taro-chatroom是基於Taro多端實例聊天項目,運用Taro+react+react-redux+taroPop+react-native等技術開發的仿微信App界面聊天室,實現了發送消息/emoj表情、gif表情大圖、圖片預覽、發紅包、動態圈等功能。css
編譯到H5端、小程序、App端效果以下:(後續大圖均爲APP端)html

taro本地存儲使用的是異步存儲,因爲同步存儲不支持RN端web
/** * @desc Taro本地存儲 */ import Taro from '@tarojs/taro' export default class Storage { static get(key) { return Taro.getStorage({ key }).then(res => res.data).catch(() => '') } static set(key, data){ return Taro.setStorage({key: key, data: data}).then(res => res) } static del(key){ Taro.removeStorage({key: key}).then(res => res) } static clear(){ Taro.clearStorage() } }
如不但願編譯到RN端,使用以下包裹便可redux
/*postcss-pxtransform rn eject enable*/ 小程序
/*postcss-pxtransform rn eject disable*/ react-native
對於一些RN端不兼容樣式,邊框、超過多行...,需特殊樣式處理微信
/* * 對於不兼容的樣式,如RN不兼容border-right,能夠經過mixin統一處理 */ /** * RN 不支持針對某一邊設置 style,即 border-bottom-style 會報錯 * 那麼 border-bottom: 1px 就須要寫成以下形式: border: 0 style color; border-bottom-width: 1px; */ @mixin border($dir, $width, $style, $color) { border: 0 $style $color; @each $d in $dir { #{border-#{$d}-width}: $width; } } /** * NOTE RN 沒法經過 text-overflow 實現省略號,這些代碼不會編譯到 RN 中 */ @mixin ellipsis { /*postcss-pxtransform rn eject enable*/ overflow: hidden; white-space: nowrap; text-overflow: ellipsis; /*postcss-pxtransform rn eject disable*/ } /** * NOTE 實現多行文本省略,RN 用 Text 標籤的 numberOfLines={2},H5/小程序用 -webkit-line-clamp */ @mixin clamp($line) { /*postcss-pxtransform rn eject enable*/ display: -webkit-box; overflow: hidden; -webkit-line-clamp:$line; /* autoprefixer: ignore next */ -webkit-box-orient: vertical; /*postcss-pxtransform rn eject disable*/ } /** * 對於不能打包到 RN 的樣式,能夠用 postcss 方式引入 */ @mixin eject($attr, $value) { /*postcss-pxtransform rn eject enable*/ #{$attr}: $value; /*postcss-pxtransform rn eject disable*/ }
◆ Taro聊天實現消息滾動到底部app
在taro中實現聊天消息滾動到最底部,因爲RN端不支持 createSelectorQuery,如是作了兼容處理。
componentDidMount() { if(process.env.TARO_ENV === 'rn') { this.scrollMsgBottomRN() }else { this.scrollMsgBottom() } }
// 滾動至聊天底部 scrollMsgBottom = () => { let query = Taro.createSelectorQuery() query.select('#scrollview').boundingClientRect() query.select('#msglistview').boundingClientRect() query.exec((res) => { // console.log(res) if(res[1].height > res[0].height) { this.setState({ scrollTop: res[1].height - res[0].height }) } }) } scrollMsgBottomRN = (t) => { let that = this this._timer = setTimeout(() => { that.refs.ScrollViewRN.scrollToEnd({animated: false}) }, t ? 16 : 0) }
聊天中表情使用的是emoj表情符,若是使用圖片作表情也是能夠,不過須要一些特殊匹配處理 :12) [:高興],使用emoj就相對簡單些罷了。
// 渲染消息記錄 renderMsgTpl = (data) => { return data.map((item, index) => ( <View key={index}> {item.msgtype == 1 && <View className="msgitem msg__time"><Text className="msg__text">{item.msg}</Text></View> } {item.msgtype == 2 && <View className="msgitem msg__notice"><Text className="msg__text">{item.msg}</Text></View> } {item.msgtype == 3 && <View className="msgitem"> {!item.isme ? <View className="msg__avator"><Image className="msg__avator-img" src={item.avator} mode="aspectFit" /></View> : null} <View className={`msg__cntbox ${item.isme ?
