As API projects grow in complexity, managing OpenAPI descriptions effectively becomes crucial, especially for teams aiming to turn architectural ideals into reality. The Redocly CLI offers solutions like the split, bundle, and join commands to handle large OpenAPI files and facilitate development. The split command breaks down a large OpenAPI file into manageable parts, enhancing efficiency by allowing developers to work with smaller, separate files linked via $ref references. This format is beneficial for development but may be bundled back into a single file for publishing, as many tools require a single input file. Conversely, the join command allows multiple OpenAPI files from different teams, such as those working on microservices, to be merged into a unified API description, ensuring a consistent user experience. This approach supports independent team workflows while maintaining a coherent API structure. As API projects advance, adopting such tools can improve both the developer experience and the end-user experience by providing a more organized and adaptable API management process.
