dev

Start development environments for Mega projects

mega dev

The dev command starts development environments for your Mega blockchain project.

Usage

mega dev [options]

Options

Option	Description
--foundry	Start only the Foundry/Anvil local blockchain
--frontend	Start only the Next.js frontend

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

mega dev

Start only the Foundry/Anvil local blockchain

mega dev --foundry

Start only the Next.js frontend

mega dev --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
