SYSTEM DOCUMENTATION & REQUIREMENTS

What problem does it solve?

This skill simplifies the creation of in-process request handlers for NeMo Platform plugins, eliminating the need for complex scheduler or backend dispatch logic for simple tasks.

Core Features & Use Cases

  • Unified Interface: Automatically exposes functions as both CLI subcommands and HTTP routes.
  • Streaming Support: Native support for NDJSON streaming with automatic heartbeat injection to prevent connection timeouts.
  • Use Case: Developers can use this to quickly build and mount custom API endpoints for their plugins, such as a greet function or a real-time data processor, with built-in Pydantic validation and dependency injection.

Quick Start

Use the plugin-function skill to define a new NemoFunction class with a spec_schema and mount it to your plugin service using add_function_routes.

FAQPage Schema
How do I expose a Python function as both a CLI command and an HTTP route in FastAPI?▼

You can expose a Python function as a CLI command and HTTP route by defining a NemoFunction class with a spec_schema, which automatically generates CLI flags and mounts API routes using Pydantic validation.

How do I add NDJSON streaming responses with heartbeat injection to a NeMo plugin?▼

To add NDJSON streaming responses to a NeMo plugin, use the plugin-function skill to define your handler, which provides native streaming support and automatically injects heartbeats to prevent connection timeouts.

Can I use Pydantic schemas for spec validation and dependency injection in NeMo Platform plugins?▼

Yes, you can use Pydantic schemas for spec validation and dependency injection in NeMo Platform plugins by defining a NemoFunction class that leverages these schemas for automated validation and route mounting.

What is the best way to build in-process request handlers for NeMo Platform plugins?▼

The best way to build in-process request handlers for NeMo Platform plugins is using the plugin-function skill, which eliminates complex scheduler or backend dispatch logic for simple tasks.

Do I need a complex scheduler to mount custom API endpoints for NeMo plugins?▼

No, you do not need a complex scheduler to mount custom API endpoints for NeMo plugins because the plugin-function skill creates in-process request handlers to simplify development for simple tasks.

How does automated CLI flag generation work with Pydantic schemas in NeMo plugins?▼

Automated CLI flag generation works by reading your Pydantic spec_schema within the NemoFunction class, translating the defined validation rules directly into CLI subcommands and HTTP interfaces.
