babel-transform-editor-jsx

⚠️ Experimental plugin ahead ⚠️

This repo contains a babeljs plugin that will transform Reactjs components into Editorjs Block tool.

Take for example the following React component:

import React from "react";

export const TITLE = "Image";
export const ICON =
  '<svg width="17" height="15" viewBox="0 0 336 276" xmlns="http://www.w3.org/2000/svg"><path d="M291 150V79c0-19-15-34-34-34H79c-19 0-34 15-34 34v42l67-44 81 72 56-29 42 30zm0 52l-43-30-56 30-81-67-66 39v23c0 19 15 34 34 34h178c17 0 31-13 34-29zM79 0h178c44 0 79 35 79 79v118c0 44-35 79-79 79H79c-44 0-79-35-79-79V79C0 35 35 0 79 0z"/></svg>';

const MyComponent = ({ editorContext, blockState, setBlockState }) => {
  // do what ever you want to do here with editorContext, blockState, setBlockState.
  return <div>My Tool</div>;
};

export default MyComponent;

The result after transpilation:

import { render, unmountComponentAtNode } from "react-dom";
import React from "react";

const MyComponent = (props) => {
  return /*#__PURE__*/ React.createElement("div", null, "My Tool");
};

export default class MyComponentBlock {
  root = null;
  blockState = null;
  editorContext = null;

  static get toolbox() {
    return {
      title: "Image",
      icon: '<svg width="17" height="15" viewBox="0 0 336 276" xmlns="http://www.w3.org/2000/svg"><path d="M291 150V79c0-19-15-34-34-34H79c-19 0-34 15-34 34v42l67-44 81 72 56-29 42 30zm0 52l-43-30-56 30-81-67-66 39v23c0 19 15 34 34 34h178c17 0 31-13 34-29zM79 0h178c44 0 79 35 79 79v118c0 44-35 79-79 79H79c-44 0-79-35-79-79V79C0 35 35 0 79 0z"/></svg>',
    };
  }

  constructor(editorContext) {
    this.editorContext = editorContext;
    this.root = document.createElement("div");
    this.setBlockState = this.setBlockState.bind(this);
  }

  setBlockState = (newState) => {
    this.blockState = newState;
  };
  render = () => {
    render(
      /*#__PURE__*/ React.createElement(MyComponent, {
        editorContext: this.editorContext,
        blockState: this.blockState,
        setBlockState: this.setBlockState,
      }),
      this.root
    );
    return this.root;
  };
  save = () => {
    return this.blockState;
  };
  destroy = () => {
    unmountComponentAtNode(this.root);
  };
}

Basically it wraps any React component with the Editorjs class definition and it will handle creating the host dom node, mount and unmounting the component if and only if its name ends with .block.js

Updating component state:

The plugin will create the following members on the class and will pass them as props to the component:

1. editorContext: is the API object that Editorjs passes to the tool constructor.
2. blockState: a property on the tool instance that holds the tool data that will be ultimately returned by the save method automatically.
3. setBlockState: a setter for blockState mentioned in point #2

Notes:

• TITLE and ICON must be exported as const in UPPERCASE in order for them to be captured by the plugin and used as toolbox configuration.
