Celo Composer

Celo Composer is a TypeScript command-line tool that generates customizable starter projects for decentralized applications on Celo. It offers several app templates and optional wallet and smart-contract integrations, using a Next.js, TypeScript and Tailwind CSS stack organized with Turborepo and PNPM workspaces.

Understand the project

Practical overview

When it fits

Use it at the start of a Celo dApp project when you want to choose a template and integrations through CLI prompts or command-line options, then continue developing the generated code.

Who it is for

  • Developers starting a Celo dApp project who want a generated codebase rather than a hosted app builder.
  • Teams comparing starter structures for a basic web app, Farcaster Miniapp, Minipay app, AI chat app or x402 paid API.

Documented uses

  • Scaffold a Celo dApp project with a selected app template.
  • Choose whether to include RainbowKit or Thirdweb wallet integration.
  • Choose Hardhat or Foundry contract tooling, or skip contract setup.
  • Generate a monorepo structure with a Next.js web app and optional contracts app.
Before you choose

Requirements & limits

The CLI can be run through npx without a global installation. It requires Node.js 18.0.0 or later and PNPM, npm or Yarn. The repository specifies the MIT license.

  • The default setup selects the basic template, RainbowKit and Hardhat; prompts or flags can change these choices.
  • The template list includes both standard app scaffolds and specialized options such as x402, which requires a facilitator API key.
  • The generated stack includes Next.js, TypeScript, Tailwind CSS, shadcn/ui, Turborepo and PNPM workspaces.

Check current requirements in the official documentation. Source-based guidance does not mean OpenViST has run or independently tested this project.

Source-based practical guide

Generate a Celo dApp starter project

Create a starter codebase with a chosen template, wallet provider and contract framework.

Before you start

  • Node.js 18.0.0 or later
  • PNPM (recommended), npm or Yarn

Steps

  1. Run the command below.

    Documented command
    npx @celo/celo-composer@latest create my-celo-app

  2. In the interactive prompts, choose a template, wallet provider and smart-contract framework.

  3. After generation, enter the project directory; if dependency installation was skipped, run pnpm install.

  4. Start the development server with pnpm dev.

Expected outcome

A generated Celo app project with the selected integrations and a documented command for starting its development server.

Guide limitations

  • The default selections are a basic app, RainbowKit and Hardhat; --yes skips prompts and uses defaults.
  • The x402 template requires a facilitator API key, and its setup instructions are in the generated X402_SETUP.md.
