小程序分包放置echarts组件

app.json

  "subPackages": [
    {
      "root":"commonPackage",
      "pages":[]
    }
  ],

pages同级目录加commonPackage

分包中放入echarts组件信息

使用

xx.json

上面是分包组件，下面是加载前替换组件

  "usingComponents": {
    "ec-canvas": "../../../commonPackage/components/echarts/ec-canvas"
  },
  "componentPlaceholder": {
    "ec-canvas": "view"
  },

xx.js

// 引入
let echarts
require('../../../commonPackage/components/echarts/echarts.js', utils => {
  echarts = utils
})
let chart = null;


// data:
    ec: {},


// func
// 初始化图表
  initChart(canvas, width, height, dpr) {
    chart = echarts.init(canvas, null, {
      width: width,
      height: height,
      devicePixelRatio: dpr // new
    });
    canvas.setChart(chart);
    chart.setOption(this.data.option);
    return chart;
  },


// 获取数据后渲染
    this.setData({
      ec: {
        onInit: this.initChart
      }
    })
