The framework is tightly integrated with TypeScript, which may require significant time investment to learn and adapt for developers unfamiliar with the language.
Primary support is for TypeScript projects, limiting its utility in polyglot environments or teams that use a variety of programming languages and frameworks.
Version updates often include significant API changes, requiring substantial refactoring efforts for existing projects to maintain compatibility.
The documentation provides a high-level overview but lacks detailed guides and practical examples that would help developers understand complex use cases and best practices.
