How does provide and inject allow for deep component communication without prop drilling in Vue?
Jun 20, 2025 am 01:03 AM
In Vue, provide and inject are features for directly passing data across hierarchical components. The parent component provides data or methods through provide, and descendant components directly inject and use these data or methods through inject, without passing props layer by layer; 2. It is suitable for avoiding "propdrilling", such as passing global or shared data such as topics, user status, API services, etc.; 3. Note when using: non-responsive original values ??must be wrapped into responsive objects to achieve responsive updates, and should not be abused to avoid affecting maintainability.
