Loco SDK for building plugins and shared utilities

Loco SDK

Official SDK for building Loco workflow plugins.

Installation

For Plugin Development

# Using pip
pip install loco-sdk

# Using uv (recommended)
uv pip install loco-sdk

For SDK Development

# Clone repository
cd packages/loco-sdk

# Install with dev dependencies using uv
uv venv
source .venv/bin/activate  # or .venv\Scripts\activate on Windows
uv pip install -e ".[dev]"

# Or with pip
pip install -e ".[dev]"

Quick Start

from loco_sdk import NodePlugin

class MyNode(NodePlugin):
    """My custom node."""

    async def execute(self, inputs: dict, context: dict) -> dict:
        """
        Execute node logic.

        Args:
            inputs: Node input values
            context: Workflow execution context with auth, sys_vars, etc.

        Returns:
            Output values dictionary
        """
        # Get authentication if needed
        auth = context.get("auth")
        if auth:
            headers = auth.get_header()
            # Use headers for API calls

        # Process inputs
        result = do_something(inputs)

        # Return outputs
        return {"result": result}

Authentication Helper

The SDK provides AuthContext to easily work with credentials:

from loco_sdk import NodePlugin, AuthContext

class MyNode(NodePlugin):
    async def execute(self, inputs: dict, context: dict) -> dict:
        # Wrap auth dict with helper
        auth = AuthContext(context.get("auth"))

        # Get Authorization header
        headers = auth.get_header()
        # Returns: {"Authorization": "Bearer <token>"}

        # Check token expiry
        if auth.is_expired():
            raise AuthenticationError("Token expired")

        # Access properties
        provider = auth.provider  # e.g., "google"
        scopes = auth.scopes      # OAuth scopes

        # Use in API calls
        response = await client.get(url, headers=headers)
        return {"data": response.json()}

Features

• NodePlugin Base Class: Simple interface for workflow nodes
• AuthContext Helper: Easy OAuth2/API key authentication
• Type Safety: Full Pydantic schema support (coming soon)
• Manifest Loading: Parse plugin.yaml files (coming soon)
• Testing: Comprehensive test suite with pytest

Development

See DEVELOPMENT.md for detailed development guide.

Quick Setup

# Install dependencies
make install

# Install pre-commit hooks (optional)
pip install pre-commit

Quick Commands

Use the Makefile for common tasks:

# Show all available commands
make help

# Run tests with coverage
make test

# Format code
make format

# Lint code
make lint

# Type check
make type-check

# Run all quality checks

CI/CD

This project uses GitHub Actions for CI/CD:

• CI Pipeline: Runs tests, linting, type checking on every push/PR
• Publish Pipeline: Automatically publishes to PyPI on releases
• Dependabot: Keeps dependencies up to date

See .github/workflows/README.md for details.
