koa-check-origin

A koa middleware that checks if the origin matches the given base URL. If not a HTTP 403 is thrown.

Installation 🏗

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

Usage 🔨

const createCheckOriginMiddleware = require('koa-check-origin');
 
const app = new Koa();
 
const checkOriginMiddleware = createCheckOriginMiddleware('http://example.com');
app.use(checkOriginMiddleware);
