What is the browser support of VueJS in Vuejs explain with example?
Here's a breakdown of Vue.js browser support:
Supported Browsers:
Chrome (latest and 2 prior versions)
Firefox (latest and 2 prior versions)
Safari (latest and 2 prior versions, excluding iOS 14.5 and below)
Edge (latest and 2 prior versions)
Internet Explorer 11 (with polyfills)
Key Considerations:
ES5 Compatibility: Vue.js code is written in ES5, ensuring compatibility with most modern browsers.
Polyfills: For older browsers like IE11, polyfills might be needed for certain features (e.g., Object.defineProperty, Promise).
Browserslist Configuration: Use browserslist in your project to specify target browsers and automate polyfill inclusion.
Runtime-Only Builds: Consider runtime-only builds for smaller production bundles and potentially wider browser compatibility.
Testing: Thoroughly test your application across supported browsers to ensure consistent behavior.
Examples:
Using a feature requiring polyfills in IE11:
JavaScript
import 'babel-polyfill'; // Import necessary polyfills
Vue.component('my-component', {
// ...
});
Configuring browserslist for specific browser support:
JSON
// package.json
"browserslist": [
"> 1%",
"last 2 versions",
"not dead"
]
Additional Notes:
Vue CLI: Vue CLI automatically configures polyfills based on your browserslist settings.
Community-Supported Builds: Experimental builds for older browsers (e.g., IE10) might be available from the community, but official support is limited.
Remember:
Prioritize supporting modern browsers for optimal performance and feature availability.
Use polyfills judiciously to balance compatibility with bundle size.
Regularly test your application in target browsers to ensure seamless user experiences.
