strip-ansi-modern

Modern, TypeScript-first, zero-dependency replacement for legacy strip-ansi. Correctly removes ANSI escape sequences (SGR colors, cursor movement, erases, OSC, and more) with a compact implementation.

Installation

npm install strip-ansi-modern

Usage

ESM

import stripAnsi, { stripAnsi as strip } from 'strip-ansi-modern';

console.log(stripAnsi('\x1B[31mRed\x1B[0m')); // "Red"
console.log(strip('\x1B[1mBold\x1B[0m text')); // "Bold text"

CommonJS

const pkg = require('strip-ansi-modern');
const stripAnsi = pkg.default; // default export
// Or named export:
// const { stripAnsi } = require('strip-ansi-modern');

console.log(stripAnsi('\x1B[32mGreen\x1B[0m')); // "Green"

API

• stripAnsi(input: string): string — returns input with all ANSI/ECMA-48 escape sequences removed.

Why this package?

• TypeScript-first with generated d.ts types.
• Zero runtime dependencies.
• ESM + CJS builds: dist/index.mjs, dist/index.cjs.
• Small output with tree-shaking and minification.

Build, Test, Benchmark

• Build: npm run build
• Test: npm test
• Benchmark: npm run build && node scripts/benchmark.js

Publish Checklist

1. Ensure Node and npm are up-to-date.
2. Clean install: npm ci
3. Lint & tests: npm run lint && npm test
4. Build: npm run build
5. Publish to npm: npm publish --access public
6. (Optional) Measure size: npx size-limit or inspect dist/ artifacts.

Notes

This package intends to be a drop-in, modern replacement for strip-ansi, prioritizing correctness across common terminal sequences while keeping code size small and dependencies at zero.
