Main bundle on a new TanStack Start project takes ~20-30s to load

[FarazPatankar]

Hey y'all,

I used the CLI to generate a new Start project with Tailwind, Query and ShadCN. Then, I followed the Hosting guide to deploy it to Railway.

When I open my hosted application, the main bundle takes an incredibly large amount of time to load. The project is public and here's a link to the source code. I have made some changes on top of the generated application but I don't think they're the ones causing the issue as everything seems fine once the initial bundle has loaded.

Would appreciate any pointers on how to resolve this as I was looking forward to using Start for this project!

I was able to reproduce this on a barebones app generated with the CLI. The only change being target: "node-server" in vite.config.ts.

Edit: Minimal reproduction hosted here and the code can be found here.

cannot reproduce this when opening the page. might be a CDN routing issue?

Hey, I was speaking to Tanner about this on Twitter DMs so didn't exfil here but it might indeed be a CDN routing issue. Perhaps related to the cables being cut in the Red Sea causing outages in the Middle East.

I also moved my original service to the EU region on Railway and it has been fast since then!
