This repo uses VSCode's Dev Containers extension to standardize the development environment and avoid headache-inducing installation. All development will happen inside a Docker container which installs the same dependencies and versions on every developer's machine.

Installation

  1. Using Windows? First set up WSL 2.

    • Press Windows ⊞ -> "Turn Windows features on or off". Enable "Windows Subsystem for Linux".
    • Open Powershell as admin.
    • wsl --install
    • wsl --set-default-version 2
    • wsl --install -d Ubuntu-22.04
    • wsl --set-default Ubuntu-22.04
    • For more info: Microsoft documentation

  2. Install Docker Desktop.

    • Windows users: Make sure you select Use WSL 2 instead of Hyper-V if the option is presented.

  3. Open a new VSCode window and install Dev Containers extension from the Extensions menu.

  4. Open the Command Palette (Ctrl + Shift + P / Cmd + Shift + P) and select Dev Containers: Clone Repository in Container Volume.... Select GitHub, then enter fsek/WebWebWeb.git.

  5. After configuration has finished in the open terminal, it should say Done. Press any key to close the terminal. Open main.py and make sure VSCode has selected our Python interpreter from .venv folder: In the bottom right corner of VSCode it should say approximately Python 3.11.2 ('.venv': venv). Otherwise, open Command Palette -> Python: Select Interpreter and choose ./.venv/bin/python.

  6. Open a new Bash terminal (Ctrl + Shift + Ö) and run uvicorn main:app --reload. Terminal should have (.env), otherwise run source .venv/bin/activate.

  7. Go to http://127.0.0.1:8000/docs for the Swagger page automatically generated by FastAPI 🎉

  8. From now on, whenever you want to open this project: Open a new VSCode window and in Recent, find WebWebWeb in a unique volume [Dev Container]. Don't re-run Clone Repository... from step 3.

Play around

  1. Try calling some routes. You will find some routes fail since you are not logged in. Find the "Authorize" button and login using [email protected] dabdab.

  2. Call the GET /users/me route to view the logged in used. Change your last name to something creative by calling the PATCH /users/me.

  3. Evidently, the database is already filled with some starting data. This was done in the seed.py file when the server started. Go check it out!

  4. You can stop the FastAPI server anytime by entering Ctrl+C in the Bash terminal.

  5. Run python --version. Every developer will run the same python version thanks to containers.

  6. Run pip list to see all installed pip packages.

Pip installing new packages

Our project will need packages not native to Python. FastAPI is one such dependency. The actual package files are not checked into Git. Instead, a file listing the required packages exists in the project. The file requirements.txt lists all pip packages and versions needed.

To add a new package, add a new line in requirements.txt specifiying package name and exact version. Then, in terminal, while in the WebWebWeb folder, run pip install -r requirements.txt.
