nobel is a family of small nostr libraries for plain HTML, each a lightweight take on something bigger and each named for an element. Every library is one dependency-free script under 5kb, and they work together through DOM events, the way the fixi project libraries do.

Plain <script> tags work in any order. Tick what you need above (what it needs is added) for one file from jsDelivr, in an order that also works with async:
Or download the files from the table, or take all of them in one file: nobel.js, nobel.min.js (40.8kb, 15.1kb brotli).
Add ?relay=wss://... to each: 📰 feed, ✉️ private messages, 👻 presence, typing, cursors, 🪞 profiles, 🔴 note embeds.
