10 Generative AI Coding Extensions in VS Code You Must Explore

Introduction

Hey there, Coding ninja! What coding-related tasks do you have planned for the day? Before you dive further into this blog, I want you to think about all your coding-related woes—better list those down.

Done? – Let’s get started Now!

Imagine being a software developer in the 2000s. The entire coding process required many manual interventions. From adding documentation and comments to debugging to version control, the process was cumbersome and laborious! Moving to the 2010s, integrated development environments(IDEs) such as Eclipse, VSCode, and IntelliJ IDEA added many code-friendly features like helpful plugins, competent code assistance, and integration with version control systems.

Now, jumping right into the present, Generative AI-powered coding extensions offer to liberate developers from the shackles of their routine tasks, leaving space for creativity and problem-solving. These GenAI-powered development extensions can do a lot more than generate code. They can help create ideas, fix code, provide context-aware suggestions, explain code in simple language, automate documentation, etc. Integrated within our coding playgrounds or IDEs, these GenAI-powered tools are a perfect assistant for any coding endeavor.

A survey conducted in 2023 found that VS Code remains the most popular IDE among software developers worldwide.

This blog will explore some of the popular VS Code-based Generative AI extensions for coding.

Overview

• Understand what AI-based coding extensions are for software development and explore their key features.
• Evaluate the importance of AI extensions for software development.
• Learn how to integrate an AI coding extension in VS Code.
• Compare some of the best AI extensions for software development.
• Comprehend the factors involved while choosing an AI coding extension.

Integrated development Environments (IDE) like VS Code are used for various code development activities. From software developers and web developers to data scientists, everyone uses IDEs to support their coding requirements at different stages of the software development cycle. While the basic requirements of all coding tasks are relatively the same, there are some custom needs, too. To cater to specific or custom requirements, IDEs offer extensions that are add-ons or plugins to the existing framework. These can be paid or free, and the power to add or remove them lies solely in the user’s hands. This way, while an IDE infrastructure is the same for all, each user can make it unique by adding extensions per their requirements.

Why Should All Developers Be Using Gen AI-Based Coding Extensions?

A survey was conducted by Stack Overflow in May in which 65,000 developers participated to answer several questions about coding, working, and AI. According to it, 76% of the respondents accepted using Gen AI coding tools in their development process – a staggering 70% increase from 2023!

Gen AI Coding extensions are add-ons or plugins incorporated into IDE or integrated development environments. These extensions or code editors use Generative AI to enhance coding practices. Machine learning-based AI coding assistants have been around for quite some time, helping coders with tasks like code completion, syntax correction, debugging, etc. These large language-powered Gen AI coding assistants are a leap forward! These extensions include a range of complex tasks like code generation, completion, refactoring, automated testing, documentation generation, code reviews, etc.

Gen AI-based coding extensions can significantly increase the efficiency of software developers and the caliber of their work. With these extensions, developers can achieve:

• Enhanced Efficiency: AI-based coding extensions provide real-time code completions and suggestions, which can significantly accelerate the coding process. This minimizes the time spent inputting and referencing function parameters or syntax.
• Automated Code Reviews: GenAI extensions can examine code in real-time and give immediate input on performance enhancements, possible security flaws, and best practices.
• Learning and Upskilling: Generative AI-driven coding extensions provide inline documentation and usage examples for developers learning new programming languages or frameworks. This feature shortens the learning curve for developers by making it easier for them to comprehend unfamiliar code.
• Personalization: State-of-the-art coding extensions can recognize a developer’s unique coding style and make suitable changes. Such tools also offer tailored code completions and recommendations that adhere to team or project-specific standards.

Getting Started With GenAI Coding Extensions On VS Code

VS Code is a local IDE running directly on your computer. We need to install suitable extensions to integrate Generative AI into VS Code. Let’s see how that can be done.

Head to Extension’s Marketplace

Within VS code, many coding extensions are available in its extensions marketplace. You can access the extensions marketplace by clicking the square icon on the left sidebar. Alternatively, you can directly press CTRL+Shift+X on Windows/Linux or CMD+Shift+X on macOS. This would open the extensions marketplace directly in VS Code.

Search the extension

In the extensions view, you can type the extension name you wish to install and press Enter to get the required results.

Install

From the results, click to read the details regarding the extensions. Finally, hit “install” to add the extension to your VS Code studio.

It’s simple, right? Also, when multiple extensions are installed in your Studio, you can turn them on or off as and when required. This allows your IDE to run faster and clutter-free.

Quick Tip: Watch for updates or bug fixes to ensure you work with the latest features. VS Code will notify you about them.

Key Features of GenAI Extensions in VS Code

Now that we have understood how to install an extension in VS Code Studio, let’s quickly run through some of their key features. Most of the Gen AI extensions offer:

1. Code Autocompletion: These extensions automatically complete symbols as the programmer types, minimizing code writing effort and reducing coding errors. They utilize the context and the current coding environment to suggest variable names, functions, or keywords.
2. Chat with Code: With these extensions, users can interact with the coding extension using natural language. This is useful for asking questions about the codebase, receiving guidance, or executing commands within the IDE.
3. Code Generation: These extensions generate code snippets based on specific parameters or requirements. This can accelerate development by providing templates that programmers can refine and adapt.
4. Code Explanation: These extensions provide detailed explanations of code segments, helping developers understand complex logic or unfamiliar code. This is especially useful for educational purposes or when working in large teams.
5. Unit Test Generation: Developers can use these extensions to create unit tests for applications, ensuring that new changes or additions do not break existing functionality. This supports test-driven development (TDD) practices.
6. Find and Fix Bugs: These extensions can help scan the code to identify errors or bugs before runtime. This can include syntax errors, logical errors, or potential code inefficiencies. Additionally, they can offer tips for error corrections.
7. Refactor: These extensions help improve code structure without changing its external behavior. This is key in maintaining clean, efficient, and readable codebases.
