Enhance Vuetify functionality using TypeScript for custom components

I'm facing a challenge with extending a Vuetify component and setting default props in TypeScript. While I had success doing this in JavaScript, I am struggling to do the same in TS. Below is an example of how the Component was implemented in JS:

import { VTextField } from 'vuetify/lib'

export default {
  name: "my-text-field",
  extends: VTextField,
  props: {
      "hide-details": {
        type: Boolean,
        default: true
      },
      outlined: {
        type: Boolean,
        default: true
      },
      dense: {
        type: Boolean,
        default: true
      },
      "single-line": {
        type: Boolean,
        default: true
      },
      color: {
        type: String,
        default: "secondary"
      }
  }
}

To properly incorporate this feature, make sure to update the tsconfig.json file with the following code:

// tsconfig.json

{
  "compilerOptions": {
    "types": ["vuetify"]
  }
}

Then, simply extend the necessary component like so:

<script lang="ts">
import { VTextField } from 'vuetify/lib'

import { Component,  Prop } from 'vue-property-decorator'

@Component({})
export default class CustomTextField extends VTextField {
    @Prop({default: 'auto'}) private hideDetails!: boolean|string;
    @Prop({default: true}) private outlined!: boolean;
    @Prop({default: true}) private dense!: boolean
    @Prop({default: true}) private singleLine!: boolean;
    @Prop({default: 'secondary'}) private color!: string
}
</script>

Answer №2

After studying the VTextArea component of Vuetify, I was able to come up with a solution that worked for me:

import Vue from 'vue'
//@ts-ignore
import VTextField from 'vuetify/lib/components/VTextField/VTextField'

// Implementing Base Mixins and Defining Custom Properties
const base = Vue.extend({ mixins: [VTextField] })
export default base.extend({
  name: "my-text-field",
  props: {
      hideDetails: {
        type: Boolean,
        default: true
      },
      outlined: {
        type: Boolean,
        default: true
      },
      dense: {
        type: Boolean,
        default: true
      },
      singleLine: {
        type: Boolean,
        default: true
      },
      color: {
        type: String,
        default: "secondary"
      }
  }
})

Check this out:

import {Vue, Component, Prop} from 'vue-property-decorator';
import { VIcon, VTextField} from 'vuetify/lib'


interface Item {
    name: string;
    completed: boolean;
}

@Component({
    name: 'TaskItem',
    components: {
        'v-icon': VIcon,
         'v-text-field': VTextField
    }
})
export default class TaskItem extends Vue {

    @Prop(Object) public task!: Item;
    @Prop(Number) public number!: number;
    @Prop(Number) public editId!: number;

    public modifiedContent = 'hello';

    public modify() {
        this.$emit('on-modify', this.number)
    }

    public persist() {
        alert('ok');
    }


    protected render() {
        return (
            <li>
                {this.editingId === this.index ?
                    (<div>
                        {/* tslint:disable-next-line:max-line-length */}
                        <v-text-field v-model={this.modifiedContent} append-icon={'mdi-close'} placeholder={this.task.name} on-click:append={this.persist}/>
                        {/*<v-text-field><v-icon color={'red'} slot={'append'}>mdi-close</v-icon></v-text-field>*/}
                    </div>)
                    : (<div>
                            <span>{this.task.text}</span>
                            <v-icon x-small={true} nativeOn-click={this.modify}>mdi-pencil</v-icon>
                        </div>)
                }
            </li>
        );
    }
}
