Browser Adapter

Enable type-safe communication between browser scripts using the Message Port Adapter.

Between Extension Scripts

Browser extension Message Passing API doesn't support transferring binary data. Workaround: extend the RPC JSON Serializer to encode binary data as Base64.

Server (background/content script):

import { RPCHandler } from '@orpc/server/message-port'
import { onError } from '@orpc/server'

const handler = new RPCHandler(router, {
  interceptors: [onError(e => console.error(e))],
})
