Description

This command detects and starts the appropriate development environments for your Mega project. By default, if both environments are detected, it starts both the Foundry/Anvil local blockchain and the Next.js frontend development server. The command automatically:
  • Detects Foundry and Next.js projects in the current directory or subdirectories
  • Starts Anvil with appropriate configurations for local blockchain development
  • Determines and uses the right package manager (npm, yarn, or pnpm) for the frontend
  • Provides convenient output with contract addresses and private keys

​
Examples

​
Start both environments

​
Start only the Foundry/Anvil local blockchain

​
Start only the Next.js frontend

​
Notes

  • Press Ctrl+C to stop the development servers
  • For cleaner logs, consider running the environments in separate terminals
  • The Anvil blockchain runs on port 8545 by default
  • The Next.js server typically runs on port 3000
  • init - Create a new Mega project
  • compile - Compile contracts before development
  • deploy - Deploy contracts to your development environment
