React components

You can reuse TutorialKit’s React components in your own applications. They are designed to work well with the WebContainer API.

Here’s a simple editor that can be made with those components:

src

index.js

index.html

assets

logo.svg

package.json

Installation

These components use TutorialKit’s design system which is based on an atomic CSS engine, UnoCSS. You will need a few dependencies in order to use them:

npm

npm install @tutorialkit/react @tutorialkit/theme

pnpm

pnpm install @tutorialkit/react @tutorialkit/theme

Yarn

yarn add @tutorialkit/react @tutorialkit/theme

To setup UnoCSS with TutorialKit’s components, you need to create a uno.config.ts:

uno.config.ts

import { defineConfig } from '@tutorialkit/theme';

export default defineConfig({
  // add your UnoCSS config here: https://unocss.dev/guide/config-file
});

Then you need all the CSS variables used by TutorialKit design system:

src/theme.css

Next, you will need an integration. This depend on which build tool you have configured. See https://unocss.dev/integrations/ to configure yours.

Once this is done, make sure to import the CSS from your code so that it gets included:

src/main.ts

import 'uno.css';
import './theme.css';

See a full example on StackBlitz.

Components

These examples have references to the following files:

hooks/useTheme.ts

export function useTheme() {
  return 'light';
}

hooks/useWebcontainer.ts

import { WebContainer } from '@webcontainer/api';
import { useEffect } from 'react';

let webcontainerBooting = false;
let resolve!: (webcontainer: WebContainer) => void;

const webcontainerPromise = new Promise<WebContainer>((_resolve) => {
  resolve = _resolve;
});

export function useWebContainer() {
  useEffect(() => {
    if (!webcontainerBooting) {
      webcontainerBooting = true;

      WebContainer.boot({ workdirName: 'example' }).then((webcontainer) => {
        resolve(webcontainer);
      });
    }
  }, []);

  return webcontainerPromise;
}

FileTree

A component to list files in a tree view.

Example

src

index.js

index.html

assets

logo.svg

package.json

vite.config.js

import { useState } from 'react';
import FileTree from '@tutorialkit/react/core/FileTree';

export default function ExampleFileTree() {
  const [selectedFile, setSelectedFile] = useState(FILES[0]);

  return (
    <FileTree
      files={FILES}
      hideRoot
      className="my-file-tree"
      hiddenFiles={['package-lock.json']}
      selectedFile={selectedFile}
      onFileSelect={setSelectedFile}
    />
  );
}

const FILES = [
  '/src/index.js',
  '/src/index.html',
  '/src/assets/logo.svg',
  '/package-lock.json',
  '/package.json',
  '/vite.config.js',
];

Props

• files: string[] - The list of file paths to display. Each path should start with a / and be separated by / for directories. The array should be sorted in the order you want the files to be displayed while making sure that the files that share the same parent directory are grouped together.

• selectedFile?: string - The path of the file that should be selected. This will be highlighted in the tree.

• onFileSelect: (file: string) => void - A callback that will be called when a file is clicked. The path of the file that was clicked will be passed as an argument.

• hideRoot: boolean - Whether or not to hide the root directory in the tree. Defaults to false.

CodeMirrorEditor

A component to edit code with syntax highlighting using CodeMirror 6. This component supports multi-file edits by caching its state when moving between files.

Example

import type { EditorDocument, EditorUpdate, ScrollPosition } from '@tutorialkit/react/core';
import CodeMirrorEditor from '@tutorialkit/react/core/CodeMirrorEditor';
import { useState } from 'react';
import { useTheme } from './hooks/useTheme';

export default function ExampleCodeMirrorEditor() {
  const { editorDocument, theme, onChange, onScroll } = useEditorDocument();

  return (
    <CodeMirrorEditor
      theme={theme}
      doc={editorDocument}
      onChange={onChange}
      onScroll={onScroll}
      debounceChange={500}
      debounceScroll={500}
      className="h-full text-sm"
    />
  );
}

