Virtual file format.

What is Vinyl?

Vinyl is a very simple metadata object that describes a file. When you think of a file, two attributes come to mind: path and contents. These are the main attributes on a Vinyl object. A file does not necessarily represent something on your computer’s file system. You have files on S3, FTP, Dropbox, Box, CloudThingly.io and other services. Vinyl can be used to describe files from all of these sources.

What is a Vinyl Adapter?

While Vinyl provides a clean way to describe a file, we also need a way to access these files. Each file source needs what I call a "Vinyl adapter". A Vinyl adapter simply exposes a src(globs) and a dest(folder) method. Each return a stream. The src stream produces Vinyl objects, and the dest stream consumes Vinyl objects. Vinyl adapters can expose extra methods that might be specific to their input/output medium, such as the symlink method vinyl-fs provides.

Usage

var Vinyl = require('vinyl');

var jsFile = new Vinyl({
  cwd: '/',
  base: '/test/',
  path: '/test/file.js',
  contents: Buffer.from('var x = 123')
});

API

new Vinyl([options])

The constructor is used to create a new instance of Vinyl. Each instance represents a separate file, directory or symlink.

All internally managed paths (cwd, base, path, history) are normalized and have trailing separators removed. See Normalization and concatenation for more information.

Options may be passed upon instantiation to create a file with specific properties.

options

Options are not mutated by the constructor.

options.cwd

The current working directory of the file.

Type: String

Default: process.cwd()

options.base

Used for calculating the relative property. This is typically where a glob starts.

Type: String

Default: options.cwd

options.path

The full path to the file.

Type: String

Default: undefined

options.history

Stores the path history. If options.path and options.history are both passed, options.path is appended to options.history. All options.history paths are normalized by the file.path setter.

Type: Array

Default: [] (or [options.path] if options.path is passed)

options.stat

The result of an fs.stat call. This is how you mark the file as a directory or symbolic link. See isDirectory(), isSymbolic() and fs.Stats for more information.

Type: fs.Stats

Default: undefined

options.contents

The contents of the file. If options.contents is a ReadableStream, it is wrapped in a cloneable-readable stream.

Type: ReadableStream, Buffer, or null

Default: null

options.{custom}

Any other option properties will be directly assigned to the new Vinyl object.

var Vinyl = require('vinyl');

var file = new Vinyl({ foo: 'bar' });
file.foo === 'bar'; // true

Instance methods

Each Vinyl object will have instance methods. Every method will be available but may return differently based on what properties were set upon instantiation or modified since.

file.isBuffer()

Returns true if the file contents are a Buffer, otherwise false.

file.isStream()

Returns true if the file contents are a Stream, otherwise false.

file.isNull()

Returns true if the file contents are null, otherwise false.

file.isDirectory()

Returns true if the file represents a directory, otherwise false.

A file is considered a directory when:

  • file.isNull() is true
  • file.stat is an object
  • file.stat.isDirectory() returns true

When constructing a Vinyl object, pass in a valid fs.Stats object via options.stat. If you are mocking the fs.Stats object, you may need to stub the isDirectory() method.

file.isSymbolic()

Returns true if the file represents a symbolic link, otherwise false.

A file is considered symbolic when:

  • file.isNull() is true
  • file.stat is an object
  • file.stat.isSymbolicLink() returns true

When constructing a Vinyl object, pass in a valid fs.Stats object via options.stat. If you are mocking the fs.Stats object, you may need to stub the isSymbolicLink() method.

file.clone([options])

Returns a new Vinyl object with all attributes cloned.

By default custom attributes are cloned deeply.

If options or options.deep is false, custom attributes will not be cloned deeply.

If file.contents is a Buffer and options.contents is false, the Buffer reference will be reused instead of copied.

file.inspect()

Returns a formatted-string interpretation of the Vinyl object. Automatically called by node's console.log.

Instance properties

Each Vinyl object will have instance properties. Some may be unavailable based on what properties were set upon instantiation or modified since.

file.contents

Gets and sets the contents of the file. If set to a ReadableStream, it is wrapped in a cloneable-readable stream.

Throws when set to any value other than a ReadableStream, a Buffer or null.

Type: ReadableStream, Buffer, or null

file.cwd

Gets and sets current working directory. Will always be normalized and have trailing separators removed.

Throws when set to any value other than non-empty strings.

Type: String

file.base

Gets and sets base directory. Used for relative pathing (typically where a glob starts). When null or undefined, it simply proxies the file.cwd property. Will always be normalized and have trailing separators removed.

Throws when set to any value other than non-empty strings or null/undefined.

