Buffer for Array

Buffer for Array (B4A) provides a set of functions for bridging the gap between the Node.js Buffer class and the Uint8Array class. A browser compatibility layer is also included, making it possible to use B4A in both Node.js and browsers without having to worry about whether you're dealing with buffers or typed arrays.

Installation

npm install b4a

API

b4a.isBuffer(value)

See https://nodejs.org/api/buffer.html#static-method-bufferisbufferobj

This will also return true when passed a Uint8Array.

b4a.isEncoding(encoding)

See https://nodejs.org/api/buffer.html#static-method-bufferisencodingencoding

b4a.alloc(size[, fill[, encoding]])

See https://nodejs.org/api/buffer.html#static-method-bufferallocsize-fill-encoding

b4a.allocUnsafe(size)

See https://nodejs.org/api/buffer.html#static-method-bufferallocunsafesize

b4a.allocUnsafeSlow(size)

See https://nodejs.org/api/buffer.html#static-method-bufferallocunsafeslowsize

b4a.byteLength(string)

See https://nodejs.org/api/buffer.html#static-method-bufferbytelengthstring-encoding

b4a.compare(buf1, buf2)

See https://nodejs.org/api/buffer.html#static-method-buffercomparebuf1-buf2

b4a.concat(buffers[, totalLength])

See https://nodejs.org/api/buffer.html#static-method-bufferconcatlist-totallength

b4a.copy(source, target[, targetStart[, sourceStart[, sourceEnd]]])

See https://nodejs.org/api/buffer.html#bufcopytarget-targetstart-sourcestart-sourceend

b4a.equals(buf1, buf2)

See https://nodejs.org/api/buffer.html#bufequalsotherbuffer

b4a.fill(buffer, value[, offset[, end]][, encoding])

See https://nodejs.org/api/buffer.html#buffillvalue-offset-end-encoding

b4a.from(array)

See https://nodejs.org/api/buffer.html#static-method-bufferfromarray

b4a.from(arrayBuffer[, byteOffset[, length]])

See https://nodejs.org/api/buffer.html#static-method-bufferfromarraybuffer-byteoffset-length

b4a.from(buffer)

See https://nodejs.org/api/buffer.html#static-method-bufferfrombuffer

b4a.from(string[, encoding])

See https://nodejs.org/api/buffer.html#static-method-bufferfromstring-encoding

b4a.includes(buffer, value[, byteOffset][, encoding])

See https://nodejs.org/api/buffer.html#bufincludesvalue-byteoffset-encoding

b4a.indexOf(buffer, value[, byteOffset][, encoding])

See https://nodejs.org/api/buffer.html#bufindexofvalue-byteoffset-encoding

b4a.lastIndexOf(buffer, value[, byteOffset][, encoding])

See https://nodejs.org/api/buffer.html#buflastindexofvalue-byteoffset-encoding

b4a.swap16(buffer)

See https://nodejs.org/api/buffer.html#bufswap16

b4a.swap32(buffer)

See https://nodejs.org/api/buffer.html#bufswap32

b4a.swap64(buffer)

See https://nodejs.org/api/buffer.html#bufswap64

b4a.toBuffer(buffer)

Convert a buffer to its canonical representation. In Node.js, the canonical representation is a Buffer. In the browser, the canonical representation is a Uint8Array.

b4a.toString(buffer, [encoding[, start[, end]]])

See https://nodejs.org/api/buffer.html#buftostringencoding-start-end

b4a.write(buffer, string[, offset[, length]][, encoding])

See https://nodejs.org/api/buffer.html#bufwritestring-offset-length-encoding

b4a.writeDoubleLE(buffer, value[, offset])

See https://nodejs.org/api/buffer.html#bufwritedoublelevalue-offset

b4a.writeFloatLE(buffer, value[, offset])

See https://nodejs.org/api/buffer.html#bufwritefloatlevalue-offset

b4a.writeUInt32LE(buffer, value[, offset])

https://nodejs.org/api/buffer.html#bufwriteuint32levalue-offset

b4a.writeInt32LE(buffer, value[, offset])

See https://nodejs.org/api/buffer.html#bufwriteint32levalue-offset

b4a.readDoubleLE(buffer[, offset])

See https://nodejs.org/api/buffer.html#bufreaddoubleleoffset

b4a.readFloatLE(buffer[, offset])

See https://nodejs.org/api/buffer.html#bufreadfloatleoffset

b4a.readUInt32LE(buffer[, offset])

See https://nodejs.org/api/buffer.html#bufreaduint32leoffset

b4a.readInt32LE(buffer[, offset])

See https://nodejs.org/api/buffer.html#bufreadint32leoffset
