Episode 102 - Angular Elements + Firebase

Build a custom Angular Elements Component and use it anywhere.

git clone
npm install
npm run build:elements

This will create the custom component elements/user-poll.js.

Usage

You can use your custom Angular Elements component in any HTML page like so...

<user-poll></user-poll>
<script src="../elements/user-poll.js"></script>

Or simply open {local-path-to}/demo/index.html in your browser.

error on clean install: Property 'automaticDataCollectionEnabled' is missing in type 'FirebaseApp'

ERROR in node_modules/angularfire2/firebase.app.module.d.ts(10,22): error TS2720: Class 'FirebaseApp' incorrectly implements class 'FirebaseApp'. Did you mean to extend 'FirebaseApp' and inherit its members as a subclass?
Property 'automaticDataCollectionEnabled' is missing in type 'FirebaseApp'.

I get this error when i clone and run. I can fix this by installing: "@firebase/app": "^0.1.10". This has to do with the latest version of firestore I guess.

Error with angular 7.2.*

I get this error to try to test element in outside

error: 'Schema validation failed with the following errors: Data path ".outputHashing" should be equal to one of the allowed values.'

When running "build:elements": "ng build --prod --output-hashing none && node build-script.js" on Windows 10, the script failed because of the output-hashing false.
