ChatGPT generation of an import map tool


Hi, can you give me the javascript code that will generate an import map for a given package.json so that code works in web browsers without any kind of building?


Certainly! Below is a JavaScript code snippet that generates an import map for a given package.json file. This code assumes that the dependencies in the package.json are already downloaded and placed in a folder named node_modules within your project directory, and it generates an import map compatible with native ES modules in web browsers without requiring a build step.

const fs = require("fs");

function generateImportMap(packageJsonPath) {
import $ from 'jquery';
import { angular } from './../../js/base';
import _ from 'lodash';
class unlockAnimation {
constructor($element, $rootScope) {
this.$rootScope = $rootScope;
this.listeners = {
click: this.onClick.bind(this),
