Bump advocates for a design-first approach to API development, emphasizing the importance of focusing on the API contract during the design phase to create consumer-friendly APIs. To support this approach, they have introduced the new "bump diff" command, which allows developers to track and summarize changes in API contracts directly from the CLI, facilitating easier collaboration and feedback within teams. This tool enhances the process by providing a quick summary of changes and enabling visual comparisons, which can be opened in a browser. Additionally, Bump has released a GitHub Action that automatically adds API contract changelogs as comments on pull requests, streamlining team discussions and feedback without delving into complex JSON diffs. The company continues to work on improving tools for identifying breaking changes and integrating with CI systems, reinforcing their mission of simplifying API version control.
