### Memory Management - Conversation History
VoltAgent's memory system is fully TypeScript-compatible. You can start with zero-config or customize as needed:
```typescript
// Zero-config: Automatically creates .voltagent/memory.db file
const agent = new Agent({
name: "Memory Assistant",
instructions: "Assistant that remembers previous conversations",
llm: new VercelAIProvider(),
model: openai("gpt-4o"),
// Uses LibSQLStorage automatically if memory not specified
});
// First conversation
await agent.generateText("My name is John and I love pizza", {
userId: "user-123",
conversationId: "chat-1",
});
// Next conversation - will remember the previous one
const response = await agent.generateText("What's my favorite food?", {
userId: "user-123",
conversationId: "chat-1",
});
// "Based on our previous conversation, you love pizza!"
```
You can also use custom memory providers:
```typescript
import { LibSQLStorage, PostgreSQLStorage, InMemoryStorage } from "@voltagent/core";
// PostgreSQL for production
const prodAgent = new Agent({
// ... other config
memory: new PostgreSQLStorage({
connectionString: process.env.DATABASE_URL,
}),
});
// In-memory for testing
const testAgent = new Agent({
// ... other config
memory: new InMemoryStorage(),
});
```
## Quick Start Experience
Getting started with the framework is kept simple:
<Tabs>
<TabItem value="npm" label="npm" default>
```bash
npm create voltagent-app@latest my-ai-app
```
</TabItem>
<TabItem value="yarn" label="yarn">
```bash
yarn create voltagent-app my-ai-app
```
</TabItem>
<TabItem value="pnpm" label="pnpm">
```bash
pnpm create voltagent-app my-ai-app
```
</TabItem>
</Tabs>
The CLI guides you through the setup process:
1. **Project name** selection
2. **AI Provider** choice (OpenAI, Anthropic, Google, Groq, etc.)
3. **API Key** setup (optional)
4. **Package manager** selection
5. **IDE configuration**
After setup is complete:
```bash
cd my-ai-app
npm run dev
```
You'll see the VoltAgent server startup message in your terminal:
