Declarative Usage (Recommended)

Use the open attribute to control visibility. Modal persists in DOM and can be reused.

Waiting for action...

<app-modal
  id="myModal"
  title="Confirm Delete"
  message="Are you sure you want to delete this item?"
  button1-text="Delete"
  button2-text="Cancel"
  button1-css="background: #ef4444;"
></app-modal>

<script>
  const modal = document.getElementById('myModal');

  // Show modal
  modal.open = true;

  // Listen for button events
  modal.addEventListener('modal-action1', () => {
    console.log('Deleted!');
  });
  modal.addEventListener('modal-action2', () => {
    console.log('Cancelled');
  });
</script>

Declarative with Slotted Content

Use slots for custom content instead of the message attribute.

<app-modal id="slottedModal" title="Custom Content" button1-text="Got it">
  <p>This content is <strong>slotted</strong> into the modal.</p>
  <ul>
    <li>Custom HTML</li>
    <li>Full flexibility</li>
  </ul>
</app-modal>

Programmatic Usage

Basic Modal

import { showModal } from '@manufosela/app-modal';

showModal({
  title: 'Hello!',
  message: 'Basic modal dialog.',
  button1Text: 'OK'
});

Confirmation Dialog

Waiting for action...

showModal({
  title: 'Confirm Action',
  message: 'Delete this item?',
  button1Text: 'Delete',
  button2Text: 'Cancel',
  button1Css: 'background: #ef4444;',
  button1Action: () => console.log('Deleted!'),
  button2Action: () => console.log('Cancelled.')
});

Three Button Modal

Waiting for action...

showModal({
  title: 'Save Changes?',
  message: 'You have unsaved changes.',
  button1Text: 'Save',
  button2Text: 'Discard',
  button3Text: 'Cancel',
  button1Css: 'background: #22c55e;',
  button2Css: 'background: #ef4444;',
  button1Action: () => console.log('Saved!'),
  button2Action: () => console.log('Discarded.'),
  button3Action: () => console.log('Cancelled.')
});

Custom Sizes

// Small modal
showModal({
  title: 'Small',
  message: 'Max-width 300px.',
  maxWidth: '300px',
  button1Text: 'OK'
});

// Large modal
showModal({
  title: 'Large',
  message: 'Max-width 600px.',
  maxWidth: '600px',
  button1Text: 'OK'
});

Without Header/Footer

// No header
showModal({
  message: 'No header.',
  showHeader: false,
  button1Text: 'Got it'
});

// No footer
showModal({
  title: 'No Footer',
  message: 'Close with X or Escape.',
  showFooter: false
});

Intercept Close

Use intercept-close to prevent auto-close and handle the close request externally.

Waiting for action...

<app-modal
  id="interceptModal"
  intercept-close
  modal-id="intercept-demo"
  title="Unsaved Changes"
  message="You have unsaved changes. Are you sure you want to close?"
  button1-text="Save & Close"
  button2-text="Discard"
></app-modal>

<script>
  const modal = document.getElementById('interceptModal');

  // Listen for close request (X button, Escape, overlay click)
  document.addEventListener('modal-closed-requested', (e) => {
    if (e.detail.modalId === 'intercept-demo') {
      // Ask for confirmation before closing
      if (confirm('Close without saving?')) {
        document.dispatchEvent(new CustomEvent('close-modal', {
          detail: { modalId: 'intercept-demo' }
        }));
      }
    }
  });
</script>

HTML Message

showModal({
  title: 'Rich Content',
  message: `
    <h3 style="margin:0">Features</h3>
    <ul>
      <li><strong>Bold</strong></li>
      <li><em>Italic</em></li>
    </ul>
  `,
  button1Text: 'Nice!'
});

This content is slotted into the modal.
