A simple command line Node.js tool to read and write NBT files to JSON and back. Supports big, little and little-varint encoding.

Uses `prismarine-nbt` for serialization and deserialization, see https://github.com/PrismarineJS/prismarine-nbt for more info on schema.

### Usage 

via npx:

```sh

npx nbt-dump --help

```

via npm:

```

npm install -g nbt-dump

nbt-dump --help

```

```

usage, feel free to use natural language:

Parse an NBT file to JSON: 

    nbt-dump  [out-json-file] [little|big|varint]

    nbt-dump level.dat

        (Dump the contents of level.dat to terminal)

    nbt-dump level.dat to level.json

        (Dump the contents of level.dat to JSON)

    nbt-dump level.dat as little to level.json

        (Dump the contents of little endian encoded level.dat to JSON)

Write an JSON file to uncompressed NBT (defaults to big endian):

    nbt-dump write  [out-nbt-file] [little|big|varint]

    nbt-dump write level.json to level.dat

    nbt-dump write level.json to level.dat as little

You can also pipe the input to nbt-dump:

    cat level.dat | nbt-dump

    cat level.dat | nbt-dump to level.json

    cat level.json | nbt-dump write

    cat level.json | nbt-dump write to level.dat

```

### Example

If you do not specify endianness, it will automatically be inferred.

Parse to json, and back to nbt as big endian

```sh

$ nbt-dump level.dat level.json

* Dumping NBT file "file.nbt" to "file.json" as JSON

(as big endian)

$ nbt-dump write level.json level.dat

* Writing JSON from "file.json" to "file.nbt" as big endian

written!

```

Write as little endian

```sh

$ nbt-dump level.dat level.json

* Dumping NBT file "file.nbt" to "file.json" as JSON

(as big endian)

$ nbt-dump write level.json level.dat little

* Writing JSON from "file.json" to "file.nbt" as little endian

```
