The Ultimate Convex Beginner Tutorial - Part 3 - Scale

Learn how to prepare your Convex app for production with this hands-on walkthrough. In Part 3 of the Ultimate Convex Beginner Tutorial, you’ll go beyond building a chat app and start thinking about how to scale it. From adding efficient query indices to resolving write conflicts, this video helps developers understand how Convex handles performance at scale. You’ll learn how to: - Add a filterable query with `withIndex` - Define a schema using `schema.ts` - Create and apply a table index for fast querying - Handle concurrent writes with built-in Convex components like `scalableCounter` This video is ideal for full-stack developers, JavaScript/TypeScript devs, or anyone looking for a real-time backend that scales easily without managing infrastructure. Watch if you're serious about leveling up your Convex knowledge before deploying your next project.
