@photon-ai/rapid

Toolkit for rapid AI and agent prototyping. Rapid gives you reusable building blocks so you can validate new agent architectures, memory systems, and workflows without rebuilding the interface layer every time.

Why Rapid

• Terminal-first developer experience for iterating on prompts, memory, and control flows.
• Composable modules exposed as ESM entry points; mix and match what you need.
• TypeScript-first API with strong types for chat messages, event handlers, and controller handles.

Installation

Install the package with your preferred manager (Node.js 18+):

npm install @photon-ai/rapid
# or
pnpm add @photon-ai/rapid
# or
bun add @photon-ai/rapid

Rapid expects a TypeScript toolchain (typescript@^5.9.3 as a peer dependency). If you are running in CommonJS, bundle or load with a compatible transpiler such as ts-node/register.

Module Catalog

This section will expand as new building blocks ship. Each module lives under an explicit export path so you can import only what you need.

Category	Module	Description	Status
Chat TUI	@photon-ai/rapid/cli-chat	Ink-powered terminal chat UI with message panel, input bar, and controller API.	Available

Usage Patterns

CLI Chat

Render the chat surface inside your CLI and connect it to your agent logic.

// demo.ts
import { renderChatUI } from "@photon-ai/rapid/cli-chat";

const delay = (ms: number) => new Promise((resolve) => setTimeout(resolve, ms));

const chat = renderChatUI();

chat.sendMessage("Welcome to Rapid! Type anything and I'll echo it back.");

chat.onInput(async (prompt) => {
    chat.sendMessage("Thinking...");
    await delay(500);
    chat.sendMessage(`Echo: ${prompt.toUpperCase()}`);
});

// Keep the Ink app alive. Press Ctrl+C to exit.
await new Promise(() => {});

Run the example with your preferred TypeScript runner:

ts-node demo.ts

Controller API snapshot

• renderChatUI() mounts the Ink application and returns an imperative controller.
• chat.onInput(handler) registers listeners for user-submitted prompts (supports async handlers).
• chat.sendMessage(content) streams assistant messages back into the UI in real time.

Developing New Modules

• Add modules under src/<module-name> and export them via package.json.
• Document each module with a short description and example import path in the catalog above.
• Keep runnable snippets in this README so users can copy-paste and tinker.

Repo Scripts

Rapid uses Bun for scripts and dependency management:

bun install        # install dependencies
bun run src/index.ts
