vinyl-fs

Information

Usage

var map = require('map-stream');
var fs = require('vinyl-fs');

var log = function(file, cb) {
  console.log(file.path);
  cb(null, file);
};

fs.src(['./js/**/*.js', '!./js/vendor/*.js'])
  .pipe(map(log))
  .pipe(fs.dest('./output'));

API

src(globs[, opt])

• 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. This is used to determine the file names when saving in .dest().

    • Default is where the glob begins if any.
    • Default is process.cwd() if there is no glob.

  • 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.

    • Default is false.

  • sourcemaps - true or false if you want files to have sourcemaps enabled.

    • Default is false.

  • followSymlinks - true if you want to recursively resolve symlinks to their targets; set to false to preserve them as symlinks.

    • Default is true.
    • false will make file.symlink equal the original symlink's target path.

  • 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.

Note: UTF-8 BOM will be stripped from all UTF-8 files read with .src.

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().

  • base - Specify the folder relative to the cwd. This is used to determine the file names when saving in .dest().

    • Default is the cwd resolves to the folder path.
    • Can also be a function that takes in a file and returns a folder path.

  • mode - Specify the mode the files should be created with.

    • Default is the mode of the input file (file.stat.mode) if any.
    • Default is 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.

• If the file has a symlink attribute specifying a target path, then a symlink will be created.

• 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.

symlink(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().

  • base - Specify the folder relative to the cwd. This is used to determine the file names when saving in .dest().

    • Default is the cwd resolves to the folder path.
    • Can also be a function that takes in a file and returns a folder path.

  • 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.
