passport-facebook | Facebook authentication strategy for Passport and Node.js | Authentication library

This is an old mean.js project. The project node version 4.4.4. I can run this project on my local machine using node 10.24.1.

When I deploy this project in heroku, many TypeErrors come in terminal while node-modules packages downloading. I followed some answers to solve this problem but unfortunately I can not succeed that is why I ask here.

My package-lock file is updated.

The Build Logs are as follows:

I have upgraded my angular to angular 13. when I run to build SSR it gives me following error.

This is my folder structure:

hello i new in backend and want to make a Authenticate facebook api with node js using express and i use passport but its not work and give me a page of html code as a response to sign in with facebook account this can handle when use web page the api may use with mobile application
my passport file that i use

I am trying to implement user authentication using Node.js, passport, and passport-google-oauth20. All register/login handling works fine except it cannot retrieve user email (All other data like 'displayName' or 'provider' are successfully saved into my DB but not 'email').

Could anyone help me to get user email using passport-google-oauth20?

My code:

I deployed a mern stack app to heroku and deployment was sucessful, the app works fine on local development server, but when I click on the deployed app link https://immense-sands-74220.herokuapp.com I get a Cannot Get / error, and after hours of searching i am pretty sure that there is a problem with my server code serving the client views when the app runs, I tried using the code below:

I tried using passportjs facebook on my website and tested on different browser but there’s a little bit problem when the link is from the facebook app itself specifically on IOS.

Package used: http://www.passportjs.org/packages/passport-facebook/

The scenario is:

• Share your login url to post in your facebook timeline
• Open facebook app on ipad
• Click the link that was posted on facebook timeline to open the login url and a popup browser from facebook app should appear.
• Click your facebook login using passportjs

Result: Session Expired popup appear and you’ll be sign out and ask to login again but not from your url but from the app itself so I’m not getting the response login from it since it is not from passportjs login anymore. Any idea how to solve this or why is this happening?

I have configured passport as below to use facebook authentication strategy using passport-facebook and it is working correctly. However, now i want to allow Twitter users to be able to authenticate as well using passport-twitter. How can i configure passport to use the two strategies?

I configured my project first with passport-google-oauth20 authentication and it was working fine. I added the passport-facebook after that and its working fine as well, however, after logging/registering with my FB account my redirecting URI which is supposed to be "http://localhost:3000/home" shows "http://localhost:3000/home#=" instead. It isn't showing any errors in the console and also working as it is intended to. I've got no clue what part of code I'm suppose to share with you guys as the functionality of the project is intact, so please let me know the snippet which may help you to better understand the issue.
