Case Study: Colruyt accelerates code modernization with Moderne and OpenRewrite

Colruyt speeds Spring Boot 3 upgrades across the organization in one-line code changes with Moderne

Colruyt, a major Belgian retailer, faced the challenge of upgrading its central software libraries to newer frameworks like Spring Boot 3. The manual process was time-consuming and complex. To address this, they utilized OpenRewrite recipes from Moderne to automate these large-scale code migrations.

The solution implemented by Moderne used OpenRewrite to automatically refactor and upgrade code, which allowed Colruyt's central expert developers to quickly gain trust in the process and achieve immediate impact across the entire organization. This enabled them to move code forward efficiently and consolidate their frameworks. Moderne provided the tools and documentation that empowered Colruyt's team to not only use the recipes but also to contribute their own fixes and features back to the open-source project.
