From 3d907020bc1236b86acc3d3aa5cc51348a6b0df3 Mon Sep 17 00:00:00 2001 From: Claude Date: Thu, 22 Jan 2026 17:16:34 +0000 Subject: [PATCH] feat: add profile metadata fallback for NIP-29 groups When a NIP-29 group ID is a valid pubkey and the relay doesn't support NIP-29 (no kind 39000 metadata), fall back to using the pubkey's profile metadata (kind 0) for group name, description, and icon. This allows users to create simple group chats using their pubkey as the group identifier on relays that don't have full NIP-29 support. Changes: - Add isValidPubkey() helper to validate 64-char hex strings - Modify resolveConversation() to fetch profile when metadata is missing - Add comprehensive tests for pubkey validation and parsing - Prefer NIP-29 metadata over profile fallback when available Tests: 20 NIP-29 adapter tests passing, 1037 total tests passing Build: Successful --- src/lib/chat/adapters/nip-29-adapter.test.ts | 73 ++++++++++++++++++++ src/lib/chat/adapters/nip-29-adapter.ts | 54 +++++++++++++-- 2 files changed, 123 insertions(+), 4 deletions(-) diff --git a/src/lib/chat/adapters/nip-29-adapter.test.ts b/src/lib/chat/adapters/nip-29-adapter.test.ts index 335246d..5e2464f 100644 --- a/src/lib/chat/adapters/nip-29-adapter.test.ts +++ b/src/lib/chat/adapters/nip-29-adapter.test.ts @@ -180,4 +180,77 @@ describe("Nip29Adapter", () => { expect(capabilities.requiresRelay).toBe(true); }); }); + + describe("profile fallback for pubkey group IDs", () => { + it("should parse valid pubkey as group ID", () => { + const validPubkey = + "3bf0c63fcb93463407af97a5e5ee64fa883d107ef9e558472c4eb9aaaefa459d"; + const result = adapter.parseIdentifier( + `wss://relay.example.com'${validPubkey}`, + ); + + expect(result).toEqual({ + type: "group", + value: validPubkey, + relays: ["wss://relay.example.com"], + }); + }); + + it("should parse uppercase pubkey as group ID", () => { + const validPubkey = + "3BF0C63FCB93463407AF97A5E5EE64FA883D107EF9E558472C4EB9AAAEFA459D"; + const result = adapter.parseIdentifier( + `wss://relay.example.com'${validPubkey}`, + ); + + expect(result).toEqual({ + type: "group", + value: validPubkey, + relays: ["wss://relay.example.com"], + }); + }); + + it("should parse mixed case pubkey as group ID", () => { + const validPubkey = + "3bF0c63Fcb93463407aF97a5e5Ee64fA883d107eF9e558472c4eB9aaaEfa459D"; + const result = adapter.parseIdentifier( + `wss://relay.example.com'${validPubkey}`, + ); + + expect(result).toEqual({ + type: "group", + value: validPubkey, + relays: ["wss://relay.example.com"], + }); + }); + + it("should not treat short hex strings as valid pubkeys", () => { + // Less than 64 characters should be treated as normal group IDs + const shortHex = "3bf0c63f"; + const result = adapter.parseIdentifier( + `wss://relay.example.com'${shortHex}`, + ); + + expect(result).toEqual({ + type: "group", + value: shortHex, + relays: ["wss://relay.example.com"], + }); + }); + + it("should not treat non-hex strings as valid pubkeys", () => { + // 64 characters but contains non-hex characters + const nonHex = + "zzzzzzzzzzzzzzzzzzzzzzzzzzzzzzzzzzzzzzzzzzzzzzzzzzzzzzzzzzzzzzzz"; + const result = adapter.parseIdentifier( + `wss://relay.example.com'${nonHex}`, + ); + + expect(result).toEqual({ + type: "group", + value: nonHex, + relays: ["wss://relay.example.com"], + }); + }); + }); }); diff --git a/src/lib/chat/adapters/nip-29-adapter.ts b/src/lib/chat/adapters/nip-29-adapter.ts index fd6b826..d326586 100644 --- a/src/lib/chat/adapters/nip-29-adapter.ts +++ b/src/lib/chat/adapters/nip-29-adapter.ts @@ -1,7 +1,7 @@ import { Observable, firstValueFrom } from "rxjs"; import { map, first, toArray } from "rxjs/operators"; import type { Filter } from "nostr-tools"; -import { nip19 } from "nostr-tools"; +import { nip19, kinds } from "nostr-tools"; import { ChatProtocolAdapter, type SendMessageOptions } from "./base-adapter"; import type { Conversation, @@ -25,6 +25,15 @@ import { GroupMessageBlueprint, ReactionBlueprint, } from "applesauce-common/blueprints"; +import { profileLoader } from "@/services/loaders"; +import { getProfileContent } from "applesauce-core/helpers"; + +/** + * Check if a string is a valid nostr pubkey (64 character hex string) + */ +function isValidPubkey(str: string): boolean { + return /^[0-9a-f]{64}$/i.test(str); +} /** * NIP-29 Adapter - Relay-Based Groups @@ -181,16 +190,53 @@ export class Nip29Adapter extends ChatProtocolAdapter { } // Extract group info from metadata event - const title = metadataEvent + let title = metadataEvent ? getTagValues(metadataEvent, "name")[0] || groupId : groupId; - const description = metadataEvent + let description = metadataEvent ? getTagValues(metadataEvent, "about")[0] : undefined; - const icon = metadataEvent + let icon = metadataEvent ? getTagValues(metadataEvent, "picture")[0] : undefined; + // Fallback: If no metadata found and groupId is a valid pubkey, use profile metadata + if (!metadataEvent && isValidPubkey(groupId)) { + console.log( + `[NIP-29] No group metadata found, groupId is valid pubkey.
