Content

The applesauce-content package turns the raw content field of a Nostr event into a structured tree you can render. It handles the messy parts — NIP-19 mentions, hashtags, URLs, lightning invoices, cashu tokens, custom emojis, image galleries, Blossom URIs — so your rendering layer only has to decide how each node type looks.

The package is split into three modules for different event kinds and rendering targets:

• Text — parses kind 1 notes and chat messages into a NAST (Nostr Abstract Syntax Tree)
• Markdown — remark transformers for kind 30023 long-form articles
• React — hooks for rendering parsed trees as JSX

Features

• NAST parser for text notes with a composable transformer pipeline
• Default transformers for links, NIP-19 mentions, hashtags, NIP-30 emojis, image galleries, lightning invoices, cashu tokens, Blossom URIs, and more
• Parsed results are cached on the event, so re-renders are free
• Remark plugins for markdown articles with automatic NIP-21 / NIP-19 linkification
• Works with any renderer — React, plain DOM, server-side, or your own
