Javascript 如何在nodejs中读取.nlp文件

我正在使用节点nlp模块，如下所示。

const { NlpManager } = require('node-nlp');

const manager = new NlpManager({ languages: ['en'] });
// Adds the utterances and intents for the NLP
manager.addDocument('en', 'goodbye for now', 'greetings.bye');
manager.addDocument('en', 'bye bye take care', 'greetings.bye');
manager.addDocument('en', 'okay see you later', 'greetings.bye');
manager.addDocument('en', 'bye for now', 'greetings.bye');
manager.addDocument('en', 'i must go', 'greetings.bye');
manager.addDocument('en', 'hello', 'greetings.hello');
manager.addDocument('en', 'hi', 'greetings.hello');
manager.addDocument('en', 'howdy', 'greetings.hello');

// Train also the NLG
manager.addAnswer('en', 'greetings.bye', 'Till next time');
manager.addAnswer('en', 'greetings.bye', 'see you soon!');
manager.addAnswer('en', 'greetings.hello', 'Hey there!');
manager.addAnswer('en', 'greetings.hello', 'Greetings!');

// Train and save the model.
(async() => {
    await manager.train();
    manager.save("./model.nlp", true);
    const response = await manager.process('en', 'I should go now');
    console.log(response);
})();

这段代码生成“model.nlp”文件并运行良好
但是我想在没有训练的情况下重复保存这个“model.nlp”文件，并再次保存到另一个js文件中。
如何读取model.nlp文件并将其与“.process（）一起使用？
非常感谢您阅读

const fs = require('fs');
const { NlpManager } = require('node-nlp');

const data = fs.readFileSync('model.nlp', 'utf8');
const manager = new NlpManager();
manager.import(data);
