This tutorial will explain the steps to determine the file size in bytes using NodeJS
NodeJS provides the inbuilt fs library which can be used for all file related methods. The file size can also be determined using this library
Create a reference variable for fs libray and use the statSync method on the required filePath
const fs = require("fs");
const path = require("path");
const filePath = path.normalize(path.join(__dirname, "../temp/", fileUrl))
const stats = fs.statSync(filePath);
const sizeInBytes = stats.size;
