d8d-blockly

项目简介

这是一个基于React的区块编辑器项目，使用了d8d-blockly库来实现可视化的代码块编辑功能。项目包含两个主要组件：单一编辑器（App.tsx）和多编辑器（AppMulti.tsx）。

功能特点

单一编辑器 (App.tsx)

• 使用BlockEditor组件实现代码块编辑
• 支持自定义区块类型和分类
• 实时更新代码块、JavaScript代码和导入代码
• 支持复制和粘贴代码块

多编辑器 (AppMulti.tsx)

• 支持多个BlockEditor实例
• 可以动态添加新的编辑器
• 支持在不同编辑器之间切换
• 共享复制的代码块across编辑器

技术栈

• React
• TypeScript
• d8d-blockly库

使用说明

1. 克隆项目到本地
2. 安装依赖：npm install
3. 运行项目：npm start

代码示例

单一编辑器 (App.tsx)

import { useState } from "react";
import "./App.css";
import { BlockEditor, baseBlocks, baseCateItems } from "d8d-blockly";
import blockTypes from "@/app/blockTypes.json";
import { blocks, cates } from "@/app/test";

function App() {
  const [blockCode, setBlockCode] = useState<TBlockCodeMap>(new Map());
  const [copyBlocks, setCopyBlocks] = useState<TBlockNode[]>([]);
  const cateItems = [...baseCateItems, ...cates];
  const blocksCateConfig = {
    ...baseBlocks,
    ...blocks,
  };

  const onBlockChange = (
    blockCode: TBlockCodeMap,
    jsCode: string,
    importCode: string
  ) => {
    console.log(blockCode, [...blockCode.values()]);
    console.log(jsCode);
    console.log(importCode);
    setBlockCode(blockCode);
  };

  const onCopyBlocksChange = (blocks: TBlockNode[]) => {
    console.log("onCopyBlocksChange", blocks);
    setCopyBlocks(blocks);
  };

  return (
    <>
      <div className="db-w-screen db-h-screen">
        <BlockEditor
          blockCode={blockCode}
          onBlockChange={onBlockChange}
          blocksCateConfig={blocksCateConfig}
          cateItems={cateItems}
          blockTypes={blockTypes}
          copyBlocks={copyBlocks}
          onCopyBlocksChange={onCopyBlocksChange}

      </div>
    </>

多编辑器 (AppMulti.tsx)

  ]);

  // 添加新的 BlockEditor
  const addEditor = () => {
    setEditors([
