Follow these steps to install the Flow CLI on macOS, Linux, and Windows.
Create your first project
The Flow CLI is Flow’s primary development and testing environment, similar to Hardhat and Foundry for developers familiar with writing in Solidity. With the Flow CLI super commands, initiating your new project becomes effortless. Execute the
flow setup command and make a selection from a variety of accessible scaffolds.
_19> flow setup hello-world --scaffold_19_19🔨 General Scaffolds_19 Empty Cadence Project - Empty project containing only basic folder structure and flow.json configuration._19 Simple Cadence Project - Scaffold contains required folder structure as well as some example Cadence code._19 Cadence NFT Project - Scaffold contains the ExampleNFT sample NFT contract._19 Hybrid Custody Project - Starter for exploring & implementing Hybrid Custody._19_19💻 Web Scaffolds_19 FCL Web Dapp - Simple TypeScript web application using next.js, FCL, and Cadence._19_19📱 Mobile Scaffolds_19 Swift iOS simple example - iOS example demonstrating usage of FCL and Flow interactions._19 Android simple example - Android example demonstrating usage of FCL and Flow interactions._19 FCL React Native Mobile Dapp - React Native (Expo) mobile dapp example demonstrating FCL and Flow interactions._19_19🏀 Unity Scaffolds_19 Simple Unity - Simple example demonstrating how to interact with the Flow network using Unity SDK._19 Mobile Unity Game - Example words game built on Flow using the Unity SDK.
After you have created your new project you can proceed writing contracts and by running
command the CLI will make sure they are deployed to the Flow emulator for you. Flow emulator is
a simplified version of Flow network you can use locally to develop.
So proceed by starting the emulator:
_10> flow emulator_10``_10_10After creating your new project you are ready to start writing contracts. The Flow emulator is a simplified local simulation of the Flow network. Running the dev command in the CLI ensures that the contracts are deployed to the Flow emulator for you._10_10And then the flow dev:
