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.
Everything I hit while converting from Pages Router to App Router — migration strategy, Server Component gotchas, data fetching rewrites, and honest before/after performance numbers.
Monorepos eventually hit a build time wall. Here's how Turborepo's task graph and caching solve the problem, shown through a real Next.js monorepo setup.
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.
