Redis + LangGraph.js Workshop

A hands-on workshop for building agentic AI applications using Redis and LangGraph.js. Build a news aggregator that fetches articles from RSS feeds, summarizes them, extracts named entities, generates embeddings, and stores everything in Redis. Then search, chat, and generate news briefs — all powered by AI.

What You'll Learn

• Ingestion workflows — Fetch RSS feeds, summarize articles, extract named entities, generate embeddings, and store everything in Redis
• Hybrid search — Combine vector similarity with structured filtering using Redis Search
• Tool-enabled RAG — Build a chatbot that retrieves and reasons over news articles
• Agent memory — Give your agent short-term and long-term memory with Redis Agent Memory Server

Tech Stack

• LangGraph.js — Workflow orchestration for AI agents
• Redis — Data storage with vector search and structured filtering
• Redis Agent Memory Server — Short and long-term memory for agents
• Svelte 5 — Modern reactive frontend
• Express — Node.js API server
• OpenAI — LLM and embedding models

Prerequisites

• Docker Desktop — For running the workbench and all services
• OpenAI API key — For LLM and embedding models

Getting Started

1. Clone the repo:

   git clone git@github.com:redis-developer/ai-news-agent-lang-graph-js-redis-workshop.git
   cd ai-news-agent-workshop

2. Copy the sample environment file and add your OpenAI API key:

   cp .env.sample .env

   Then edit .env and replace sk-proj-your-openai-key with your actual key.

3. Start the workbench:

   ./start.sh

4. Open http://localhost in your browser.

The workbench provides everything you need in a single browser tab:

Panel	Description
Instructions	Step-by-step workshop guide (sidebar)
Code	VS Code editor for writing code
App	The news agent application
Terminal	Shared terminal running the dev server
Redis Insight	Browse and inspect your Redis data

Stopping the Workbench

docker compose down

To also remove stored data (Redis, Redis Insight, VS Code settings):

docker compose down -v

Talk Abstracts

The abstracts/ folder contains two versions of the talk abstract:

• CONFERENCE-ABSTRACT.md — A version for developer conferences
• CORPORATE-ABSTRACT.md — A version for corporate/enterprise events
