In this part of my Meteor tutorial series, I focus on the next obvious step after registration: letting users actually log in to the accounts they created. I walk through wiring up the login flow and then I do a couple of quality-of-life tweaks that make the codebase feel less “prototype-y” and more like something you can keep building on without hating yourself later. The main takeaway is that authentication isn’t just a button and a form—it’s how you structure your app so the UI and the account state play nicely together. I also point you to the full codebase and the step-by-step learning material so you can compare your implementation with mine and spot where you may have gone off-track. If you’re following the Meteor.js microblogging project, this is the episode that makes the app feel like a real product: users can come back, sign in, and continue where they left off.
