wix-cli-dashboard-modal

name	wix-cli-dashboard-modal
description	Use when adding popup forms, confirmations, or detail views to Wix dashboards; creating reusable dialog components across dashboard pages; showing context-specific information in overlays; opening modals from dashboard pages; or passing data between dashboard pages and modals. Do NOT use for static content (use dashboard pages instead) or site-facing UI (use site widgets/embedded scripts).
compatibility	Requires Wix CLI development environment.

Overview

Dashboard modals are popup dialogs triggered from dashboard pages or plugins. They consist of three files and use the Dashboard SDK for lifecycle control via openModal() and closeModal().

Quick Reference

Task	Method	Example
Create modal	Create 3 files in src/dashboard/modals/<folder>/	See File Structure below
Open modal	dashboard.openModal()	openModal({ modalId: "modal-id" })
Pass data to modal	params in openModal()	params: { userId: "123" }
Read data in modal	observeState()	dashboard.observeState((state) => { ... })
Close modal	dashboard.closeModal()	closeModal()
Return data to parent	Pass data to closeModal()	closeModal({ ... })
Wait for modal close	modalClosed Promise	const { modalClosed } = openModal(...);

File Structure

Create three files in src/dashboard/modals/<folder-name>/:

1. extensions.ts - Builder configuration with modal ID, title, dimensions, component path
2. <modal-name>.tsx - React component rendering modal content
3. <modal-name>.config.ts - Configurable modal properties (title, width, height)

Implementation

Creating a Modal

Create the three required files:

1. extensions.ts - Modal builder configuration:

import { extensions } from '@wix/astro/builders';
import config from './<modal-name>.config.ts';

export default extensions.dashboardModal({
  id: "{{GENERATE_UUID}}",
  title: config.title,
  width: config.width,
  height: config.height,
  component: './extensions/dashboard/modals/<modal-name>/<modal-name>.tsx',
});

CRITICAL: UUID Generation

The id must be a unique, static UUID v4 string. Generate a fresh UUID for each extension - do NOT use randomUUID() or copy UUIDs from examples. Replace {{GENERATE_UUID}} with a freshly generated UUID like "a1b2c3d4-e5f6-7890-abcd-ef1234567890".

Builder fields:

Field	Type	Description
id	string	Unique modal ID (GUID). Used with openModal()
title	string	Modal title shown in project dashboard
width	number	Initial width while loading
height	number	Initial height while loading
component	string	Path to the modal content .tsx file

2. <modal-name>.tsx - Modal content component:

import type { FC } from 'react';
import { dashboard } from '@wix/dashboard';
import {
  WixDesignSystemProvider,
  Text,
  Box,
  CustomModalLayout,
} from '@wix/design-system';
import '@wix/design-system/styles.global.css';
import config from './<modal-name>.config.ts';

const { width, height, title } = config;

// To open your modal, call `openModal` with your modal id.
// e.g.
// import { dashboard } from '@wix/dashboard';
// function MyComponent() {
//   return <button onClick={() => dashboard.openModal({ modalId: '8ef4d434-9c80-44f5-a3f5-6f15f3a34be7' })}>Open Modal</button>;
// }
const Modal: FC = () => {
  return (
    <WixDesignSystemProvider features={{ newColorsBranding: true }}>
      <CustomModalLayout
        width={width}
        maxHeight={height}
        primaryButtonText="Save"
        secondaryButtonText="Cancel"
        = => dashboard.closeModal()}
        secondaryButtonOnClick={() => dashboard.closeModal()}
        title={title}
        subtitle="Edit this file to customize your modal"
        content={
          
            Wix CLI Modal
          
        }
      />
    
  );
};

  ;

3. <modal-name>.config.ts - Configurable properties:

export default {
  title: "My Modal",
  width: 600,
  height: 400,
};

Then register in src/extensions.ts:

import { dashboardmodalYourModal } from './dashboard/modals/<modal-name>/extensions.ts';

export default app()
  .use(dashboardmodalYourModal)
  // ... other extensions

Opening a Modal

import { dashboard } from "@wix/dashboard";

// Simple open
const result = await dashboard.openModal({
  modalId: "your-modal-id", // From .extension.ts id field
});

// Pass data to modal via params
const result = await dashboard.openModal({
  modalId: "your-modal-id",
  params: {
    userId: user.id,
    itemData: complexObject, // Objects are passed directly, no encoding needed
  },
});

// Get notified when the modal is closed
const { modalClosed } = dashboard.openModal({
  modalId: "your-modal-id",
});
const result = await modalClosed; // Resolves with data from closeModal()

Receiving Data in Modal

Use observeState() to access data passed via params in openModal():

import { dashboard } from "@wix/dashboard";
import { useEffect, useState } from "react";

function MyModal() {
  const [modalData, setModalData] = useState<{ userId?: string; itemData?: any }>({});

  useEffect(() => {
    dashboard.observeState((state) => {
      // Access custom data passed through openModal params
      if (state.userId) {
        setModalData({
          userId: state.userId,
          itemData: state.itemData,
        });
      }
    });
  }, []);

  return <div>User ID: {modalData.userId}</div>;
}

Closing Modal

Call closeModal() from within the modal extension to close it. Optionally pass data back to the opener.

import { dashboard } from "@wix/dashboard";

// Close without returning data
dashboard.closeModal();

// Close with custom return data
dashboard.closeModal({ saved: true, itemId: "123" });

Parameter	Type	Description
closeData	Serializable (optional)	Data to pass back to the modal opener. Must be cloneable via structured clone algorithm.

Supported types: strings, numbers, booleans, plain objects, arrays, Dates, Maps, Sets, ArrayBuffers. Not supported: functions, DOM nodes, class instances with methods, Symbols, Promises.

Returns: void

Customizing Modal

Edit .config.ts for organized settings:

export default {
  title: 'User Settings',
  width: 600,
  height: 500,
}

Import in .tsx:

import config from './modal.config.ts';

export default function MyModal() {
  return (
    <CustomModalLayout
      title={config.title}
      // ... rest of component
    />
  );
}

Common Mistakes

Mistake	Fix
Can't find modal ID	Check .extension.ts file's id field
Forgetting to register in extensions.ts	Import and .use() the modal
Using extensionId instead of modalId	Use modalId in openModal()
Can't access params in modal	Use dashboard.observeState() to read passed data
Modal won't close	Use dashboard.closeModal() from @wix/dashboard

Real-World Example

// Dashboard Page: Opening edit modal
const handleEdit = async (item: Item) => {
  dashboard.openModal({
    modalId: "edit-item-modal-guid",
    params: {
      itemId: item._id,
      item: item, // Objects passed directly via params
    },
  });
};

// Modal: Receiving and saving data
export default function ItemEditModal() {
  const [formData, setFormData] = useState<Item | null>(null);

  useEffect(() => {
    dashboard.observeState((state) => {
      if (state.item) {
        setFormData(state.item);
      }
    });
  }, []);

  const handleSave = async () => {
    // Save logic
    dashboard.showToast({ message: "Saved!", type: "success" });
    dashboard.closeModal();
  };

  return (
    <CustomModalLayout
      title="Edit Item"
      =
      = => dashboard.closeModal()}
      primaryButtonOnClick={handleSave}
      content={/* form fields */}
    />
  );
}

Verification

After implementation, use wix-cli-app-validation to validate TypeScript compilation, build, preview, and runtime behavior.
