Injecting Common Dependencies
Implement common dependencies for database sessions, user authentication, or shared configuration across endpoints.
Intro to Common Dependencies
In FastAPI, dependencies are powerful. They help you share logic, manage resources, and keep your code clean.
Common dependencies are functions or classes that you reuse across many API endpoints. This prevents repetitive code and makes your application easier to maintain and test.
Think of them as reusable building blocks for your API.
Injecting Shared Configuration
Many applications need global settings, like API keys or database URLs. By injecting configuration, you can easily access these settings in any endpoint without resorting to global variables.
This keeps your configuration flexible and easy to update.
