In the evolving world of blockchain technology, crafting smart contracts efficiently is paramount. The Foundry Template provides a robust framework that simplifies the development of Solidity smart contracts with sensible defaults. In this guide, we’ll explore how to set up and utilize this template to make your smart contract development journey smoother.

Getting Started

To kick-off your project with the Foundry Template, you have two options: use GitHub to generate a repository or set it up manually on your machine.

Option 1: Use GitHub

• Click the Use this template button at the top of the repository page.

Option 2: Manual Setup

sh
$ mkdir my-project
$ cd my-project
$ forge init --template PaulRBerg/foundry-template
$ bun install # install Solhint, Prettier, and other Node.js dependencies

Features of the Template

This template incorporates several powerful frameworks and libraries. Below is an overview:

• Forge: Compile, test, fuzz, format, and deploy smart contracts.
• Forge Std: A collection of utilities and contracts for testing.
• Prettier: A code formatter for all non-Solidity files.
• Solhint: A linter specifically for Solidity code.

Integration with VSCode

While the template is IDE agnostic, it works fabulously with VSCode, especially when using the Nomic Foundation’s Solidity extension. For more on integrating Foundry projects in VSCode, refer to the VSCode Integration Guide.

Installing Dependencies

This template adopts Node.js packages instead of traditional git submodules to manage dependencies efficiently. Here’s how to install them:

1. Install the required dependency using your preferred package manager, for example:

   sh
       bun install dependency-name
       

2. To install from GitHub, use:

   sh
       bun install github:username/repo-name
       

3. Add a remapping in remappings.txt:

   sh
       dependency-name=node_modules/dependency-name
       

Writing Tests

Writing tests is critical for ensuring your smart contract behaves as expected. Start by importing the Test framework from forge-std and inheriting it in your test contract. This template includes an example contract at .test/Foo.t.sol.

Common Commands

Here’s a collection of frequently used commands for ease of use:

• Build:

  sh
      forge build
      

• Clean:

  sh
      forge clean
      

• Compile:

  sh
      forge build
      

• Lint:

  sh
      bun run lint
      

• Test:

  sh
      forge test
      

Troubleshooting

If you run into issues while setting up or using the Foundry template, consider the following troubleshooting steps:

• Ensure all dependencies are installed correctly by running bun install.
• Check your environment configuration and ensure you have the correct Node.js version.
• If your tests are failing, make sure your Solidity code compiles correctly and meets all necessary standards.
• For any persistent issues, consult the Foundry Book or the specific documentation for any of the libraries used.
