AI Memory: Stop Building Stateless Agents thumbnail

AI Memory: Stop Building Stateless Agents

The video demonstrates agentic memory in TanStack AI, contrasting episodic (per-chat) memory with long-term memory that retains user preferences across conversations, using a sushi example. It then outlines how to plug in multiple memory engines (Hindsight, Mem0, Honcho, or a DIY local store) through a memory middleware, and explains recall/retain workflows and tool support to enable memory across chats and interactions.

Stop Getting Roasted in PR Review (CodeRabbit, Locally) thumbnail

Stop Getting Roasted in PR Review (CodeRabbit, Locally)

The speaker discusses leveraging CodeRabbit to improve pre-PR code reviews and reduce risk in TanStack projects, while acknowledging personal weaknesses in writing specs and evaluating diffs. They demonstrate multiple integration paths (CLI, Claude Code, and Cursor) and show how AI-assisted reviews can be run during development, not just before PRs, including AI-driven fixes and feedback. The video ends with appreciation for CodeRabbit sponsorship and a call to try the tools.

Prompt to Dashboard in One AI Tool Call thumbnail

Prompt to Dashboard in One AI Tool Call

The video demonstrates how TanStack AI Code Mode connects to a database (Netlify Database) and builds dynamic reports by combining TypeScript-generated logic with injected tools. It walks through setting up Drizzle Studio, migrations, seeding data, and the Code Mode integration to generate reports and a dynamic UI, plus how the tooling is shared between Code Mode and standard LLM usage.

WebMCP Is A Free AI In Your App thumbnail

WebMCP Is A Free AI In Your App

The video showcases how WebMCP can augment existing web app architectures (MVC patterns with stores like Redux or TanStack) by connecting them to a WebMCP-enabled UI. It walks through a practical Multiboard/OpenSCAD workflow (parametric builders, WASM for mesh generation, ThreeJS rendering) and demonstrates AI-assisted parameter control and validation to drive updates in real time. The author highlights easy integration, tooling registration, and the potential to extend existing systems with AI-driven, configurable parameters, with the code available on GitHub.

Partial Page Caching Using React Server Components thumbnail

Partial Page Caching Using React Server Components

TanStack Start positions React Server Components as a specialized, not universal, tool. The video walks through a CDN-backed content-site example, showing how RSCs fetch flight data via server functions, enable region-specific caching, and load interactive components on demand to keep bundles lean, arguing RSCs shine for targeted scenarios like trending/news widgets rather than a one-size-fits-all solution.

5 Ways To SSR/RSC on TanStack Start thumbnail

5 Ways To SSR/RSC on TanStack Start

The video surveys five data-loading approaches in TanStack Start alongside React Server Components (CSR, SSR, data-only SSR, RSC, and composite components), and clarifies that React has long supported server rendering in an isomorphic model. Through a Pokemon API example, it shows how each variant fetches data via loaders, contrasts client-side hydration with server-rendered markup, and discusses architectural patterns like page shells and composite component slots.

TanStack Start SSR: 3 Reasons To Love It thumbnail

TanStack Start SSR: 3 Reasons To Love It

The video introduces three reasons to love Tanstack Start’s server-side rendering (SSR) and demonstrates how easy it is to implement SSR with a default, practical setup. It walks through real examples—loading data with loaders, using server functions, and the data-only mode—showing how SSR can preload data, render on the server, and still smoothly support client-side navigation. The presenter emphasizes that SSR can be toggleable, strongly typed, and especially beneficial for dashboards, while stressing that the approach remains lightweight and developer-friendly.
