APIs

It exports a single object as default export: logger. logger has the following properties:

• Some useful colors.
  • red
  • yellow
  • green
  • bold
  • dim
• Formatters. These functions all have the signature (msg: unknown) => string. Note that their implementations are not guaranteed. You should only care about their semantics.
  • path: formats a file path.
  • url: formats a URL.
  • name: formats an identifier.
  • code: formats a code snippet.
  • subdue: subdues the text.
  • num: formats a number.
• The interpolate function. It is a template literal tag. The syntax can be found below.
• Logging functions. All logging functions can both be used as normal functions (similar to the console.log family, but only accepts one parameter) or template literal tags.
  • info: prints information.
  • warn: prints a warning that should be paid attention to.
  • error: prints an error (not necessarily halting the program) that signals significant problems.
  • success: prints a success message.
• The report function. It takes a ReportingSeverity value (ignore, log, warn, throw) and reports a message according to the severity.
