bufferish

bufferish

This module provides some compatible methods of Node.js's Buffer API which work with Uint8Array and Array as well as Buffer instance. It's light-weight and just 5KB when minified without Buffer shim.

alloc(size)

See Buffer.alloc().

Bufferish.Array.alloc(size)

It creates a new Array instance of size elements.

Bufferish.Buffer.alloc(size)

It creates a new Buffer instance of size bytes. It's available only when Buffer class available.

Bufferish.Uint8Array.alloc(size)

It creates a new Uint8Array instance of size bytes. It's available only when Uint8Array class available.

Bufferish.alloc(size)

It creates a new instance of one of Buffer, Uint8Array or Array, depending on the environment.

Bufferish.alloc.call(ref, size)

It creates the same type instance of ref which is one of Buffer, Uint8Array or Array instances. It may cost less when a native copy methods is available.

from(src)

See Buffer.from(). src is an Array-like instance such as Buffer, Uint8Array or Array. String is also allowed.

Bufferish.Array.from(src)

It creates a new Array instance copied from src.

Bufferish.Buffer.from(src)

It creates a new Buffer instance copied from src.

Bufferish.Uint8Array.from(src)

It creates a new Uint8Array instance copied from src.

Bufferish.from(src)

It creates a copied instance of one of Buffer, Uint8Array or Array, depending on the environment.

concat(list)

See Buffer.concat(). list is an Array which contains an Array-like instances such Buffer, Uint8Array or Array.

Bufferish.Array.concat(list)

It creates a new Array instance concatenated.

Bufferish.Buffer.concat(list)

It creates a new Buffer instance concatenated.

Bufferish.Uint8Array.concat(list)

It creates a new Uint8Array instance concatenated.

Bufferish.concat(list)

It creates a concatenated instance of one of Buffer, Uint8Array or Array, depending on the environment.

Bufferish.isXXX()

Bufferish.isArray(array)

It returns true if array is an Array instance. See Array.isArray().

Bufferish.isArrayBuffer(arraybuffer)

It returns true if arraybuffer is an ArrayBuffer instance.

Bufferish.isBuffer(buffer)

It returns true if buffer is a Buffer instance. See Buffer.isBuffer().

Bufferish.isView(typedarray)

It returns true if typedarray is Uint8Array or other TypedArray instance. See ArrayBuffer.isView().

Bufferish.prototype.XXX.call()

Those methods must be called with call() to perform the trick.

src is an Array-like instance such as Buffer, Uint8Array or Array.

Bufferish.prototype.copy.call(src, target, targetStart, start, end)

It copies data from a region of src to a region in target. See Buffer.prototype.copy().

Bufferish.prototype.slice.call(src, start, end)

It returns a new instance from a region of src. See Buffer.prototype.slice().

Bufferish.prototype.toString.call(src, encoding, start, end)

It returns a String from a region of src. Please note that encoding may not be supported and just ignored. See Buffer.prototype.toString().

Bufferish.prototype.write.call(buf, string, offset)

It writes String to buf at the offset. See Buffer.prototype.write().

Other methods

Any other methods which are not described above are not supported with the module. Please consult with Buffer shim instead.

Installation

npm install bufferish --save
