Vue Unsaved Changes Dialog

A beautiful unsaved changes dialog, inspired by a component from the Squarespace admin.

Live demo ›

  • Save, Discard, and Cancel buttons
  • On desktop, popup appears precisely underneath the mouse cursor
  • Smoothly animates in and out
  • Popup intelligently avoids the window edges and responds to window resizing
  • Full responsive: renders as in full-screen on mobile
  • Keyboard navigable/accessible
  • All text is replaceable

More goodies

  • Includes buttery animations for both desktop and mobile
  • Mouse listener is throttled to avoid performance issues (bundles lodash.throttle, an extra 2KB)
  • All listeners are deactivated when component is torn down
  • Darkens background
  • Clicking the background dismisses the dialog (same as cancel button)
  • Bundles desktop, mobile, popup positioning logic, and all styles and animations in 14KB
  • No dependencies

Install

npm i vue-unsaved-changes-dialog

Usage

<button @click="attemptToGoBack">Back</button>

<UnsavedChangesDialog
  :title="Unsaved Changes"
  :subtitle="['You have unsaved changes', 'Would you like to save or discard them?']"
  :show="shouldShowDialog"
  @cancel="closePopup"
  @discard="discard"
  @save="save"/>

Detailed use case:

import UnsavedChangesDialog from 'vue-unsaved-changes-dialog';

export default {
  name: 'App',
  data() {
    return {
      shouldShowDialog: false,
    }
  },
  methods: {
    attemptToGoBack() {
      this.hasUnsavedChanges ? 
        this.showPopup() :
        this.exit();
    },
    exit() {
      this.closePopup();
      // and leave the view
    },
    showPopup() {
      this.shouldShowDialog = true;
    },
    closePopup() {
      this.shouldShowDialog = false;
    },
    discard() {
      this.discardEdits();
      this.exit();
    },
    discardEdits() {
      // your code here
    },
    async save() {
      try {
        await this.saveChangesToServer();
        this.exit();
      } catch(e) {
        console.error(e);
      }
    },
    async saveChangesToServer() {
      // your code here
    }
  },
  computed: {
    hasUnsavedChanges() {
      // check for unsaved changes
    }
  },
  components: {
    UnsavedChangesDialog
  }
}

Customizing

Text

The title and body text can be customized with props:

<UnsavedChangesDialog
  :title="Unsaved Changes"
  :subtitle="['You have unsaved changes', 'Would you like to save or discard them?']"
 />

subtitle accepts both Strings and String Arrays. If an array is supplied, a <p> element will be inserted for every one.

Button text & icons

The buttons can be customized using the slots API. You can inject your own text, icons, html, etc. into any part of the dialog.

<UnsavedChangesDialog
  :title="Unsaved Changes">
  <template name="title">Destory the things?</template>
  <template name="body">Description</template>
  <template name="cancel-button"></template>
  <template name="discard-button">💀</template>
  <template name="save-button"></template>
</UnsavedChangesDialog>

Styles & Animations

To use your own styles, use the unstyled build (no-css.esm.js). You can copy the default styles (no-css.esm.css) into your project and customize it.

Builds

There are 5 files in the dist directory:

Extension Use case Notes
.esm.js Standard ES6 module Default build, for use in a Vue CLI project. Already minified for production
no-css.esm.js Standard ES6 module without styling ES6 build with all styles extracted to a separate .esm.css file for customization/overriding
no-css.esm.css CSS styles for the unstyled ES6 build Copy this into your project to customize the UI
.min.js Browser build, requires no build system. This is the file you'd get from the UNPKG cdn
.ssr.js Rollup build for use with SSR. Honestly, I'm not sure what it is, but it was in the rollup template I used.

Live Development

You'll need NPM and the Vue CLI.

npm install 
npm run serve

Building

You'll need to install Rollup.js to run the build script. Install it with npm install --g rollup

npm run build

Running the build script generate main (.ssr.js), module (.esm.js), and unpkg (.min.js) versions in the dist directory.
