An experimental, framework agnostic, small (~2.5kB) contenteditable state manager.

Motivation

Web editing is so hard even today. There are excellent libraries to make complex rich text editor, but they are too much for small purposes. Native textarea element is accessible and easy to use, but it's hardly customizable.

contenteditable attribute is a primitive for rich text editing, but as you may know it has so many problems. It has many edge case bugs, and has cross browser/OS/input device problems. And it doesn't work well with declarative frontend frameworks... However, at least the core of contenteditable is stable and it works in all browsers except the inconsistencies. This library aims to fill that gap, fix contenteditable to fit modern web development.

Demo

Install

npm install edix

Getting started

  1. Define your contents declaratively. There are rules you have to follow:

    • Direct children of the root are treated as rows. They must be elements, not text.
    • You must render <br/> in empty row (limitation of contenteditable).
    • (TODO)

  2. Call editable on mount, with HTMLElement which is the root of editable contents.

  3. Update your state with onChange, which will be called on edit.

  4. Call return value of editable on unmount for cleanup.

Here is an example for React.

import { useState, useEffect, useRef } from "react";
import { editable } from "edix";

export const App = () => {
  const ref = useRef<HTMLDivElement>(null);
  const [value, setValue] = useState("Hello world.");

  useEffect(() => {
    // 2. init
    const cleanup = editable(ref.current, {
      onChange: (v) => {
        // 3. update state
        setValue(v);
      },
    });
    return () => {
      // 4. cleanup
      cleanup();
    };
  }, []);

  // 1. render contents from state
  return (
    <div
      ref={ref}
      style={{
        backgroundColor: "white",
        border: "solid 1px darkgray",
        padding: 8,
      }}
    >
      {value.split("\n").map((t, i) => (
        <div key={i}>{t ? t : <br />}</div>
      ))}
    </div>
  );
};
