How to Build Full-Stack Apps Using Cursor

In this workshop, I’ll guide participants through a process for building full-stack applications using Cursor. We’ll cover setting up Cursor workflows, including rules, commands, and custom modes, to streamline development. We will use Cursor to draft PRDs, database schema, etc and a simple SOW. We’ll turn notes into actionable checklists to guide the build, connecting the front end, API, and database.

Additionally, we’ll create workflows for debugging, testing, reviewing, and fixing the app while reducing hallucinations with precise prompts. The session will also include a security review workflow and techniques for applying prompts to achieve a modern UI design. Attendees will leave with a functioning app on their machine and a reusable development process.

Pragmatic 101 on Custom JS Tooling for Your Project

Let’s demystify the secrets of modern JavaScript tooling. In this workshop, you will learn how linters, compilers, and code transforms work. You will take your first steps building your own developer tools, writing an ESLint rule, a compiler plugin, and a code transformation. Learn these skills to help your team and deepen your understanding of computer languages.

Workshop Plan:

1. A preview of how ASTs can be used
2. A brief walkthrough of how compilers work
3. An intro to working with an AST
4. The secret to making thousands of changes in seconds
5. How to apply this skill

Build a MCP (Model Context Protocol) in Node.js

Model Context Protocol (MCP) introduces a structured approach to LLM context management that addresses limitations in traditional prompting methods. In this workshop, you'll learn about the Model Context Protocol, its architecture, and how to build and use and MCP with Node.js

Table of Contents:

• What Is the Model Context Protocol?
• Types of MCPs (Stdio, SSE, HTTP Streaming)
• Understanding Tools, Resources, and Prompts
• Building an MCP with the Official TypeScript SDK in Node.js
• Deploying the MCP to the Cloud (Heroku)
• Integrating the MCP with Your Favorite AI Tool (Claude Desktop, Cursor, Windsurf, VS Code Copilot)
• Security Considerations and Best Practices

Interactive Debugging and Control in Node.js With REPL

You probably have faced a situation where you needed to debug something particular in your application. Something in a specific condition. These kinds of situations tend to be poorly handled by us developers.

A common approach is adding a bunch of logs, deploying the code, and waiting for the logs to return. This is a very slow process and can be very frustrating.

It would be much better if you could just get into the environment, while running, execute some code, and see the results. This is where the node:repl module comes in. It allows you to create a Read-Eval-Print Loop (REPL) in your Node.js application.

Inspired by Ruby on Rails, which has a very useful console, I implemented a console in the application I was working on. It was a game changer. Now, we have a way more effective debugging/experimentation process. My team fell in love with it. Now, it's part of the app, as it always has been.

Another good thing is that it was not hard to implement. The node:repl module gives everything. We just need to ensure the application is properly bootstrapped to use the REPL module.
