The library supports multiple platforms (Browser, NodeJS and Deno).

const { OTBReader, OTBWriter } = require('@v0rt4c/ot-otb');

import { OTBReader, OTBWriter } from '@v0rt4c/ot-otb';

import { OTBReader, OTBWriter } from 'https://deno.land/x/v0rt4c_otb@0.1.0/mod.ts';

Reading the .OTB file is really easy. Simply create a new instance of the OTBReader and provide it with the .OTB file buffer. The buffer param must be a Uint8Array. Then call the parse method to get the RootNode.

const reader = new OTBReader(otbBuffer);
const rootNode = reader.parse();

console.log(rootNode);

Output

RootNode {
  _itemsMajorVersion: 1,
  _itemsMinorVersion: 3,
  _itemsBuildNumber: 17,
  _children: [Item, Item, Item, Item, ..., ...]
  }

Writing the .OTB file back to its original form is also really easy. Simply create a new instance of the OTBWriter and provide it with the RootNode. Then call the writeBuffer method. This will give you the .OTB buffer back as the return value.

const writer = new OTBWriter(rootNode);
const buffer = writer.writeBuffer();

The RootNode class holds information about the .OTB file such as the versions & buildnumber. It also holds all the items in the .OTB file in an array.

The Item class holds information about an item, such as the server ID, client ID, flags & attributes.

The Item constructor takes no arguments.
