Tools

• Foundry for unit testing
• Hardhat for JS integration tests & deployment
• hardhat-sol-bundler for declarative deployments and upgrades
• linters, code formatter, pre-commit and pre-push hooks
• Makefile & Docker dev container for convenient and safe development
• Custom github action and quality gate workflow for flexible CI strategy implementation

Requirements

• Git
  • You'll know you've done it right if you can run git --version
• Node.js
• Optional (Development). Foundry / Foundryup
  • This will install forge, cast, and anvil
  • You can test you've installed them right by running forge --version and get an output like: forge 0.2.0 (f016135 2022-07-04T00:15:02.930499Z)
  • To get the latest of each, just run foundryup
• Optional (Virtualization). Docker
  • You'll need to run docker if you want to use dev container and safely play with smartcontracts & scripts

note: For windows os you'll need to install make. For instance via choco: sh choco install make

Installation

Development:

make

Deployment:

make install-ci

Modify .env file

Configuration

• All commands/aliases are declared in the Makefile.
• use forge as solidity formatter in your IDE settings
  • For VS it's recommended to use Juan Blanco Plugin and have the next sittings.json

{
  "solidity.formatter": "forge",
  "solidity.packageDefaultDependenciesContractsDirectory": "src",
  "solidity.packageDefaultDependenciesDirectory": ["node_modules", "lib"],
  "solidity.remappings": [
    "@std=lib/forge-std/src/",
    "forge-std/=lib/forge-std/src/",
    "@openzeppelin/=node_modules/@openzeppelin/",
    "src=src/"
  ],
  "solidity.defaultCompiler": "localNodeModule",
  "[solidity]": {
    "editor.defaultFormatter": "JuanBlanco.solidity"
  }
