detect-browser

This is a package that attempts to detect a browser vendor and version (in a semver compatible format) using a navigator useragent in a browser or process.version in node.

NPM

Example Usage

const browser = require('detect-browser');
 
// handle the case where we don't detect the browser
if (browser) {
  console.log(browser.name);
  console.log(browser.version);
}
 

Or you can use a switch statement:

const browser = require('detect-browser');
 
// handle the case where we don't detect the browser
switch (browser && browser.name) {
  case 'chrome':
  case 'firefox':
    console.log('supported');
    break;
 
  case 'edge':
    console.log('kinda ok');
    break;
 
  default:
    console.log('not supported');
}
 

Adding additional browser support

The current list of browsers that can be detected by detect-browser is not exhaustive. If you have a browser that you would like to add support for then please submit a pull request with the implementation.

Creating an acceptable implementation requires two things:

  1. A test demonstrating that the regular expression you have defined identifies your new browser correctly. Examples of this can be found in the test/logic.js file.

  2. Write the actual regex to the lib/detectBrowser.js file. In most cases adding the regex to the list of existing regexes will be suitable (if usage of detect-brower returns undefined for instance), but in some cases you might have to add it before an existing regex. This would be true for a case where you have a browser that is a specialised variant of an existing browser but is identified as the non-specialised case.

When writing the regular expression remember that you would write it containing a single capturing group which captures the version number of the browser.
