Koa Cross Origin Resource Sharing
A class for creating Koa middlewares that set CORS headers.
Installation
Install the package with NPM:
npm install @donutteam/koa-cors
Usage
To use this class, simply instantiate an instance and add it to your Koa stack:
import Koa from "koa";
import { CrossOriginResourceSharingMiddleware } from "@donutteam/koa-cors";
const app = new Koa();
const crossOriginResourceSharingMiddleware = new CrossOriginResourceSharingMiddleware();
// Be sure to add the execute function on the instance
// and NOT the instance itself
app.use(crossOriginResourceSharingMiddleware.execute);Options
allowCredentialsOrigins
This option is simply an array of origins that are allowed to include credentials.
const crossOriginResourceSharingMiddleware = new CrossOriginResourceSharingMiddleware(
{
allowCredentialsOrigins:
[
"https://donutteam.com",
],
});
