A repo for holding my dev.to posts, to allow me to keep them n source control and easily deploy them

dev.to's Issues

nestjs-passport-sessions blog no longer works

I was trying to follow along with your blog (and comments) but got stuck trying to initialize passport. I eventually decided to clone this repo and try your version to see what was different.

First, npm did not want to install due to conflicting dependencies

dev.to$ npm install
npm ERR! code ERESOLVE

Raw JSON explanation object:

So, I used npm install --force to get past that

When I tried to launch the app, I got a very similar error to the one which was blocking my own implementation
