Introducing Nexios: The Utility-First Python Web Framework

Meet Nexios, a revolutionary utility-first Python web framework that’s changing how developers build modern web applications. Unlike traditional frameworks that force you into rigid patterns, Nexios provides a comprehensive toolkit that adapts to your needs.

Nexios isn’t just another web framework—it’s a utility-first approach to web development. This means you get:

• Modular Architecture: Mix and match components as needed
• Rich CLI Tooling: Project scaffolding, code generation, and development tools
• Extensible Plugin System: Build and share custom functionality
• Community-Driven: Active ecosystem with nexios-contrib package

Getting started with Nexios is incredibly simple:

from nexios import NexiosApp
from nexios.http import Request, Response

# Create app with built-in utilities
app = NexiosApp(title="My Utility API")

@app.get("/")
async def basic(request: Request, response: Response):
    return {"message": "Hello from Nexios utilities!"}

@app.get("/users/{user_id:int}")
async def get_user(request: Request, response: Response):
    user_id = request.path_params.user_id
    return {
        "user_id": user_id,
        "name": f"User {user_id}",
        "email": f"user{user_id}@example.com"
    }

if __name__ == "__main__":
    app.run(host="127.0.0.1", port=8000)

Every endpoint you create automatically generates interactive API documentation. Visit /docs and you’ll find a complete Swagger interface.

• Debug toolbar for request inspection
• Profiling utilities for performance optimization
• Rich CLI for project management

The nexios-contrib package provides community-contributed extensions:

• ETag middleware for caching
• Trusted host middleware for security
• Redis integration
• And much more!

Built-in utilities for CORS, CSRF protection, secure headers, and multiple authentication backends.

For Rapid Prototyping: Get from idea to working API in minutes with automatic documentation and built-in utilities.

For Production Apps: Scale confidently with modular architecture, comprehensive middleware pipeline, and battle-tested components.

For Teams: Consistent tooling, shared utilities, and extensible architecture make collaboration seamless.

In upcoming posts, we’ll dive deeper into:

• Building production-ready APIs with Nexios
• Leveraging the community contrib package
• Advanced patterns with dependency injection
• Real-time applications with WebSocket support
