Getting Started
Installation
npm install mem0ai openai zod
Environment Setup
Save your Mem0 and OpenAI API keys in a.env file:
MEM0_API_KEY=your_mem0_api_key
OPENAI_API_KEY=your_openai_api_key
Configuration
const USER_ID = "sample-user";
const openAIClient = new OpenAI();
const mem0Client = new MemoryClient({ apiKey: process.env.MEM0_API_KEY });
Adding Memories
Store user preferences, past interactions, or any relevant information:async function addUserPreferences() {
const mem0Client = new MemoryClient({ apiKey: process.env.MEM0_API_KEY });
const userPreferences = "I Love BMW, Audi and Porsche. I Hate Mercedes. I love Red cars and Maroon cars. I have a budget of 120K to 150K USD. I like Audi the most.";
await mem0Client.add([{
role: "user",
content: userPreferences,
}], { userId: "sample-user" });
}
await addUserPreferences();
{
"message": "Memory processing has been queued for background execution",
"status": "PENDING",
"event_id": "9f8c2b1a-4e7d-4c3a-9b21-1a2b3c4d5e6f"
}
Retrieving Memories
Search for relevant memories based on the current user input:const relevantMemories = await mem0Client.search(userInput, { filters: { user_id: USER_ID } });
Structured Responses with Zod
Define structured response schemas to get consistent output formats:// Define the schema for a car recommendation
const CarSchema = z.object({
car_name: z.string(),
car_price: z.string(),
car_url: z.string(),
car_image: z.string(),
car_description: z.string(),
});
// Schema for a list of car recommendations
const Cars = z.object({
cars: z.array(CarSchema),
});
// Create a function tool based on the schema
const carRecommendationTool = zodResponsesFunction({
name: "carRecommendations",
parameters: Cars
});
// Use the tool in your OpenAI request
const response = await openAIClient.responses.create({
model: "gpt-5-mini",
tools: [{ type: "web_search_preview" }, carRecommendationTool],
input: `${getMemoryString(relevantMemories)}\n${userInput}`,
});
Using Web Search
Combine memory with web search for up-to-date recommendations:const response = await openAIClient.responses.create({
model: "gpt-5-mini",
tools: [{ type: "web_search_preview" }, carRecommendationTool],
input: `${getMemoryString(relevantMemories)}\n${userInput}`,
});
