For most React projects, start with ESLint and Prettier—if the project uses them—and add other extensions only to address a specific need. VS Code already includes JavaScript debugging, IntelliSense, and code navigation, so a large extension pack is not a prerequisite for React development.
The list below is organized by purpose and project fit, not ranked: the available documentation does not establish an objective top 15 or compare these extensions in hands-on tests. Current versions and maintenance can change, so check each live Marketplace listing before installing.
Which extensions belong in a React developer’s core setup?
Begin with the tools your repository and team actually use. React’s editor setup guidance discusses ESLint and Prettier; neither extension substitutes for configuring those tools in the project.

ESLint
ESLint (dbaeumer.vscode-eslint) integrates ESLint diagnostics into VS Code. Install it when the repository is configured for ESLint, and ensure the project configuration includes the rules your team expects. React’s setup guidance specifically advises enabling the React Hooks rules. Installing the editor extension alone does not create or replace that configuration.
#1 Best Overall
Prettier – Code formatter
Prettier – Code formatter (esbenp.prettier-vscode) is useful when the project uses Prettier. React documents configuring format-on-save in VS Code. If ESLint formatting rules conflict with Prettier, separate formatting from linting rather than expecting both tools to apply competing rules.
What optional extensions fit particular workflows?
These additions are useful for specific languages, frameworks, repository habits, or testing setups. They are not requirements for React itself.
React and JavaScript snippets
ES7+ React/Redux/React-Native snippets (dsznajder.es7-react-js-snippets) provides typing shortcuts for people who find its templates convenient. A snippet is just a way to insert code faster; it is not a guarantee of best-practice structure. Microsoft also lists JavaScript (ES6) code snippets (xabikos.JavaScriptSnippets) as an option, while noting that VS Code already has built-in snippets. If you install a snippet pack, choose templates you will use rather than accumulating overlapping packs.

Tailwind CSS IntelliSense
Tailwind CSS IntelliSense (bradlc.vscode-tailwindcss) is relevant when the project uses Tailwind CSS. React does not require Tailwind; skip this extension for projects using another styling approach.
Git history and repository context
GitLens — Git supercharged (eamodio.gitlens) adds Git history and repository context in the editor. VS Code already includes source-control features, so consider GitLens when its added views suit your workflow rather than treating it as a baseline requirement.
More visible diagnostics
Error Lens (usernamehw.errorlens) makes diagnostics from language tools more visible in the editor. It presents reported diagnostics; it does not create a new linter or replace the tool that detects problems.
Jest test workflow
Jest (orta.vscode-jest) is an option for repositories that use Jest and want test workflow features in VS Code. Use it only if Jest is part of the project’s actual setup; a different test framework calls for a different choice.
npm import autocomplete
Microsoft also describes npm IntelliSense (christian-kohler.npm-intellisense) as a convenience for autocomplete of npm modules in import or require statements. Install it if that assistance fits your habits; it is not essential to a React setup.
How should you choose what to install?
- Follow the repository: use ESLint, Prettier, Tailwind CSS IntelliSense, or Jest support only when the project uses the corresponding tool.
- Avoid overlapping features: VS Code already has debugging, IntelliSense, code navigation, built-in snippets, and source-control features. Add an extension when its additional workflow is useful to you.
- Follow team conventions: share project-relevant recommendations with the team, but keep personal workflow preferences optional.
- Check the current listing: maintenance and versions can change. Review the publisher, README, changelog when available, and dependencies on the extension’s Marketplace details page.
How do you install and assess an extension safely?
VS Code’s Extension Marketplace documentation explains how to inspect, install, update, disable, and uninstall extensions. Extensions have the same permissions as VS Code itself, and VS Code prompts users to trust third-party publishers when installing. Confirm the publisher and extension ID before installation, then inspect the current listing and its details.

Install from the Marketplace
- Open the Extensions view in VS Code and search for the extension by name or exact identifier, such as
dbaeumer.vscode-eslint. - Open its details page. Check that the publisher and extension ID match the intended extension, and review its README, dependencies, and changelog when available.
- Select Install only if the extension fits your project and you trust its publisher. Respond to VS Code’s publisher-trust prompt with care.
- Use the Extensions view to update, disable, or uninstall it later if it is no longer needed.
Share recommendations with a project
For extensions that are genuinely useful to everyone working in a repository, VS Code supports workspace recommendations in .vscode/extensions.json. Teams can commit project-specific recommendations—for example, ESLint and Prettier where the project uses them—while leaving personal preferences out of the shared setup.
Does a React project need fifteen extensions?
No. The title’s number should not be read as a recommended installation count. React work can start with VS Code’s built-in JavaScript features, then add project-aligned linting and formatting integrations. Snippets, Tailwind support, Git history views, more visible diagnostics, test integration, or npm autocomplete are choices to make when they solve a real workflow need.
