Comparing Text Editors in React: Draft.js vs Quill vs Slate React

#react #nextjs #webdev #texteditor

I never made my own text editor before, and the idea seemed tough. Even with some experience working on projects with editors, the thought of creating one from scratch was a bit overwhelming.

Recently, I had to deal with a text editor for a project. To figure things out, I did some research. In this article, I'm sharing what I learned and the code for different text editor libraries.

You can try out the Demo here.

Here are the things I looked for in text editors:

  • It should work well with React.
  • It must be free to use for commercial purposes.
  • It needs to function well on mobile web browsers.

As I was working on a mobile web application, having good compatibility with mobile browsers was crucial. Interestingly, it wasn't necessary for the libraries to offer specific React components, but they simply served as a React component.

It offers all the essential features you would expect from a text editor right from the start. What you need to do is to implement a toolbar.

However, there's a crucial issue. I should have read the documentation thoroughly before diving into the library.

On Github :

THIS PROJECT IS CURRENTLY IN MAINTENANCE MODE. It will not receive any feature updates, only critical security bug patches. On 31st December 2022 the repo will be fully archived.

Yes. This library is no longer active anymore. Even though it appeared working smoothly. There are some issues like toggle features and typing not working on mobile browsers.

The repository mentioned that the package lacks full support for mobile browsers, specifically iOS Safari and Chrome for Android.

Despite its ease of use and a high number of installations, I decided to exclude it from my list due to concerns about stability and mobile support.

Quill

import './styles.css';

interface QuillProps {
  onChange: (html: string) => void;
}

const modules = {
  toolbar: [
    [{ header: [1, 2, false] }],
    ['bold', 'italic', 'underline', 'strike', 'blockquote'],
    [{ list: 'ordered' }, { list: 'bullet' }],
  ],
};

const formats = [
  'header',
  'bold',
  'italic',
  'underline',
  'strike',
  'blockquote',
  'list',
  'bullet',
];

export default function Quill({ onChange }: QuillProps) {
  const [value, setValue] = useState('');

  useEffect(() => {
    onChange(value);
  }, [onChange, value]);

  return (
    <ReactQuill
      theme="snow"
      value={value}
      onChange={setValue}

I'm not certain if react-quill is an official library or not though, it's a widely-used React component library.

It comes with an embedded toolbar, and you have the option to choose from officially supported themes like Snow or Bubble. You can set up a powerful rich text editor in just a minute.

According to the repository, the library boasts remarkable compatibility and extensibility.

Before creating Slate, I tried a lot of the other rich text libraries out there—Draft.js, Prosemirror, Quill, etc. What I found was that while getting simple examples to work was easy enough, once you started trying to build something like Medium, Dropbox Paper or Google Docs, you ran into deeper issues... - In the slate github repository

This tool gives you everything you need to create your own text editor.

To be honest, understanding it may be a bit tricky at first. But, if you put in some effort to learn, making a cool and complex text editor becomes way easier than starting from scratch.

Before moving on, I first will share an error that I faced while trying out an example code.

Uncaught Error: Cannot get the start point in the node at path [] because it has no start text node.



<Slate editor={editor} initialValue={[]}>

// You need to make a starting point.

const initialValue: any = [
  {
    type: 'paragraph',
    children: [
      {
        text: '',
      },
    ],
  },
];

<Slate editor={editor} initialValue={initialValue}>
Enter fullscreen mode Exit fullscreen mode

I thought using an empty array for the initialValue property would be fine, but it caused an error. It took me a while to figure out that I needed to provide a starting point by passing the initialValue prop.

As this tool has a learning curve, I will break down some parts of the code for a better understanding.

Element and Leaf

There are two rendering types: Element and Leaf. Think of Element as a block style and Leaf as an inline style.

