Is it necessary to use Start with a custom server when connecting to long-running processes?

Hopefully quick question since I've been reading through conversations... I use NATS (sort of like Kafka) for server-to-server communication. In my previous Fastify app, my NATS client could connect when the Fastify Server started and would stay connected while running the server. New messages would then be consumed from an async iterator as they arrived. I believe, to do something similar while using Start, I would need to build off of this example...

How to fetch data at build time for static deployment on Cloudflare Workers?

I’m using TanStack Start and deploying my site to Cloudflare Workers. I want to fetch some data at build time so it becomes static in the deployed site. From what I can tell, Static Server Functions won’t work in the Cloudflare Workers environment. Is there a recommended way to fetch data during the build step and have it baked into the static output when deploying?...

Jest and Playwright for Tanstack Start.

Hello. I was searching for testing resource for Jest/Playwright on Tanstack Start but I couldn't find any appropriate resource. Even the docs doesnt have any dedicated section on Testing Tanstack Start applications. Is there any update/possibility of introducing a dedicated testing documentation/resources for Tanstack Start? Thanks

Type inference gap between Tanstack Start and Tanstack Query

When a TanStack Start loader redirects based on query data (like redirecting if user is null), the runtime guarantees the route will never render in that state. But TypeScript doesn’t pick that up — it still infers user as User | null in the component. ```ts...

Dev server hot reload removes one API route

I have a very odd (and very minor) issue that I repeatedly run into. My workflow (using jj-vcs) involves me doing a lot of rebases or other changes to the git log. Very often I find that when I am running the vite dev server while performing these rebase operations, the automatic route tree generated by TanStack Start/Router (I believe - routeTree.gen.ts) will remove exactly one route from my route tree, until I restart the dev server, at which point it regenerates it back in and the file is once again unchanged. That route is consistently the one at const ApiElectricRouteImport = createFileRoute('/api/electric')()...

Migrate from Next.js Pages to Start or Router?

Our code base is a next JS application using the Pages router. We don’t do any SSR at all. All of our pages are static pages that use react query to fetch data from the client side. I’m curious if we were to try to move to tan stack router, should we use start or router only?...
