Hyparquet is a tiny and well-support parquet parser for the browser. It is written in pure javascript so it works well with webpack. I confirmed this works with webpack5 default config:

hyparquet-webpack-demo.js

import { asyncBufferFromUrl, parquetRead } from 'hyparquet'

// Load parquet data from a url using hyparquet
const url = 'https://hyperparam-public.s3.amazonaws.com/bunnies.parquet'
async function main() {
  const file = await asyncBufferFromUrl({ url })
  await parquetRead({
    file,
    onComplete: (data) => console.log(data),
    rowFormat: 'object',
  })
}
main()

webpack.config.js

module.exports = {
  mode: 'development',
  entry: './hyparquet-webpack-demo.js',
}
// output: ./dist/main.js
