LiveCodes — Configure Playground

LiveCodes uses configuration objects to define project content and behavior. Config can be passed to createPlayground or set via URL parameters.

Setup

import { createPlayground } from 'livecodes';

// Full config object
createPlayground('#container', {
  config: {
    title: 'My Project',
    markup: { language: 'html', content: '<h1>Hello</h1>' },
    style: { language: 'css', content: 'h1 { color: blue; }' },
    script: { language: 'javascript', content: 'console.log("hi")' },
    activeEditor: 'script',
  },
});

// Query params (simpler syntax)
createPlayground('#container', {
  params: {
    html: '<h1>Hello</h1>',
    css: 'h1 { color: blue; }',
    js: 'console.log("hi")',
    console: 'open',
  },
});

Core Patterns

Configure each editor

const config = {
  markup: {
    language: 'markdown',
    content: '# Title\n\nParagraph',
    contentUrl: 'https://example.com/content.md', // Alternative to content
  },
  style: {
    language: 'scss',
    content: '$color: blue; h1 { color: $color; }',
  },
  script: {
    language: 'typescript',
    content: 'const x: number = 1;',
    hiddenContent: 'export function helper() {}', // Hidden but evaluated
  },
};

Enable CSS processors

const config = {
  style: { language: 'css', content: '...' },
  processors: ['tailwindcss', 'autoprefixer'], // Processors run in order
};

Add external resources

const config = {
  stylesheets: ['https://cdn.jsdelivr.net/npm/tailwindcss@3/dist/tailwind.min.css'],
  scripts: ['https://cdn.jsdelivr.net/npm/lodash@4/lodash.min.js'],
};

Configure tests

const config = {
  tests: {
    language: 'typescript',
    content: `
      import { sum } from './script';
      test('sums numbers', () => {
        expect(sum(1, 2)).toBe(3);
      });
    `,
  },
};

Set display mode

const config = {
  mode: 'simple', // 'full' | 'focus' | 'simple' | 'lite' | 'editor' | 'codeblock' | 'result'
  view: 'result', // 'split' | 'editor' | 'result'
  readonly: true, // Read-only mode
};
