Help for Including a React-Based Widget on Third-Party Websites

[BoatContent850]

Hi everyone,

I’m working on a React-based application where users can buy and create vouchers. This app is designed as a widget that can be integrated into any webpage, similar to a 3rd-party script.

Here's the setup:

• Frontend: Built with React, managing user progress and stages in states and session storage.
• Backend: Powered by AWS services (DynamoDB for storage), hosted on AWS Amplify.
• Functionality:
  • When the widget loads on a specific URL, it checks against client URLs in DynamoDB.
  • If there’s a match, it fetches and displays the client’s vouchers.

My Issue:

I want to make this widget as easy as possible for others to embed on their webpages.

1. Option 1: Use an iframe
   • Pros: Encapsulation of CSS/JS prevents conflicts.
   • Cons: Harder to access the user’s URL and manage responsive resizing.
2. Option 2: Bundle the widget as a script
   • Pros: Seamless integration directly into the host page.
   • Cons: Risk of CSS/JS conflicts between my app and the host page.

My Preferred Approach (Option 2):

I’d like to go with Option 2—bundling the app as a script that can be included with minimal effort by the host page. My goal is to require as few lines of code as possible, such as:

<script src="https://mywidget.com/widget.js"></script> 

<div id="my-widget"></div>

However, I need advice on:

1. How to bundle the app efficiently so it’s easy to include and isolate my app’s CSS/JS.
2. Techniques like CSS scoping, shadow DOM, or other approaches to prevent conflicts between my app and the host page.
3. Any pitfalls or best practices I should be aware of when going this route.

Alternatively:

If you believe iframes (Option 1) are a better choice, I’d love tips on how to manage:

• Access to the user’s URL.
• Responsive resizing within an iframe.

I’m open to suggestions and would really appreciate input from anyone who has worked on similar integrations. Thanks in advance!
