banger.show is a video app maker that heavily relies on background data processing. It's built with Inngest, which powers the video rendering pipeline for musicians, DJs, and labels. The app allows music industry people to create stunning visual assets for their music in just a few minutes without needing complex software. The video rendering pipeline includes updating render status, cropping audio files, rendering videos using remote workers, invalidating CDN cache, creating video thumbnails, and handling failures. Inngest simplifies the process by managing background jobs, orchestrating tasks, observing each step, and allowing for abstraction of lower-level processes.
