Getting Started

Installation

Prerequisites

Before you begin, ensure you have:

Node.js v22.x or higher installed on your system
npm or yarn package manager
A text editor (VS Code recommended for the best development experience)
Basic JavaScript knowledge and familiarity with modern web development

Step 1: Set Up Your Project

Create a new directory for your extension project and initialize it:

bash

mkdir extension-starter
cd extension-starter
npm init -y

Expected result: A new package.json file will be created in your directory.

Step 2: Install the Extensions SDK

Install the Stripo Editor Extensions SDK:

bash

npm install @stripoinc/ui-editor-extensions

For development, you will also need a bundler. We recommend using Vite:

bash

npm install --save-dev vite

Expected result: The packages will be installed in the node_modules directory and listed in your package.json dependencies.

Step 3: Create Your Project Structure

Create the following file structure:

bash

extension-starter/
├── index.html
├── src/
│   ├── creds.js
│   ├── index.js
│   └── extension.js
├── package.json
└── vite.config.js

Create each file with the following content:

Create `index.html`:

html

<!DOCTYPE html>
<html lang="en">
<head>
    <meta charset="UTF-8">
    <title>Stripo Plugin</title>
    <style>

<!-- Vite will replace this with the correct script dynamically -->
<script type="module" src="/src/index.js"></script>
</body>
</html>

Create `vite.config.js`:

javascript

import { defineConfig } from 'vite';

export default defineConfig({
    server: {
        port: 3000
    }
});

Create `src/creds.js`:

Important

Replace the placeholder values YOUR_PLUGIN_ID and YOUR_SECRET_KEY with your actual plugin credentials.

javascript

export const PLUGIN_ID = 'YOUR_PLUGIN_ID';
export const SECRET_KEY = 'YOUR_SECRET_KEY';

export const EDITOR_URL = 'https://plugins.stripo.email/resources/uieditor/latest/UIEditor.js';

export const USER_ID = '1';
export const EMAIL_ID = `${PLUGIN_ID}_${USER_ID}_1`;

Step 4: Create Your First Extension

Create `src/extension.js`:

javascript

import { ExtensionBuilder } from '@stripoinc/ui-editor-extensions';

// Create your first extension
const extension = new ExtensionBuilder()
    // Add custom styles to change the blocks panel background
    .addStyles(`
        .block-thumb {
            background-color: #33CC4D
        }
    `)
    .build();

export default extension;

What's happening here:

We import the ExtensionBuilder from the SDK
We create an extension using the builder pattern for clean, readable code
We add custom CSS styles that will be injected into the editor interface
We build and export the extension for use in the editor initialization

Step 5: Initialize the Editor

Create `src/index.js`:

javascript

import extension from './extension.js';
import { PLUGIN_ID, SECRET_KEY, EDITOR_URL, EMAIL_ID, USER_ID } from './creds';

// Load the Stripo editor script dynamically
function loadStripoEditor() {
    const script = document.createElement('script');
    script.id = 'UiEditorScript';
    script.src = EDITOR_URL;
    script.type = 'module';
    script.onload = _initializeEditor;
    document.head.appendChild(script);
}

// Initialize the editor with a demo template
function _initializeEditor() {
    _loadDemoTemplate(template => {
        _runEditor(template, extension);
    });
}

// Run the editor with the provided template and extension
function _runEditor(template, extension) {
    window.UIEditor.initEditor(
        document.querySelector('#stripoEditorContainer'),
        {
            html: template.html,
            css: template.css,
            metadata: {
                emailId: EMAIL_ID
            },
            locale: 'en',
            onTokenRefreshRequest: function (callback) {
                _request('POST', 'https://plugins.stripo.email/api/v1/auth',
                    JSON.stringify({
                        pluginId: PLUGIN_ID,
                        secretKey: SECRET_KEY,
                        userId: USER_ID,
                        role: 'user'
                    }),
                    function(data) {
                        callback(JSON.parse(data).token);
                    }
                );
            },
            codeEditorButtonSelector: '#codeEditor',
            undoButtonSelector: '#undoButton',
            redoButtonSelector: '#redoButton',
            versionHistoryButtonSelector: '#versionHistoryButton',
            mobileViewButtonSelector: '#mobileViewButton',
            desktopViewButtonSelector: '#desktopViewButton',
            extensions: [
                extension
            ]
        }
    );
}

// Helper function to make HTTP requests
function _request(method, url, data, callback) {
    const req = new XMLHttpRequest();
    req.onreadystatechange = function () {
        if (req.readyState === 4 && req.status === 200) {
            callback(req.responseText);
        } else if (req.readyState === 4 && req.status !== 200) {
            console.error('Cannot complete request. Please check that you have entered valid PLUGIN_ID and SECRET_KEY values');
        }
    };
    req.open(method, url, true);
    if (method !== 'GET') {
        req.setRequestHeader('content-type', 'application/json');
    }
    req.send(data);
}

// Load a demo template from GitHub
function _loadDemoTemplate(callback) {
    _request('GET', 'https://raw.githubusercontent.com/ardas/stripo-plugin/master/Public-Templates/Basic-Templates/Trigger%20newsletter%20mockup/Trigger%20newsletter%20mockup.html', null, function(html) {
        _request('GET', 'https://raw.githubusercontent.com/ardas/stripo-plugin/master/Public-Templates/Basic-Templates/Trigger%20newsletter%20mockup/Trigger%20newsletter%20mockup.css', null, function(css) {
            callback({ html: html, css: css });
        });
    });
}

// Start loading when the page is ready
if (document.readyState === 'loading') {
    document.addEventListener('DOMContentLoaded', loadStripoEditor);
} else {
    loadStripoEditor();
}

Step 6: Add npm Scripts

Update your package.json with development scripts:

json

{
  "scripts": {
    "dev": "vite",
    "build": "vite build"
  }
}

Step 7: Run Your Extension

Start the development server:

bash

npm run dev

Open your browser and navigate to http://localhost:3000.

Expected result:

The Stripo editor loads successfully with your custom styles applied
The blocks panel displays thumbnails with your custom background color
Your extension is properly integrated and functioning

What You've Accomplished

Congratulations! You've successfully:

✅ Set up a development environment for Stripo extensions
✅ Created your first extension using ExtensionBuilder
✅ Added custom styles to the editor interface
✅ Initialized the editor with your custom extension
✅ Verified your changes are reflected in real-time

Common Issues and Solutions

Issue: Editor Does Not Load

Possible solutions:

Ensure the Stripo script URL is accessible and not blocked by network policies
Check the browser console for any JavaScript errors that might prevent loading
Verify that your plugin credentials are correct and valid

Issue: Styles Do Not Appear

Possible solutions:

Check for CSS syntax errors in your extension styles
Ensure the extension is properly registered in the editor configuration
Verify that CSS selectors are targeting the correct elements

Issue: Module Not Found Errors

Possible solutions:

Run npm install to ensure all dependencies are properly installed
Check that import paths are correct and match your file structure
Verify that the Stripo Extensions SDK is installed and up to date
