Can't Maintain is a web-based game focused on improving recognition of effective React component API design. The game presents users with pairs of component APIs and challenges them to identify which interface demonstrates better practices, such as clearer prop naming and more maintainable structures. Each challenge draws from real conventions found in React, MUI, and production codebases, aiming to help players internalize patterns that lead to cleaner, more robust APIs.
The platform offers a set of 10 side-by-side code challenges per session and does not require signup to play. Sessions are designed to be completed in about three minutes, making it suitable for quick practice. The game includes daily and weekly challenge seeds, providing ongoing variety for returning users. Explanations are provided for each pattern, covering topics such as callback naming, boolean props, and prop specificity, to reinforce learning and clarify why certain API choices are preferable.
Can't Maintain is part of a broader series of educational games covering topics like TypeScript, UX design, SEO, and development patterns. The game is open source and community-driven, inviting contributions of new challenges, categories, and improvements.
