LiveCodes SDK

The Software Development Kit (SDK) provides an easy, yet powerful, interface to embed and communicate with LiveCodes playgrounds.

The SDK is provided as a light-weight (less than 5kb gzipped), zero-dependencies npm package, that is also available from CDNs. It can be used to create playgrounds with a wide variety of configurations and embed options. In addition, SDK methods allow programmatic communication and control of the playgrounds during runtime.

Installation

npm i livecodes

Usage

Example: (open in LiveCodes)

import { createPlayground } from 'livecodes';

createPlayground('#container', {
  config: {
    markup: {
      language: 'markdown',
      content: '# Hello World!',
    },
  },
  view: 'result',
});

The JavaScript SDK is framework/library agnostic. However, wrapper components are also provided for popular libraries (currently React and Vue). The SDK can be used in Svelte directly without wrappers. TypeScript support provides type-safety and a great developer experience.

React SDK example: (open in LiveCodes)

import LiveCodes from 'livecodes/react';

const config = {
  markup: {
    language: 'markdown',
    content: '# Hello World!',
  },
};
const Playground = () => <LiveCodes config={config} view="result" />;
export default Playground;

Vue SDK example: (open in LiveCodes)

<script setup>
  import LiveCodes from 'livecodes/vue';

  const config = {
    markup: {
      language: 'markdown',
      content: '# Hello World!',
    },
  };
</script>

<template>
  <LiveCodes :config="config" view="result" />
</template>

In addition, the SDK allows creating links to playgrounds:

import { getPlaygroundUrl } from 'livecodes';

const url = getPlaygroundUrl({
  config: {
    markup: {
      language: 'markdown',
      content: '# Hello World!',
    },
  },
});

console.log(url);

See SDK docs for more details.
