scripts.js

The first part of the Contact Organizer's scripts.js file is the same implementation of image upload from the Pictorial Translator project:

"use strict";const serverUrl = "http://127.0.0.1:8000";class HttpError extends Error {    constructor(response) {        super(`${response.status} for ${response.url}`);        this.name = "HttpError";        this.response = response;    }}async function uploadImage() {    // encode input file as base64 string for upload    let file = document.getElementById("file").files[0];    let converter = new Promise(function(resolve, reject) {        const reader = new FileReader();        reader.readAsDataURL(file);        reader.onload = () => resolve(reader.result            .toString().replace(/^data:(.*,)?/, ''));        reader.onerror = (error) => reject(error);    });
