Hammer is not defined error after Angular 8 Update

akrolis pro asked 5 years ago

Expected behavior The code provided in the docs (https://mdbootstrap.com/docs/angular/advanced/mobile/) worked with Angular 7.3.9 and MDB 7.5.4

Actual behavior After I updated the project to Angular 8.1.0 & MDB 8.0.0 the app crashes and I got this error in the browser console:ERROR ReferenceError: Hammer is not defined

Resources (screenshots, code snippets etc.) I used the code available at: https://mdbootstrap.com/docs/angular/advanced/mobile/

Error:

Dear @akrolis

Do you have installed HammerJS and imported/configured it properly?

I have tried to reproduce this problem but without success.

Please check, if your app contains HammerJS and if it is configured properly.

Best Regards,

Damian

Sorry, I don't know what happened, now it seems to be working OK.

Thanks anyway.

Ok I know what happened,

this is my scripts section in angular.son:

"scripts": [
          "node_modules/chart.js/dist/Chart.js",
          "node_modules/easy-pie-chart/dist/easypiechart.js",
          "node_modules/screenfull/dist/screenfull.js",
          "node_modules/hammerjs/hammer.min.js"
        ]

since Charts.js fails as discussed here: https://mdbootstrap.com/support/angular/chart-js-uncaught-typeerror-cannot-read-property-moment-of-undefined/

everything below that seems to fail. I removed Chart.js & easypiechart.js (which also fails) from angular.json and now Hammer is correctly defined and working properly.

I hope for a solution for the Chart.js is implemented soon.
