Bare-Bones Setup for Claude Code (Developer Quick Start)

Bare-Bones Setup for Claude Code (Developer Quick Start)

This guide is the minimum setup required for developers to start using Claude Code in a real project. The goal is simple: get Claude working in your development environment without installing a full stack of tools first. Claude can help install missing dependencies when needed.

1. What You Need (Minimum Requirements)

Before starting, make sure you have the following:

• Claude Professional or Team License (required for Claude Code access)

• Visual Studio Code installed

• Basic command line access (Terminal / PowerShell / Mac Terminal)

• Internet access for dependency downloads

That’s it.

You do NOT need to preinstall:

• Python

• Java

• Node

• React

• Build tools

Claude can help install missing dependencies when the project requires them.

2. Install Visual Studio Code

If you don’t already have it:

1. Download from

   
   

   https://code.visualstudio.com

2. Install using the default options.

3. Launch Visual Studio Code.

VS Code will serve as the primary editor and terminal environment.

3. Install Claude Code

Claude Code runs from the command line and integrates with your development workflow.

Open a terminal inside VS Code:

Terminal → New Terminal

Then run Claude:

claude

If Claude Code is installed correctly, the CLI will start and allow you to interact with Claude directly from your project folder.

4. Authenticate Your Claude License

The first time you run Claude Code, you will be prompted to authenticate.

Sign in using your Claude Professional or Team account.

Once authenticated, Claude will be able to:

• Read project files

• Generate code

• Run commands

• Help install dependencies

5. Start in a Project Folder

Claude works best when launched inside a project directory.

Example:

mkdir demo-app

cd demo-app

claude

Claude will now have context of your workspace.

6. Example Demo: Create a React App

You can immediately start building with Claude.

Example prompt:

Create a simple React application with a homepage and navigation.

Claude will typically:

1. Detect that Node or React tools may be missing

2. Recommend installing them

3. Provide the commands needed to set up the environment

4. Generate the application structure

Developers can follow the suggested commands directly.

7. Working with Java Projects

VS Code can also be used for Java development.

If a project requires Java:

Claude may recommend installing:

• Java JDK

• Maven or Gradle

Claude will provide the commands needed when required.

There is no need to preinstall Java unless the project requires it.

8. Recommended VS Code Extensions (Optional)

These are helpful but not required.

Common extensions:

• Java Extension Pack

• ESLint

• Prettier

• GitLens

Claude can recommend extensions as needed.

9. Development Workflow

Typical workflow:

1. Open VS Code

2. Open a project folder

3. Launch the terminal

4. Run:

claude

5. Ask Claude to:

   
   

   • generate code

   • create new components

   • explain architecture

   • run commands

   • help install dependencies

6. 
   

Claude becomes your AI development partner directly inside your workspace.

10. Key Principle

This setup intentionally keeps things simple.

Developers should:

• start with minimal tooling

• let Claude assist with environment setup

• focus on building and learning the codebase

The goal is to reduce setup friction and let developers start delivering value immediately.

Summary

Minimum setup:

1. Claude Professional License

2. Visual Studio Code

3. Command line terminal

Then simply:

open project

run claude

start building

Everything else can be installed only when the project requires it. 🚀
