How do I choose the right Yii application template for my project?
Choosing the appropriate Yii application template depends on the project size, structural needs and long-term goals. 1. The basic template is suitable for small projects, such as APIs or single-page applications; the advanced template supports multiple entry points and user roles, and is suitable for large and scalable applications. 2. Choose basic templates for simple projects, and choose advanced templates for complex systems. 3. Check whether the template contains pre-built functions, such as RBAC, AdminLTE theme or API structure, to save development time. 4. Considering the team size and future scalability, small teams can start from the foundation, and plan to grow directly using advanced templates. In short, start small, unless you are sure that more structure is needed, the template is just the starting point and can be reconstructed later.
