Routilux ⚡

简体中文

Routilux — Event-driven workflow orchestration. Too many pipelines to tame? One event queue for orchestration, concurrency, and resume-from-checkpoint. Build in minutes, recover anytime.

✨ Why Routilux?

🚀 Event queue: Non-blocking, one model for sequential and concurrent execution
🔗 Flexible wiring: Many-to-many routines, smart routing
📊 State built-in: Execution state, metrics, history out of the box
🛡️ Error policies: STOP / CONTINUE / RETRY / SKIP with automatic recovery
⚡ Concurrent execution: I/O parallelized without blocking the main flow
💾 Checkpoint & resume: Save and restore at any node; survive interruptions
🎯 Production-ready: Error handling, tracing, and monitoring
🎨 Simple API: Flow auto-detection; fewer parameters in most cases

🎯 Perfect For

Data Pipelines: ETL processes, data transformation workflows
API Orchestration: Coordinating multiple API calls with complex dependencies
Event Processing: Real-time event streams and reactive systems
Workflow Automation: Business process automation and task scheduling
Microservices Coordination: Managing interactions between services
LLM Agent Workflows: Complex AI agent orchestration and chaining

📦 Installation

⚡ One-Line Install (Recommended)

# Mac / Linux - Auto-detects best method (uv > pipx > pip)
curl -fsSL https://raw.githubusercontent.com/lzjever/routilux/main/install.sh | bash

# Or with wget
wget -qO- https://raw.githubusercontent.com/lzjever/routilux/main/install.sh | bash

Installation options:

# Use pipx instead of uv
METHOD=pipx curl -fsSL https://raw.githubusercontent.com/lzjever/routilux/main/install.sh | bash

# Install specific version
VERSION=0.14.0 curl -fsSL https://raw.githubusercontent.com/lzjever/routilux/main/install.sh | bash

Recommended: Isolated CLI Installation (pipx)

The best way to install Routilux CLI without affecting your system:

# Install CLI with isolated environment
pipx install "routilux[cli]"

# Use anywhere
routilux --help
routilux run workflow.yaml

Why pipx?

✅ Creates isolated virtual environment (no dependency conflicts)
✅ CLI available globally
✅ Easy to update: pipx upgrade routilux
✅ Works on Mac and Linux

Alternative: Modern (uv tool)

Using uv (faster than pipx):

# Install
uv tool install "routilux[cli]"

# Use
routilux --help

macOS / Linux: Homebrew

# Add tap and install
brew tap lzjever/routilux
brew install routilux

# Or directly
brew install lzjever/routilux/routilux

Standard pip Install

For library use or development:

# Library only
pip install routilux

# With CLI support
pip install "routilux[cli]"

Development Setup with uv (Recommended)

This project uses uv for fast dependency management. Install uv first:

curl -LsSf https://astral.sh/uv/install.sh | sh

Then set up the development environment:

Recommended: For active development

# Install package with all development dependencies (recommended)
make dev-install

# Or manually with uv (dev group is installed by default)
uv sync --group docs --all-extras

Alternative: Dependencies only (for CI/CD or code review)

# Create virtual environment and install dependencies only (without installing the package)
# Useful for: CI/CD pipelines, code review, or when you only need development tools
make setup-venv

# Later, if you need to install the package:
make install

Understanding dependency groups vs extras:

Dependency groups (dev, docs): Development dependencies that are not published to PyPI. The dev group is installed by default with uv sync.
Extras: Currently none, but may be added in the future.

All make commands will automatically use uv if available, otherwise fall back to pip.

Development Install (Legacy - using pip)

For development with all dependencies using pip:

pip install -e ".[dev]"
# Or using Makefile
make dev-install

🖥️ CLI

Routilux includes a command-line interface for workflow management:

# Install with CLI support
pip install routilux[cli]

# Run a workflow
routilux run --workflow flow.yaml

# Start server
routilux server start

# See all commands
routilux --help

CLI Commands

routilux init - Initialize a new project with example files
routilux run - Execute a workflow from a DSL file
routilux server - Start the HTTP server for API access
routilux job - Submit and manage jobs
routilux list - List available routines or flows
routilux validate - Validate a workflow DSL file

See CLI Documentation for details.

