busybox-static

A statically-linked busybox (x86_64, musl) packed as a static file inside the package, with a tiny API to get its path or bytes.

• Binary: 1.35.0-x86_64-linux-musl (upstream busybox.net build)
• Size: ~1.1 MB, ELF 64-bit, statically linked, stripped
• sha256: 6e123e7f3202a8c1e9b1f94d8941580a25135382b99e8d3e34fb858bba311348
• Platform: os: linux, cpu: x64

Install

npm install busybox-static

The binary ships packed at bin/busybox. If it is missing (e.g. a shallow checkout), re-vendor it:

npm run fetch

Usage

const busybox = require('busybox-static');

busybox.binaryPath;   // absolute path to the packed bin/busybox
busybox.exists();     // true if the packed binary is present
busybox.readBytes();  // Buffer of the binary

Run it directly via the package bin:

npx busybox echo hello
npx busybox ls -la /

Or from Node:

const { execFileSync } = require('child_process');
const busybox = require('busybox-static');
console.log(execFileSync(busybox.binaryPath, ['id']).toString());

Notes

• The packed binary is a Linux/x86_64 static build; os/cpu fields keep it from installing on incompatible platforms.
• busybox is licensed GPL-2.0; this package redistributes the upstream binary under that license.
