authjsgo

This is a package that aims to decode jwt produced using authjs only for auth.js or nextauth v5

example: config my auth.js

 const option = {
    // other configuratin
    session: { strategy: 'jwt', maxAge : 120  }, // 2 minute expired
    cookies: {
        sessionToken: {
            name: `mywebsite.session-token`, //session name token
                options: {
                httpOnly: false,
                    sameSite: 'none',
                    path: '/',
                    secure: true,
