Code Kitchen 🧑‍🍳

Code Kitchen is a React live-coding playground which allows the developers to embed React component demos into a React UI library’s web documents.

Compared to other solutions, it supports the following features:

• Private source code dependencies support 🔒
• Multiple files in a single demo
• CSS (CSS modules) and JSON files
• A completely static solution without the need for a remote server 🔌
• Type hints in the code editor

Demo 🎩

Check out the demo at https://freewheel.github.io/code-kitchen/home

Usage

Install with npm install code-kitchen.

Note: due to the size of esbuild-wasm and monaco-editor, they are not bundled with this library. By default they are loaded via jsDelivr CDN. You can configure this by calling setup in the runtime.

You can checkout a minimum example at this Code Sandbox.

Minimal setup

import * as React from "react";
import { Playground, setup } from "code-kitchen";

import * as privateLib from "my-private-lib";

const dependencies = {
  react: React,
  "my-private-lib": privateLib,
};

const customRequire = (key: string) => {
  const res = (dependencies as any)[key];

  if (res) {
    return res;
  }

  throw new Error("DEP: " + key + " not found");
};

// Two files for the demo playground
const files = [
  {
    code: `
import { Button } from "my-private-lib";
import "./styles.css";

export default function Demo() {
  return <Button>Button</Button>;
}
  `,
    filename: "App.jsx",
  },
  {
    code: `button { width: 200px; }`,
    filename: "styles.css",
  },
];

export default () => {
  return <Playground initialFiles={files} require={customRequire} />;
};

With MDX

Most of the time you may want to use Code Kitchen in a MDX document. You can checkout docs/components/MDXPlayground.mdx as a real-life example.

Add Intelligent type suggestion

You can access Monaco instance by import { useMonaco } from "code-kitchen". Checkout docs/components/use-init-monaco.ts as a real-life example.

Local Development

This library is developed with a typical Next.js document site.

Prerequisites

• Node.js
• pnpm

Install and start

# Under the root of the repository
