+
+## Overview
+
+The frontend is a Next.js app that allows users to upload a CSV file, which is then processed in the background using Trigger.dev tasks. The progress of the task is streamed back to the frontend in real-time using Trigger.dev Realtime.
+
+- A [Next.js](https://nextjs.org/) app with [Trigger.dev](https://trigger.dev/) for the background tasks.
+- [UploadThing](https://uploadthing.com/) to handle CSV file uploads
+- Trigger.dev [Realtime](https://trigger.dev/launchweek/0/realtime) to stream updates to the frontend.

+## Relevant code
+
+- View the Trigger.dev task code in the [src/trigger/csv.ts](https://github.com/triggerdotdev/examples/blob/main/realtime-csv-importer/src/trigger/csv.ts) file.
+- The parent task `csvValidator` downloads the CSV file, parses it, and then splits the rows into multiple batches. It then does a `batch.triggerAndWait` to distribute the work the `handleCSVRow` task.
+- The `handleCSVRow` task "simulates" checking the row for a valid email address and then updates the progress of the parent task using `metadata.parent`. See the [Trigger.dev docs](/runs/metadata#parent-and-root-updates) for more information on how to use the `metadata.parent` object.
+- The `useRealtimeCSVValidator` hook in the [src/hooks/useRealtimeCSVValidator.ts](https://github.com/triggerdotdev/examples/blob/main/realtime-csv-importer/src/hooks/useRealtimeCSVValidator.ts) file handles the call to `useRealtimeRun` to get the progress of the parent task.
+- The `CSVProcessor` component in the [src/components/CSVProcessor.tsx](https://github.com/triggerdotdev/examples/blob/main/realtime-csv-importer/src/components/CSVProcessor.tsx) file handles the file upload and displays the progress bar, and uses the `useRealtimeCSVValidator` hook to get the progress updates.
