Modernize toolchain: esbuild + vitest + GitHub Actions (#59)
* Modernize toolchain: esbuild + vitest + GitHub Actions Replace legacy dev stack (browserify, uglify-js, mocha, budo, assert) with esbuild and vitest. Adds GitHub Actions CI (Node 18/20/22), removes Travis CI. - 395 → 131 packages, 32 → 0 vulnerabilities - Build time: ~2s → 3ms - All 9 tests passing Co-Authored-By: Claude Opus 4.6 (1M context) <noreply@anthropic.com> * Address Copilot review feedback - Drop Node 18 from CI matrix (vitest/vite requires >=20.19.0) - Use npm ci instead of npm install in CI - Update CLAUDE.md commands to reflect new toolchain - Fix CLAUDE.md ESLint wording (not enforced in CI) Co-Authored-By: Claude Opus 4.6 (1M context) <noreply@anthropic.com> * Address remaining review feedback - Bump esbuild ^0.27.0, vitest ^4.1.0 (all deps latest) - Remove engines field (unnecessary for a lib) - Add Node 24 to CI matrix - Remove visual-demo.js and its README reference - Fix README: correct lib path (src/index.js), typo Co-Authored-By: Claude Opus 4.6 (1M context) <noreply@anthropic.com> * Fix example/index.html to use dist bundle Co-Authored-By: Claude Opus 4.6 (1M context) <noreply@anthropic.com> --------- Co-authored-by: greweb <greweb@protonmail.com> Co-authored-by: Claude Opus 4.6 (1M context) <noreply@anthropic.com>

# CLAUDE.md

This file provides guidance to Claude Code (claude.ai/code) when working with code in this repository.
4+
5+
## Overview
6+
7+
bezier-easing is a micro-library that provides cubic Bezier curve easing functions, equivalent to CSS `transition-timing-function: cubic-bezier(...)`. It uses Newton-Raphson iteration, binary subdivision, and precomputed sample tables for fast, precise x→y projection on Bezier curves.
8+
9+
## Commands
10+
11+
- **Test:** `npm test` (runs vitest)
12+
- **Benchmark:** `npm run benchmark`
13+
- **Build:** `npm run prepublish` (esbuild → dist/)
14+
15+
## Architecture
16+
17+
Single-file library (`src/index.js`) exporting a factory function `bezier(mX1, mY1, mX2, mY2)` that returns an easing function `(x) => y`. X values must be in [0, 1]; Y values are unconstrained. Linear curves (where x1===y1 && x2===y2) short-circuit to identity.
18+
19+
The algorithm precomputes 11 sample points on the curve, then for a given x: looks up the nearest sample interval, estimates t via linear interpolation, and refines using Newton-Raphson (if slope is steep enough) or binary subdivision (fallback).
20+
21+
## Code Style
22+
23+
2-space indent, single quotes, semicolons, unix line endings (`.eslintrc` present but eslint not in devDependencies).
