Quick React.js example

npm i annotative-code -S

// 1. Because using web components in React is not mature yet
// we need to create a bridge React component <AnnotativeCode /> with `@lit/react`
import React from 'react';
import { createComponent } from '@lit/react';
import { AnnotativeCode as AnnotativeCodeWC } from 'annotative-code';

export const AnnotativeCode = createComponent({
  tagName: 'annotative-code',
  elementClass: AnnotativeCodeWC,
  react: React,
});

import { AnnotativeCode } from './AnnotativeCode';

// 2. Only import the language function and theme css in need can reduce the bundle size
import languageFn from 'annotative-code/bin/highlight.js/languages/javascript';
import themeCss from 'annotative-code/bin/highlight.js/css/a11y-dark';

// 3. Code/content to be highlighted
const content = `<Button variant="____variant____">
  Click me!
</Button>`;

// 4. Add annotations to the highlighted code!
const annotation = {
  variant: {
    type: 'string',
    knob: 'select',
    options: ['text', 'contained', 'outlined'],
    value: variant,
  },
};

<AnnotativeCode
  themeCss={themeCss}
  languageFn={languageFn}
  content={content}
  annotation={annotation}
  onValueChange={({ detail }) => setVariant(detail.valueObj.variant)}
/>;

Development

(WIP)

1. (One time only) Install dependencies

npm install

The annotative package is built with lit and the local development environment is using vite.

2. (One time only) Generate lit theme CSS and programming languages functions from highlight.js

node ./tools/generateThemes
node ./tools/generateProgLangs

3. Run the dev server

npm run dev
