When we start serving HTML files with our FastAPI application, we need a way to send images, CSS- and JavaScript files without creating an endpoint for each file. Let us solve this problem with a static route. This post is part of my journey to learn Python. You find the code for this post in …
Last week we added Alembic to our to-do app to be ready for upcoming changes to the tables. In this post we extend our FastAPI application, but in an unexpected direction: we add a web interface. Let us find out how we can do that. This post is part of my journey to learn Python. …
Our current way to create the tables in the database when we run the application works fine until we need to extend an existing table. Then SQLAlchemy will not do that for us, and we must make the change manually. With Alembic we have a solution for that problem that works great with SQLAlchemy. Let …
Last week we moved from an in-memory data store to SQLAlchemy and persist our tasks inside an SQLite database. We have two things we need to optimize, or else we end up with problems along the way. This post is part of my journey to learn Python. You find the code for this post in …
Until now we kept our data in a variable. While that worked with an example application, the data vanishes as soon as we restart our API. To get a more realistic application, we need to persist data for a longer time. Let us explore how we can integrate SQLAlchemy with FastAPI. This post is part …
As we saw with the OAuth2 and JWT example, our main.py file can grow quickly. If we keep adding features, the file will be unmaintainable in no time. For Flask we used Blueprint to split up the application , for FastAPI we can use APIRouter to do the same. This post is part of my …
While I was preparing the next post, I run into an annoying warning that I wanted to fix before I add one additional feature to the minimalistic to-do application. Let us explore what I had to do to find the reason for the warning and how I could fix the problem. This post is part …
The HTTP basic authentication from last week has been working, but it feels a bit messy. When we search for a more current style of authentication, we end up with OAuth2 and JWT. There is an example in the FastAPI documentation that I changed a bit to use a different library for JWT, store the …
There are many ways we can secure an endpoint in FastAPI. As a first approach we explore HTTP basic authentication, a not so secure way but it allows us to get a first glimpse into the different parts of FastAPI that we need to protect an endpoint. This post is part of my journey to …
With FastAPI we get the OpenAPI specification and the Swagger interactive documentation for free. While that is a great help, the automatically generated documentation is not always as helpful as it could be. Let us look for ways in which we can fine-tune the documentation. This post is part of my journey to learn Python. …
