Nitro and wasm

sad-indigo · 2025-12-10T22:41:20.096Z

Hey there, we are facing a lot of problems building our app. We have a big stack and are using some packages with wasm / or node-gyp addon. Is someone having the same issue with lib like zero-mq or tiny-secp256k1 ? The three shacking is having trouble finding the deps and file too keep and not

For example the errors after copying the .wasm file to the right place

We have been in touch on the github issue thanks @Manuel Schiller
Is there a way to run our app without nitro ?
We have a huge monorepo and it seems to include all of our deps even if they are not used in the app

S

still-lime•12/11/25, 8:11 PM

there are various ways

S

still-lime•12/11/25, 8:12 PM

simplest would be using srvx

S

still-lime•12/11/25, 8:12 PM

or you can use a custom server implementation

S

still-lime•12/11/25, 8:12 PM

or wrap start in an express server

S

sad-indigoOP•12/12/25, 5:00 PM

Thanks for the reply, by any chance do you have examples somewhere ?

S

still-lime•12/12/25, 7:11 PM

this project shows how to embed into express: https://github.com/TanStack/router/tree/main/e2e/react-start/custom-basepath

S

still-lime•12/12/25, 7:12 PM

this one here uses srvx cli: https://github.com/TanStack/router/blob/main/e2e/react-start/server-functions/package.json#L11
