We’ll cover installation, basic usage, and advanced workflows, helping you integrate Claude Code into your development process.

Prerequisites

Before getting started, ensure you have the following:

• Node.js 18.x
• Python 3.11+
• A Claude API key

Installation and Setup

1. Installation: Use npm install -g claude-code or the official OS installer.
2. Authentication: Run claude-code login and securely store your credentials.
3. Project Scaffolding: Create a workspace using claude-code init my-claude-project. This generates a sample configuration file.

Generating Code with Claude Code

Let’s create a simple Express app:

1. claude-code generate server --framework nodejs
2. Run the app using node server.js or npm start.
3. Refine your code using Claude Code’s in-editor prompts.

claude Code works seamlessly within various IDEs and terminals, supporting agent-based workflows across your entire codebase. Spotify, for instance, utilizes Claude Code across various teams—from finance to design to legal.

IDE Integration (VS Code)

The VS Code extension offers streamlined workflow. Install the extension, then use the command palette action “Claude Code: Scaffold API” to rapidly generate a REST API skeleton. Choose your preferred framework (e.g., Express for Node.js) and let Claude Code generate the necessary routes, controllers, and basic tests.

The generated scaffold includes:

• package.json: Project metadata and dependencies
• app.js: Express app bootstrapping and configuration
• routes/api.js: API endpoint definitions
• controllers/user.js: User-related business logic
• tests (Jest): Basic test suite

After installation (npm install), run the test suite using npm test. Adapt the generated code to match your specific data models and validation rules.

Terminal-First Workflow

For a terminal-centric approach:

1. Authenticate: claude-code login --api-key
2. Initialize: claude-code init my-project --template nodejs-api
3. Generate Controller: claude-code generate controller 'User' --methods getPostPutDelete

Troubleshooting

Common Issues and Solutions

• API Key Issues: Check your CLAUDE_API_KEY environment variable or re-authenticate using claude-code login.
• Rate Limits: Implement exponential backoff and local caching.
• Large Repositories: Use workspaces, pruning, and artifacts to manage context.
• Unresponsive Extension: Update the extension, reconnect, and check network settings.
