Welcome to the course! In this intro episode, we kick things off by showing a full demo of the Livewire CSV importer we're going to build together. The goal: handle huge CSV files (think millions of rows!) and import them into your Laravel app, all while keeping things responsive and avoiding any memory headaches.
You'll see that our importer isn't just for one kind of data—we import both products and customers, each living on their own model, and you can even run multiple imports at the same time. Uploading files is straightforward, and the UI lets you map CSV columns to your models' fields, choosing which are required.
A big feature is how progress is tracked: the import runs in the background using Laravel queues. You don’t have to keep your browser open—just upload your CSV, start the import, and even if you refresh or close the page, everything keeps going. Once it's done, you'll see the results.
We also touch on handling multiple large files at once, configuring queues, and even breaking up data into separate files if needed, all while keeping things flexible.
Plus, you'll get a glimpse of some magic under the hood: streaming the CSV files with generators to keep memory usage low—so even monster files won’t crash your server.
Next time, we'll roll up our sleeves and actually start building this importer from scratch. By the end of the course, you'll not only have a rock-solid CSV importer, but you'll also pick up lots of knowledge about Livewire, advanced queue tricks, generators, and more. Let's get started!
