This code is a bare minimum structure of Login using PassportJS. It demonstrates the implementation of passport-local, express-session with expressJS, NodeJS, EJS. It is without CSS. It is without the backend database, content management.

Where to go from here? Obviously, we could employ styling and data modelign, then on to JWT.

[x] PassportJS
[ ] JWT
[ ] Style CSS
[ ] Modeling using MongoDB Atlas

Then,

• Create the following files: .env .gitignore

• Insert into .gitignore

.env

node_modules

• Insert into .env

SESSION_SECRET=your_secret_could_be_anything_here

• Edit package.json

"scripts": { "devStart": "nodemon server.js" }

• To start the express server on the terminal:

npm run devStart

• Open browser to http://localhost:3000

Verify that the application is running after you cloned it. Hint, create .env file and enter the followings:

NODE_ENV=development
SESSION_SECRET=Anything you desirer here
PORT=3322

Replace 'hurricanemark' with your dockerhub's username

docker build -t hurricanemark/nodejs-passport-login:1.0 .

Then, run the application:

npm start

List docker image

Find the IMAGE ID of the newly build docker image

docker image ls

docker run -p 9999:8080 <IMAGE_ID>

Expected console output:

> node server.js

Listening on port 3322
