javascript - Uncaught reference error when I try to instantiate an object inside node console

Question

I am working with Node modules for the first time. I am trying to play around with FixedWidthParser module inside Node console. I followed instrucitons from the official NPM page.

First I installed it via: npm install fixed-width-parser

Then I required it in my console; const { FixedWidthParser } = require('fixed-width-parser');

Then I tried to create a new object:

const fixedWidthParser = new FixedWidthParser([
  {
    type: 'int',
    name: 'age',
    width: 2,
  },
  {
    name: 'name',
    width: 12,
  },
]);

But I am getting Uncaught ReferenceError: fixedWidthParser is not defined error. What is happening here?

Answer 1

Example from their documentation is not good. start property is mandatory when instantiating a FixedWidthParser, so just add that.
