Export and import the ECMA6 class

How to export and use the ECMA6 class? This is what I am doing now:

parser.js

module.exports = class Parser {
   static parse() {
   }

   static doNow() {
   }
}

Now in another file, I am doing:

var Parser = require('parser')
Parser.parse();

When parse is called on Parser, I get an error saying 

SyntaxError: Unexpected identifier

with Parser highlighted.

What could be the reason for this? What is the correct to export and import the class?

You try to call your module in an absolute way this is what causes problem.

I recommend using an IDE as webstorm or atom to not have this kind of problem in the future

try this : 

var Parser = require('path/path/parser.js');
    Parser.parse();

for es6 is :

export default class Parser {
   static parse() {
   }

   static doNow() {
   }
}

import Parser from './path/path/parser';

It's easier and more readable to do it like this:

class Parser {
   static parse() {
   }

   static doNow() {
   }
}

module.exports = Parser;

and in the requiring module:

const Parser = require('./path/to/module');
Parser.doNow();
// etc.

I tested this and it seems the issue is the path of parser.

File Structor

-index.js

-parser.js

index.js

var Parser = require('./parser')
console.log('parser',Parser.parse());

parser.js

module.exports = class Parser {
   static parse() {
       return 'hello there'
   }

   static doNow() {
   }
}

Terminal

node index.js 
parser hello there
