Passport-Shraga

passport-shraga is a passport.js authentication strategy that utilizes Shraga as an saml-idp proxy.

Usage

passport.js

usage of passport-shraga is as followed:

const passport = require("passport");
const { Strategy } = require("passport-shraga");

passport.serializeUser((user, cb) => {
    //serialize function
});

passport.deserializeUser((id, cb) => {
    ///deserialize function
});

const config = {};

passport.use(new Strategy(config, (profile, done) => {
    console.log(`My Profile Is: ${profile}`);
    done(null, profile);
}))

Strategy configuration options (1):

callbackURL: callback url for Shraga to return the signed JWT. Can be absolute or relative ( http://my-domian/path-to-callback OR /path-to-callback )

bashragaURL: Full URL to the Shraga instance running.

transform: Function Or Mapping-Object that transforms profile returned from Shraga.

Strategy configuration options (2):

useEnrichId: (boolean) set to true if you want Shraga to return user profile with enrichId. set to false to return user profile with SAML provider id.

allowedProviders: Array of allowed identity provider names - if argument is provided only identity providers in this list are allowed to return user profiles. disallowed providers will be followed with authentication failure.

RelayState: If RelayState is provided its value will be returned with user profile inside jwtBody ( as 'RelayState' ).

Transform option:

the tranform option can be configured if early manipulation of the User profile is required. transform can ve a function or an object:

• in case of Function: the function will recieve the profile and do any manipulation wanted then returns a new profile object to replace current user Profile. example:

const tranform = (user) => {
  const fullName = `${user.firstName} ${user.lastNmae}`;
  return {...user, fullName};
}

• in case of Object: the object will act as a mapper and can decide which user properties will be passed on to Authenticate function and under which name they will be passed on as. example:

const transform = {"id": "userId", "firstName":"fname", "lastName":"lname"};

the returned object would be:

{userId: ObjectID, fname: String, lname: String}
