Browsers have improved a lot over the past years. It's now possible to do web development without requiring any build tools, using the native module loader of the browser. We think this is a great fit for FicusJS, and we recommend this as a general starting point.
Build tools can quickly add a lot of complexity to your code, and make your code reliant on a specific build setup. We think it's best to avoid them during development, or only add them for light transformations if you know what you're doing.

If your project is using an existing build tool, FicusJS is fully compatible and can work alongside other libraries and frameworks.
