Remove axios from the realtime server dependencies to avoid header injection risk,
switch Docker builds to npm ci, and bump the realtime image version to 1.0.15.
- Kill PTY and notify client after 30 min of inactivity (IDLE_TIMEOUT_MS)
- Buffer client messages during async auth/IP fetch to prevent race-condition
message loss on fast reconnects
- Replay last sent command after transient reconnect so PTY respawns without
user interaction
- Preserve scrollback on disconnect/reconnect; write visible timestamp markers
instead of wiping term state
- Handle idle-timeout sentinel on client with user-facing error message
Proxies (Cloudflare, nginx) drop idle WebSocket connections before the
application notices, leaving clients typing into dead sockets.
- Add server-side ping/pong heartbeat (30s) in terminal-server.js;
terminate unresponsive clients instead of letting connections go stale
- Move client keepAlive interval start to the connect event so it
restarts correctly after reconnects
- Remove hidden-tab keepalive short-circuit — server pings now own
liveness; suppressing client pings while hidden masked proxy drops
- Fix clearAllTimers to use clearTimeout for one-shot timers
- On visibility resume, probe with a 5s timeout instead of the default
35s so half-open sockets are detected quickly
- Bump coolify-realtime to 1.0.14 across all compose files
