Add vue.config.js file with the following content:

module.exports = {

}

Open src/main.js and

In the import section, add:

Open src/App.vue

  • Replace all HTML in the <template> with:
<div>
  <vaadin-text-field ref="textField" id="text" placeholder="Type Something"></vaadin-text-field>
  <vaadin-button @click="clicked">Click Me!</vaadin-button>
  <h2>Hello {{msg}}!</h2>
</div>

base-starter-vue's Issues

Dependencies do not transpile for IE11

I downloaded the repo and executed the build command. Afterwards I checked the generated chunk-vendors JS File.

Even with the transpileDependencies Option there are still Arrow-Functions and other ES6-Features contained in the output.

This only affects the dependencies. If I add e.g. Arrow Functions in the App Code, they get transpiled correctly.

Could you check this?

Thanks!

Update repo to use vue-cli 3.0.0

Currently, @vue/cli 3.0.1 uses Babel 7.0.0-beta.47 which does not work nice with Custom Elements.
Once the Babel version there gets updated to stable 7.0.0, we need to update this repo once again.

Needs vuejs/vue-cli#2376

P3 preview branch build is failing

For some reason, UglifyJS is failing on Polymer source code:

$ yarn build
yarn run v1.9.4
$ cross-env NODE_ENV=production webpack --progress --hide-modules
Hash: 7fe83019d2cf69950d59
Version: webpack 3.12.0
Time: 2634ms
       Asset    Size  Chunks                    Chunk Names
    build.js  811 kB       0  [emitted]  [big]  main
build.js.map  980 kB       0  [emitted]         main

ERROR in build.js from UglifyJs
Unexpected token: name (dedupeId) [./node_modules/@polymer/polymer/lib/utils/mixin.js:13,0][build.js:102,4]

Makes sense to verify after fixing #9

P3 preview branch is not working in IE11

Trying to bundle needed webcomponents-bundle.js results in the following error:

webcomponents-bundle.js?e897:55 Uncaught TypeError: Cannot redefine property: iterator
    at defineProperty (<anonymous>)
    at Function.f (webcomponents-bundle.js?e897:55)
    at Object.eval (webcomponents-bundle.js?e897:60)
    at Object.eval (webcomponents-bundle.js?e897:251)
    at eval (webcomponents-bundle.js?e897:253)
    at Object.<anonymous> (build.js:1119)
    at __webpack_require__ (build.js:679)
    at fn (build.js:89)
    at eval (56:3)
    at Object.<anonymous> (build.js:1107)

Need to figure out what part of the recently added Symbol polyfill causes this to happen.
