Key Concepts

App Lifecycle

javascript
App({
  onLaunch(options) {
    // Mini Program initialized
  },
  onShow(options) {
    // Mini Program shown
  },
  onHide() {
    // Mini Program hidden
  },
  globalData: {
    userInfo: null
  }
})

Page Lifecycle

javascript
Page({
  data: {
    message: 'Hello World'
  },
  onLoad(options) {
    // Page loaded
  },
  onShow() {
    // Page shown
  },
  onReady() {
    // Page ready
  },
  onHide() {
    // Page hidden
  },
  onUnload() {
    // Page unloaded
  }
})

WXML Data Binding

wxml
<view>{{message}}</view>
<view wx:if="{{condition}}">Conditional</view>
<view wx:for="{{array}}" wx:key="id">{{item}}</view>

Event Handling

wxml
<button bindtap="handleTap">Click Me</button>
javascript
Page({
  handleTap(e) {
    console.log(e)
  }
})
