Major type safety improvements throughout the codebase:
- Updated DEFAULT_CONFIG version to 4.2
- Replaced 'any' with proper types in systemd.ts:
* displaySingleUpsStatus now uses IUpsConfig and NupstSnmp types
* Fixed legacy config handling to use proper IUpsConfig format
* Removed inline 'any' type annotations
- Replaced 'any' with proper types in daemon.ts:
* emergencyUps now properly typed as { ups: IUpsConfig, status: ISnmpUpsStatus }
* Exported IUpsStatus interface for reuse
* Added ISnmpUpsStatus import to disambiguate from daemon's IUpsStatus
- Replaced 'any' with Record<string, unknown> in migration system:
* Updated BaseMigration abstract class signatures
* Updated MigrationRunner.run() signature
* Updated migration-v4.0-to-v4.1.ts to use proper types
* Migrations use Record<string, unknown> because they deal with
unknown config schemas that are being upgraded
Benefits:
- TypeScript now catches type errors at compile time
- Would have caught the ups.thresholds bug earlier
- Better IDE autocomplete and type checking
- More maintainable and self-documenting code
- Add proper ES6 imports at top of file for theme, symbols, colors
- Remove all require() calls that were causing 'require is not defined' errors
- Daemon now starts properly with modernized logging intact
- Modernize periodic status update with logger.logTable() and color-coded battery/runtime
- Modernize configuration loaded display with tables for UPS devices and groups
- Enhance power status change notifications with better colors and timestamps
- Modernize shutdown monitoring with real-time table display of UPS status
- Add color-coded CRITICAL indicators for emergency conditions
- Improve visual hierarchy with appropriate box styles (info, warning, error, success)
- Ensure consistent theming across all daemon log output
- Add process.stdin.destroy() after rl.close() in all interactive commands
to properly release stdin and allow process to exit cleanly
- Replace raw console.log with logger methods throughout CLI handlers
- Convert manual box drawing to logger.logBox() in daemon.ts
- Standardize menu formatting with logger.info() and logger.dim()
- Improve migration output to only show when migrations actually run
Fixes issue where process would not exit after "Setup complete!" message
due to stdin keeping the event loop alive.
- Create abstract BaseMigration class with order, shouldRun(), migrate()
- Add MigrationRunner to execute migrations in order
- Add Migration v1→v2 (snmp → upsDevices)
- Add Migration v3→v4 (upsList → upsDevices)
- Update INupstConfig with version field
- Update loadConfig() to run migrations automatically
- Update saveConfig() to ensure version field and remove legacy fields
- Update Docker test scripts to use real UPS data from .nogit/env.json
- Remove colors.bright (not available in @std/fmt/colors)
Config migrations allow users to jump versions (e.g., v1→v4) with all
intermediate migrations running automatically. Version field tracks
config format for future migrations.
Major improvements:
- Created color theme system (ts/colors.ts) with ANSI colors
- Enhanced logger with colors, table formatting, and styled boxes
- Fixed daemon exit bug - now stays running when no UPS configured
- Added config hot-reload with file watcher for live updates
- Beautified CLI help output with color-coded commands
- Added showcase test demonstrating all output features
- Fixed ANSI code handling for perfect table/box alignment
Features:
- Color-coded messages (success=green, error=red, warning=yellow, info=cyan)
- Status symbols (●○◐◯ for running/stopped/starting/unknown)
- Battery level colors (green>60%, yellow 30-60%, red<30%)
- Table formatting with auto-sizing and column alignment
- Styled boxes (success, error, warning, info styles)
- Hot-reload: daemon watches config file and reloads automatically
- Idle mode: daemon stays alive when no devices, checks periodically
Daemon improvements:
- No longer exits when no UPS devices configured
- Enters idle monitoring loop waiting for config
- File watcher detects config changes in real-time
- Auto-reloads and starts monitoring when devices added
- Logs warnings instead of errors for missing devices
Technical fixes:
- Strip ANSI codes when calculating text width for alignment
- Use visible length for padding calculations in tables and boxes
- Properly handle colored text in table cells and box lines
Breaking changes: None (backward compatible)
- 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
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
Files modified:
- ts/cli.ts: config.snmp/thresholds null checks, unused error variable fixes
- ts/cli/group-handler.ts: 4 error.message fixes + 2 parameter type annotations
- ts/cli/service-handler.ts: 3 error.message fixes
- ts/cli/ups-handler.ts: 5 error.message fixes + config checks + TUpsModel import
- ts/daemon.ts: 8 error.message fixes + IUpsStatus lastStatusChange fix + updateAvailable type
- ts/nupst.ts: 1 error.message fix
- ts/systemd.ts: 5 error.message fixes + parameter type annotation
All tests passing (3/3 SNMP tests + 10/10 logger tests)
Type check: ✓ No errors
- Created deno.json configuration
