Rethrow Handler Plugin

The RethrowHandlerPlugin lets you catch and rethrow specific errors during request handling. Useful when your framework has its own error handling mechanism (e.g., global exception filters in NestJS, error middleware in Express).

Usage

import { ORPCError } from '@orpc/server'
import { RPCHandler } from '@orpc/server/fetch'
import {
  experimental_RethrowHandlerPlugin as RethrowHandlerPlugin,
} from '@orpc/server/plugins'

const handler = new RPCHandler(router, {
  plugins: [
    new RethrowHandlerPlugin({
      filter: (error) => {
        // Rethrow all non-ORPCError errors
        return !(error instanceof ORPCError)
      },
    }),
  ],
})

The handler can be any supported oRPC handler.
