Learn yourself a simple login with Express, Formidable, Connect-Store using Redis and EJS template.
You have to install redis first. If you are on a linux system use your package manage to "install redis".
Once you have redis (which will come with redis-server, redis-cli, etc), then
npm install express-login
Then, run
node server.js
and open your web browser to http://localhost:4000
To make a clean skeleton for login/logout/registration for others to learn from.
That's all! Have a good day.
You can see an example of this in action and a whole lot more at one of my websites http://sweetcloudsvapor.com which includes recaptcha, and I integrate with Paypal/Stripe as well.
Making full apps in Express is simple fast, and really clean.
