> While RequireJS has its merits and advantages, it might be worth considering replacing it with another technology.
> A bundle loader like Webpack would open up a number of possibilities:
> - use of ES6 modules, which immediately improves tooling support
> - use TypeScript, which improves tooling support even more
> - a manageable code base would enable refactoring of the JavaScript code so that no logic happens in the module initialization code,
> which in turn would make it possible to write tests for the JavaScript logic.
> As a POC I created a NodeJS project that transforms the current dashboardv2 code into Webpack bundles and demonstrates
> that the UI is able to work without RequireJS.
> Right now the JavaScript sources and index.html are used unchanged,
> but the next step would be to start converting the source to ES6 modules.
> Here is the code: https://github.com/csabakoncz/atlas-newui
> The most important file there is `webpack.config.js` that takes over the role of RequireJS.config.
> The other file of interest might be `src/index.ts` which demonstrates the ability to use TypeScript code even now.
