A fast and complete ByteBuffer implementation using either ArrayBuffers in the browser or node Buffers under node.js, generated from a single source tree through MetaScript.

If you are looking for ByteBuffer.js 2 (ArrayBuffers only), that's the branch.

What can it do?

• 8, 16, 32 and 64 bit signed and unsigned integers
• 32 and 64 bit floats
• Big and little endianness
• Varints as used in protobuf (32 and 64 bit, zig-zag)
• Base64, binary, debug, hex and utf8 encodings
• Handy string and debugging utilities
• Relative and absolute zero-copy operations wherever possible
• Transparent resizing when using unknown-length data
• Chaining of all operations that do not return a specific value
• Slicing, appending, prepending, reversing, flip, mark, reset, etc.

More

• CommonJS, AMD and shim compatible
• Also available via npm
• Compiled through Closure Compiler using ADVANCED_OPTIMIZATIONS (fully annotated, includes externs and source map)
• Fully documented using jsdoc3
• Well tested through test.js
• Zero production dependencies (Long.js is optional)

Usage

Node.js

• Install: npm install bytebuffer

var ByteBuffer = require("bytebuffer");
var bb = new ByteBuffer();
bb.writeIString("Hello world!").flip();
console.log(bb.readIString()+" from ByteBuffer.js");

Browser

Optionally depends on Long.js for long (int64) support. If you do not require long support, you can skip the Long.js include.

<script src="Long.min.js"></script>
<script src="ByteBufferAB.min.js"></script>

var ByteBuffer = dcodeIO.ByteBuffer;
var bb = new ByteBuffer();
bb.writeIString("Hello world!").flip();
alert(bb.readIString()+" from ByteBuffer.js");

AMD

Optionally depends on Long.js for long (int64) support. If you do not require long support, you can skip the Long.js config. Require.js example:

require.config({
    "paths": {
        "Long": "/path/to/Long.js"
        "ByteBuffer": "/path/to/ByteBufferAB.js"
    }
});
require(["ByteBuffer"], function(ByteBuffer) {
    var bb = new ByteBuffer();
    bb.writeIString("Hello world!").flip();
    alert(bb.readIString()+" from ByteBuffer.js");
});
