Vue Promise Dialogs

A tiny & modern library that allows you to work with dialogs as with asynchronous functions.


Because many dialogs work exactly as promises.
They are opened (called) and then closed with some result (resolved) or canceled (rejected).


npm install --save vue-promise-dialogs

Or for a CDN version, you can use it on


Main requirements:

  1. You should mount exactly one PromiseDialogsWrapper somewhere in your application root.
  2. The dialog component should accept params props.
  3. The dialog component should emit resolve or reject events when the user makes a decision.
import { createPromiseDialog } from "vue-promise-dialogs"

const BooleanDialog = Vue.extend({
    template: `
      <div class="dialog">
          <p>{{ params.text }}</p>
          <button name="true" @click="$emit('resolve', true)">True</button>
          <button name="false" @click="$emit('resolve', false)">False</button>
          <button name="cancel" @click="$emit('reject', 'cancel')">Cancel</button>
    props: {
        params: {
            type: Object,
            required: true,

// First type argument is the type of params prop that will be passed to component
// Second type argument is the type of value with which the promise will be fulfilled
const openDialog = createPromiseDialog<{ text: string }, boolean>(BooleanDialog);

// When you call this function, dialog will be mounted to `PromiseDialogsWrapper`.
// When user press any button and resolve/reject event emitted, promise will be settled and dialog will be destroyed.
const result: boolean = await openDialog({ text: 'Some text' });

Vue Class Component Example

If you're using Vue Class Component to define your dialog components, you can extend them from BasePromiseDialog.
This will allow you to avoid defining type arguments in createPromiseDialog.
BasePromiseDialog already defines params prop and methods resolve/reject, so you don't have to.

import { Component } from "vue-class-component"
import { BasePromiseDialog, createPromiseDialog } from "vue-promise-dialogs"

    template: `
      <div class="dialog">
          <p>{{ params.text }}</p>
          <button name="true" @click="onTrue">True</button>
          <button name="false" @click="onFalse">False</button>
          <button name="cancel" @click="onCancel">Cancel</button>
// You need to extend your component from BasePromiseDialog with correct type arguments
class BooleanDialog extends BasePromiseDialog<{ text: string }, boolean> {
    onTrue() {

    onFalse() {

    onCancel() {

// You don't have to specify type arguments because they are inferenced from BooleanDialog
const openDialog = createPromiseDialog(BooleanDialog);

const result: boolean = await openDialog({ text: 'Some text' });
