To Provide a good and fast work, i choose SQLAlchemy as a toolkit and performance, for the Database i choose SQLite a High performance Database and full of Features.We are Building an API with high performance built with FastAPI & SQLAlchemy, help to improve connection with your Backend Side to create a simple blog and Cruds with OAuth2PasswordBearer ⛏. Next Create the Following Files and Folders :.$ pipenv install -d -python 3.8 # install all dependencies (include -d for installing dev dependencies) # if you have multiple python 3 versions installed then # creating pipenv environment for python 3 ![]() Create a virtual environment for this project.I use pipenv a global python project pip install pipenv.Create a file requirements.txt and add the Preconfigured packages relate to the project. ![]()
