Usage

If you are upgrading: please see the changelog.

const detect = require('win-detect-browsers')

// All browsers
detect(function (err, browsers) {
  if (err) throw err
  console.log(browsers)
})

// Chrome and Firefox
detect(['chrome', 'firefox'], function (err, browsers) {
  if (err) throw err

  for (let b of browsers) {
    console.log(b.version) // '57.0.2931.0'
    console.log(b.channel) // 'canary'
  }
})

API

detect([names, ]callback)

names is an array of browser names you want to find. If omitted or empty, it will detect everything. The callback receives an error if any and an array of results. A result is excluded if its path has no .exe extension or if its version could not be read.

Each result is an object with the following properties:

  • name (string): chrome, chromium, firefox, phantomjs, ie, safari, opera, maxthon or yandex
  • path (string): absolute path to executable
  • version (string)
  • arch (string): CPU type the executable was built for: amd64, i386 or other;
  • info (object): executable metadata (see full sample below).

Additional properties are usually available but not guaranteed:

  • channel (string):
    • Chrome: stable, canary, beta or dev
    • Firefox: release, developer, nightly or esr
    • Older versions of Firefox: aurora, beta or rc;
    • Opera: stable, beta or developer.
  • uninstall (object): Chrome only. Uninstaller info with:
    • path (string): path to installer;
    • arguments (array): arguments to installer in order to uninstall.
  • bitness (number): Chrome only. 64 or 32.
  • guid (string): Chrome only.

CLI

win-detect-browsers [options] [name, name..]

Options:

  • --help -h: Show help
  • --version -v: Show CLI version number
  • --json -j: Print results as JSON array
  • --summary -s: Less properties;

## Install

With [npm](https://npmjs.org) do:

```source-shell
npm install win-detect-browsers     # For API
npm install win-detect-browsers -g  # For CLI

Background

Browser detection on Windows can’t be done right. This is the try-everything-and-fail-silently approach. It accounts for architecture differences, normalizes environment variables, tries default locations, searches the registry (in the HKLM and HKCU hives as well as WoW counterparts) (including Start Menu Internet Applications, Google Updater and more), and looks in PATH. Version numbers are then read from the executable metadata.

browser-launcher by substack has poor Windows support, and it prompted me to create this module. It is now used in browser-launcher2, an active a once active fork of browser-launcher.
