Generate LN invoices on static sites without revealing your NWC secret.
Problem:
There are excellent JS libraries for working with #NWC, like @Alby 's js-sdk. The problem is that they're only suitable for working with the site user's wallet. But what if I want to generate #Lightning invoices on my site, for example, to collect donations? This requires a service layer on the backend, because if you simply generate invoices via NWC on the frontend, you'd have to expose your NWC secret.
Solution:
Therefore, I created a simple microservice where you can insert your NWC secret and get a unique endpoint for generating invoices on demand! To generate invoices, you just need to add a simple JS script to your static site that will call the received API method.
Instructions:
1. Visit the website:
2. Insert your NWC secret (you can limit NWC to only invoice creation rights or set a minimum budget for security)
3. Get example code and a URL that when called generates a Lightning invoice for the specified amount
4. Insert the script into your site
5. Enjoy
The integration example provided is very simple, so you may need to enhance it slightly to achieve the necessary functionality. Any AI can easily handle this, but feel free to contact me if you need help with installation!
The service doesn't charge any fees — all invoices are generated directly by your Lightning wallet.
By the way, you can even deploy this service on your own server — it only requires Node.js.
Here's the GitHub repo: 
You can see an example of the script working on @Bitcoin Calendar's website. Just click on the “zap” button.
