Tired of ESLint and Prettier config conflicts? Biome combines linting and formatting in one blazing-fast Rust-based tool.
Asking AI to 'make a login page' gives garbage. Structured prompts with context, constraints, and examples produce production-ready code.
Setting up a new Mac took 2 days. With dotfiles and automation scripts, it now takes 30 minutes to get a fully configured dev environment.
My Kanban board built with HTML5 Drag and Drop worked everywhere except Naver Whale. Browser gestures hijack native drag events. dnd-kit's Pointer Events architecture bypasses this entirely.
Tried to contribute to an open source project but gave up because there was no README. That's when I realized the true value of good docs.
What changed after starting to use Biome:
npm install --save-dev @biomejs/biome, biome init, done..eslintrc, .prettierrc, eslint-config-prettier entirely.Sure, ESLint + Prettier remains a powerful combination. Especially when complex rules or specific plugins are needed, ESLint is still necessary.
But for most projects—especially new ones—I'm convinced Biome is the better choice. Fast, simple, and sufficiently powerful.
If you're tired of configuration hell, it's worth trying. You might think "why didn't I use this sooner," just like I did.
# Getting started is this simple
npm install --save-dev @biomejs/biome
npx biome init
npx biome check --write .
Now let's focus on writing code. Biome will handle the linter and formatter battles for us.
