Event driven architectures have become quite popular over the last few years. This is mainly due to their flexibility and ability to handle complex business scenarios. In this post, we will create a FastAPI Event Driven Architecture example using Redis. We will be covering the below aspects in this application Read more…
Dependency Injection is an important design pattern for building applications. Basically, every major framework implements Dependency Injection in some form or the other. However, a configuration-heavy approach adopted by some frameworks can lead to confusion. But FastAPI Dependency Injection system is pretty straightforward. It has a specially strong focus towards Read more…
Many times, we need to run some application tasks without making the API consumer wait for their response. In such cases, it is a good practice to run such tasks in the background. In this post, we will learn how to use FastAPI Background Tasks. If you are new to Read more…
In this post, we will learn how to perform FastAPI Path Parameter Validation. We will specifically also learn how to use the Path() function to handle the validations in a declarative approach. Using the Path function is quite similar to using the Query function. In other words, we can declare Read more…
In this post, we will learn how to perform FastAPI Query Parameter validation. In particular, we will look into the use of Query function that allows us to perform validations in a declarative manner. If you are not aware of query parameters in FastAPI, you can check out this detailed Read more…
In this post, we will learn how to use FastAPI Request Body. We will use Pydantic BaseModel class to create our own class that will act as a request body. When we need to send some data from client to API, we send it as a request body. In other Read more…
In this post, we will learn how to use FastAPI query parameters while creating API endpoints. Query parameters are absolutely vital to build flexible APIs. As the name suggests, endpoints with query parameters can often help clients to query for specific data based on dynamic parameters. In the last post, Read more…
Path parameters are one of the first things you need to use when building REST APIs. In this post, we will learn how to use FastAPI path parameters with validations. Validations are a key aspect of any robust application. FastAPI uses Pydantic to handle data validations under the hood. Therefore, Read more…
In this first post of a new series, we will get started with FastAPI. We will create our first FastAPI application from scratch. In doing so, we will understand the basic moving parts of a typical FastAPI application. Pre-requisite for learning FastAPI is to have basic knowledge of Python. Also, Read more…
