React TinyMCE @Mention

Provides a simple yet flexible interface for adding @mention functionality into the TinyMCE rich text editor, built with React.js and Redux. Supports data sources that are simple Arrays as well as Promises, allows for data transformations, and exposes an interface for defining your own custom dropdown select menu.

Out of the box support for all major browsers and IE 9-11, and will work with IE8 assuming your app implements a polyfill before the plugin is loaded (see https://babeljs.io/docs/usage/polyfill for instructions).

Works best with react-tinymce, but will work in any environment where window.tinymce is available.

(NOTE: While this plugin is currently coupled with TinyMCE, extracting it from the current implementation should be fairly simple and we plan on releasing adaptors for other editors in the future.)

Installation

npm install --save react-tinymce-mention

Compatibility

The 0.2.x line uses React 13.x; if you're using React 15.x, pull 0.3.x.

Simple Use Case

import React from 'react';
import ReactDOM from 'react-dom';
import Mention from 'react-tinymce-mention';
import Editor from './components/Editor';

ReactDOM.render(
  <div>
    <Editor />
    <Mention dataSource={[
      'hello',
      'how',
      'are',
      'you'
    ]}
    />
  </div>
, document.getElementById('root')
);

In the simplest case, only dataSource is required; the list containing @mention matches is rendered with a default set of components that you can hijack via stylesheet classes. See src/mention/test-pages/simple.js for a working example.

Advanced (Complete API, minus `asyncDataSource`)

import React from 'react';
import ReactDOM from 'react-dom';
import Mention from 'react-tinymce-mention';
import Editor from './components/Editor';
import CustomList from './components/CustomList';
import CustomRTEMention from './components/CustomRTEMention';
import complexDataSource from './api/complexDataSource';

ReactDOM.render(
  <div>
    <Editor />
    <Mention
      delimiter={'@'}
      dataSource={complexDataSource}
      transformFn={dataSource => {
        return dataSource.map(result => {
          const { fullName } = result;

          // When transforming your dataSource, a `displayLabel` and
          // `searchKey` is required
          return {
            displayLabel: fullName,
            searchKey: fullName
          };
        });
      }}
      customListRenderer={({ clickFn, fetching, highlightIndex, matchedSources }) => {
        return (
          <CustomList
            fetching={fetching}
            highlightIndex={highlightIndex}
            matchedSources={matchedSources}
            onClick={clickFn}
          />
        );
      }}
      customRTEMention={({ delimiter, displayLabel, id, tinymceId }) => {
        return (
          <CustomRTEMention
            delimiter={delimiter}
            displayLabel={displayLabel}
            id={id}
            tinymceId={tinymceId}
          />
        );
      }}
      onAdd={({ changed, mentions }) => {
        console.log('Added', changed, mentions)
      }}
      onRemove={({ changed, mentions }) => {
        console.log('Removed', changed, mentions);
      }}
      showDebugger={true}
    />
  </div>
, document.getElementById('root')
);

In the advanced use-case you can define a

dataSource - Array or Promise
delimiter - Either '@' (default) or '#'.
transformFn - a function that processes your dataSource before it is injected into the plugin.
customListRenderer - A function that returns a component, allowing you to define your own dropdown list.
customRTEMention - A component that represents what is inserted into the TinyMCE input window. (Note: TinyMCE is aggressive about cleaning up markup as well as the format, so follow something similar to the example)
onAdd - A function that is called whenever you select a mention and it is inserted into the editor.
onRemove - Similar to the above, this function is called whenever a mention is removed.
showDebugger - Useful when developing a custom dropdown list, enabling this switch allows you to see all of the items available for selection as well as the mentions that have been currently selected.

See src/mention/test-pages/advanced.js for a working example.

Promise Example

import React from 'react';
import ReactDOM from 'react-dom';
import Mention from 'react-tinymce-mention';
import axios from 'axios';
import Editor from './components/Editor';

ReactDOM.render(
  <div>
    <Editor />
    <Mention
      showDebugger={true}
      delimiter={'#'}
      dataSource={axios.get('/public/api/complex.json')}
      transformFn={dataSource => {
        return dataSource.data.map(result => {
          const { fullName } = result;
          return {
            searchKey: fullName,
            displayLabel: fullName
          };
        });
      }}
    />
  </div>
, document.getElementById('root'));

In this example, if you pass in a Promise one of the hard requirements is that the array you return from your transformFn conforms to the above -- a searchKey and displayLabel is required. If you forget these properties an error will be thrown.

See src/mention/test-pages/promise.js for a working example.

Async Example

import React from 'react';
import ReactDOM from 'react-dom';
import Mention from 'react-tinymce-mention';
import axios from 'axios';
import Editor from './components/Editor';
import CustomList from './components/CustomList';

ReactDOM.render(
  <div>
    <Editor />
    <Mention
      showDebugger={true}
      delimiter={'@'}
      asyncDataSource={query => {
        return new Promise(resolve => {
          axios.get(`/public/api/complex.json?q=${query}`)
            .then(response => {
              resolve(transformDataSource(response.data));
            });
        });
      }}
      customListRenderer={({ clickFn, fetching, highlightIndex, matchedSources }) => {
        return (
          <CustomList
            fetching={fetching}
            highlightIndex={highlightIndex}
            matchedSources={matchedSources}
            onClick={clickFn}
          />
        );
      }}
    />
  </div>
, document.getElementById('root'));

function transformDataSource(dataSource) {
  return dataSource.map(result => {
    const { fullName } = result;
    return {
      searchKey: fullName,
      displayLabel: fullName
    };
  });
}

Lastly, if you would like to implement a Mention component that queries a an API when the user types, define an asynDataSource. As with the Promise example above, your final dataSource will need to conform to the searchKey and displayLabel requirement.

See src/mention/test-pages/async.js for a working example.

Troubleshooting

If you are not using react-tinymce and find that editor errors out stating that it can't find the Mention plugin to load, try initializing the plugin before your instance of TinyMCE.
