Bytes go in, but they don't come out (when muted).

Last verified Sep 9, 2026 against mute-stream@4.0.0.

mute-stream ships CommonJS only. require("mute-stream") works on every Node.js version we test (18, 20, 22, 24 and 26) and in Bun. The package declares Node.js ^22.22.2 || ^24.15.0 || >=26.0.0. import "mute-stream" also works because Node.js and Bun can import CommonJS from ES modules, but only the default export is guaranteed; named imports depend on Node's static analysis of the module.

## What to do

1. require("mute-stream") works on every Node.js version we test (18, 20, 22, 24 and 26) and in Bun. The package declares Node.js ^22.22.2 || ^24.15.0 || >=26.0.0.
2. From ES modules use the default import: import muteStream from "mute-stream"; then destructure. Named imports only work when Node.js can statically detect the exports.
3. TypeScript: npm install -D @types/mute-stream
