nestjs-passport-sessions blog no longer works

[kdopen]

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 npm ERR! ERESOLVE unable to resolve dependency tree npm ERR! npm ERR! While resolving: dev.to@undefined npm ERR!

Raw JSON explanation object:

{ "code": "ERESOLVE", "current": { "name": "@nestjs/common", "version": "8.4.3", "whileInstalling": { "name": "dev.to", "path": "/home/.../dev.to" }, "location": "node_modules/@nestjs/common", "isWorkspace": false, "dependents": [ { "type": "dev", "name": "@nestjs/common", "spec": "^8.0.6", "from": { "location": "/home/.../dev.to" } } ] }, "currentEdge": { "type": "dev", "name": "@nestjs/common", "spec": "^8.0.6", "from": { "location": "/home/.../dev.to" } }, "edge": { "type": "peer", "name": "@nestjs/common", "spec": "^7.x", "error": "INVALID", "from": { "name": "@golevelup/nestjs-modules", "version": "0.4.4", "whileInstalling": { "name": "dev.to", "path": "/home/.../dev.to" }, "location": "node_modules/@golevelup/nestjs-modules", "isWorkspace": false, "dependents": [ { "type": "dev", "name": "@golevelup/nestjs-modules", "spec": "^0.4.2", "from": { "location": "/home/.../dev.to" } } ] } }, "strictPeerDeps": false, "force": false } 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
