NATS Explorer

Browse and inspect NATS JetStream streams and subjects from VSCode. Inspired by Qaze and pg-explorer-vsce.

Features

• Connection manager — add, edit, delete NATS connections (user/pass, token, TLS), with color-coding and tags; credentials kept in VSCode Secret Storage.
• Tree browser — Connection → Streams → Subjects in the sidebar.
• Latest-N message table — view the newest messages of a stream or subject, newest-first.
• Detail sidebar — inspect message headers and syntax-highlighted JSON payloads.
• Subject filter — narrow a stream view by contains or regex (case-sensitive variants).
• Stream / subject info — read-only config and state for streams, message counts for subjects.

See FEATURES.md for the full capability list and the development backlog.
