bufferput

BufferPut

Pack multibyte binary values into buffers with specific endiannesses. Based on the original Put by https://github.com/substack/node-put ...this version is intended to be a little more conventional in structure and faster to instantiate and easier for a VM to optimize. Instantiation of this version is more that 500x faster than the original as measured on nodejs 0.10.12.

Installation

To install with npm:

npm install bufferput

To run the tests with expresso:

expresso

Examples

buf.js

Build a buffer

#!/usr/bin/env node

var BufferPut = require('bufferput');
var buf = (new BufferPut())
    .word16be(1337)
    .word8(1)
    .pad(5)
    .put(new Buffer('pow', 'ascii'))
    .word32le(9000)
    .buffer()
;
console.log(buf);

Output: <Buffer 05 39 01 00 00 00 00 00 70 6f 77 28 23 00 00>

stream.js

Send a buffer to a writeable stream

#!/usr/bin/env node

var BufferPut = require('bufferput');
(new BufferPut())
    .word16be(24930)
    .word32le(1717920867)
    .word8(103)
    .write(process.stdout)
;

Output: abcdefg
