No(t) Rollup → Nollup
Rollup compatible bundler, designed to be used in development. Using the same Rollup plugins and configuration, it provides a dev server that performs quick builds and rebuilds, and other dev features such as Hot Module Replacement.
Rollup is an incredible tool, producing very efficient and minimal bundles. Many developers use it already to build libraries, but I wanted to use it to build apps. However, Rollup focuses mostly on the production side of things, with almost no developer experience other than basic file watching. Using Rollup in development can be incredibly slow with rebuilds taking seconds because of all of the optimisations Rollup does for you (ie. tree-shaking, scope-hoisting).
Nollup aims to fill in that gap. Using the same Rollup plugins and configuration, you can use Nollup to run a development server that generates a development bundle. It does no optimisations, making it really quick at rebuilding, also allowing for Hot Module Replacement using existing module.hot conventions for compatibility with existing libraries.

Nollup provides four ways to use it:
For the majority of projects, it is recommended to use the CLI approach.
The examples show different features of Nollup, including examples for React and Preact based projects with HMR. They also demonstrate how to use Nollup in development and Rollup to build production builds. Highly recommended to check them out here.
See documentation about Hot Module Replacement here.
See documentation about supported Rollup config options here.
Some Rollup plugins provide additional support for Nollup projects. You can find the list here.
Nollup provides additional plugin hooks for plugin authors to implement features such as HMR. See more information here.
- Only Rollup configurations that make sense in development are implemented.
- Might be some inconsistencies with Rollup, but should be fine for majority of projects.
- No support for live-bindings, but circular dependencies are supported.
