Prismarine-NBT

Prismarine-NBT is a JavaScript parser and serializer for NBT archives, for use with Node.js.

Usage

var fs = require('fs'),
    nbt = require('prismarine-nbt');

fs.readFile('bigtest.nbt', function(error, data) {
    if (error) throw error;

    nbt.parse(data, function(error, data) {
        console.log(data.value.stringTest.value);
        console.log(data.value['nested compound test'].value);
    });
});

If the data is gzipped, it is automatically decompressed first.

API

writeUncompressed(value,[isLittleEndian])

Returns a buffer with a serialized nbt value. If isLittleEndian is passed and is true, write little endian nbt (mcpe).

parseUncompressed(data,[isLittleEndian])

Takes a buffer data and returns a parsed nbt value. If isLittleEndian is passed and is true, read little endian nbt (mcpe).

parse(data,[isLittleEndian], callback)

Takes an optionally compressed data and provide a parsed nbt value in the callback(err,value). If isLittleEndian is passed and is true, read little endian nbt (mcpe).

simplify(nbt)

Returns a simplified nbt representation : keep only the value to remove one level. This loses the types so you cannot use the resulting representation to write it back to nbt.

proto

Provide the protodef instance used to parse and serialize nbt.

protoLE

Provide the protodef instance used to parse and serialize little endian nbt.
