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.
npm install b4a
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])

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

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)

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