Type: String

file.path

Gets and sets the absolute pathname string or undefined. Setting to a different value appends the new path to file.history. If set to the same value as the current path, it is ignored. All new values are normalized and have trailing separators removed.

Throws when set to any value other than a string.

Type: String

file.history

Array of file.path values the Vinyl object has had, from file.history[0] (original) through file.history[file.history.length - 1] (current). file.history and its elements should normally be treated as read-only and only altered indirectly by setting file.path.

Type: Array

file.relative

Gets the result of path.relative(file.base, file.path).

Throws when set or when file.path is not set.

Type: String

Example:

var file = new File({
  cwd: '/',
  base: '/test/',
  path: '/test/file.js'
});

console.log(file.relative); // file.js

file.dirname

Gets and sets the dirname of file.path. Will always be normalized and have trailing separators removed.

Throws when file.path is not set.

Type: String

Example:

var file = new File({
  cwd: '/',
  base: '/test/',
  path: '/test/file.js'
});

console.log(file.dirname); // /test

file.dirname = '/specs';

console.log(file.dirname); // /specs
console.log(file.path); // /specs/file.js

file.basename

Gets and sets the basename of file.path.

Throws when file.path is not set.

Type: String

Example:

var file = new File({
  cwd: '/',
  base: '/test/',
  path: '/test/file.js'
});

console.log(file.basename); // file.js

file.basename = 'file.txt';

console.log(file.basename); // file.txt
console.log(file.path); // /test/file.txt

file.stem

Gets and sets stem (filename without suffix) of file.path.

Throws when file.path is not set.

Type: String

Example:

var file = new File({
  cwd: '/',
  base: '/test/',
  path: '/test/file.js'
});

console.log(file.stem); // file

file.stem = 'foo';

console.log(file.stem); // foo
console.log(file.path); // /test/foo.js

file.extname

Gets and sets extname of file.path.

Throws when file.path is not set.

Type: String

Example:

var file = new File({
  cwd: '/',
  base: '/test/',
  path: '/test/file.js'
});

console.log(file.extname); // .js

file.extname = '.txt';

console.log(file.extname); // .txt
console.log(file.path); // /test/file.txt

file.symlink

Gets and sets the path where the file points to if it's a symbolic link. Will always be normalized and have trailing separators removed.

Throws when set to any value other than a string.

Type: String

Vinyl.isVinyl(file)

Static method used for checking if an object is a Vinyl file. Use this method instead of instanceof.

Takes an object and returns true if it is a Vinyl file, otherwise returns false.

Note: This method uses an internal flag that some older versions of Vinyl didn't expose.

Example:

var Vinyl = require('vinyl');

var file = new Vinyl();
var notAFile = {};

Vinyl.isVinyl(file); // true
Vinyl.isVinyl(notAFile); // false

Vinyl.isCustomProp(property)

Static method used by Vinyl when setting values inside the constructor or when copying properties in file.clone().

Takes a string property and returns true if the property is not used internally, otherwise returns false.

This method is useful for inheritting from the Vinyl constructor. Read more in Extending Vinyl.

Example:

var Vinyl = require('vinyl');

Vinyl.isCustomProp('sourceMap'); // true
Vinyl.isCustomProp('path'); // false -> internal getter/setter

Normalization and concatenation

Since all properties are normalized in their setters, you can just concatenate with /, and normalization takes care of it properly on all platforms.

Example:

var file = new File();
file.path = '/' + 'test' + '/' + 'foo.bar';

console.log(file.path);
// posix => /test/foo.bar
// win32 => \\test\\foo.bar

But never concatenate with \, since that is a valid filename character on posix system.

Extending Vinyl

When extending Vinyl into your own class with extra features, you need to think about a few things.

When you have your own properties that are managed internally, you need to extend the static isCustomProp method to return false when one of these properties is queried.

var Vinyl = require('vinyl');

var builtInProps = ['foo', '_foo'];

class SuperFile extends Vinyl {
  constructor(options) {
    super(options);
    this._foo = 'example internal read-only value';
  }

  get foo() {
    return this._foo;
  }

  static isCustomProp(name) {
    return super.isCustomProp(name) && builtInProps.indexOf(name) === -1;
  }
}

// `foo` won't be assigned to the object below
new SuperFile({ foo: "something" });

This makes properties foo and _foo skipped when passed in options to constructor(options) so they don't get assigned to the new object and override your custom implementation. They also won't be copied when cloning. Note: The _foo and foo properties will still exist on the created/cloned object because you are assigning _foo in the constructor and foo is defined on the prototype.

Same goes for clone(). If you have your own internal stuff that needs special handling during cloning, you should extend it to do so.
