traverse(options): Promise<Array>

Traverses the filesystem applying process_file to all files under the given directory.

arguments

options:

{
  directory?: string,
  process_file: (filepath: string) => T,
  include_file?: string | RegExp,
  exclude_file?: string | RegExp,
  include_dir?: string | RegExp,
  exclude_dir?: string | RegExp,
  fs?: typeof fs
}

• directory?: string - The directory from which to recursively process files. Defaults to the current working directory of the process.
• process_file: (filepath: string) => T - A function to be called on each file traversed; the return values become members of the result array.
• include_file: string | RegExp - An optional regex filter that is applied to discovered files. Only files that match are processed - unless they match the exclude_file filter. Defaults to all files.
• exclude_file: string | RegExp - An optional regex filter that is applied to discovered files. Only files that do not match are processed. Defaults to no files.
• include_dir: string | RegExp - An optional regex filter that is applied to discovered directories. If a directory does not match it will not be entered and the files inside will not be processed. Defaults to all directories.
• exclude_dir: string | RegExp - An optional regex filter that is applied to discovered directories. If a directory matches it will not be entered and the files inside will not be processed. Defaults to no directories.
• fs: FS - An optional fs module, such as memfs. Defaults to the NodeJS fs module.

return

• Promise<Array<T>> - A promise that resolves once all of the process_file functions return, and resolves to an array of the return values of process_file. The order of the array is not guaranteed.
