Nibbit
JavaScript NBT encoder and decoder
Overview
Nibbit is an easy to use encoder and decoder for the NBT serialisation format, created for and popularised by the game "Minecraft". It'll decode uncompressed NBT data only - decompression is your job.
Features
- Accurate encoding and decoding of most NBT tag types (see below for details)
- Convenient AST generator functions
- Asynchronous and streaming parser (thanks to node-binary)
Bugs and Limitations
- Can't represent integers above 2^53 accurately due to JavaScript's numeric
type being
double
all the time. - Can't encode arbitrary objects for the same reason. Not enough information is available about the numbers being encoded. All encoding has to be done on a specially constructed AST.

Example Usage
var fs = require("fs"),
zlib = require("zlib"),
nibbit = require("nibbit");
// decoding
fs.readFile("./data/test.nbt", function(err, compressed) {
zlib.gunzip(compressed, function(err, uncompressed) {
nbt.decode(data, function(err, decoded) {
console.log(decoded);
});
});
});
// encoding and manual AST construction
var ast = nbt.compound([
nbt.string("Bananrama", "name"),
], "hello world");
nibbit.encode(ast, function(err, uncompressed) {
console.log(uncompressed);
});
