uni-ttLive: short video based on uniapp+uViewUI + live chat example

1. Project overview

uniapp-ttlive uni-app+uview-ui+vue.js+uapopup short video/live/chat project based on 061480e5c8cd69 and other technologies mixed and developed. Supports full-screen immersion, sliding up and down to switch videos and other functions.

Second, the preview effect

As shown in the figure below: Compile effect on h5, applet and APP

Three, coding technology

• Encoder/technology: HbuilderX3.1.21+Uniapp+Nvue+Vuex+Uapopup
• UI component library: uView-ui / uni-ui
• Vector icon library: iconfont font icons
• Pop-up component: UApopup is based on uni-app encapsulation of cross-end pop-up component
• Custom navigation bar + bottom menu bar
• Compilation support: H5 + applet + APP

Four, functional characteristics

✅ Support full-screen immersive transparent mode
✅ Smooth up and down sliding experience
✅ Mini time progress bar
✅ Custom components support Nvue page

Five, directory structure/compilation

The component library used in the project is uview-ui , a multi-platform UI framework for rapid development.

main.js configuration

import Vue from 'vue'
import App from './App'

import uView from 'uview-ui'
Vue.use(uView)

import API from '@/common/request'
Vue.prototype.$api = API

// 引入状态管理
import Store from './store'
Vue.prototype.$store = Store

Vue.config.productionTip = false
App.mpType = 'app'

// #ifdef APP-PLUS
plus.navigator.closeSplashscreen()
// #endif

const app = new Vue({
    ...App
})
app.$mount()

Considering that the Nvue page does not support global mounting of prototype prototypes, use globalData to control it instead.
