- Remove async from functions that don't use await
- Change return types from Promise<void> to void for synchronous functions
- Fixes all 8 require-await lint warnings
- Reduces total lint warnings from 63 to 55
- Clean old binaries from dist/binaries before each build
- Automatically delete old releases, keeping only the last 3
- Prevents accumulation of stale binaries and release storage bloat
Enhanced install.sh to properly handle updates and migrations:
**Update Detection & Service Management:**
- Detect old Node.js-based installations (v3.x) via package.json/node_modules
- Stop running service before updating binary
- Restart service after successful update if it was running
- Preserve /etc/nupst/config.json during updates
**Migration from v3.x to v4.0:**
- Clean up old Node.js installation files:
- node_modules/, vendor/, dist_ts/ directories
- package.json, package-lock.json, pnpm-lock.yaml
- tsconfig.json, setup.sh, bin/ directory
- Inform user about migration with helpful feedback
- Link to migration guide documentation
**User Experience Improvements:**
- Show different messages for new installs vs updates
- Inform about v3.x → v4.0 migration when detected
- Display migration guide link for old installations
- Show service restart status
- Provide context-aware next steps based on config presence
**Safety Features:**
- Ask for confirmation before replacing existing installation (interactive mode)
- Preserve user configuration in /etc/nupst/
- Handle service state properly (stop → update → restart)
- Graceful cleanup with error suppression (|| true)
This ensures seamless updates from any version (including v3.x Node.js installs)
to v4.0+ Deno-based binaries without manual intervention or data loss.
Comprehensive type safety improvements across all CLI handlers and daemon:
**Error handling type fixes:**
- Add 'error instanceof Error' checks before accessing error.message throughout
- Fix all error/retryError/stdError/upsError type assertions
- Replace direct error.message with proper type guards
**Switch case improvements:**
- Wrap case block declarations in braces to satisfy deno-lint
- Fix no-case-declarations warnings in CLI command handlers
**Null/undefined safety:**
- Add checks for config.snmp and config.thresholds before access
- Fix IUpsStatus lastStatusChange to handle undefined with default value
- Add proper null checks in legacy configuration paths
**Type annotations:**
- Add explicit type annotations to lambda parameters (groupId, updateAvailable, etc.)
- Add TUpsModel type cast for 'cyberpower' default
- Import and use INupstConfig type where needed
**Parameter type fixes:**
- Fix implicit 'any' type errors in array callbacks
- Add type annotations to filter/find/map parameters

Major Changes:
- Reorganized commands into logical groups (service, ups, group)
- Added new subcommand structure:
- nupst service <enable|disable|start|stop|restart|status|logs|start-daemon>
- nupst ups <add|edit|remove|list|test>
- nupst group <add|edit|remove|list>
- nupst config [show]
- Added --version/-v flag support
- Added restart subcommand for service
- Added command aliases (ls, rm)
- Renamed delete() to remove() in handlers
- Maintained backward compatibility with deprecation warnings
- Updated all help messages to reflect new structure
- Added showVersion(), showServiceHelp(), showUpsHelp() methods
- Fixed readline imports to use node:readline
Breaking Changes:
- Old command format (e.g. 'nupst add') is deprecated
- Users should migrate to new format (e.g. 'nupst ups add')
- Backward compatibility maintained with warnings for now
- Created scripts/compile-all.sh for all 5 platforms
- Successfully compiled binaries for:
- Linux x64 (345MB)
- Linux ARM64 (340MB)
