Shuffly is an open-source tool that allows you to build and run data pipelines, automate tasks, and integrate various systems. What sets Shuffly apart is its visual, low-code/no-code interface, making it accessible to both technical and non-technical users. This ingenious design allows you to focus on the logic of your workflows rather than getting bogged down in complex coding. It supports various data sources, including databases, APIs, and file systems, and offers a wide range of transformation functions. Shuffly simplifies the creation of ETL processes, data synchronization tasks, and automated responses to events, making it an invaluable asset for streamlining operations and improving data-driven decision-making.

Installation: Getting Started with Shuffly

Installing Shuffly is straightforward and can be accomplished in a few simple steps. The installation method may vary slightly depending on your operating system and desired configuration. Here are the common approaches:

1. Using Docker (Recommended)

Docker is the preferred method for installing Shuffly as it provides a consistent and isolated environment. This eliminates potential dependency conflicts and simplifies the setup process.

First, ensure you have Docker and Docker Compose installed on your system. If not, you can download and install them from the official Docker website.

Next, create a docker-compose.yml file with the following content:

version: "3.8"
services:
  shuffly:
    image: ghcr.io/fmeringdal/shuffly:latest
    ports:
      - "3000:3000" # Web UI
      - "8000:8000" # API
    volumes:
      - shuffly_data:/data

volumes:
  shuffly_data:

This configuration defines a service named “shuffly” that uses the latest Shuffly image from GitHub Container Registry. It maps port 3000 for the web UI and port 8000 for the API. It also creates a volume named “shuffly_data” to persist your data and configurations.

Navigate to the directory containing the docker-compose.yml file and run the following command:

docker-compose up -d

This command will download the Shuffly image and start the container in detached mode. You can then access the Shuffly web UI by navigating to http://localhost:3000 in your web browser.

2. Manual Installation (Less Common)

While Docker is recommended, you can also install Shuffly manually if you prefer. This usually involves cloning the Shuffly repository, installing dependencies, and configuring the application.

First, clone the Shuffly repository from GitHub:

git clone https://github.com/fmeringdal/shuffly.git
cd shuffly

Next, install the required dependencies. This step may vary depending on the specific dependencies of the version you are using. Consult the Shuffly documentation for the most up-to-date instructions. A common pattern involves using a package manager like npm or yarn:

npm install # or yarn install

After installing dependencies, you’ll likely need to configure the application. This typically involves setting up environment variables or modifying configuration files. Refer to the Shuffly documentation for detailed configuration instructions.

Finally, you can start the Shuffly application:

npm start # or yarn start

This will start the Shuffly server, and you can access the web UI by navigating to the specified address (usually http://localhost:3000).

Usage: Building and Running Workflows

Once Shuffly is installed and running, you can start building and executing workflows. The visual interface makes this process intuitive and straightforward. Here’s a step-by-step guide:

1. Accessing the Web UI

Open your web browser and navigate to the address where Shuffly is running (e.g., http://localhost:3000). You will be presented with the Shuffly dashboard.

2. Creating a New Workflow

Click on the “New Workflow” button to create a new workflow. You will be presented with a blank canvas where you can drag and drop components to build your workflow.

3. Adding Components

Shuffly provides a variety of components, including input sources, transformation functions, and output destinations. To add a component, simply drag it from the component library onto the canvas.

For example, let’s create a simple workflow that reads data from a CSV file, transforms it, and writes it to a database.

  1. Drag a “CSV Reader” component onto the canvas.
  2. Drag a “JSON Transformer” component onto the canvas.
  3. Drag a “Database Writer” component onto the canvas.

4. Configuring Components

Each component has its own set of configuration options. To configure a component, click on it to open the configuration panel.

CSV Reader Configuration:

{
  "file_path": "/path/to/your/data.csv",
  "delimiter": ",",
  "header": true
}

JSON Transformer Configuration:


// Example transformation: Convert all keys to uppercase
(data) => {
  const transformedData = {};
  for (const key in data) {
    if (data.hasOwnProperty(key)) {
      transformedData[key.toUpperCase()] = data[key];
    }
  }
  return transformedData;
}

Database Writer Configuration:

{
  "db_type": "postgres",
  "host": "localhost",
  "port": 5432,
  "database": "mydatabase",
  "user": "myuser",
  "password": "mypassword",
  "table": "mytable"
}

5. Connecting Components

Connect the components by dragging lines from the output of one component to the input of another. This defines the flow of data through the workflow.

6. Running the Workflow

Click the “Run” button to execute the workflow. Shuffly will execute the components in the defined order, transforming and transferring the data as specified.

7. Monitoring the Workflow

Shuffly provides real-time monitoring of the workflow execution. You can view the status of each component, inspect the data at each stage, and identify any errors that occur.

Tips & Best Practices

To maximize the effectiveness of Shuffly, consider the following tips and best practices:

  • Plan your workflows: Before you start building, take the time to plan out the logic and flow of your workflows. This will help you avoid unnecessary complexity and ensure that your workflows are efficient and effective.
  • Use modular components: Break down complex workflows into smaller, modular components. This makes it easier to understand, maintain, and debug your workflows.
  • Implement error handling: Implement robust error handling to gracefully handle unexpected errors. This prevents workflows from crashing and ensures data integrity.
  • Monitor performance: Regularly monitor the performance of your workflows to identify bottlenecks and optimize performance.
  • Document your workflows: Document your workflows thoroughly to make them easier to understand and maintain. This is especially important for complex workflows or when working in a team.
  • Version control: Use version control (e.g., Git) to track changes to your workflows and collaborate with others.

Troubleshooting & Common Issues

While Shuffly is designed to be user-friendly, you may encounter some issues during installation or usage. Here are some common problems and their solutions:

  • Docker Installation Issues: Ensure that Docker is properly installed and running on your system. Check the Docker logs for any errors.
  • Connectivity Problems: Verify that you can connect to the required data sources (e.g., databases, APIs). Check your network configuration and firewall settings.
  • Component Configuration Errors: Double-check the configuration of each component to ensure that it is correct. Pay attention to data types, file paths, and connection parameters.
  • Workflow Execution Errors: Examine the workflow execution logs to identify the source of the error. Look for error messages and stack traces.
  • Dependency Conflicts: If you are using a manual installation, ensure that all dependencies are properly installed and that there are no version conflicts.
