Vue Promise Dialogs

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

Why?

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

Install

From version 2.0.0 it works for Vue 2 and Vue 3 within a single package by the power of vue-demi 🔥

Vue 3

npm install vue-promise-dialogs

Vue 2

npm install vue-promise-dialogs @vue/composition-api

Usage

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"

interface BooleanDialogParams {
    text: string;
}

const BooleanDialog = defineComponent({
    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>
      </div>
    `,
    props: {
        params: {
            type: Object as PropType<BooleanDialogParams>,
            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<BooleanDialogParams, 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' });

Unmount delay

By default, a dialog is unmounted immediately right after resolve/reject, but maybe you want to change this behaviour, for example, to play the close animation.

You have two options here:

1. Specify the unmount delay (in ms) using unmountDelay prop in PromiseDialogsWrapper.
2. Specify the unmount delay (in ms) as a second argument when emitting resolve/reject event. This option will override unmountDelay prop if both are provided.

Close all

In some cases you may want to close all opened dialogs. For example, on route change.

You can use closeAllDialogs for this. All you need is to set a reason, which will be used in promises reject.

TODO

• Fallback to mount dialogs without PromiseDialogsWrapper
