Bug Loading data for second time in Electron app

[martidinho8]

Hi All,

I used this package in combination with electron in vue.js. There is however a problem in loading the data in for the second time.

When I run this function in vuejs(in the methods);

async try_run_data() {


  var parquet = require("../../node_modules/parquetjs-lite/parquet");

  console.log(1);

  let reader = await parquet.ParquetReader.openFile(
    "./src/assets/data/parquet.snappy"
  );


  //console.log(reader)
  console.log(2);

  // create a new cursor

  let cursor = reader.getCursor();

  // read all records from the file and print them
  let record = null;
  // while (record = await cursor.next()) {
  //   var a = record
  // }
  // console.log(a)

  let count = 0;
  let check = [];

  while ((record = await cursor.next())) {
    count++;
    // newobj[] = {};
    // check.append(record)
    check.push(record);
    // console.log(record)
    // var a = {record}
    if (count == Infinity) {
      break;
    }
  }

  reader.close();

  console.log(3);

  console.context().log(check);

  var a = [];
  var b = [[], [], [], [], [], [], [], [], [], [], [], [], [], [], [], []];

  for (let i = 0; i < check.length; i++) {
    a.push(check[i]["__index_level_0__"]);
    b[0].push(check[i]["000"]);
    b[1].push(check[i]["001"]);
    b[2].push(check[i]["002"]);
    b[3].push(check[i]["003"]);
    b[4].push(check[i]["004"]);
    b[5].push(check[i]["005"]);
    b[6].push(check[i]["006"]);
    b[7].push(check[i]["007"]);
    b[8].push(check[i]["008"]);
    b[9].push(check[i]["009"]);
    b[10].push(check[i]["010"]);
    b[11].push(check[i]["011"]);
    b[12].push(check[i]["012"]);
    b[13].push(check[i]["013"]);
    b[14].push(check[i]["014"]);
    b[15].push(check[i]["015"]);
  }

  console.context().log(a);
  console.context().log(b);
},

I get the console logs 1 to 3 and the console log of the data set I read in via parquet. However after restarting the electron app. I get a problem, the function only runs console.log(1). Meaning it does not run into:

let reader = await parquet.ParquetReader.openFile(
"./src/assets/data/parquet.snappy"
);

Is this a bug or a code mistake?

Note; I also changed in vue the await functions into promises. This also did not give the result I looked for :-(
