ESLint is Now Language-Agnostic: Linting JSON, Markdown, and Beyond
ESLint has added JSON and Markdown linting support with new officially-supported plugins, expanding its versatility beyond JavaScript.
The bowser npm package is a browser detection library. It helps in identifying the browser and rendering engine a user is using, as well as providing information about the browser's capabilities, such as whether it supports touch events or service workers. This can be particularly useful for tailoring user experiences to different environments or for analytics and debugging purposes.
Browser Detection
Detects the browser name using the user agent string.
const Bowser = require('bowser');
const browser = Bowser.getParser(window.navigator.userAgent);
const browserName = browser.getBrowserName();
Browser Version Detection
Determines the version of the browser being used.
const Bowser = require('bowser');
const browser = Bowser.getParser(window.navigator.userAgent);
const browserVersion = browser.getBrowserVersion();
Platform Detection
Identifies the platform (desktop, mobile, tablet, etc.) on which the browser is running.
const Bowser = require('bowser');
const browser = Bowser.getParser(window.navigator.userAgent);
const platformType = browser.getPlatformType();
Feature Checks
Checks if the browser supports certain features, such as touch events.
const Bowser = require('bowser');
const browser = Bowser.getParser(window.navigator.userAgent);
const supportsTouch = browser.satisfies({
'mobile': { 'touch': true }
});
OS Detection
Determines the operating system on which the browser is running.
const Bowser = require('bowser');
const browser = Bowser.getParser(window.navigator.userAgent);
const osName = browser.getOSName();
The 'useragent' package is similar to 'bowser' in that it parses user agent strings to detect browser information. However, it focuses more on the parsing aspect and less on the browser's capabilities.
The 'platform' package provides information about the operating system, browser, and device based on the user agent string. It is similar to 'bowser' but has a simpler API and less detailed detection of browser features.
The 'detect-browser' package is another alternative for detecting browser information from the user agent string. It is a smaller and more lightweight library compared to 'bowser', but it may not offer as comprehensive feature detection.
A Browser detector. Because sometimes, there is no other way, and not even good modern browsers always provide good feature detection mechanisms.
So... it works like this:
if (bowser.msie && bowser.version <= 6) {
alert('Hello China');
}
Safari, Chrome, and Firefox will report that they have webkit|gecko engines
if (bowser.webkit) {
// do stuff with safari & chrome
}
If you don't already have Ender (an npm package) install it now (and don't look back)
$ npm install ender
then add bowser to your module collection
$ ender add bowser
use it like this:
if ($.browser.chrome) {
alert('Hello Silicon Valley');
}
One useful feature of Bowser is that aside from checking one browser from another -- it will keep up to date with Yahoo's Graded Browser Support chart, giving you access to each grade on the bowser object
if (bowser.a) {
// support full feature set
}
else if (bowser.c) {
// serve degraded version
}
else {
// unsupported (bowser.x)
}
