# `draft-js-prism-plugin`

A DraftJS plugin to add syntax highlighting support to your code blocks. Use in combination with [`draft-js-plugins`](https://github.com/draft-js-plugins/draft-js-plugins).

## Usage

First, create the plugin and add it to the `plugins` array of your PluginsEditor:

```JS

import Prism from 'prismjs';

import createPrismPlugin from 'draft-js-prism-plugin';

import "prismjs/themes/prism.css"; // add prism.css to add highlights  

class MyEditor extends React.Component {

  constructor(props) {

    super(props);

    const prismPlugin = createPrismPlugin({

      // It's required to provide your own instance of Prism

      prism: Prism

    });

    this.state = {

      plugins: [prismPlugin]

    }

  }

  render() {

    return (

      

    )

  }

}

```

Now add a `language` key to the data of the code block you want to highlight:

```JS

// TODO: Somehow get a code block and its key, this is up to you

const { block, key } = getCurrentBlock();

if (block.getType() !== "code-block") return;

// Replace the code block with a new one with the data.language changed to "javascript"

const data = block.getData().merge({ language: 'javascript' });

const newBlock = block.merge({ data });

const newContentState = currentContent.merge({

  blockMap: blockMap.set(key, newBlock),

  selectionAfter: currentSelection

})

// Now that code block will be highlighted as JavaScript!

this.setState({

  editorState: EditorState.push(editorState, newContentState, "change-block-data")

})

```
