Last verified Sep 9, 2026 against data-view-byte-offset@1.0.1.

data-view-byte-offset ships CommonJS only. require("data-view-byte-offset") works on every Node.js version we test (18, 20, 22, 24 and 26) and in Bun. The package declares Node.js >= 0.4. import "data-view-byte-offset" 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("data-view-byte-offset") works on every Node.js version we test (18, 20, 22, 24 and 26) and in Bun. The package declares Node.js >= 0.4.
2. From ES modules use the default import: import dataViewByteOffset from "data-view-byte-offset"; then destructure. Named imports only work when Node.js can statically detect the exports.
3. TypeScript: types are bundled; install nothing extra.
