express-libcors

CORS middleware for Express

Usage no npm install needed!

<script type="module">
  import expressLibcors from 'https://cdn.skypack.dev/express-libcors';
</script>

This is an express middleware using libcors as the underlying algorithm for determining the CORS actions.

The express-libcors package provides a function libcors which wraps the libcors package and turns it into an express middleware:

const { libcors } = require( 'express-libcors' );

myExpressApp.use( libcors( /* options... */ ) );

The optional options object this libcors function takes, is directly forwarded to libcors, so check its documentation for valid values.
