# Build Optimization
|

|
## 构建优化
|
|
|
|
优化 UniApp + uCharts 项目的构建和性能。
|
|
|
|
### 代码分割
|
|
|
|
使用条件编译减少代码体积：
|
|
|
|
```vue
|
|
<template>
|
|
<view>
|
|
<!-- #ifdef H5 -->
|
|
<qiun-data-charts type="line" :opts="opts" :chartData="chartData" />
|
|
<!-- #endif -->
|
|
|
|
<!-- #ifdef MP-WEIXIN -->
|
|
<qiun-data-charts type="bar" :opts="opts" :chartData="chartData" />
|
|
<!-- #endif -->
|
|
</view>
|
|
</template>
|
|
```
|
|
|
|
### 组件按需引入
|
|
|
|
虽然 easycom 会自动引入，但可以优化：
|
|
|
|
```json
|
|
{
|
|
"easycom": {
|
|
"autoscan": true,
|
|
"custom": {
|
|
"qiun-data-charts": "@/uni_modules/qiun-data-charts/components/qiun-data-charts/qiun-data-charts.vue"
|
|
}
|
|
}
|
|
}
|
|
```
|
|
|
|
### 图表数据优化
|
|
|
|
```vue
|
|
<script>
|
|
export default {
|
|
data() {
|
|
return {
|
|
chartData: {},
|
|
opts: {
|
|
// 优化配置
|
|
enableScroll: false,
|
|
dataLabel: false,
|
|
legend: {
|
|
show: false
|
|
}
|
|
}
|
|
}
|
|
},
|
|
methods: {
|
|
// 数据采样，减少数据量
|
|
sampleData(data, maxPoints = 100) {
|
|
if (data.length <= maxPoints) {
|
|
return data
|
|
}
|
|
const step = Math.ceil(data.length / maxPoints)
|
|
return data.filter((_, index) => index % step === 0)
|
|
}
|
|
}
|
|
}
|
|
</script>
|
|
```
|
|
|
|
### 打包配置
|
|
|
|
在 manifest.json 中配置打包选项：
|
|
|
|
```json
|
|
{
|
|
"mp-weixin": {
|
|
"setting": {
|
|
"minified": true,
|
|
"postcss": true
|
|
}
|
|
},
|
|
"h5": {
|
|
"optimization": {
|
|
"treeShaking": {
|
|
"enable": true
|
|
}
|
|
}
|
|
}
|
|
}
|
|
```
|
|
|
|
### 注意事项
|
|
|
|
1. **条件编译**：使用条件编译减少代码体积
|
|
2. **数据优化**：合理控制数据量，避免过大
|
|
3. **配置优化**：合理配置图表选项，提高性能
|
|
4. **打包配置**：正确配置打包选项
|
|
5. **性能测试**：在不同平台测试性能