Server with Flow Loading

Start the HTTP server with flow auto-loading:

# Start server with flows directory
routilux server start --flows-dir ./flows --port 8080

# Built-in routines (Mapper, Filter, etc.) are automatically available
# Flows from ./flows/*.yaml are loaded at startup
# Hot reload enabled - flow files are watched for changes

Job Management

Submit and manage jobs via CLI:

# Submit job locally
routilux job submit --flow myflow --routine processor --data '{"input": "value"}'

# Submit job to remote server
routilux job submit --server http://localhost:8080 --flow myflow --routine processor --data '{}'

# Check job status
routilux job status <job_id>

# List jobs
routilux job list --flow myflow

🚀 Quick Start

For development with all dependencies using pip:

pip install -e ".[dev]"
# Or using Makefile
make dev-install

🚀 Quick Start

Create Your First Workflow in 3 Steps

Step 1: Define a Routine

from routilux import Routine

class DataProcessor(Routine):
    def __init__(self):
        super().__init__()
        # Define input slot
        self.input_slot = self.define_slot("input", handler=self.process_data)
        # Define output event
        self.output_event = self.define_event("output", ["result"])

    def process_data(self, data=None, **kwargs):
        # Flow is automatically detected from routine context
        result = f"Processed: {data}"
        self._stats["processed_count"] = self._stats.get("processed_count", 0) + 1
        self.emit("output", result=result)  # No need to pass flow!

Step 2: Create and Connect a Flow

from routilux import Flow

flow = Flow(flow_id="my_workflow")

processor1 = DataProcessor()
processor2 = DataProcessor()

id1 = flow.add_routine(processor1, "processor1")
id2 = flow.add_routine(processor2, "processor2")

# Connect: processor1's output → processor2's input
flow.connect(id1, "output", id2, "input")

Step 3: Execute

job_state = flow.execute(id1, entry_params={"data": "Hello, Routilux!"})
print(job_state.status)  # "completed"
print(processor1.stats())  # {"processed_count": 1}

🎉 Done! You've created your first workflow.

💡 Key Features

🔄 Event Queue Architecture

Routines communicate through events and slots using a unified event queue pattern:

# Multiple routines can listen to the same event
flow.connect(processor1, "output", processor2, "input")
flow.connect(processor1, "output", processor3, "input")  # Fan-out

# Multiple events can feed into the same slot
flow.connect(processor1, "output", aggregator, "input")
flow.connect(processor2, "output", aggregator, "input")  # Fan-in

# emit() is non-blocking - returns immediately after enqueuing tasks
# Flow is automatically detected from routine context
self.emit("output", data="value")  # No flow parameter needed!

🎛️ Flexible State Management

Track everything automatically:

# Access routine state
stats = routine.stats()  # {"processed_count": 42, "errors": 0}

# Track execution history
history = job_state.get_execution_history()

# Performance metrics
perf = flow.execution_tracker.get_routine_performance("processor1")

🛡️ Built-in Error Handling

Choose the right strategy for your use case:

from routilux import ErrorHandler, ErrorStrategy

# Stop on error (default)
flow.set_error_handler(ErrorHandler(ErrorStrategy.STOP))

# Continue and log errors
flow.set_error_handler(ErrorHandler(ErrorStrategy.CONTINUE))

# Retry with exponential backoff
flow.set_error_handler(ErrorHandler(
    ErrorStrategy.RETRY,
    max_retries=3,
    retry_delay=1.0,
    backoff_multiplier=2.0
))

⚡ Unified Execution Model

Both sequential and concurrent modes use the same event queue mechanism:

# Sequential mode (default): max_workers=1
flow = Flow()  # Sequential by default

# Concurrent mode: max_workers>1
flow.set_execution_strategy("concurrent", max_workers=4)

# Tasks are processed fairly in queue order
# Long chains don't block shorter ones
job_state = flow.execute(entry_routine_id)
flow.wait_for_completion()  # Wait for async tasks

💾 Persistence & Recovery

Save and resume workflows:

# Save workflow state
job_state.save("workflow_state.json")

# Later, resume from saved state
saved_state = JobState.load("workflow_state.json")
flow.resume(saved_state)
