Introduction

Teachers spend hours every week calculating grades, curving scores, and converting percentages to letter grades. Most of this work happens in spreadsheets with fragile formulas that break the moment a student is added out of order.

What if we packaged those utilities as a reusable TypeScript library — something any teacher or school app developer could npm install and use?

In this post, we'll build teacher-toolkit — an npm package for grade calculations — using Vite+ and its vp pack command. No Webpack config. No tsconfig gymnastics. Just code, test, and ship.

Introduction

If you've been juggling Node version managers, package managers, linters, formatters, test runners, and build tools — you're not alone. The JavaScript tooling landscape has gotten out of hand.

Vite+ aims to fix that. Created by VoidZero — the team behind Vite, Vitest, Oxc, and Rolldown — it unifies your entire development workflow into a single CLI tool called vp.

Introduction

The JavaScript ecosystem is evolving fast, and Bun is leading the charge. Since its 1.0 release, Bun has proven itself as a legitimate alternative to Node.js—offering significantly faster startup times, native TypeScript support, and an all-in-one toolkit that includes a package manager, bundler, and test runner.

When paired with Nitro, you get a server stack that's both incredibly fast and deployment-agnostic.

In this post, we'll explore:

• Why Bun matters in 2026
• Setting up Bun with Nitro
• Performance benefits and benchmarks
• Migration strategies from Node.js
• Real-world deployment

Let's build the fastest server stack you've ever used.
