QUESTION
I'm currently learning how to authenticate users using Passportjs and a local strategy, I've been following the tutorial here: https://scotch.io/tutorials/easy-node-authentication-setup-and-local. I've made some changes to use sequelize instead of mongoose, and now when I log in I get redirected to a blank error page.
The console logs show:

i think you have used some depreciated functions that tutorial was done 2016 , 2 years ago , loads of things can change within 2 years ,
let's redo this following the below steps , assuming that you already finished the part of installing node.js .
make folder for your app :
mkdir AuthApp cd AuthApp
create the node app : npm init
You’ll be prompted to provide some information for Node’s package.json. Just hit enter until the end to leave the default configuration.
Next, we’ll need an HTML file to send to the client. Create a file called auth.html in the root folder of your app, not going to use so much html as we are going to do it for testing :
QUESTION
I'm trying to use passport so that users can log-on to my website using their google accounts. I'm using yarn with these relevant packages: passport@0.4.0, and passport-google-oauth20@^1.0.0. The general problem appears to be that the callback function specified in the GoogleStrategy
isn't being run so the server is trying to load a page that doesn't exist, causing several errors.
What's currently happening is that I start the server with nodemon, passing the Google client ID and secret to process variables who's values are used by the GoogleStrategy
(I have console logged them to make sure they are being correctly passed). I then visit the root page in the browser and click the log-in anchor which gets /auth/google
. The google log-in screen that displays possible accounts to log-in with appears. I select my account and the server then gets a GET request to /auth/google/callback?code=4/(a long string of characters)
which has a 500 error associated with it. After this, all the root page's files referenced in the pug file are GET requested, except that auth/google
is added to the front of every request except the stylesheet.
An example output:

Answered 2018-Jul-29 at 06:53I eventually tried adding session functionality to see if the combination of Passport and Google oauth 2.0 required it. That was the case, after adding basic session functionality, the callback function was called and the process completed. I didn't find documentation stating that sessions were required but after rereading the "read me" page in the GitHub repository, which is linked in my question above,
Also both sign-in button + callbackURL has to be share the same url, otherwise two cookies will be created and it will lead to lost your session
it is implied that sessions are required by Google oauth 2.0.
