How do I return data from middleware?

[YakuBrangJa]

I want similar behavior for middleware like action and loader when I return data()

// this code straight up throwing error like
// Oops!: Unable to decode turbo-stream response
// (or)
// Error: An unexpected error occurred.

const handleErrorMiddlware: MiddlewareFunction = async ({request, context}, next) => {
  return data({}, {status: 200})
}

// this code works but bubble up to error boundary

const handleErrorMiddlware: MiddlewareFunction = async ({request, context}, next) => {
  throw data({}, {status: 200})
}

I don't want to blow up the UI with Error Boundary when the user click a button that fire Route's action().

There is no middleware in Remix v2

For all React Router related questions, please open discussion on https://github.com/remix-run/react-router/discussions

You don't return data from middleware, please review the React Router middleware documentation for more information and examples

Any alternative?

An alternative to what? The RR docs explains how to use middleware and pass data from middleware to other middleware or loader/action functions

I was referring to alternatives for accessing the hash in the clientLoader. Middleware could work, but since the fragment isn’t part of the request, I assume it wouldn’t be available there either — unless I’m missing something?
