@hc-master/renderer

智能设计渲染组件

基于pixiJS的渲染引擎，处理智能设计项目的渲染数据JSON Schema，以数据驱动的形式渲染图形图像的React渲染组件

Install

从npm获取 @hc-master/renderer

npm install @hc-master/renderer

Usage

在你的react项目中引入

import { Renderer } from '@hc-master/renderer'
// resDataJson为智能设计项目数据
function App() {
  const [index] = useState(0);
  const curData = useMemo(() => resDataJson.pagesData[index], [index]);
  const onMount = function(app) {
    console.log('==>>>::: 监听组件挂载');
  }
  const onCompleted = function(app) {
    console.log('==>>>::: 监听组件资源加载并渲染完成');
  }
  const onUnmount = function(app) {
    console.log('==>>>::: 监听组件卸载');
  }
  const handlePrev = function() {
    let v = indexRef.current-1;
    indexRef.current = v < 0 ? 0 : v
    setCurData(resDataJson.pagesData[indexRef.current])
  }
  const handleNext = function() {
    const count = resDataJson.pagesData.length-1;
    let v = indexRef.current+1;
    indexRef.current = v > count ? count : v;
    setCurData(resDataJson.pagesData[indexRef.current])
  }
  const handleChange = function() {
    const id = '9f6c1d44-d61c-4ad9-8f85-1d981f4548ce';
    const index = curData.stageJson.findIndex(item => item.id === id);
    // 找到指定数据
    const item = curData.stageJson[index] as FrameType;
    if (!item.photo) return
    // 改变数据内容
    item.photo = {
      ...item.photo,
