HTMLElement is not defined - Nativescript-vue

Question

All I'm trying to do at this point is get the project to run.

I run tns run android

The application builds, but as it starts the app and throws an error

ReferenceError: HTMLElement is not defined

So this all started when I was trying to bring in the new nativescript theme core (2.2.0). I followed the guide they have posted in several places. Everything looked good. Then I ran tns run android and got the HTMLElement is not defined error for the first time.

• I've blown away the node_modules and platform folder
• npm rebuild
• tns install
• I've uninstalled nativescript-cli & cleared npm cache and re-installed (As mentioned here: https://discourse.nativescript.org/t/enoent-no-such-file-or-directory-project-pbxproj/7336)

I then decided to start again proceed to start with a clean project. Following the steps here: https://nativescript-vue.org/en/docs/getting-started/quick-start/

And when I run tns run android I still get the same HTMLElement is not defined error, even when I didn't modify the template at all.

I don't know if this is a bug or if I'm doing something horribly wrong

tns --version 6.1.2

node -v 12.10.0

npm -v 6.10.3

So I am now getting this error no matter what I do now...

Code wise like I said I am getting this error with a clean pull of this template repo: https://github.com/nativescript-vue/vue-cli-template

Here is the Stack.

Answer 1

I found the solution, update your main.js file

import store from './store' // <= this should be before VueDevtools 
import VueDevtools from 'nativescript-vue-devtools';

Answer 2

The solution that @sidheart pointed out works but it will not let you observe the store. The error is triggered because NativeScript does not have a DOM and therefore has no types for HTMLElement. A temporary solution is to add the line below to the object defined by new webpack.DefinePlugin({}) in the file webpack.config.js:

HTMLElement: function() {
 return false;
},

so that the full object looks like this:

new webpack.DefinePlugin({
  'global.TNS_WEBPACK': 'true',
  TNS_ENV: JSON.stringify(mode),
  process: 'global.process',
  HTMLElement: function() {
    return false;
  },
}),

Thanks to Brandon Gohsman for showing this solution in his article.

Answer 3

When you create a project using:

vue init nativescript-vue/vue-cli-template <project-name>

Don't install vue-devtools. I think it has something to do with vue-devtools trying to access the DOM which doesn't exist in Nativescript.