function useEditorDocument() {
  const theme = useTheme();
  const [editorDocument, setEditorDocument] = useState<EditorDocument>(DEFAULT_DOCUMENT);

  function onChange({ content }: EditorUpdate) {
    setEditorDocument((prev) => ({
      ...prev,
      value: content,
    }));
  }

  function onScroll(scroll: ScrollPosition) {
    setEditorDocument((prev) => ({
      ...prev,
      scroll,
    }));
  }

  return {
    theme,
    editorDocument,
    onChange,
    onScroll,
  };
}

const DEFAULT_DOCUMENT: EditorDocument = {
  filePath: 'index.js',
  loading: false,
  value: 'function hello() {\n  console.log("Hello, world!");\n}\n\nhello();',
};

Props

• doc?: EditorDocument - The document to edit.

• onChange?: (update: EditorUpdate) => void - A callback that will be called when the document is changed.

• onScroll?: OnScrollCallback - A callback that will be called when the editor is scrolled.

• id?: unknown - When this value changes, the editor clear its cache of known files.

• debounceChange?: number - The time in milliseconds to wait before calling the onChange callback after the document is changed.

• debounceScroll?: number - The time in milliseconds to wait before calling the onScroll callback after the editor is scrolled.

• autoFocusOnDocumentChange?: boolean - Whether or not to focus the editor when the document is changed. Defaults to false.

• theme: 'dark' | 'light' - The theme to use for the editor. Two values are available: light and dark.

• className?: string - A class name to apply to the root element of the component.

Terminal

A component to interact with a terminal using xterm.js. In the example below we lazy load and wrap the terminal in a Suspense boundary because xterm cannot be used in an SSR context. This is not required if you are not server-side rendering your application.

Example

import { Suspense, lazy, useEffect, useState } from 'react';
import { useTheme } from './hooks/useTheme';
import type { Terminal as XTerm } from '@xterm/xterm';
import { useWebContainer } from './hooks/useWebcontainer';

const Terminal = lazy(() => import('@tutorialkit/react/core/Terminal'));

export default function ExampleTerminal() {
  // only needed in astro because of SSR
  const [domLoaded, setDomLoaded] = useState(false);

  const theme = useTheme();
  const { setTerminal } = useTerminal();

  useEffect(() => {
    setDomLoaded(true);
  }, []);

  return (
    domLoaded && (
      <Suspense>
        <Terminal className="h-32" readonly={false} theme={theme} onTerminalReady={setTerminal} />
      </Suspense>
    )
  );
}

function useTerminal() {
  const webcontainerPromise = useWebContainer();
  const [terminal, setTerminal] = useState<XTerm | null>(null);

  useEffect(() => {
    if (!terminal) {
      return;
    }

    run(terminal);

    async function run(terminal: XTerm) {
      const webcontainer = await webcontainerPromise;
      const process = await webcontainer.spawn('jsh', {
        terminal: {
          cols: terminal.cols,
          rows: terminal.rows,
        },
      });

      process.output.pipeTo(
        new WritableStream({
          write(data) {
            terminal.write(data);
          },
        }),
      );

      const shellWriter = process.input.getWriter();

      terminal.onData((data) => {
        shellWriter.write(data);
      });
    }
  }, [terminal]);

  return {
    setTerminal,
  };
}

Props

• readonly?: boolean - Whether or not the terminal is readonly. Defaults to true.

• onTerminalReady?: (terminal: Terminal) => void - A callback that will be called when the terminal is ready. The Terminal instance from xterm will be provided as an argument.

• onTerminalResize?: (cols: number, rows: number) => void - A callback that will be called when the terminal is resized. The number of columns and rows will be provided as arguments. This is typically used to send a SIGWINCH signal to the running webcontainer process that is connected to the terminal.

• theme: 'dark' | 'light' - The theme to use for the editor. Two values are available: light and dark.

• className?: string - A class name to apply to the root element of the component.
