InOut typescript decorator for vuejs component

Install:

npm install --save vue-inout-prop-decorator

Exemple with InOut annotation:

child component

<template>
    <div>
        <p>Value1: {{ value1 }}</p>
        <p>Value2: {{ value2 }}</p>
        <button @click="change" ></button>
    </div>
</template>

<script lang="ts">
    import {Component, Vue} from 'vue-property-decorator';
    import {InOut} from "vue-inout-prop-decorator";
    
    @Component
    export default class ParentComponent extends Vue {
        
        @InOut() value1: string;
        @InOut({ type: String, default: "World" }) value2: string;
        
        change() {
            this.value1 = "Ho ho ho!";
            this.value2 = "Ha ha ha!";
        }
        
    }
</script>

parent component

<template>
    <div>
        <p>Value: {{ value }}</p>
        <my-child :value1.sync="value" ></my-child>
    </div>
</template>

<script lang="ts">
    import {Component, Vue} from 'vue-property-decorator';
    import MyChild from './MyChild.vue';
    
    @Component({
        components: {
            MyChild,
        }
    })
    export default class ParentComponent extends Vue {
        value: string = 'hello';		
    }
</script>

Exemple WITHOUT InOut annotation:

<template>
    <div>
        <p>Value1: {{ value1_val }}</p>
        <p>Value2: {{ value2_val }}</p>
        <button @click="change" ></button>
    </div>
</template>

<script lang="ts">
    import {Component, Prop, Vue, Watch} from 'vue-property-decorator';
    import {InOut} from "vue-inout-prop-decorator";
    
    @Component
    export default class CustomInput extends Vue {
        
        @Prop() value1: string;
        @Prop({ type: String, default: "World" }) value2: string;
        
        change() {
            this.updateValue1("Ho ho ho!");
            this.updateValue2("Ha ha ha!");
        }
        
        value1_val: string = null;
        value2_val: string = null;
        
        @Watch('value1')
        @Watch('value2')
        mounted() {
            this.value1_val = this.value1;
            this.value2_val = this.value2;
        }
        
        @Emit('update:value1')updateValue1(value:  boolean) { this.value1_val = value; }
        @Emit('update:value2')updateValue2(value:  boolean) { this.value2_val = value; }
        
        
    }
</script>

Exemple V-Model

<template>
    <div>
        <button @click="value = 'new Val'" >Change Value</button>
    </div>
</template>

<script lang="ts">
    import {Component, Vue} from 'vue-property-decorator';
    import {InOut} from "vue-inout-prop-decorator";
    
    @Component
    export default class ParentComponent extends Vue {
        @InOut({isVModel: true}) value: string;		
    }
</script>
