'' : 'hidden' }`} 118 | style={styleObj} 119 | > 120 | 128 | 129 | 134 | 135 | 136 | 137 | ) 138 | } 139 | } 140 | 141 | ``` 142 | - 缓存服务 143 | 缓存服务对提高性能非常有帮助，比如canvas绘图需要图片是本地图片，可以通过数据字典的方式将图片的远程地址和下载到本地的地址进行一一对应，节省了大量的网络资源和时间 144 | ``` 145 | // services/cache.ts 缓存服务 146 | function Cache (name) { 147 | this.name = name 148 | } 149 | Cache.prototype = { 150 | set: function (key, value) { 151 | this[key] = value 152 | return this[key] 153 | }, 154 | get: function (key) { 155 | return this[key] 156 | }, 157 | clear: function () { 158 | // 清空 159 | Object.keys(this).forEach(v => { 160 | this[v] = null 161 | }) 162 | } 163 | } 164 | 165 | export const createCache = (name:string) => { 166 | return new Cache(name) 167 | } 168 | // 使用 169 | import {createCache} from '../../services/cache' 170 | class Page extends Component { 171 | cache = { 172 | source: createCache('source'), 173 | } 174 | // 下载照片并存储到本地 175 | downloadRemoteImage = async (remoteUrl = '') => { 176 | const cacheKey = `${remoteUrl}_localPath` 177 | const cache_source = this.cache['source'] 178 | let localImagePath = '' 179 | if (cache_source.get(cacheKey)) { 180 | // 有缓存 181 | return cache_source.get(cacheKey) 182 | } else { 183 | try { 184 | const result = await service.base.downloadFile(remoteUrl) 185 | localImagePath = result.tempFilePath 186 | } catch (err) { 187 | console.log('下载图片失败', err) 188 | } 189 | } 190 | return cache_source.set(cacheKey, localImagePath) 191 | } 192 | } 193 | 194 | ``` 195 | ### 性能优化 196 | 1. 避免频繁setState 197 | 198 | 由于微信小程序逻辑层和视图层各自独立，两边的数据传输是靠转换后的字符串。因此当setData频率过快，内容庞大时，会导致阻塞。由于本项目又涉及很多的手势操作，touchmove事件的频率很快，所以项目早期时候，在安卓系统下卡顿十分明显。 199 | 200 | 优化方式有：通过做函数节流，降低setData频次；将页面无关的数据不要绑定到data上，而是绑定到组件实例上（牺牲运算效率换取空间效率）。 201 | 202 | 使用微信的自定义组件，也是一个很大的提升因素，个人认猜测可能是自定义组件内部data的改变不会导致其他组件或页面的data更新。项目早期采用的是wepy框架，由于历史局限性（当时微信还未公布自定义组件方案），所以效率问题一直很是头疼。好在Taro框架通过编译的方式完美的支持了这个方案。 203 | 204 | 2. 归并setState 205 | 206 | 例如，当图片加载，获取到原始尺寸后，需要计算出该图片在当前场景下的预设尺寸和位置。必须先计算出自适应后的宽高，然后才能计算出预设的偏移量。因此可以将尺寸和位置参数都计算完毕后，再调用setState更新视图，这样不仅降低了频次，同时也解决了图片闪烁的bug. 207 | 208 | 3. 利用缓存 209 | 210 | 前面有提到过利用缓存模块来存储组件状态或资源信息，在此不再赘述。 211 | 212 | ### 心得 213 | Taro框架采取的是一种编译的方式，将源代码分别编译出可以在不同端（微信/百度/支付宝/字节跳动小程序、H5、React-Native 等），因此可以在性能上与各个平台保持一致。 214 | 215 | 而mpvue的方案则是修改vue的runtime，将vue 实例与小程序 Page 实例建立关联以及生命周期的绑定。私以为，这种通过映射的方式可能会导致通信效率上的降低，并且vue和微信又各自独立迭代，后期的协调也越来越费劲，所以个人感觉上，还是Taro的方案略胜一筹。个人薄见，还请海涵。 216 | 217 | ### 写在最后 218 | - Github 219 | 220 |
