mdbootstrap V9 SSR ReferenceError: KeyboardEvent is not defi


Topic: mdbootstrap V9 SSR ReferenceError: KeyboardEvent is not defined

yuenkai asked 5 years ago

I trying MDBootStrap V9 for SSR. and having error ReferenceError: KeyboardEvent is not defined when i run ==> npm run serve:ssr

  1. Create new angular project
  2. Update styles and scripts arrays in angular.json file
  3. Update the app.module.ts
  4. npm i --save chart.js @types/chart.js easy-pie-chart hammerjs screenfull @fortawesome/fontawesome-free animate.css
  5. ng add @nguniversal/express-engine
  6. npm run build:ssr
  7. npm run serve:ssr ==> Error ReferenceError: KeyboardEvent is not defined

  8. try to run ng serve => success

  9. try to remove MDBootstrap module from app.module.ts and run npm run build:ssr | npm run serve:ssr, it run successfully

is MDBootStrap V9 compatible with Angular Universal?

We will take a closer look at this problem and let you know what we found. Please create a simple demo on which we will be able to reproduce this problem and send it to a.idzikowski@mdbootstrap.com. We need to check the ssr configuration and make sure that we use the same settings while debugging.

Hi. Is there any update on this? I am having the same issue after upgrading to: "Error ReferenceError: KeyboardEvent is not defined"


Arkadiusz Idzikowski staff answered 5 years ago

Thank you for the demo. It looks like there is some bug with Event/KeyboardEvent type annotations in Angular HostListener. We need to change the implementation on our end in order to fix that, this problem should be fixed in next MDB Angular release (withing two weeks).

We tried some common workarounds for this kind of problems, however it looks like they doesn't work in this case. If we find any solution for this problem that you can add to your app before our fix release, we will post it here.


postoliuk pro commented 5 years ago

Hello, two weeks ago you promised fix bug with Event/KeyboardEvent. Do you have any updates?


Arkadiusz Idzikowski staff commented 5 years ago

We added some fixes for that in v9.0.1. Please let us know if you still experience any problems after the upgrade.
