default-user-agent

1.0.0 verified Sat Apr 25 auth: no javascript maintenance

Generates a default User-Agent string for Node.js HTTP requests. Version 1.0.0 is stable but unmaintained since 2015. It outputs strings like 'Node.js/<version> (<os>; <arch>)' and accepts optional app name and version (e.g., 'urllib/0.0.1 Node.js/...'). Unlike modern packages like 'useragent' or 'ua-parser-js', it only generates a string and has no parsing capabilities. Works with Node >=0.10.0. No releases or updates in the last 9 years.

fix Consider using a maintained alternative like 'useragent' or manually constructing the User-Agent string.

Quickstart

Shows how to generate a User-Agent string with and without custom app name/version.

const ua = require('default-user-agent');

// Generate default user-agent
console.log(ua()); // e.g., 'Node.js/14.17.0 (OS X 10.15; x64)'

// Generate with custom app name and version
console.log(ua('myapp', '1.2.3')); // 'myapp/1.2.3 Node.js/14.17.0 (OS X 10.15; x64)'
