Utilizing Webpack to bundle libraries for package management

Hello there,

I am currently dealing with a legacy application that relies on various libraries such as jQuery, moment.js, and underscore. These libraries were manually assembled and added to the repository in a loosely coupled manner. My goal is to transition this setup to a more modern package manager like npm or yarn to simplify the management of dependencies when updates are needed.

Although I have attempted to use webpack for this purpose, I have encountered difficulties in bundling these libraries in a way that allows them to be globally accessible (even though I understand that this goes against best practices, I am constrained by the inability to rewrite the existing legacy code).

Is it feasible to achieve my desired outcome?

For example, could I create a dependencies.js file containing require(xx) statements, and then load it as a script in the browser to make the libraries globally available instead of individually loading each one from a local source?

Answer №1

Utilizing webpack, you have the ability to import all libraries in your entry point file and incorporate them into the global scope. By doing this, you can easily invoke your previous code through a dynamic import, ensuring that global variables are properly configured.

import $ from "jquery"
import _ from "lodash"
import moment from "moment"

window.$ = $
window._ = _
window.moment = moment

import("./yourOldCode")
