Transferring huge buffer

I'm using tRPC with superjson serializer in an Electron app. I have a router querry that loads an png image, parses it with

sharp

sharp

and sends it as a buffer to client to render inside canvas. For larger files (62MB) I'm getting a

Invalid array length

Invalid array length

error from superjson though. Can you think of a way to work around this issue?

Solution

I've implemented it by returning the url to fetch from my mutation and added

protocol.handle('local-raw', request =>
  net.fetch(`file:///${request.url.slice('local-raw://'.length)}`)
);

protocol.handle('local-raw', request =>
  net.fetch(`file:///${request.url.slice('local-raw://'.length)}`)
);

app.whenReady

app.whenReady

so the buffer doesn't have to go through tRPC
