From d33643e0683dfac4037c0b61d4aa823782f582e7 Mon Sep 17 00:00:00 2001 From: Adam Soltys Date: Sun, 2 Aug 2026 17:51:37 -0700 Subject: Recipient search: usernames and npubs, in chat and the Send form MIME-Version: 1.0 Content-Type: text/plain; charset=UTF-8 Content-Transfer-Encoding: 8bit A shared engine (src/recipient-search.js) merges three ranked sources: an exact npub/hex paste, coinos usernames from the registrar's new /search prefix endpoint, and NIP-50 kind-0 full-text search on relay.nostr.band — the approach the major web clients take, since ordinary relays don't index profiles. Results dedupe by pubkey, fill avatars in one batched kind-0 fetch, and cache per query so narrowing never re-hits the network. Input is debounced 300ms and gated by a searchable() heuristic so addresses, invoices, and keys never trigger a search. Chat's New message panel narrows as you type and opens the thread on pick; the Send form shows the same candidates under the destination input and picking one runs the normal paste path (payment address → BIP-353, npub → zap).
