An experimental attempt at using the fantastic T3 Stack entirely on the Edge runtime, with Next.js's beta App Router.
This is meant to be a place of hacking and learning. We're still learning how to structure apps using Next.js's new App Router, and comments are welcome in Discussions.
If you encounter an error (you will), please create an Issue so that we can fix bugs and learn together.
This is not intended for production. For a production-ready full-stack application, use the much more stable create-t3-app.
This project is not affiliated with create-t3-app.
This project represents the copy-pasting of work and ideas from a lot of really smart people. I think it's useful to see them all together in a working prototype.
- Edge runtime for all pages and routes.
- Type-safe SQL and schema management with drizzle-orm.
- While create-t3-app uses Prisma, Prisma can't run on the Edge runtime.
- Type-safe API with tRPC.
- App Router setup is copied from here.
- The installed tRPC version is currently locked to the experimental App Router tRPC client in
./src/trpc/@trpc, which formats the react-query query keys in a specific way that changed in later versions of tRPC. If you upgrade tRPC, hydration will stop working.
- Owned Authentication with Auth.js.
- create-t3-app uses NextAuth, which doesn't support the Edge runtime. This project uses NextAuth's successor, Auth.js, which does. Since Auth.js hasn't built support for Next.js yet, their SolidStart implementation is copied and slightly modified.
- Styling with Tailwind.
- It's just CSS, so it works just fine in the App Router.
- React components and layout from shadcn/ui
- They're also just CSS and Radix, so they work just fine in the App Router.
There are a few options that Server Components + tRPC + React Query afford us. The flexibility of these tools allows us to use different strategies for different cases on the same project.
- Fetch data on the server and render on the server or pass it to client components. Example.
- Fetch data on the server and use it to hydrate react-query's cache on the client. Example: Fetch and dehydrate data on server, then use cached data from server on client.
- Fetch data on the client.
- Fetch data the server but don't block first byte and stream Server Components to the client using a Suspense boundary. TODO: Example.

Run some commands.
pnpm i cp .env.example .env
-
Fill in .env.
-
Push your schema changes to a new PlanetScale database. Don't use this command on an existing database that you care about. It's destructive (and in beta).
pnpm db:push
