Table of Contents

This is my curated list of VS Code extensions that I have installed and its corresponding settings, fully synced on all of my machines. Each extensions has its own purpose and unique perks, I’ll explain it briefly for each item in this list.

I will list all the extensions complete with its name and url link to the marketplace. Another way to install all the extensions in this list quickly is to use a simple python script I made, available as a repository on my GitHub account with my extensions embedded with it.

Editor Enhancements

Built-in settings
"editor.suggest.snippetsPreventQuickSuggestions": false,

Code Spell Checker

Spell checking has helped me so much in naming my variables and writing my code. It has also helped me a lot when I’m writing for my posts in markdown so that I don’t misspell anything stupid, paired with Error Lens it makes a perfect combo for dev bloggers.


I only use this to format my html files, everything else uses Prettier.

"beautify.language": { "js": {}, "css": [], "html": ["htm", "html"] }, "[html]": { "editor.defaultFormatter": "HookyQR.beautify" },


From editorconfig.org, it helps maintain consistent coding styles for multiple developers across various editors and IDEs. A lot of editors should natively support this, but VS Code doesn’t, so this is where the plugin comes in. Below is my current goto config, will be updated frequently as I get used to it.

root = true [*] charset = utf-8 end_of_line = lf indent_size = 2 indent_style = tab trim_trailing_whitespace = true [*.md] indent_size = 4 indent_style = space [package.json] indent_style = space


Quickly add a .gitignore file that fetches its data from the GitHub mega repository consisting of multiple ignore files for various file extensions.


Makes everything related to Git more convenient and nice.

"gitlens.advanced.telemetry.enabled": false, "gitlens.codeLens.scopes": ["document", "containers"], "gitlens.mode.statusBar.enabled": false, "gitlens.recentChanges.highlight.locations": ["line", "gutter", "overview"], "gitlens.views.compare.enabled": false, "gitlens.views.fileHistory.location": "scm", "gitlens.views.lineHistory.enabled": false,

Image preview

Creates a small preview of the image linked in the sidebar right by the line number, helpful to know if the link in valid. Anything from relative paths to url will be displayed.

Prettier - Code formatter

My choice of code formatter, it supports a huge variety of languages.

"prettier.disableLanguages": ["html", "vue"], "vetur.format.defaultFormatter.css": "prettier", "vetur.format.defaultFormatter.js": "prettier",

Remote - WSL

The only extension made to connect VS Code and WSL natively by Microsoft.

Visual Studio IntelliCode

Still has some problems with Python built-in jedi, but it’s way too useful for other languages, especially JavaScript.

"vsintellicode.modify.editor.suggestSelection": "automaticallyOverrodeDefaultValue", "vsintellicode.python.completionsEnabled": true, // false if you want to use jedi

Editor Visuals


Supports .env files with syntax highlighting.

Error Lens

Super helpful extension that highlights the entire line where a diagnostic is generated with the message printed inline. Always makes any error stands out to quickly debug and fix it.


Really helpful and makes reading code easier with the different indentation color coded.

"indentRainbow.errorColor": "rgba(0,0,0,0)",

Material Icon Theme

My icon pack of choice.

Rainbow Brackets

Rainbow Brackets is an alternative to Bracket Pair Colorizer, it’s lightweight and doesn’t heat up the PC much. I read it somewhere that Bracket Pair Colorizer, even when idle sucks up much power, so I immediately changed it to Rainbow Brackets and noticed some improvements with it.

Rainbow CSV

Makes CSV much more easy to read while still being lightweight.

Language Specific




Python Indent

Python Indent makes it so when you enter into a new line, it corrects it for you automatically. Working with other languages is a breeze, you don’t need to worry about the indentation or spacing between it because the formatter will correct itself according to the curly brackets. But, we don’t have that in Python, and one indent difference is the difference between executing in the loop or after the loop.


A supplementary extension for those working with other file extensions that don’t necessarily have py in it but still relates to Python like .wsgi


Used to work with Kivy making cross-platform applications using Python and this has helped a lot with providing syntax highlighting, code snippets, and language server that provides diagnostics.

