Build a simplified Twitter like version using flask. This project includes implementation of registration and login functionality, posting tweets, following or unfollowing users and obtaining user profiles. Flask is utilized for routing, apis, blueprints, HTTP methods. Integrate Postgresql in Supabase using SQLAlchemy. Token based authentication is implemented too.

Here are libraries in flask that being used for this twitter clone flask app :

1. flask
2. flask-sqlalchemy
3. pyscopg2-binary
4. flask-bcrypt
5. pyjwt
6. marshmallow

Before set up some packages and develop the flask app especially in Visual Studio Code, Please do some preliminary steps below:

1. Please add Python 311 Script first to the PATH (for Windows user only).
2. For example add this : "C:\Users\Aldi Andalan\AppData\Roaming\Python\Python311\Scripts" into PATH
3. In windows explorer, click -> this pc -> advance system settings -> advance -> environment variable -> edit path
4. Then put for instance "C:\Users\Aldi Andalan\AppData\Roaming\Python\Python311\Scripts" into the PATH and click ok.
5. After that, execute these commands in terminal, windows, command prompt or PowerShell in Visual Studio Code:

Here are some set ups before developing the flask app

python.exe -m pip install --upgrade pip --user

pip install pipenv --user

pip install flask --user 

pipenv --python 3.11  # or replace with your Python version

pipenv shell

pipenv install flask flask-sqlalchemy pyscopg2-binary flask-bcrypt pyjwt marshmallow

After all packages are installed, you can clone my codes and try running the apps. But before that make sure python interpreter selector is correct. You can check that in Visual Studio Code by pressing Ctrl+Shift+P all together simultaneously, then choose Python: Interpreter Selector and the choose the one with venv or virtual environment. It helps Visual Studio recognized your installed packages on pipfile that is obtained by setting up python and flask library above.

If all thet's steps are done, voila, you can run the flask application, run the flask application by using these commands in terminal:

pipenv shell

pipenv run flask run --debug

or

flask run --debug

After all of that, you can check or testing the APIs endpoints in postman app. Please visit API Documentation for intermediate and advance assignment at https://documenter.getpostman.com/view/29042682/2s9YeD7Cci and https://documenter.getpostman.com/view/29042682/2s9YeD8YYU to get clearer examples for body request in APIs enpoint which is used in this app.

In advance assignment there is a need to do unit testing using pytest. Hence, here is steps by steps on how to do it.

First, activate virtual environment

pipenv shell

Then, install pytest package

pipenv install pytest pytest-flask --dev

pytest

Runs the tests in a verbose mode, showing more details about the test execution.

pytest -v

Displays local variables in tracebacks when an error occurs during testing.

pytest --showlocals

forces pytest to display long tracebacks on failures.

pytest --tb=long  # Shows the long traceback

allows printing output to the console (useful for debugging).

pytest -s

If, pytest packages is not recognized by Visual Studio Code. Please try to delete pipfile.lock in locals and the try to re install packages by using pipenv install. If it does not work, the try to select correct python interpreter (ctrl+shift+P). It could be to virtuan environment in python interpreter is incorrect because of invalid folder location.
