detect-browser

What is detect-browser?

The detect-browser npm package is used to determine information about the browser or node version that the code is running in. It can detect the browser name, version, and operating system. This is particularly useful for client-side scripting where you might need to tailor behavior or workarounds for specific browsers or versions.

What are detect-browser's main functionalities?

Detecting browser information

This feature allows you to detect the browser name, version, and operating system. The `detect` function returns an object with this information if it's able to determine it, otherwise it returns `null`.

const { detect } = require('detect-browser');
const browser = detect();
if (browser) {
  console.log(browser.name);
  console.log(browser.version);
  console.log(browser.os);
}

Detecting node information

This feature is used to detect if the code is running in Node.js and to determine the Node.js version. The `detect` function returns an object with the version if the environment is Node.js.

const { detect } = require('detect-browser');
const browser = detect();
if (browser && browser.type === 'node') {
  console.log(browser.version);
}

Bot detection

This feature allows you to detect if the user-agent is a bot. The `detect` function returns an object with a `bot` property set to `true` if a bot is detected.

const { detect } = require('detect-browser');
const browser = detect();
if (browser && browser.bot) {
  // Handle bot-specific logic
}

Other packages similar to detect-browser

platform

The 'platform' package is similar to 'detect-browser' as it can also parse the browser and operating system information from the user-agent string. It provides a more detailed breakdown of the operating system, device, and even the type of browser engine being used. However, it does not provide a simple API specifically for browser detection and may include more information than necessary for some use cases.

ua-parser-js

The 'ua-parser-js' package is another alternative that parses the user-agent string to detect browser, engine, OS, CPU, and device type/model. It is more comprehensive than 'detect-browser' and is regularly updated with new user-agent strings. However, it might be overkill for simple browser detection tasks and has a larger footprint.

bowser

The 'bowser' package is a robust parser for browser user-agent strings. It provides detailed information about the browser, including whether it is a mobile browser, if it's a webview, and the platform's type (tablet, mobile, desktop, tv, etc.). It is more feature-rich compared to 'detect-browser' but also larger in size, which might be a consideration for front-end use.

README

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.

Example Usage