To display these, you have to create rendering components.



const Leaf = ({ attributes, children, leaf }: RenderLeafProps) => {
  if (leaf.bold) {
    children = <strong>{children}</strong>;
  }

  if (leaf.italic) {
    children = <em>{children}</em>;
  }

  if (leaf.underline) {
    children = <u>{children}</u>;
  }

  return <span {...attributes}>{children}</span>;
};

const Element = ({ attributes, children, element }: RenderElementProps) => {
  switch (element.type) {
    case 'blockquote':
      return <blockquote {...attributes}>{children}</blockquote>;
    case 'unordered-list-item':
      return <ul {...attributes}>{children}</ul>;
    case 'header-one':
      return <h1 {...attributes}>{children}</h1>;
    case 'header-two':
      return <h2 {...attributes}>{children}</h2>;
    case 'header-three':
      return <h3 {...attributes}>{children}</h3>;
    case 'list-item':
      return <li {...attributes}>{children}</li>;
    case 'ordered-list-item':
      return <ol {...attributes}>{children}</ol>;
    default:
      return <p {...attributes}>{children}</p>;
  }
};

// ...

const renderElement = useCallback(
    (props: RenderElementProps) => <Element {...props} />,
    []
  );
const renderLeaf = useCallback(
    (props: RenderLeafProps) => <Leaf {...props} />,
    []
  );

<Editable
    renderElement={renderElement}
    renderLeaf={renderLeaf}
/>

Check which styles are applied 



// Create Editor Object
const [editor] = useState(() => withReact(createEditor()));

// Types

const blockTypes = [
  'header-one',
  'header-two',
  'header-three',
  'blockquote',
  'unordered-list-item',
  'ordered-list-item',
  'paragraph',
  'list-item',
] as const;

const markTypes = ['bold', 'italic', 'underline'] as const;

const types = [...blockTypes, ...markTypes] as const;

type Type = (typeof types)[number];

// Is[*]Active

const isBlockActive = (type: Type) => {
  const { selection } = editor;
  if (!selection) return false;

  const [match] = Array.from(
    Editor.nodes(editor, {
      at: Editor.unhangRange(editor, selection),
      match: (n) =>
        !Editor.isEditor(n) &&
        SlateElement.isElement(n) &&
        (n as NodeProperty).type === type,
    })
  );

  return !!match;
};

const isMarkActive = (type: Type) => {
  const marks = Editor.marks(editor);
  return marks ? (marks as any)[type] === true : false;
};
Enter fullscreen mode Exit fullscreen mode

type is one of the styles you have defined such as paragraph, bold, and so on.

The functions isBlockActive and isMarkActive are what I just brought from an example on Github.

Since I didn't fully understand how each function and logic worked, I can't provide more details about the code. From my perspective, it appears that the documentation lacks explanations for certain parts.

To keep track of active toggles for a current node, I forcefully updated when the mousedown and keydown events were fired.



useEffect(() => {
    const editor =
      containerRef.current?.querySelector<HTMLDivElement>('[role=textbox]');
    if (!editor) return;

    const _forceUpdate = () => forceUpdate((v) => !v);

    const handleContentChange = () => {
      onChange(editor.innerHTML);
    };

    editor.addEventListener('keyup', handleContentChange);
    editor.addEventListener('mousedown', _forceUpdate);
    editor.addEventListener('keydown', _forceUpdate);

    return () => {
      editor.removeEventListener('keyup', handleContentChange);
      editor.removeEventListener('mousedown', _forceUpdate);
      editor.removeEventListener('keydown', _forceUpdate);
    };
    // eslint-disable-next-line react-hooks/exhaustive-deps
  }, []);
Enter fullscreen mode Exit fullscreen mode

However, I don't consider this a good approach for tracking them. In a real project, You may need to implement it differently.

Toggle

What I want to clarify about this code is how ol and ul are generated with li,. as it was confusing for me.

The process goes with the following steps:

  1. Unwrap Nodes.
  2. If the type is a list - ol or ul, set type to list-item which will turn into li.
  3. Wrap Nodes with the type - ol or li.

To trigger the onToggle event after toggling, I wrapped the call within a setTimeout function.

Export as HTML

Despite following the guidance in the document to use slate-plain-serializer for exporting contented as HTML, it didn't work as expected. Others faced the same issue. In the end, I resorted to retrieving the HTML code from the innerHTML attribute of the editor element.



const editor =
  containerRef.current?.querySelector<HTMLDivElement>('[role=textbox]');
if (!editor) return;

const handleContentChange = () => {
  onChange(editor.innerHTML);
};
Enter fullscreen mode Exit fullscreen mode

Wrap Up

Considering my brief experience with each library, there might be more efficient ways to use them.

My suggestion is that if you're aiming for a rich text editor with standard features and want to implement it effortlessly, then Quill could be the ideal choice. On the other hand, if you have the time to learn and plan to create a complex rich text editor like Medium, Google Docs, then slate might be a better option for you.

I hope you found it helpful.

Happy coding!
