RedwoodSDK
4th April 2025: This is a preview, whilst production-ready, it means some APIs might change

Quick Start

In this quick start you’ll go from zero to request/response in seconds and deploy to production in minutes!

Create a new project by running the following command, replacing <project-name> with your project name:

Terminal window
npx degit redwoodjs/sdk/starters/standard <project-name>

Start developing

Install the dependencies

cd <project-name>
pnpm install

Run the development server

RedwoodSDK is just a plugin for Vite, so you can use the same commands to run the development server as you would with any other Vite project.

pnpm dev
 
VITE v6.2.0  ready in 500 ms


➜  Local:   http://localhost:5173/
➜  Network: use --host to expose
➜  press h + enter to show help

Access the development server in your browser, by default it’s available at http://localhost:5173, where you should see “Hello World” displayed on the page.

Hello World

How exciting, your first request/response in RedwoodSDK!

Your first route

The entry point of your webapp is src/worker.tsx, open that file in your favorite editor.

Here you’ll see the defineApp function, this is the main function that “defines your webapp,” where the purpose is to handle requests by returning responses to the client.

src/worker.tsx
import { defineApp } from "@redwoodjs/sdk/worker";
import { route, render } from "@redwoodjs/sdk/router";


import { Document } from "@/app/Document";
import { Home } from "@/app/pages/Home";


export default defineApp([
  render(Document, [route("/", () => new Response("Hello, World!"))]),
]);

You’re going to add your own route, insert the "/ping" route handler:

src/worker.tsx
import { defineApp } from "@redwoodjs/sdk/worker";
import { route, render } from "@redwoodjs/sdk/router";


export default defineApp([
  render(Document, [
    route("/", () => new Response("Hello, World!")),
    route("/ping", function () {
      return <h1>Pong!</h1>;
    }),
  ]),
]);

Now when you navigate to http://localhost:5173/ping you should see “Pong!” displayed on the page.

Deploy to production

RedwoodSDK is built for the Cloudflare Development Platform. You can deploy your webapp to Cloudflare with a single command:

pnpm release
