@offirmo/practical-logger-interface v1.1.1

This is an internal component of Offirmo’s practical logger.

• declares only TypeScript types/interfaces
• No code, 0 bytes = will do nothing to your bundle size.
• TODO explain the interface pattern

Usage

This is most likely not what you are looking for!

See the actual implementations of those interfaces:

• minimal no-op: @offirmo/practical-logger-minimal-noop
• browser: @offirmo/practical-logger-browser
• node: TODO publish to npm

Interface

A logger will have the following interface:

• setLevel(level: LogLevel): void
• getLevel(): LogLevel
• addCommonDetails(hash: Readonly<{ [k: string]: any }>): void
• Log primitives: (mirroring the log levels)
  • fatal(message?: string, details?: Readonly<{ [k: string]: any }>): void
  • emerg(…) idem
  • alert(…) idem
  • crit(…) idem
  • error(…) idem
  • warning(…), warn(…) idem
  • notice(…) idem
  • info(…) idem
  • verbose(…) idem
  • log(…) idem
  • debug(…) idem
  • trace(…) idem
  • silly(…) idem
• those functions may not do anything:
  • group(groupTitle?: string): void
  • groupCollapsed(groupTitle?: string): void
  • groupEnd(): void
