PARTIAL data update

If you do router.invalidate(), then all the data from the loader will be reloaded, which is not very effective if there is a lot of data, but only part of it has been updated. through experimentation, I came to the conclusion that I need to do a hook to work with server functions in order to first receive data from loader, but then update only them. some server functions:...

server.ts context declaration merging conflict between react-router and react-start?

Hi - hopefully I understand correctly but I'm trying to pass in a custom context to my server.ts fetch handler.

Server dependency leaking to client?

I have a starter template that worked before: https://github.com/winstonpurnomo/turborepo-starter-v2, but now suddenly doesn't - when I try to load the index page, I get an error:

hook.js:608 Module "crypto" has been externalized for browser compatibility. Cannot access "crypto.getCiphers" in client code.

This stems from the @workos-inc/node package, which I only use in server functions. Does anyone have an explanation for if there is a proper way to protect a server-only dependency from seemingly leaking to client?...

SPA mode still server rendering even with prerendering disabled

Hey, I'm having a difficult time getting tanstack start to work in a completely SPA like way. I am migrating a previous tanstack router app to tanstack start but it just seems to have a hard time NOT using the server. I've read all the SPA guides and done every as suggested but it still keeps getting stuck on certain local storage or context usages. Any help is much appreciated!...

Proper way to compose 'request' middleware to get context type inference without duplication?

I noticed that by chaining request middleware in order to get context type inference middleware will be run more than once and am wondering if there's a proper strategy for composing them to get type inference but not duplication. I did see in the docs that for server function middleware that can be deduped by adding it to globals. Here's an example: addSessionToContext - makes session from request available in later context...

Any way to show loading page while waiting for beforeLoad

We would like to show some page loading spinners while waiting for some beforeLoad on nested routes. Seems that tanstack just renders empty/blank pages while waiting on all beforeLoads to complete? Any thoughts?
