Failed to configure tokenizer

[lspliner]

var Az = require("az"); var tokens = Az.Tokens(); tokens.append(input, {}); tokens = tokens.done();

This code throws exception on line 3: config = config ? Az.extend(this.config, config) : this.config; ReferenceError: Az is not defined

Добрый день.

linux, node v9.11.1

Такой код (без config) работает:

const Az = require('az');
const tokens = Az.Tokens('Мама мыла раму').done(['SPACE'], true));

Такой код (Tokens вызывается с config):

const Az = require('az');
const tokens = Az.Tokens('Мама <b>мыла</b> раму', { html: true })
  .done(['SPACE'], true)
);

Ошибка:

/home/node_modules/az/dist/az.js:1700
        this.config = config ? Az.extend(defaults, config) : defaults;
                               ^
