Dependency Injection (การฉีดพึ่งพา) Hard Skill
Dependency Injection is a software design pattern that allows the removal of hard-coded dependencies and makes it possible to change them at runtime or compile time, promoting loosely coupled and more testable code.
Expertise Level
Level 1
Basic
1. Understands the concept of dependency and dependency injection.
2. Can explain the benefits of decoupling components.
3. Knows basic implementation using constructor or setter injection.
Level 2
Intermediate
1. Can implement dependency injection in a project using frameworks or manual coding.
2. Understands different injection types (constructor, setter, interface).
3. Able to manage object lifecycle and scope with dependency injection.
Level 3
Advanced
1. Designs complex architectures leveraging dependency injection for high modularity and testability.
2. Integrates dependency injection with advanced patterns like inversion of control containers.
3. Optimizes performance and manages dependencies in large-scale applications.
