@Component
export default class App extends Vue {
    // 初始化数据
    msg = 123

    // 声明周期钩子
    mounted () {
        this.greet()
    }

    // 计算属性
    get computedMsg () {
        return 'computed ' + this.msg
    }

    // 方法
    greet () {
        alert('greeting: ' + this.msg)
    }
}

import { Component, Emit, Inject, Model, Prop, Provide, Vue, Watch } from 'vue-property-decorator'

@Component
export class MyComponent extends Vue {
  
  @Prop()
  propA: number = 1

  @Prop({ default: 'default value' })
  propB: string

  @Prop([String, Boolean])
  propC: string | boolean

  @Prop({ type: null })
  propD: any

  @Watch('child')
  onChildChanged(val: string, oldVal: string) { }
}

上面代码相当于
export default {
  props: {
    checked: Boolean,
    propA: Number,
    propB: {
      type: String,
      default: 'default value'
    },
    propC: [String, Boolean],
    propD: { type: null }
  }
  methods: {
    onChildChanged(val, oldVal) { }
  },
  watch: {
    'child': {
      handler: 'onChildChanged',
      immediate: false,
      deep: false
    }
  }
}
