returns a [falsy](https://developer.mozilla.org/en-US/docs/Glossary/Falsy) value, the promise is rejected with a 404 [http error](https://github.com/jshttp/http-errors)
