AI CLI Chat

A minimal command-line chatbot powered by Claude (Anthropic) with streaming responses and persistent conversation history.

Features

• Real-time streaming output — responses print token-by-token as they arrive
• Multi-turn conversation — full message history is maintained within a session
• Automatic retry — backs off and retries up to 3 times on API overload errors
• Simple loop — type a message, get a response, repeat until you type exit

Requirements

• Node.js 18+
• An Anthropic API key

Setup

npm install
export ANTHROPIC_API_KEY=your_api_key_here

Usage

node chat.mjs

🚀 AI Chat CLI — type "exit" to quit

You: Hello!

🤖 Claude: Hi! How can I help you today?

You: exit
Goodbye!

Type exit to end the session.

How it works

• Each user message is appended to a history array and sent to claude-sonnet-4-20250514 via the Anthropic SDK's streaming API.
• The assistant's full response is captured and appended to history, so the model has context for every follow-up message.
• On overloaded_error responses, the script waits 2 s, 4 s, then 6 s between retries before giving up.
