    Bowser Mini

    This is an exact copy of Bowser, except smaller, and only returns something a logger can parse in a much smaller space. Use the below mapper object to translate the short string.

    This package is ideal if you're storing log or analytic data.

    String format

    The string returned is 3 variables, separated by commas.

    Variable 1: The Browser/OS/Platform/Engine types.

    • Byte 1: Browser
    • Byte 2: OS
    • Byte 3: Platform
    • Byte 4: Engine

    Variable 2: The Browser version.

    Variable 3: The OS version.

    The Mapper Object...

      browser: { // Byte 1

    A small, fast and rich-API browser/platform/engine detector for both browser and node.

    • Small. Use plain ES5-version which is ~4.8kB gzipped.
    • Optimized. Use only those parsers you need — it doesn't do useless work.
    • Multi-platform. It's browser- and node-ready, so you can use it in any environment.

    The library is made to help to detect what browser your user has and gives you a convenient API to filter the users somehow depending on their browsers.

    ⚠️ Version 2.0 breaking changes ⚠️

    Version 2.0 has drastically changed the API. All available methods are on the docs page.

    For legacy code, check out the 1.x branch and install it through npm install bowser@1.9.4.

    Use cases

    First of all, require the library. This is a UMD Module, so it will work for AMD, TypeScript, ES6, and CommonJS module systems.

    const Bowser = require("bowser"); // CommonJS
    import * as Bowser from "bowser"; // TypeScript
    import Bowser from "bowser"; // ES6 (and TypeScript with --esModuleInterop enabled)

    By default, the exported version is the ES5 transpiled version, which do not include any polyfills.

    In case you don't use your own babel-polyfill you may need to have pre-built bundle with all needed polyfills. So, for you it's suitable to require bowser like this: require('bowser/bundled'). As the result, you get a ES5 version of bowser with babel-polyfill bundled together.

    You may need to use the source files, so they will be available in the package as well.
