Cursor AI Crash Course: boost Your Productivity with AI-Powered Coding

Introduction

Welcome back to the channel! Today, we're diving into an exciting tool known as Cursor AI, an AI-first code editor designed to revolutionize your coding experience. Whether you're a beginner or a seasoned developer, this tool is engineered to save you time and increase your productivity. In this crash course, we will build a complete application using Cursor AI. Instead of forming a definitive opinion on its usefulness, let’s experience it firsthand. Let's get started!

Introduction to Cursor AI

Cursor AI is an AI-powered integrated development environment (IDE) that seamlessly integrates AI assistance into your coding workflow. It functions like your AI-powered coding partner and offers a familiar interface for users of Visual Studio Code, enhanced with AI capabilities.

Key features of Cursor AI include:

• AI Chat: Understands your codebase and answers your queries effectively.
• Multi-line Suggestions: Provides suggestions across multiple lines of code.
• Smart Code Rewrites: Helps in refining your code.
• Natural Language Navigation: Allows you to navigate through your codebase using simple, natural language.

For developers looking for a faster and more intuitive coding experience, Cursor AI is a game-changer.

Setting Up Your Environment

Before diving into coding, make sure you've installed the Cursor AI IDE. The installation is straightforward—simply hit the "download for free" button. Once installed, let’s create a Next.js project.

Open your terminal, navigate to the desired project directory, and run the following command:

npx create-next-app@latest

Confirm that you have a stable version of Node.js installed and follow the prompts to set up a new project named cursor-ai-crash-course, selecting TypeScript, ESLint, and Tailwind CSS.

After the install completes, navigate into your project directory:

cd cursor-ai-crash-course

Now open the project in the Cursor IDE by executing:

cursor

Upon initial setup, if prompted, complete the login process. Press Ctrl + Shift + P to access Cursor settings, where you can manage your AI and editor preferences.

Exploring Cursor AI Features

Cursor's Tab Feature

The Tab feature helps make edits in your current file, allowing for multi-line modifications and suggesting actions based on recent changes. To demonstrate, let’s create a Todo application:

1. In the src folder, create a components directory and a file named TodoApp.tsx.
2. Start coding! As you type, suggestions will appear. For example, typing import will prompt suggestions to import React.

You can accept a suggestion by pressing Tab. Monitor your token usage as free users get a limited number of suggestions per month.

Using the Chat Feature

Cursor chat allows you to inquire about specific problems in your codebase. By pressing Ctrl + L, you can open the chat window. Select your desired models and ask for assistance with code-related queries. For instance, if you need help implementing an editing function, provide the appropriate code context, and the AI will generate the relevant code snippet along with an explanation.

Documentations and Web Searches

You can use external documentation to aid your coding. By adding relevant URLs to the documentation section in Cursor, the AI can provide suggestions based on that documentation.

Additionally, the web search feature allows you to find up-to-date information about coding practices without leaving the IDE.

The Composer Feature

One of the standout features of Cursor AI is the Composer, which allows for multi-file code generation for complex projects. With the Composer, you can issue commands to split components or even create full applications from given specifications, streamlining the development process significantly.

Simply press Ctrl + I to invoke the Composer and give it your instructions for generating code and structure.

Building a Complete Application

During the course, we successfully built a Todo application and then transitioned to create a small e-commerce website. The process showcased how Cursor AI can handle code generation tasks effectively—saving time and eliminating mundane boilerplate work.

With the ability to both generate new code and intelligently suggest modifications, Cursor AI proved to be a powerful ally in coding.

Conclusion

We explored various features of Cursor AI, from tab features and intelligent code suggestions to AI chat integration and web search capabilities. The Composer feature, in particular, stands out as a major enhancement for developers, allowing for quick multi-file code generation.

By using Cursor AI, we managed to create a fully functional e-commerce website with minimal effort, thanks to the AI’s suggestions and support.
