Is Biome or ESLint better for JavaScript linting?

ESLint is better for teams needing the largest ecosystem of rules and plugins (React, TypeScript, accessibility) and maximum rule customization. Biome is better for teams wanting 10-100x faster linting AND formatting in a single tool with zero configuration — it replaces both ESLint and Prettier with one Rust-based tool.

What do Biome and ESLint users complain about most?

Based on our analysis of thousands of user reviews, Biome users most frequently mention the learning curve and occasional performance issues. ESLint users tend to cite pricing concerns and limitations on lower-tier plans. Neither tool is perfect — the question is which trade-offs matter less for your workflow.

เลือก Biome if you want one Rust-based tool that replaces both ESLint AND Prettier — 10-100x faster, zero config, and ideal for new projects. เลือก ESLintif you need the massive plugin ecosystem (React hooks, JSX accessibility, custom rules) or have ซับซ้อน existing configs. Biome ชนะ 4-2 overall, but ESLint's ecosystem depth remains unmatched for ซับซ้อน projects.

ฟีเจอร์ ภาพรวม

Biome (formerly Rome) is a Rust-based toolchain that replaces ESLint + Prettier in a single binary. The speed difference is dramatic — a codebase that takes 2 minutes to lint with ESLint may take 5 seconds with Biome. The zero-config approach means you can run "biome check ." on any project immediately without configuring anything. First-class TypeScript support is built in, no plugins required. Biome is increasingly adopted by companies like Ubisoft, Shopify, and Discord.

Installation & Setup

Step	Command	Notes
Install	npm install --save-dev @biomejs/biome	Single dependency
Init	npx biome init	Creates biome.json with defaults
Run	npx biome check .	Lint + format in one command

Who Should เลือก Biome?

Teams starting new JavaScript/TypeScript projects
CI pipelines where lint speed matters (saves minutes per build)
Developers tired of ESLint + Prettier configuration conflicts
Projects that want one tool instead of multiple dependencies

Best Ecosystem & Plugin Customization

ฟีเจอร์ ภาพรวม

ESLint is the established JavaScript linting standard with the largest plugin ecosystem in existence. eslint-plugin-react-hooks enforces React Hook rules, eslint-plugin-jsx-a11y catches accessibility issues, and @typescript-eslint ให้ deep TypeScript analysis. Pre-built configs like Airbnb, Standard, and Google give ทีม instant code style enforcement. Over 30 million weekly npm downloads make it the most-used JS tool by far.

Common Configuration Stack

Package	Purpose	Weekly Downloads
eslint	Core linter	30M+
@typescript-eslint	TypeScript support	15M+
eslint-plugin-react	React-specific rules	12M+

Who Should เลือก ESLint?

Projects needing React Hook rules (eslint-plugin-react-hooks)
Teams with ซับซ้อน existing ESLint configurations
Accessibility-focused projects using eslint-plugin-jsx-a11y
Organizations requiring custom lint rules not in Biome

ESLint

ใครควรเลือกอะไร?

→ เลือก Biome if:

You're starting a new project and want one tool instead of ESLint + Prettier with dramatically faster CI checks. Biome's zero-config defaults cover most JavaScript/TypeScript best practices. The speed improvement is especially noticeable in CI pipelines and pre-commit hooks.

→ เลือก ESLint if:

You need React-specific rules (eslint-plugin-react-hooks, jsx-a11y), have a ซับซ้อน existing ESLint configuration, or require custom rules Biome doesn't yet support. ESLint's plugin ecosystem with thousands of rules remains unmatched for accessibility and framework-specific requirements.

→ ควรหลีกเลี่ยงทั้งคู่ถ้า:

You're writing a small script or prototype — linting adds overhead you don't need. For personal projects under 500 lines, TypeScript's built-in compiler checks may be sufficient.

Also ข้อเสียidered

We evaluated several other tools in this category before focusing on Biome vs ESLint. Here are the runners-up and why they didn't make our final comparison:

VS Code— The most popular code editor with vast extensions, but can become slow with many plugins.

JetBrains IDEs— top-tier language-specific features, but heavy on system resources and expensive.

Neovim— Ultimate keyboard-driven editor for power users, but steep learning curve.

คำถามที่พบบ่อย

Is Biome faster than ESLint?

Yes — dramatically. Biome is written in Rust and is 10-100x faster than ESLint + Prettier combined. CI pipelines that took minutes with ESLint can complete in seconds with Biome. The tradeoff is fewer rules and no React-specific plugin support yet.

ความเห็นบรรณาธิการ

I switched my last three projects to Biome and haven't looked back. The CI time savings alone justified it — our lint step went from 90 seconds to 3 seconds. But I still keep ESLint on our React projects for the hooks rules. My advice: use Biome everywhere you can, ESLint where you must.
