Re.Pack is a Webpack-based toolkit to build your React Native application with full support of the Webpack ecosystem

Re.Pack (@repack_rn) is an Open Source toolkit that uses Webpack 5 and React Native CLI's plugin system to allow developers to bundle React Native apps using Webpack features. It makes Webpack understand React Native codebases and produce bundles that can be run by React Native applications.

The toolkit provides developers with the full Webpack ecosystem of plugins and loaders that can be used in building advanced mobile applications that benefit from the code splitting including:

super apps
mini apps
modular apps
underperforming apps
apps that require advanced custom solutions

Modular apps

Use code splitting to expose different functionalities or different UIs based on the user's details.

‍
Taking an e-learning app for example:
Code splitting allows developers to separate student’s and teacher’s functionalities. Thanks to that the application loads either of them while decreasing the initial download size of the app and improving startup performance by loading only relevant code.

‍

Super apps

Streamline the development and simplify management of your apps on the App Store and Google Play

Both super apps and mini apps stores are applications built from smaller, dedicated mini apps. Instead of having multiple super apps and mini apps on the App Store and Google Play combine them into a single one while streamlining the development and simplifying management.

‍

Better performing apps

Provide better user experience by improving startup performance of your React Native apps

Thanks to the loading-on-demand functionality load only the necessary pieces of the code and postpone the load of others while improving startup performance (TTR/TTI) in underperforming apps.

‍

Advanced and custom solutions

Use Re.Pack to create solutions for custom needs in React Native apps using advanced features and configuration options

Re.Pack allows developers to leverage all Webpack features and enables them to create custom and extraordinary solutions which would otherwise require hacky, unstable or unmaintainable setup.
