In the intricate realm of blockchain development, setting up a network can sometimes feel like assembling a complex puzzle. Fablo simplifies this process by supporting Hyperledger Fabric networks easily and efficiently. In this blog, we will guide you through the installation, basic usage, and management of Fablo.

Getting Started with Installation

To begin your journey with Fablo, the first step is to install it. Fablo is available as a single shell script that utilizes Docker images to create the network configuration. Here are two options for installation:

• Globally Install Fablo:

  sudo curl -Lf https://github.com/hyperledger-labs/fablo/releases/download/2.0.0/fablo.sh -o /usr/local/bin/fablo
  sudo chmod +x /usr/local/bin/fablo

• Install Fablo for a Single Project:

  curl -Lf https://github.com/hyperledger-labs/fablo/releases/download/2.0.0/fablo.sh -o .fablo
  chmod +x .fablo

Creating a Local Hyperledger Fabric Network

Once Fablo is installed, you can create your local Hyperledger Fabric network with Node.js chaincode and a REST API client. Simply execute the following command:

.fablo init node rest
.fablo up

This command sets up the entire network within minutes. You can monitor the nodes by using docker ps or docker stats commands.

Basic Usage Commands

Fablo offers various commands to manage your network effectively. Here are some essential commands:

• Starting the Network:

  .fablo up pathtofablo-config.json

• Stopping the Network:

  .fablo down

• Resetting the Network:

  .fablo reset

Managing the Network

With Fablo, you have a plethora of management options at your disposal:

• Init:

  .fablo init [node] [rest] [dev]

  This command helps to create a simple network configuration file.

• Generate:

  .fablo generate [pathtofablo-config.json/yaml]

  Generates network configuration files in the specified directory.

• Snapshot and Restore:

  .fablo snapshot target-snapshot-path

  Utilize this command to backup your network state, which is crucial for future use.

Troubleshooting

While Fablo simplifies many processes, you may encounter some hurdles along the way. Here are some troubleshooting tips:

• If you experience issues with the Docker containers not starting, ensure that Docker is installed and running properly.
• Check your Fablo configuration files for any syntax errors or misconfigurations. You can use the .fablo validate command to verify your configuration.
• If the REST API client is not working, ensure that it is enabled in your Fablo configuration.

Workings Behind the Code: An Analogy

Imagine building a city (your network) in a large empty lot (your local machine). Fablo acts like an architect and a contractor rolled into one, guiding you on how to set up utilities (Docker containers), lay out streets (network configurations), and manage buildings (smart contracts or chaincodes). By using simple commands, you can quickly visualize and control the development of your city without needing to lay every brick by hand.

Understanding the Fablo Configuration

The Fablo configuration file, typically in JSON or YAML format, holds the key to your Hyperledger Fabric network’s topology. It can be thought of as a blueprint for your city, detailing the layout of organizations, channels, and chaincodes.
