ES5 Transpilation

This package is distributed with ES2015 style code. Which means it is perfectly fine for modern browsers (Chrome, Firefox, Safari), but will not work on IE11. If you are using IE11 you are probably having a Babel-based transpilation setup to generate ES5 code. If that's the case, you need to make sure this package also gets transpiled.

Add this in your vue.config.js (Vue CLI v3)

// vue.config.js
module.exports = {
  // ... your other options
  transpileDependencies: [

Transpiler Configurations

Babel 6/7

  1. You need to install babel-plugin-transform-decorators


  1. set experimentalDecorators to true
  2. (Tip) For reduced code with decorators, set emitHelpers: true and importHelpers: true


We do not need emitDecoratorMetadata as we do not depend on reflect-metadata
