vue3 封装一个通用echarts组件

实现这个组件需要引入echarts和vue-echarts插件，使用vue-echarts是因为它帮我们封装了一些很常用的功能，比如监听页面resize后重新渲染功能，本次组件只使用到了autoresize配置，其它可以根据官方文档按需选配

首先引入echarts和vue-echarts插件

npm install echarts vue-echarts -S

组件定义参数如下

import type { ECBasicOption } from 'echarts/types/dist/shared'const props = defineProps({// echarts options 传参option: {type: Object as PropType<ECBasicOption>,required: true,},// 容器宽度width: {type: String,default: '100%',},// 容器高度height: {type: String,default: '400px',},
})

组件代码如下

<script setup lang="ts">
import { PropType, provide } from 'vue'
import type { ECBasicOption } from 'echarts/types/dist/shared'
import { use } from 'echarts/core'
import { CanvasRenderer } from 'echarts/renderers'// 按需引入
import { PieChart, LineChart, FunnelChart, CustomChart } from 'echarts/charts'
import {TitleComponent,TooltipComponent,LegendComponent,GridComponent,ToolboxComponent,
} from 'echarts/components'import VChart, { THEME_KEY } from 'vue-echarts'
use([CanvasRenderer,PieChart,TitleComponent,TooltipComponent,LegendComponent,GridComponent,LineChart,ToolboxComponent,FunnelChart,CustomChart,
])// 传入主题
provide(THEME_KEY, 'light')const props = defineProps({option: {type: Object as PropType<ECBasicOption>,required: true,},width: {type: String,default: '100%',},height: {type: String,default: '400px',},
})
</script><template><div class="chart-container" :style="{ width, height }"><VChart class="w-full h-full" :option="props.option" autoresize /></div>
</template>
