Source-based practical guide
Start the application locally for development
Run a local development instance of the Evm.codes web application.
Before you start
- Node.js 24 or later
- pnpm
- A clone of the Evm.codes repository
Steps
Clone the duneanalytics/evm.codes repository.
Install project dependencies with pnpm install.
If using the optional contract viewer, specify APIKEY_ETHERSCAN in .env.local.
Start the development server with pnpm dev and open http://localhost:3000.
Expected outcome
The development application is served locally at http://localhost:3000.
