electron使用new Worker写入文件导致浏览器崩溃

main.js

let data1 = [];
let data2 = [];
for (let i = 0;i < 500000;i++) {
    let j = i * 500.0 / 60000.0;
    data1.push([j, 200 * Math.random() + 100]);
    data2.push([j, 400 * Math.random() + 100]);
}
let params = {
    type: 'xls',
    data: { data1, data2 },
    filename: 'text.xls',
};
let worker = new Worker('worker.js');
worker.onmessage = (ev) => {
   console.log('写入完成');
   worker.terminate();
};
worker.postMessage(params);

worker.js

const fs = require( "fs" );

self.onmessage = function (e) {
    let data = e.data;
    console.log(data);
    if (data.type === "xls") {
