Welcome to the world of Ethereum blockchain development! If you’re looking to streamline your smart contract deployment and testing processes, you’ve landed in the right place. In this guide, we will explore how to set up Clevis for Ethereum blockchain orchestration, testing, and DApp scaffolding. Let’s dive in!

Requirements

Before you start your adventure, you need a local Ethereum blockchain to develop against. If you haven’t decided on your preferred method yet, we recommend using Ganache from Truffle for its ease of use. You can easily set it up by following these steps:

• Install Ganache CLI globally by running:

npm install -g ganache-cli

• Then run Ganache CLI by typing:

ganache-cli

Start a New Project with Clevis

Once you have your local blockchain running, it’s time to initiate a Clevis project. Navigate to your empty project directory and execute the following command:

npx clevis init

This command will prompt you with a few questions and proceed to create a new Clevis-powered project in your current directory.

Using Clevis

By default, the Clevis setup does not install globally, but you can do so by running:

npm install -g clevis

If you prefer to use Clevis without global installation, you can access it in your local node modules directory:

node_modules/clevis/bin.js

For convenience, consider adding an alias in your ~/.profile or ~/.bashrc file:

alias clevis=./node_modules/clevis/bin.js

After setting this up, you can invoke Clevis commands using just the letter ‘c’. For example:

clevis randomhex 100

Alternatively, you can add Clevis as an npm script in your package.json:

"scripts": {
    "clevis": "clevis"
}

This allows you to use Clevis with:

npm run clevis randomhex 100

Optional: Docker Setup

If you face challenges with the setup instructions above, Docker provides a convenient solution. To pull a repeatable environment, run:

docker run -ti --rm --name clevis -p 3000:3000 -p 8545:8545 -v ~your-dapp-directory:dapp austingriffith/clevis:latest

Troubleshooting Tips

While setting up Clevis, you may run into some issues, particularly with Web3 dependencies. Here are a few common problems and their solutions:

• If you encounter errors around permissions, like:

  gyp ERR! stack Error: EACCES: permission denied

  Try running:

  sudo npm install --unsafe-perm -g clevis@latest

• For a “Cannot find module web3” error, go to your Clevis directory and run:

npm link

• In case of issues related to version mismatches, make sure to clear out your node_modules and regenerate your environment:

  rm -rf node_modules package-lock.json

  Followed by:

  npx clevis init; npm install
