## Package Versions
**[vite](https://vite.dev)** — `v8.0.10`
A build tool and dev server for modern web projects. Starts instantly (no bundling in dev), uses native ES modules in the browser, and bundles with Rollup for production. The replacement for webpack in most new projects.
**[esbuild](https://github.com/evanw/esbuild#readme)** — `v0.28.0`
A JavaScript and TypeScript bundler written in Go. Extremely fast — 10-100x faster than webpack or Rollup. Used as the engine inside Vite and many other tools. Good for simple bundling; less configurable than webpack.
**[turbo](https://turborepo.dev)** — `v2.9.8`
A build system for JavaScript/TypeScript monorepos. Caches task results so you only re-run what changed. Built by Vercel. Speeds up CI and local builds in large codebases with multiple packages.
**[biome](https://www.npmjs.com/package/biome)** — `v0.3.3`
A single tool that replaces both ESLint and Prettier. Formats and lints JavaScript, TypeScript, JSON, and CSS. Written in Rust, so it runs much faster than the JS-based tools it replaces.
**[bun](https://bun.com)** — `v1.3.13`
A JavaScript runtime, package manager, bundler, and test runner in one. Faster than Node.js at most things. Drop-in compatible with most Node.js code. Written in Zig.
**[vitest](https://vitest.dev)** — `v4.1.5`
A unit testing framework built specifically for Vite projects. Uses the same config as your Vite build, runs tests in the browser environment, and is significantly faster than Jest.
**[oxc](https://github.com/jasonmccreary/oxc)** — `v1.0.1`
A JavaScript/TypeScript toolchain written in Rust — parser, linter, formatter, transpiler, bundler. The project behind the oxlint linter. Faster than most existing tools by a large margin.
**[rspack](https://www.npmjs.com/package/rspack)** — `v0.1.1`
A webpack-compatible bundler written in Rust. Drop-in replacement for webpack with the same config format, but much faster. Built by ByteDance (TikTok's parent).
**[wrangler](https://github.com/cloudflare/workers-sdk#readme)** — `v4.87.0`
The CLI for deploying and managing Cloudflare Workers — serverless functions that run at the edge in Cloudflare's global network. Also manages KV storage, Durable Objects, Pages, and R2.
**[drizzle-orm](https://orm.drizzle.team)** — `v0.45.2`
A TypeScript ORM that lets you write SQL-like queries in TypeScript with full type safety. Lightweight, no code generation step, and closer to raw SQL than ORMs like Prisma.
