# koa-check-origin

A [koa](https://koajs.com) middleware that checks if the origin matches the given base URL. If not a [HTTP 403](https://http.cat/403) is thrown.

## Installation 🏗

`koa-check-origin` requires `Node.js >= v7.6.0` because Koa [needs that](https://github.com/koajs/koa#installation) as well.

```sh
$ npm install --save koa-check-origin
```

or if you use [Yarn](https://yarnpkg.com) 🐈

```sh
$ yarn add koa-check-origin
```

## Usage 🔨

```js
const createCheckOriginMiddleware = require('koa-check-origin');

const app = new Koa();

const checkOriginMiddleware = createCheckOriginMiddleware('http://example.com');
app.use(checkOriginMiddleware);
```
