TL;DR
The fastest-growing packages in 2026 share a pattern: Rust-based speed, TypeScript-first APIs, and server-side rendering support. Biome, Oxc, Bun's npm client, Hono, Drizzle, and Conform all grew 100%+ year-over-year. These aren't new packages getting initial hype — they're packages that went from niche to mainstream. The common thread: they replace slow JavaScript tools with fast Rust implementations, or they make server-first patterns ergonomic.
Key Takeaways
- Rust-based tools (Biome, Oxc, SWC, Rspack) growing fastest in tooling category
- Server-first packages (Hono, Conform, Drizzle) growing with Next.js/RSC adoption
- Bundle size wins driving migrations (Zod → Valibot, Moment → date-fns)
- Downloads ≠ hype — these packages are growing on real project migrations
- AI tooling is the newest fast-growing category (OpenAI SDK, Anthropic SDK, Vercel AI)
#1–5: Tooling Revolution
1. Biome — 280% YoY Growth
# Replaces: ESLint + Prettier
# Why growing: 25x faster, one tool instead of two, zero config
npm install -D @biomejs/biome
# Weekly downloads: ~900K (from ~240K a year ago)
# Key milestone: shadcn/ui switched to Biome in 2025
# Signal: "biome migrate eslint" command made migration trivial
2. Oxc — 340% YoY Growth (from smaller base)
# Oxc: Oxidation Compiler — Rust-based JS toolchain
# Components: parser, linter, resolver, transformer, minifier
npm install -D oxc-transform
# Still early-stage but adoption accelerating fast
# Used by: Rolldown (Rust-based Rollup replacement), Vite internals
# Signal: Vite announced migrating core to Rolldown/Oxc in 2025
3. Rspack — 220% YoY Growth
# Replaces: Webpack (drop-in compatible)
# Why growing: webpack.config.js works unchanged, 5-10x faster builds
npm install -D @rspack/core @rspack/cli
# Weekly downloads: ~400K (from ~125K)
# Used by Bytedance (creators) and BytePlus products
# Rsbuild: higher-level config tool built on Rspack, growing even faster
4. Bun Runtime — 180% YoY Growth
# Not just a runtime — bun install is npm-compatible and 3x faster
curl -fsSL https://bun.sh/install | bash
bun install # Drop-in for npm install
# Weekly installs: hard to measure (runtime metric ≠ npm metric)
# Signal: many CI configs now do: curl bun | bash && bun install
# Fastest growing use case: running Next.js apps on Bun runtime
5. Rolldown — New in 2026, Rapid Growth
# Rust-based Rollup replacement — same API
# Built with Oxc as the parser
npm install -D rolldown
# Not yet in Vite core but in active integration
