| title: "Mastra agents with memory sharing + Trigger.dev task orchestration" | ||
| sidebarTitle: "Mastra agents with memory" | ||

|
||
| ## Overview | ||
|
|
||
| Enter a city and an activity, and get a clothing recommendation generated for you based on today's weather. | ||
|
|
||
|  | ||
|
|
||
| By combining Mastra's persistent memory system and agent orchestration with Trigger.dev's durable task execution, retries and observability, you get production-ready AI workflows that survive failures, scale automatically, and maintain context across long-running operations. | ||
|
|
||
| ## Tech stack | ||
|
|
||
| - **[Node.js](https://nodejs.org)** runtime environment | ||
| - **[Mastra](https://mastra.ai)** for AI agent orchestration and memory management (Mastra is a Typescript framework for building AI agents, and uses Vercel's AI Agent SDK under the hood.) | ||
| - **[PostgreSQL](https://postgresql.org)** for persistent storage and memory sharing | ||
| - **[Trigger.dev](https://trigger.dev)** for task orchestration, batching, and observability | ||
| - **[OpenAI GPT-4](https://openai.com)** for natural language processing | ||
| - **[Open-Meteo API](https://open-meteo.com)** for weather data (no API key required) | ||
| - **[Zod](https://zod.dev)** for schema validation and type safety | ||

|
|
||
| ## Storage Architecture | ||
|
|
||
| This project uses a **centralized PostgreSQL storage** approach where a single database connection is shared across all Mastra agents. This prevents duplicate database connections and ensures efficient memory sharing between the weather analyst and clothing advisor agents. | ||
|
|
||
| ### Storage Configuration | ||
|
|
||
| The storage is configured once in the main Mastra instance (`src/mastra/index.ts`) and automatically inherited by all agent Memory instances. This eliminates the "duplicate database object" warning that can occur with multiple PostgreSQL connections. | ||
|
|
||
| The PostgreSQL storage works seamlessly in both local development and serverless environments with any PostgreSQL provider, such as: | ||
|
|
||
| - [Local PostgreSQL instance](https://postgresql.org) | ||
| - [Supabase](https://supabase.com) - Serverless PostgreSQL | ||
| - [Neon](https://neon.tech) - Serverless PostgreSQL | ||
| - [Railway](https://railway.app) - Simple PostgreSQL hosting | ||
| - [AWS RDS](https://aws.amazon.com/rds/postgresql/) - Managed PostgreSQL | ||
