Our first endpoint for PostgreSQL REST API will be a GET request. Cool, now we have everything we need to start using FastAPI! Learn the 3 ways to replicate databases & which one you should prefer. If you plan to use Python for web development, it will serve you well to become familiar with FastAPI. REST stands for representational state transfer. If you missed part 1 and need to set up some your initial docker-compose file and directory structure, you can check that out here if you want. First we will configure our python virtual environment .. Okay advanced may be a misnomer, but I did want to add one more thing for the pragmatic programmer (ugh I hate that I said that too) that is thinking ahead to well am I really going to put all my endpoints into api.py? PostgreSQL supports four standard procedural languages, which allows the users to write their own code in any of the languages and it can be executed by PostgreSQL database server. Up And Running With FastAPI part 1 Up and Running With FastAPI and Docker Environment and Setup ), Fast (per their documentation, as performant as NodeJS- and Go-based backends), No native frontend built into the framework (although I see this as a pro. PostgreSQL is not controlled by any corporation or other private entity and the source code is available free of charge. The naming of these files provides some foreshadowing of what our final product will be. Although it's not really FastAPI's forte, you can also use Jinja2 templates to serve dynamic HTML pages when needed. To make things easier, Hevo comes into the picture. REST APIs are stateless, meaning that calls can be made independently of one another, and each call contains all of the data necessary to complete itself successfully. FastAPI is a back-end API framework for Python. For more, review the official FastAPI documentation as well as the Dockerizing FastAPI with Postgres, Uvicorn, and Traefik tutorial. FastAPI includes a type system for your data validations as well as automatic API documentation. Put the certificate into the SSL folder as service.crt and service.key files. PostgreSQL REST API connection allows to create Restful applications with PostgreSQL as a database. So whilst the framework is best for backend REST APIs, you have the option to serve web pages if needed. PostgreSQL is a highly stable database backed by more than 20 years of development by the open-source community. Now, if you are mounting the directory as a volume, you should be able to just reload localhost:8080/docs. FastAPI is a high-performance API based on Pydantic and Starlette. 1. On 5th November 2022 / gigabyte m32u usb-c power delivery. These, like our Hello World function, return information that FastAPI will serialize for us. Finally, well use the DELETE clause on /users/:id to delete a specific user by id. A REST API should not rely on data being stored on the server or sessions to determine what to do with a call, but rather solely rely on the data that is provided in that call itself. It also gave two methods that can be used PostgreSQL REST API connection. However, there are drawbacks to REST API design. This will cover getting our backend API up and running! Since were using ES6 syntax, we can write getUsers instead of getUsers:getUsers, and so on. The common and simplest solution is to write a bunch of code that will check over and over if database is up and running before actual connection happen. Lets instead see what is inside books.py. Love podcasts or audiobooks? The Book class. Just a hardcoded list of Books. Next, we will configure a connection database from Fastify to PostgreSQL. Yes, it is fast, very fast and it is due to out of the box support of the async feature of Python 3.6+ this is why it is recommended to use the latest versions of Python.
