My favourite setup for writing Solidity smart contracts.
- Hardhat: compile and run the smart contracts on a local development network
- TypeChain: generate TypeScript types for smart contracts
- Ethers: renowned Ethereum library and wallet implementation
- Waffle: tooling for writing comprehensive smart contract tests
- Solhint: linter
- Solcover code coverage
- Prettier Plugin Solidity: code formatter
This is a GitHub template, which means you can reuse it as many times as you want. You can do that by clicking the "Use this template" button at the top of the page.
Before running any command, make sure to install dependencies:
$ yarn install
Compile the smart contracts with Hardhat:
$ yarn compile
Compile the smart contracts and generate TypeChain artifacts:
$ yarn typechain
Lint the Solidity code:
$ yarn lint:sol
Lint the TypeScript code:
$ yarn lint:ts
Run the Mocha tests:
$ yarn test
Generate the code coverage report:
$ yarn coverage
See the gas usage per unit test and average gas per method call:
$ REPORT_GAS=true yarn test
Delete the smart contract artifacts, the coverage reports and the Hardhat cache:
$ yarn clean
If you use VSCode, you can enjoy syntax highlighting for your Solidity code via the vscode-solidity extension. The recommended approach to set the compiler version is to add the following fields to your VSCode user settings:
{
"solidity.compileUsingRemoteVersion": "v0.8.3+commit.8d00100c",
"solidity.defaultCompiler": "remote"
}
Where of course v0.8.3+commit.8d00100c
can be replaced with any other version.
