platform-base-lib 0.1.4

Common library for Base Setup

Platform Base Library

platform_base_lib is a Python library designed as a foundational component for managing project infrastructure using gRPC protocol buffers. This project simplifies and standardizes common tasks such as communication setup, protobuf compilation, and offering shared functionalities for base setup.

Features

• gRPC Support: Automatically compile .proto files to Python bindings for gRPC services (*_pb2.py and *_pb2_grpc.py).
• Declarative Configuration: Simplifies package setup using setup.cfg and supports easy installation and dependency management.
• Extensible: Provides functionality to build on top of existing gRPC infrastructure.

---

Getting Started

Prerequisites

Ensure you have the following installed:

• Python >= 3.12
• Pip >= 20.x.x
• Build tools for Python packaging:

  pip install -r requirements.txt
  

If you're working with the gRPC protocol buffers, you’ll also need:

• grpcio and grpcio-tools for protocol buffer compilation.

---

Installation

Install From Git

You can install the platform_base_lib directly from the source repository:

pip install git+https://github.com/KJBNAgtechPlatform/PlatformBaseLib.git@main#egg=platform_base_lib

Install From PyPI

To install the library from PyPI (after publishing):

pip install platform_base_lib

---

Project Commands Cheatsheet

Protobuf File Compilation

Run the custom generate_protos command to compile .proto files into Python bindings:

python setup.py generate_protos

Package Building

To generate source (.tar.gz) and wheel (.whl) distributions:

python setup.py sdist bdist_wheel

The distribution files will be located in the dist/ folder.

2. Key Components

Protobuf Management

All .proto files are stored under platform_base_lib/infra/grpc/proto/. These files define gRPC services and message types.

Run the generate_protos command to compile .proto files into Python bindings:

python setup.py generate_protos

This generates:

• auth_pb2.py: Contains gRPC messages.
• auth_pb2_grpc.py: Contains gRPC service stubs.

Example Usage:

from platform_base_lib.infra.grpc.proto import auth_pb2, auth_pb2_grpc

class MyAuthService(auth_pb2_grpc.AuthServiceServicer):
    def Login(self, request, context):
        # Process login requests
        return auth_pb2.LoginResponse(success=True)

Dependencies

Listed in requirements.txt, and must be installed for the package to work:

grpcio==1.56.2
grpcio-tools==1.56.2
pytest==7.4.2
numpy==1.25.0
pandas==2.1.0

For development dependencies, use:

pip install -e .[dev]
