fastify-web-response

enables returning Response and ReadableStream as a result value in fastify routes.
so this code will be work:

import fastify from "fastify"
import fastifyWebResponse from "fastify-web-response"

const app = fastify();

app.register(fastifyWebResponse)

app.route({
  method: "GET",
  url: "/",
  handler() {
    return fetch("https://example-api.com");
  }
})

app.listen({
  port: 3000
})

you can also return ReadableStream

app.route({
  method: "GET",
  url: "/",
  async handler() {
    const response = await fetch("https://example-api.com");
    return response.body;
  }
})

Installation

npm i fastify-web-response
