Hi @raxkumar

Can you provide the code where you use it so that we can investigate more?

Hi @NQPhuc ,

It was actually straight forward.
my usecase is to validate the dbml on the front-end [react]

import React from 'react';
import Parser from '@dbml/core'; // Ensure correct import

const App = () => {
  const parser = new Parser();
  return (
    <div>
      <h1>DBML Parser Test</h1>
    </div>
  );
};

export default App;

but when i import this package and start the react app, I am getting this error:-

Hi, you should import the parser like this

import { Parser } from '@dbml/core';

Also, what are the react version and @dbml/core version you are using?