Java Properties

A simple syntax highlighter for .properties files.

Gradle Language Support

Add syntax highlighting and language support with autocomplete (Intellisense).

Web Development

Babel JavaScript

Used to have this when I was developing with React (JSX), it supports a lot of things in modern JS ecosystem like highlighting for React, GraphQL, and style-components (CSS-in-JS).

CSS Peek

Allow peeking CSS IDs and classes directly to the respective CSS file. Avoid having to manually search and debug for the selectors by yourself.


Pretty helpful for beginners to learn writing CSS firsthand. It provides information about their costs, what will be affected, and how it will affect it.


Integrates ESLint directly to VS Code whenever you have it install globally or locally.

HTML CSS Support

CSS support with class and ID attribute completion.

"css.lint.duplicateProperties": "error", "css.lint.compatibleVendorPrefixes": "warning", "css.lint.float": "error", "css.remoteStyleSheets": [],

Live Server

Quick server for plain HTML and vanilla JavaScript development.

"liveServer.settings.CustomBrowser": "firefox", "liveServer.settings.donotShowInfoMsg": true, "liveServer.settings.donotVerifyTags": true, "liveServer.settings.host": "localhost", "liveServer.settings.port": 0,

Import Cost

Display the size of the imported package inline after the import.

"importCost.bundleSizeDecoration": "both", "importCost.javascriptExtensions": ["\\.js?$", "\\.jsx?$"], "importCost.timeout": 60000,


This extension is to ensure that package.json is up to date and are not bloated by unused modules. Used with the extension below.

npm Intellisense

This indexes the package.json and node_modules folder to autocomplete import statements when importing or requiring modules.

REST Client

Allows you to send HTTP request and view the response in directly from the file editor. A lightweight and simple alternative for Postman.

"rest-client.enableTelemetry": false,


Typescript Lint support by Microsoft.

JS Framework Complementary


The official Svelte extension developed by the internal team is available and it’s amazing, I think it’s definitely not a question for anyone writing Svelte in VS Code.

"[svelte]": { "editor.defaultFormatter": "svelte.svelte-vscode" },

Svelte 3 Snippets

Using snippets are completely a subjective matter, it’s really your choice whether to use pre-made snippets, create your own, or just write it from scratch every time. At least for me, I quite enjoy having snippets to quickly type in my code.


Vue Snippets

Mobile Development


Dart language support and debugger.

"dart.debugExternalLibraries": false, "dart.debugSdkLibraries": false, "dart.previewFlutterUiGuides": true, "dart.previewFlutterUiGuidesCustomTracking": true, "[dart]": { "editor.rulers": [80], "editor.selectionHighlight": false, "editor.suggest.snippetsPreventQuickSuggestions": false, "editor.suggestSelection": "first", "editor.tabCompletion": "onlySnippets", "editor.wordBasedSuggestions": false },


A must-have for Flutter development.

Flutter Tree

Like emmet for Flutter.

Pubspec Assist

Easily add dependencies to your Dart / Flutter project.


Ascii Tree Generator

Quickly generates tree-like structure of directories and files with ascii. Pretty helpful when working with text-only to visualize something and we don’t need to exit the editor.

Instant Markdown

Instantly preview markdown inside the editor.

"instantmarkdown.autoOpenBrowser": false, "instantmarkdown.autoCloseServerAndBrowser": false,

Markdown All in One

Complete all in one markdown support.

"[markdown]": { "editor.defaultFormatter": "yzhang.markdown-all-in-one", "editor.lineHeight": 24, "editor.lineNumbers": "off", "editor.minimap.enabled": false, "editor.tabSize": 4, "editor.wordWrap": "wordWrapColumn", "editor.wordWrapColumn": 96, "editor.quickSuggestions": { "other": false, "comments": false, "strings": false }, "files.eol": "\n" },


Markdown linter for clean markdown writing.

"markdownlint.config": { "MD013": false, "MD025": false, "MD029": false, "MD033": false, "MD040": false, "MD041": false },


XML and YAML language support with syntax highlighting by Red Hat.
