Ignite

Ignite CLI

Ignite CLI is the all-in-one platform to build, launch, and maintain any crypto application on a sovereign and secured blockchain. It is a developer-friendly interface to the Cosmos SDK, the world's most widely-used blockchain application framework. Ignite CLI generates boilerplate code for you, so you can focus on writing business logic.

Quick start

Ignite CLI can be installed using popular package managers such as Homebrew and Snap, making it easy to stay up-to-date with the latest versions. These package manager installations are maintained regularly for both macOS and GNU/Linux. For those who prefer manual installation or need to set up a development environment, additional instructions are provided at the end of this section.

Installation

Install Ignite using Homebrew on macOS and GNU/Linux:

brew install ignite

Or using Snap on GNU/Linux:

snap install ignite --classic

Or manually using the following command:

curl https://get.ignite.com/cli! | bash
Troubleshoot

If Ignite doesn't automatically move to your /usr/local/bin directory, use the following command:

sudo mv ignite /usr/local/bin

If you encounter an error, you may need to create the /usr/local/bin directory and set the necessary permissions:

mkdir /usr/local/bin
sudo chown -R $(whoami) /usr/local/bin

To create and start a blockchain:

ignite scaffold chain mars

cd mars

ignite chain serve

The instructions for installing Ignite CLI manually and configuring your system are provided below.

Cosmos SDK compatibility

Blockchains created with Ignite CLI use the Cosmos SDK framework. To ensure the best possible experience, use the version of Ignite CLI that corresponds to the version of Cosmos SDK that your blockchain is built with. Unless noted otherwise, a row refers to a minor version and all associated patch versions.

Ignite Apps

Ignite Apps aims to extend the functionality of Ignite CLI, offering both official and community-contributed integrations. These integrations are designed to streamline development processes and offer valuable insights for blockchain app developers.

How to Install an Ignite App

ignite app install -g github.com/ignite/apps/[app-name]

The ignite app list command allows to list the plugins and their status, and to update a plugin if you need to get the latest version.

How to Create an App

Scaffold your Ignite app with one simple command:

ignite scaffold app path/to/your/app

Afterwards, install using:

ignite app install -g path/to/your/app

For more information, refer to Creating Ignite Apps.
