Installation Options

There are multiple ways to install the Next.js and Vercel stack for Claude Code. Choose the approach that best fits your workflow:

Install Individual Components


# Install specific agent
npx claude-code-templates@latest --agent web-tools/nextjs-architecture-expert

# Install specific Next.js command
npx claude-code-templates@latest --command nextjs-vercel/nextjs-component-generator

# Install specific hook
npx claude-code-templates@latest --hook automation/vercel-auto-deploy

Components will be installed to:

  • 📁 .claude/commands/ - Command files (.md)
  • 📁 .claude/agents/ - Agent files (.md)
  • 📄 .claude/settings.json - Hook configurations with embedded logic

Agents and commands are installed as separate markdown files in their respective directories, while hooks are embedded directly into the .claude/settings.json file. Each hook contains its complete logic as an inline bash command within the JSON configuration.

Create Global Agents (Available Anywhere)

# Create global agents accessible from any project
npx claude-code-templates@latest --create-agent web-tools/nextjs-architecture-expert
npx claude-code-templates@latest --create-agent devops-infrastructure/vercel-deployment-specialist
npx claude-code-templates@latest --create-agent web-tools/react-performance-optimizer

# List all global agents
npx claude-code-templates@latest --list-agents

# Update global agents
npx claude-code-templates@latest --update-agent web-tools/nextjs-architecture-expert

# Remove global agents  
npx claude-code-templates@latest --remove-agent devops-infrastructure/vercel-deployment-specialist

Install Multiple Components at Once


# Install specific Next.js commands (comma-separated for multiple)
npx claude-code-templates@latest --command nextjs-vercel/nextjs-component-generator,nextjs-vercel/nextjs-bundle-analyzer,nextjs-vercel/nextjs-performance-audit
              

# Install complete Next.js + Vercel stack in one command
npx claude-code-templates@latest \
  --command nextjs-vercel/nextjs-component-generator,nextjs-vercel/nextjs-bundle-analyzer,nextjs-vercel/nextjs-performance-audit,nextjs-vercel/vercel-deploy-optimize,nextjs-vercel/vercel-edge-function,nextjs-vercel/vercel-env-sync \

  --setting statusline/vercel-deployment-monitor \
  --mcp deepgraph/deepgraph-nextjs

This will install:

  • ✓ 6 Next.js and Vercel commands
  • ✓ 3 specialized AI agents
  • ✓ 4 intelligent automation hooks
  • ✓ 1 Vercel status line monitor (only one can be active)
  • ✓ 1 DeepGraph MCP Integration

Where Components Are Installed

The installation creates a standard Claude Code structure with components organized as follows:

your-nextjs-project/
├── .claude/
│   ├── agents/
│   │       ├── nextjs-architecture-expert.md
│   │       ├── vercel-deployment-specialist.md
│   │       └── react-performance-optimizer.md
│   ├── commands/
│   │       ├── nextjs-component-generator.md
│   │       ├── nextjs-bundle-analyzer.md
│   │       ├── nextjs-performance-audit.md
│   │       ├── vercel-deploy-optimize.md
│   │       ├── vercel-edge-function.md
│   │       └── vercel-env-sync.md
│   └── settings.json (contains all hook configurations with embedded logic)
├── .mcp.json
└── src/ # Your Next.js application code

How Hook Installation Works

When you install a hook using the --hook flag, the CLI performs one key action:

  1. Configuration in settings.json: The hook configuration (including all the embedded code logic) is directly added to your .claude/settings.json file. The hook's entire logic is contained within the JSON as an inline bash command, not as separate script files.

For example, here is how the Vercel auto-deploy hook is registered in settings.json with its complete embedded logic:

{
  "hooks": {
    "PostToolUse": [
      {
        "matcher": "Write|Edit|MultiEdit",
        "hooks": [
          {
            "type": "command",
            "command": "bash -c 'input=$(cat); TOOL_NAME=$(echo \"$input\" | jq -r \".tool_name\"); FILE_PATH=$(echo \"$input\" | jq -r \".tool_input.file_path // empty\"); if [[ \"$FILE_PATH\" =~ \\.(js|jsx|ts|tsx)$ ]]; then echo \"🚀 Triggering Vercel deployment...\"; vercel --yes; fi'",
            "timeout": 120
          }
        ]
      }
    ]
  }
}

This configuration contains the complete hook logic embedded directly in the JSON, ensuring automated deployment workflows run seamlessly when code changes occur.

How MCP Integration Works

When you install an MCP (Model Context Protocol) integration, the command configures the connection to the MCP server in the .mcp.json file in your project's root directory. This file acts as a central registry for all MCP tools, allowing Claude Code to discover and use them.

Using the Next.js and Vercel Stack

Once installed, you can immediately start using the components in your Claude Code sessions:

Quick Start Commands

# Generate a new Next.js component
/nextjs-component-generator UserProfile components/ui

# Analyze Next.js bundle size
/nextjs-bundle-analyzer

# Audit Next.js performance
/nextjs-performance-audit

# Optimize Vercel deployment
/vercel-deploy-optimize

# Create Vercel edge function
/vercel-edge-function

AI Agents Integration

You can activate the specialized agents by directly asking for them in your prompt. Mentioning the agent's role or name is enough to have them handle your request with their specific expertise.

# Ask the agent to perform a task by mentioning its role
> As the Next.js Architecture Expert, can you review my app structure for best practices?

# Another example
> I need the Vercel Deployment Specialist to help me optimize my deployment strategy.

Automated Hooks

The hooks are triggered automatically by specific events within your Claude Code session. For example, a hook might run after you modify a file or use a specific tool. Once installed, they work in the background to automate tasks:

  • 🚀 Auto-deploy triggers after file modifications to initiate a new Vercel deployment.
  • 📊 Performance guard blocks deployments that exceed budgets
  • ✅ Code quality enforcer ensures Next.js best practices
  • 🔄 Environment sync keeps variables consistent
  • 📈 Health monitor tracks deployment success

Advanced Features

Status Line Integration

The stack includes three pre-built Vercel status line monitors that display real-time deployment information at the bottom of your Claude Code interface:

⚠️ Important: Only one statusline can be active at a time in Claude Code. Installing a new statusline will replace any existing one. You can switch between statuslines by installing different ones.

🔹 Vercel Deployment Monitor

Shows current build status, deployment URL, and time since last deployment with intuitive icons:

Install:

# Install basic deployment monitor
npx claude-code-templates@latest --setting statusline/vercel-deployment-monitor

Result:

▲ Vercel 🚀 ✅ READY | 🌐 my-app-xyz.vercel.app | ⏰ 5m ago | 📁 my-project

🔹 Vercel Error Alert System

Intelligent error monitoring with desktop notifications and building status tracking:

Install:

# Install error alert system with notifications
npx claude-code-templates@latest --setting statusline/vercel-error-alert-system

Result:

▲ Vercel 🚀 🚨 2 errors! | Building: 0 | 📁 my-project

🔹 Vercel Multi-Environment Status

Monitors production and preview environments simultaneously with color-coded indicators:

Install:

# Install multi-environment status monitor
npx claude-code-templates@latest --setting statusline/vercel-multi-env-status

Result:

                    ▲ Vercel 🚀 Prod:🟢 Prev:🟡 | 📁 my-project
