Build a Plugin or Middleware

import { middleware, Redop } from "@redopjs/redop";

const requestIdPrefix = middleware(async ({ ctx, next }) => {
  (ctx as Record<string, unknown>).shortRequestId = ctx.requestId.slice(0, 8);
  return next();
});

new Redop({ serverInfo: { name: "middleware-demo" } })
  .middleware(requestIdPrefix)
  .tool("hello", {
    handler: ({ ctx }) => ({
      requestId: ctx.requestId,
      shortRequestId: (ctx as Record<string, unknown>).shortRequestId,
    }),
  });
