Using ES6 the javascript becomes a little cleaner
handleFiles(input) {
const file = input.target.files[0];
const reader = new FileReader();
reader.onload = (event) => {
const file = event.target.result;
const allLines = file.split(/\r\n|\n/);
// Reading line by line
allLines.forEach((line) => {
console.log(line);
});
};
reader.onerror = (event) => {
alert(event.target.error.name);
};
reader.readAsText(file);
}
