FastAPI Project

Steps 1-5 creates a working web framework application.

Steps 6-7 connects to the database

Steps 8-9 creates the application (endpoints, services to interact with database, password hashing)

Steps 10 adds authentication and authorization using JWT

---

1. Create a new folder MyProject

1. Initialize Python environment env with python3.9 -m venv env .

2. Create more folders flexboard and backend

3. In backend, create `requirements.txt

1. requirements.txt will have all the third party dependencies you need for your project.

4. Create a main Python class, main.py and add code from https://fastapi.tiangolo.com/#:~:text=Create%20a%20file,with to test

1. The app instance created from FastAPI is our web framework.
2. Gives us endpoints via @app decorator.
3. We can get .post, .get, .put, .delete, .patch, etc.

5. Start the program up and test

1. Module Name: uvicorn.
2. Parameters: main:app --reload.
3. Go to http://127.0.0.1:8000 to see if the app is running.

6. Create a new database in PGAdmin, database language shall be PostgreSQL as well

1. Usually a right click on Database shows Create > which then prompts a modal to create a new database.
2. Name it whatever you want and Save.

6a. Credentials

1. Create a new .env folder that will house all the environment variables.
   • Usually this file will have secrets coming from AWS, other areas.

6b. Create a config file and a session file

1. Create a config.py file that will house all the .env values.
2. Create a session.py file that creates new sessions.
3. Create a base_class.py that will have @as_declarative which grants us to manipulate tables.
4. Create a base.py file that will serve as a bootstrap.
5. In main.py import Base from tables.py to create the tables, bind runs the engine.
   • the .metadata object is NOT offered in autocomplete, but is available.
   • I learned that the classes we want to be tables *that extended Base) must be in the tables.py file
     • if not, the tables does not get created.

7. Tables are created via the code we have from SQLAlchemy

• users
• jobs

8. Create the users and jobs endpoints

9. Create the users and jobs services

10. Support Authentication and Authorization using JWT

11. Support the endpoints.

12. Testing.
