A koa middleware that checks if the origin matches the given base URL. If not a HTTP 403 is thrown.
koa-check-origin
requires Node.js >= v7.6.0
because Koa needs that as well.
$ npm install --save koa-check-origin
or if you use Yarn 🐈
$ yarn add koa-check-origin
const createCheckOriginMiddleware = require('koa-check-origin');
const app = new Koa();
const checkOriginMiddleware = createCheckOriginMiddleware('http://example.com');
app.use(checkOriginMiddleware);
