window.nostr.js

a small <script> you can drop in any page that already uses NIP-07 and make it also work with NIP-46 automatically when the user doesn't have an extension installed.

It adds a small floating button on the side of the window that users can use to create Nostr accuonts or connect to their NIP-46 bunkers.

How to use it

Include <script src="https://cdn.jsdelivr.net/npm/window.nostr.js/dist/window.nostr.min.js"></script> in your HTML and proceed to use window.nostr normally.

Customization

The script supports optional data-* attributes on the <script> tag to personalize the design:

<script src="https://cdn.jsdelivr.net/npm/window.nostr.js/dist/window.nostr.min.js"
  data-accent="green"
  data-position="bottom"
  data-compact-mode
  data-relays='["wss://bucket.coracle.social","wss://relay.nsec.app"]'
  data-app-name='example app
  data-app-image='https://example.com/logo.png'
