Allocates a new buffer containing the given {str}.
String to store in buffer.
Optional
encoding: stringencoding to use, optional. Default is 'utf8'
Allocates a new buffer of {size} octets.
count of octets to allocate.
Allocates a new buffer containing the given {array} of octets.
The octets to store.
Produces a Buffer backed by the same allocated memory as the given {ArrayBuffer}.
The ArrayBuffer with which to share memory.
Allocates a new buffer containing the given {array} of octets.
The octets to store.
Copies the passed {buffer} data onto a new {Buffer} instance.
The buffer to copy.
This is the number of bytes used to determine the size of pre-allocated, internal Buffer instances used for pooling. This value may be modified.
Allocates a new buffer of {size} octets.
count of octets to allocate.
Optional
fill: string | number | Bufferif specified, buffer will be initialized by calling buf.fill(fill). If parameter is omitted, buffer will be filled with zeros.
Optional
encoding: stringencoding used for call to buf.fill while initalizing
Gives the actual byte length of a string. encoding defaults to 'utf8'. This is not the same as String.prototype.length since that returns the number of characters in a string.
string to test. (TypedArray is also allowed, but it is only available starting ES2017)
Optional
encoding: stringencoding used to evaluate (defaults to 'utf8')
Returns a buffer which is the result of concatenating all the buffers in the list together.
If the list has no items, or if the totalLength is 0, then it returns a zero-length buffer. If the list has exactly one item, then the first item of the list is returned. If the list has more than one item, then a new Buffer is created.
An array of Buffer objects to concatenate
Optional
totalLength: numberTotal length of the buffers when concatenated. If totalLength is not provided, it is read from the buffers in the list. However, this adds an additional loop to the function, so it is faster to provide the length explicitly.
When passed a reference to the .buffer property of a TypedArray instance, the newly created Buffer will share the same allocated memory as the TypedArray. The optional {byteOffset} and {length} arguments specify a memory range within the {arrayBuffer} that will be shared by the Buffer.
The .buffer property of a TypedArray or a new ArrayBuffer()
Optional
byteOffset: numberOptional
length: numberCreates a new Buffer using the passed {data}
data to create a new Buffer
Creates a new Buffer containing the given JavaScript string {str}. If provided, the {encoding} parameter identifies the character encoding. If not provided, {encoding} defaults to 'utf8'.
Optional
encoding: string
Raw data is stored in instances of the Buffer class. A Buffer is similar to an array of integers but corresponds to a raw memory allocation outside the V8 heap. A Buffer cannot be resized. Valid string encodings: 'ascii'|'utf8'|'utf16le'|'ucs2'(alias of 'utf16le')|'base64'|'binary'(deprecated)|'hex'
