feat: add poetry

[szmktk]

This merge request adds support for poetry package management tool.

Using Poetry over requirements.txt offers several advantages:

• Advanced dependency resolver helps avoid conflicts and ensures compatibility.
• Generates a poetry.lock file for reproducible environments.
• Manages project metadata within a single pyproject.toml file.
• Simplifies common tasks with intuitive commands for dependency management.
• Allows specification of development dependencies separately from production ones.
• Supports PEP 517/518 standards for building Python projects.

I validated the backend app manually after building a new docker image.

Steps to test this locally:

1. checkout add-poetry branch
2. run make build command to build a new Docker image that contains dependencies managed by poetry
3. generate a token and verify endpoint operation using swagger-ui

Very nice feature for one of the next update. If We will need this good poetry :). I am open to discuss that topic.

[szmktk]

@miniMax18 what is there to discuss? In JavaScript you have package.json file with dependencies and devDependencies to tell actual runtime project dependencies from test/development ones. On top of that you have a package-lock.json (or yarn.lock or whaetver) that ensures every developer gets the same version of every dependency (including transitive dependencies).

These are (among many others) the problems that poetry aims to solve. Problems we did not yet face, but probably will and I'm convinced it's silly not to prevent them easily now. If we're going to have a stable CI/CD pipeline for this project that I insist on having poetry in.

@szmktk this some like "procedure" We need to know what we use(or will use). Thanks for that quality explain from JS world :). Nevertheless I know poetry tool from fast api product. I recommend @szmktk idea 👍 to adapt poetry in Zeton 💯

@szmktk this some like "procedure" We need to know what we use(or will use).

@miniMax18 Here's a breakdown of the most common poetry commands:

• Install and add a dependency and its sub-dependencies to the pyproject.toml file in the current directory: poetry add dependency

• Install the project dependencies using the pyproject.toml file in the current directory: poetry install

• Get the latest version of all dependencies and update poetry.lock: poetry update

• Execute a command inside the project's virtual environment: poetry run command

• Spawn a shell within the project's virtual environment: poetry shell

So when you would like to add a new library just use poetry add new_library instead of editing requirements.txt file. This command will edit both pyproject.toml and poetry.lock files for you. :wink:
