⚒️Foundry Notes

What is Foundry good for?

  • Deploying contracts and interacting with those contracts

  • Running tests where everything is simulated

What's it bad at?

  • Listening for events on a live blockchain

  • Loops and timing scripts

Installation

Install Foundry
curl -L https://foundry.paradigm.xyz | bash

Initialize New Project

forge init <PROJECT_NAME>

Install Dependencies

  • The command forge install is used to install dependencies, such as libraries or other smart contracts that a project may need.

forge install OpenZeppelin/openzeppelin-contracts@v4.9.3 --no-commit

  • By default, when you install a dependency using forge install, Foundry will automatically create a new Git commit that includes the changes to your project (such as modifications to the foundry.toml file and the addition of the OpenZeppelin contract files in your project directory).

  • The --no-commit flag modifies this behavior. When you use this flag, Foundry will still install the OpenZeppelin contracts, but it will not automatically create a new Git commit for these changes. This means you have to manually commit the changes to your Git repository if you wish to do so.

  • The use of --no-commit gives you more control over your Git history and commit messages, which can be useful in certain workflows or for maintaining a clean project history.

Upgrade Foundry

  • foundryup updates foundry, but for some reason the command might not be available on the command line, so run the installation script again, then call it.

curl -L https://foundry.paradigm.xyz | bash
foundryup
