ExpressoTS Studio 4.0.0 — first stable release.
Publishes @expressots/studio (local UI + CLI) and @expressots/studio-agent (in-process instrumentation). @expressots/mcp-server stays private in the monorepo for a later release.
Highlights
- Status dashboard, architecture map, request timeline with traces and replay, live logs, error inspector
- Security view: npm audit + OSV advisories with reachability scoring, OWASP API Top 10 runtime posture
- Zero production cost: the adapter loads the agent only in development when installed
- Everything runs locally; nothing is sent off the box
Requires @expressots/core ^4.0.0, @expressots/adapter-express ^4.0.0, Node.js >= 20.19.0.
