framex-kit 0.3.2

A lightweight plugin injection framework for Python.

FrameX

FrameX is a lightweight, pluggable Python framework designed for building modular and extensible algorithmic systems.\

It provides a clean architecture that supports dynamic plugin registration, isolated execution, and secure invocation, making it well-suited for multi-algorithm collaboration, heterogeneous task scheduling, and distributed deployments.

Each algorithm can be developed, deployed, and loaded as an independent plugin, achieving infinite scalability.

Key Features

• Plugin-Based Architecture
  Algorithms are encapsulated as independent plugins, which can be added, removed, or updated without impacting others.
• Distributed Execution with Ray
  Optional Ray integration delivers high concurrency, high throughput, and resilience against blocking tasks.
• Cross-plugin Calls
  Enables interaction between local and remote plugins. If a plugin is not available locally, the system automatically routes the request to the corresponding cloud plugin.
• Backward Compatibility
  FrameX can seamlessly forward requests to standard FastAPI endpoints, enabling smooth integration without code changes.
• Streaming Support
  Native support for streaming responses, suitable for long-running or large-scale inference tasks.
• Built-in Observability
  Integrated logging, tracing, and performance monitoring to ease debugging and root-cause analysis.
• Flexible Configuration & Tooling
  Clean configuration management (.toml, .env) plus scaffolding, packaging, and CI/CD integration for automation.

Installation

pip install framex-kit

1) Execute by loading your plugin

Create foo.py file

from typing import Any
from pydantic import BaseModel

from framex.consts import VERSION
from framex.plugin import BasePlugin, PluginMetadata, on_register, on_request


__plugin_meta__ = PluginMetadata(
    name="foo",
    version=VERSION,
    description="A simple Foo plugin example",
    author="touale",
    url="https://github.com/touale/FrameX-kit",
)


class FooModel(BaseModel):
    text: str = "Hello Foo"


@on_register()
class FooPlugin(BasePlugin):
    def __init__(self, **kwargs: Any) -> None:
        super().__init__(**kwargs)

    @on_request("/foo", methods=["GET"])
    async def foo(self, message: str) -> str:
        return f"Foo says: {message}"

    @on_request("/foo_model", methods=["POST"])
    async def foo_model(self, model: FooModel) -> str:
        return f"Foo received model: {model.text}"#   

Run the following command to start the project creation process:

Application Scenarios

• Quick Onboarding & Project Setup
  New developers can rapidly bootstrap projects and reuse existing algorithms via remote calls, without accessing legacy code.

• Multi-Team Parallel Development & Isolation
  Different teams manage their own isolated plugin spaces. Access control ensure security and reduce interference.

• Hybrid Deployment & Smooth Migration
  Supports hybrid calls with other FastAPI services, dynamic endpoint registration, and multi-instance FrameX deployment with inter-instance communication.

• Modular Delivery & Commercial Licensing
  Deliver selected algorithm modules locally to clients while keeping others as remotely callable services. This supports licensing, pay-per-use, and flexible business models.
