Top-Ten-Code-Extensions-of-2021

Visual Studio Code is one of the most widely used code editors in the developer community. One of the reasons for VS Code’s popularity is its many extensions that speed up the development process.

In this guide, we’ll explore the 10 VS Code extensions every web developer should know in 2021. These tools are designed to improve the developer experience and make your job easier in various ways.

We’ll cover the following VS Code extensions:

  1. Auto Rename Tag
  2. Bracket Pair Colorizer
  3. Snippets
  4. Better Comments
  5. Markdown All in One
  6. Icons
  7. Prettier
  8. Import Cost
  9. Profile Switcher
  10. GitLens

1. Auto Rename Tag

Auto Rename Tag is a super useful VS Code extension for web developers. As the names suggest, Auto Rename Tag renames the second tag as the first one is updated and vice versa:

Auto-Rename-Tag-Gif

You will find this extension helpful not only with HTML, but also with React because of JSX.

React-JSX-Auto-Rename-Tag

In the above example there is only text inside the tags, but in a real application, there can be nested tags and elements, making manual updates difficult and tedious.

2. Bracket Pair Colorizer

Bracket Pair Colorizer is an extension that matches corresponding brackets with the same color. Having nested components, functions, objects, etc., in a file, can become confusing with multiple parentheses, brackets, etc.

Bracket-Pair-Colorizer-Example

We made a custom demo for .
No really. Click here to check it out.

For example, consider the following code snippet:

Bracket-Pair-Colorizer-Code-Snippet

At first glance, it’s quite hard to differentiate between different code blocks in the code, but the Bracket Pair Colorizer extension colors the corresponding parenthesis and brackets for easy navigation and accessibility.

3. Snippets

Snippets are the best way to save time and increase your productivity. This is not a single extension but a collection of extensions with various snippets for different programming languages.

Below are some popular code snippets extensions:

For example, it can be quite tedious to repeat the syntax for functional components in React every time you create a new component. Using the ES7 React/Redux/GraphQL/React-Native snippets extension, you can use the shorthand rfc for functional components and hit enter.

React-Redux-GraphQL-Extension

4. Better Comments

Better Comments is designed to help you write more human-friendly comments in your code.

Clear, digestible comments are beneficial not only for someone going through your code but also for you. It’s quite common for developers to get lost in their own code when visiting it after some time. Having descriptive comments can save a lot of time for you and your team.

With the Better Comments VS Code extension, you can categorize your annotations into alerts, queries, to-dos, highlights, etc.

You can use either of the following characters after double forward slash (//):

  • * for highlighted text
  • ! for errors and warnings
  • ? for queries and questions
  • // for strikethrough
  • TODO for to-dos

5. Markdown All in One

Markdown All in One is a single extension that takes care of all your markdown needs, such as auto-preview, shortcuts, autocomplete, etc.

Since its release in 2004, Markdown has become one of the most popular and preferred markup languages. Technical writers worldwide widely use Markdown for articles, blogs, documentation, etc., because of its lightweight simplicity and cross-platform usage. Its popularity has given rise to other variants of Markdown, such as GitHub Flavored Markdown, MDX, etc.

For example, to bold some text in Markdown, you can select that text and use the shortcut Ctrl + B to increase your productivity.

6. Icons

Having descriptive icons can help you differentiate between files and folders. Icons also make development more fun.

Here is a comparison between two VS Code tabs. One has icons, the other does not.

There are many icons extension that you can choose from. Popular icon collections include:

7. Prettier

Prettier is an opinionated code formatter. With more than 38.5k stars on GitHub, it’s one of the most popular code formatters available. Having consistent formatting and styling across your code can save a lot of time, especially when collaborating with other developers.

Consider the following code block:

Prettier-Demo-Code-Example

You may notice a handful of formatting issues with this code, including:

  • A mix of single and double-quotes
  • Irregular use of semicolons (;)
  • Improper indentation of the console statement on line 6

Here’s how Prettier would format and fix the above code:

This extension supports Prettier plugins when you’re using a locally resolved version of Prettier.
You can configure this extension further to suit your formatting needs and even trigger it with autosave.

8. Import Cost

Import Cost is an extension that shows you an estimated size of the import package in your code. When working on a project, it’s important not to compromise the user experience by importing heft packages. One way to avoid this is to keep track of the size of additional dependencies in your code.

Import-Cost-Extension-Example

When the import is too large, Import Cost warns you by displaying the size in red. You can configure what size should be considered small, medium, or large.

9. Profile Switcher

Profile Switcher enables you to switch between and set up multiple profiles in your VS Code with various configurations and settings.

This extension is especially useful for content creators such as technical bloggers, YouTubers, etc. Instead of changing your settings/configurations every time you need to show your VS Code screen, you can set up a profile required settings.

Here’s how to switch between two profiles: Default and Content Creation.

GitLens is an open-source extension for Visual Studio Code created, developed, and maintained by Eric Amodio. It combines the capabilities of Git with VS Code.

One of the best features of this extension is the ability to visualize code authorship via Git blame annotations and code lens.

Below is a screenshot from the React example docs of the Final Space API.

: Full visibility into your web apps

LogRocket is a frontend application monitoring solution that lets you replay problems as if they happened in your own browser. Instead of guessing why errors happen, or asking users for screenshots and log dumps, LogRocket lets you replay the session to quickly understand what went wrong. It works perfectly with any app, regardless of framework, and has plugins to log additional context from Redux, Vuex, and @ngrx/store.

In addition to logging Redux actions and state, LogRocket records console logs, JavaScript errors, stacktraces, network requests/responses with headers + bodies, browser metadata, and custom logs. It also instruments the DOM to record the HTML and CSS on the page, recreating pixel-perfect videos of even the most complex single-page apps.
