npm i -S nuxt-property-decoratorThere are 6 decorators:
@Inject@Model@Prop@Provide@Watch@Component(exported fromvue-class-component)
import { Component, Inject, Model, Prop, Vue, Watch } from 'nuxt-property-decorator'
const s = Symbol('baz')
@Component({
components: { comp }
})
export class MyComponent extends Vue {
@Inject() foo!: string
@Inject('bar') bar!: string
@Inject(s) baz!: string
@Model('change') checked!: boolean
@Prop()
propA!: number
@Prop({ default: 'default value' })
propB!: string
@Prop([String, Boolean])
propC!: string | boolean
@Prop({ type: null })
propD!: any
@Provide() foo = 'foo'
@Provide('bar') baz = 'bar'
@Watch('child')
onChildChanged(val: string, oldVal: string) { }
@Watch('person', { immediate: true, deep: true })
onPersonChanged(val: Person, oldVal: Person) { }
}is equivalent to
const s = Symbol('baz')
export const MyComponent = Vue.extend({
name: 'MyComponent',
components: { comp },
inject: {
foo: 'foo',
bar: 'bar',
[s]: s
},
model: {
prop: 'checked',
event: 'change'
},
props: {
checked: Boolean,
propA: Number,
propB: {
type: String,
default: 'default value'
},
propC: [String, Boolean],
propD: { type: null }
},
data () {
return {
foo: 'foo',
baz: 'bar'
}
},
provide () {
return {
foo: this.foo,
bar: this.baz
}
}
methods: {
onChildChanged(val, oldVal) { },
onPersonChanged(val, oldVal) { }
},
watch: {
'child': {
handler: 'onChildChanged',
immediate: false,
deep: false
},
'person': {
handler: 'onPersonChanged',
immediate: true,
deep: true
}
}
})As you can see at propA and propB, the type can be inferred automatically when it's a simple type. For more complex types like enums you do need to specify it specifically.
Also this library needs to have emitDecoratorMetadata set to true for this to work.
