Welcome to the course! In this first episode, we jump right in with an overview and a quick demo of the Livewire CSV importer and exporter project that we'll be building together. The main goal here is to create a system that can easily handle massive amounts of records—think up to millions—without breaking a sweat or freezing your browser.
You'll see a sneak peek of the core features: a simple data table with thousands of records (in our case, transactions) and straightforward export and import tools. Exports and imports are queued so they run in the background; you don't have to awkwardly babysit the browser! We'll even set things up so you receive an email notification when a job is done.
We walk through exporting records, downloading the result, and getting an email alert. For importing, you just upload a file, kick it off, and let the job run—again, all handled in the background and updating existing records (not duplicating) thanks to upserting by a unique field.
Finally, we explain that everything is flexible: while the demo uses “transactions” as the main data table, the CSV import/export feature can be hooked up to any model in your app.
In this course, we'll start from scratch, build everything step-by-step, and by the end you'll have a production-ready tool to handle giant CSV files with ease. Let's get started!
