API

src(globs[, opt])

• Takes a glob string or an array of glob strings as the first argument.
• 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()
  • Any glob-related options are documented in glob-stream and node-glob
• Returns a Readable/Writable stream.
• On write the stream will simply pass items through.
• This stream emits matching vinyl File objects

watch(globs[, opt, cb])

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

dest(folder[, opt])

• 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)
• 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
