const opts = {
    issuer: 'https://sp.example.com',

};
const authnReq = new AuthnRequest(opts);
// generate base64 encoded SAMLRequest
var samlRequest1 = authnReq.toEncodedString();
// generate compressed base64 encoded SAMLRequest
var samlRequest2 = authnReq.toCompressedEncodedString();

SAMLResponse

To parse a SAMLResponse

const saml = require('samljs');
 
// the SAMLResponse body from HTTP Request body, such as express's req.body
const body = req.body.SAMLResponse;
 
saml.parseResponse(body, (err, resp) => {
    if (err) {
        // parse failed!
        console.log(err);
        return;
    }
 
    const attributes = resp.getAttributes();
