Quickstart

To test out deploying a dApp on Celo, we recommend using Celo Composer, which allows you to quickly build, deploy, and iterate on decentralized applications using Celo. It provides a number of frameworks, examples, templates and Celo specific functionality to help you get started with your next dApp.

Prerequisites​

  • Node (v20 or higher)
  • Git (v2.38 or higher)

How to use Celo Composer​

The easiest way to start with Celo Composer is using @celo/celo-composer. This CLI tool lets you quickly start building dApps on Celo for multiple frameworks, including React (and rainbowkit). To get started, just run the following command, and follow the steps:

npx @celo/celo-composer@latest create

🚀 Your starter project has been successfully created!

Before you start the project, please follow these steps:

1. Rename the file:
   packages/react-app/.env.template
   to
   packages/react-app/.env

2. Open the newly renamed .env file and add all the required environment variables.

Once you've done that, you're all set to start your project!

Run the following commands from the packages/react-app folder to start the project:

   yarn install
   yarn dev

If you prefer npm, you can run:

   npm install
   npm run dev

Thank you for using Celo Composer! If you have any questions or need further assistance, please refer to the README or reach out to our team.
