I use NuxtJS and I would like to read a parquet file from a URL. I get an error when I read the records using the cursor.next() method. The file seems to be of the right format because I can download it via the url and read it via this website: https://parquet-viewer-online.com
I forgot a dependency?
async readParquetFile(url) {
const parquet = require('parquetjs-lite');
const request = require('request');
let reader = await parquet.ParquetReader.openUrl(request, url)
let cursor = reader.getCursor();
let record = null;
while (record = await cursor.next()) { // error TypeError: cursor.buffer.readInt32LE is not a function
console.log(record);
}
}
TypeError: cursor.buffer.readInt32LE is not a function
