Viem Lecture

This project uses viem for TypeScript/JavaScript Ethereum interactions.

Getting started

npm install

Writing scripts

Put your scripts in the scripts/ directory.

To run a script:

# If you have a newer version of Node
node scripts/your-script.ts

# TypeScript (using tsx)
npx tsx scripts/your-script.ts

Environment variables

To read variables from a .env file when running a script:

node --env-file=.env scripts/your-script.ts

The script will have access to all variables defined in .env via process.env.VARIABLE_NAME.

Prompts

To read user input from the console, you can use the prompts library:

const { name } = await prompts([{
    name: 'name',
    type: 'text',
    message: 'Enter your name: '
}])
