Hey there, fellow developers! Today, we’re taking a fun journey into the heart of FastAPI and uncovering the magical world of middleware. Whether you’re a seasoned software wizard or just getting your feet wet in the realm of development, fear not! We’ll make sure you grasp every concept with ease and maybe even a sprinkle of excitement.
What is Middleware?
- Imagine you’re at a grand feast, and the food is being prepared in the kitchen by master chefs. The waiter serves you the delicious dishes one by one. Now, think of middleware as the secret passage between the kitchen and the dining hall. It intercepts your requests, adds some special seasoning (or logic) to them, and then serves them to you, all without disrupting the flow of the feast.
- In FastAPI, middleware acts as this behind-the-scenes magician, enhancing and customizing your API experience without you even realizing it.
- In one line it is a bidirectional filter.
