Retool introduces Modules, a new feature designed to enhance the reusability and composability of components and queries across different applications, addressing previous challenges in adhering to programming principles like DRY and composability within its editor. Modules allow developers to create a shared library of reusable components and queries, making updates instantly reflected across all applications they influence, thereby promoting efficiency and reducing the need for duplicated efforts. Drawing parallels to React, Modules enable communication between the parent app and the module through data and query inputs, facilitating organization and customization for complex use cases like admin panels and customer lookup apps. This innovation empowers teams to tailor their Retool applications to specific needs while maintaining a streamlined management process, supporting diverse teams such as support and sales with specialized functionalities. Modules represent a strategic move by Retool to help developers manage an increasing number of high-performing applications, encouraging the creation and use of a library of modules to meet varied operational requirements.
