• Takes a glob string or an array of glob strings as the first argument.
• Globs are executed in order, so negations should follow positive globs. For example:

fs.src(['!b*.js', '*.js'])

would not exclude any files, but this would

fs.src(['*.js', '!b*.js'])

• Possible options for the second argument:
  • cwd - Specify the working directory the folder is relative to. Default is process.cwd()
  • base - Specify the folder relative to the cwd. Default is where the glob begins. This is used to determine the file names when saving in .dest()
  • buffer - true or false if you want to buffer the file.
    • Default value is true
    • false will make file.contents a paused Stream
  • read - true or false if you want the file to be read or not. Useful for stuff like rming files.
    • Default value is true
    • false will disable writing the file to disk via .dest()
  • since - Date or number if you only want files that have been modified since the time specified.
  • passthrough - true or false if you want a duplex stream which passes items through and emits globbed files.
  • Any glob-related options are documented in glob-stream and node-glob
• Returns a Readable stream by default, or a Duplex stream if the passthrough option is set to true.
• This stream emits matching vinyl File objects

This is just glob-watcher

• Takes a glob string or an array of glob strings as the first argument.
• Possible options for the second argument:
  • Any options are passed to gaze
• Returns an EventEmitter
  • 'changed' event is emitted on each file change
• Optionally calls the callback on each change event

• Takes a folder path as the first argument.
• First argument can also be a function that takes in a file and returns a folder path.
• Possible options for the second argument:
  • cwd - Specify the working directory the folder is relative to. Default is process.cwd()
  • mode - Specify the mode the files should be created with. Default is the mode of the input file (file.stat.mode) or the process mode if the input file has no mode property.
  • dirMode - Specify the mode the directory should be created with. Default is the process mode.
  • overwrite - Specify if existing files with the same path should be overwritten or not. Default is true, to always overwrite existing files
• Returns a Readable/Writable stream.
• On write the stream will save the vinyl File to disk at the folder/cwd specified.
• After writing the file to disk, it will be emitted from the stream so you can keep piping these around.
• The file will be modified after being written to this stream:
  • cwd, base, and path will be overwritten to match the folder
  • stat.mode will be overwritten if you used a mode parameter
  • contents will have it's position reset to the beginning if it is a stream

• Takes a folder path as the first argument.
• First argument can also be a function that takes in a file and returns a folder path.
• Possible options for the second argument:
  • cwd - Specify the working directory the folder is relative to. Default is process.cwd()
  • dirMode - Specify the mode the directory should be created with. Default is the process mode.
• Returns a Readable/Writable stream.
• On write the stream will create a symbolic link (i.e. symlink) on disk at the folder/cwd specified.
• After creating the symbolic link, it will be emitted from the stream so you can keep piping these around.
• The file will be modified after being written to this stream:
  • cwd, base, and path will be overwritten to match the folder
