 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.


  • Using a feature requiring polyfills in IE11:


import 'babel-polyfill'; // Import necessary polyfills

Vue.component('my-component', {
  // ...

  • Configuring browserslist for specific browser support:


// 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.


  • 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.
