Hey there! If you're into blockchain development, particularly with Solidity, and love using Foundry, you're in the right place. Today, I'm going to walk you through setting up Visual Studio Code (VSCode) to work seamlessly with Solidity and Foundry. Let's dive in!
Step 1: Install the VSCode Solidity Extension
First things first, to get Solidity support in VSCode, you need to install the VSCode Solidity extension. This extension is a must-have for any Solidity developer using VSCode.
Step 2: Setting Up Remappings
Remappings are crucial in ensuring that your project's dependencies are correctly resolved. Here's how to set them up:
Using
remappings.txt
: Place your remappings in aremappings.txt
file. This is especially useful if you're transitioning fromfoundry.toml
.From
foundry.toml
: Already have remappings infoundry.toml
? Just copy them over toremappings.txt
.Autogenerated Remappings: If you rely on Foundry's autogenerated remappings, simply run
forge remappings > remappings.txt
to create yourremappings.txt
file.
Step 3: Configure Dependencies
To help the Solidity extension find your project's dependencies, add these settings to your .vscode/settings.json
:
{
"solidity.packageDefaultDependenciesContractsDirectory": "src",
"solidity.packageDefaultDependenciesDirectory": "lib"
}
Here, src
is where your source code lives, and lib
is your dependency directory.
Step 4: Formatter Setup
Good code formatting is non-negotiable. To enable Foundry's built-in formatter and automatically format your code on save, add these settings to your .vscode/settings.json
:
{
"editor.formatOnSave": true,
"[solidity]": {
"editor.defaultFormatter": "JuanBlanco.solidity"
},
"solidity.formatter": "forge",
}
For more on configuring the formatter, check out the Formatter reference.
Step 5: Specify solc
Version
Consistency in compiler versions between your IDE and Foundry is key. Specify your Solidity compiler version in .vscode/settings.json
:
"solidity.compileUsingRemoteVersion": "v0.8.23",
And align Foundry with this version in foundry.toml
:
solc = "0.8.23"
And there you have it! A straightforward guide to setting up your VSCode for a smooth Solidity development experience with Foundry. Remember, a well-set-up environment can make your coding experience much more enjoyable and efficient. Happy coding!
