Utilities for standardized logging.

• fileScope(filepath, options) Returns a function which will decorate function names with some combination of the source file path, package name, and package version. If the filepath is index.js, it will be replaced by its containing directory. Defaults for what is included are determined by Squeep opinions on package layouts.

  Example:

  // Assuming this file is located at 'project/lib/subdir/code.js'
  // Assuming project/package.json defines 'name' as 'project'
  const { fileScope } = require('@squeep/log-helper');
  const _fileScope = fileScope(__filename, { includeVersion: false });
  
  function example() {
    const _scope = _fileScope('example');
    console.log(_scope); // Will show 'project:subdir/code:example'
  }

  Options:

  • includePackage Package name from package.json.
  • includeVersion Package version from package.json. If this is true, includePackage will also become true.
  • includePath The path to the file, relative to the package.json file.
  • leftTrim How much of the beginning of the path to elide. (e.g. 3 would render foo/bar as /bar)
  • delimiter Placed between fields, defaults to :.
  • prefix A field included before the package name.

  Defaults, based on directory existing in project:

  	src	lib	other
  includePackage	false	true	false
  includeVersion	false	true	false
  includePath	true	true	false
  leftTrim	4	4	0

  If any errors are encountered while trying to determine the path or package metadata, the scope will be prefixed with a '?'.
