Found the synthetic property panelState Please include either BrowserAnimationsModule or NoopAnimationsModule in your application

Question

I upgraded an Angular 4 project using angular-seed and now get the error     Found the synthetic property  panelState  Please include either  BrowserAnimationsModule  or  NoopAnimationsModule  in your application      How can I fix this  What exactly is the error message telling me

For me was because I put the animation name inside square brackets.

<div [@animation]></div>

But after I removed the bracket all worked fine (In Angular 9.0.1):

<div @animation></div>

All I had to do was to install this   npm install  angular animations latest --save     and then import   import   BrowserAnimationsModule   from   angular platform-browser animations      into your app module ts file

User · Answer

This error message is often misleading    You may have forgotten to import the BrowserAnimationsModule  But that was not my problem   I was importing BrowserAnimationsModule in the root AppModule  as everyone should do   The problem was something completely unrelated to the module  I was animating an ngIf in the component template but I had forgotten to mention it in the  Component animations for the component class    Component     selector           templateUrl             animations   myNgIfAnimation      lt -- Don t forget       If you use an animation in a template  you also must list that animation in the component s animations metadata     every time

After installing an animation module then you create an animation file inside your app folder      router animation ts   import   animate  state  style  transition  trigger   from   angular animations       export function routerTransition             return slideToTop               export function slideToRight             return trigger  routerTransition                 state  void   style                   state      style                   transition   enter                     style   transform   translateX -100                        animate  0 5s ease-in-out   style   transform   translateX 0                                    transition   leave                     style   transform   translateX 0                        animate  0 5s ease-in-out   style   transform   translateX 100                                              export function slideToLeft             return trigger  routerTransition                 state  void   style                   state      style                   transition   enter                     style   transform   translateX 100                        animate  0 5s ease-in-out   style   transform   translateX 0                                    transition   leave                     style   transform   translateX 0                        animate  0 5s ease-in-out   style   transform   translateX -100                                              export function slideToBottom             return trigger  routerTransition                 state  void   style                   state      style                   transition   enter                     style   transform   translateY -100                        animate  0 5s ease-in-out   style   transform   translateY 0                                    transition   leave                     style   transform   translateY 0                        animate  0 5s ease-in-out   style   transform   translateY 100                                              export function slideToTop             return trigger  routerTransition                 state  void   style                   state      style                   transition   enter                     style   transform   translateY 100                        animate  0 5s ease-in-out   style   transform   translateY 0                                    transition   leave                     style   transform   translateY 0                        animate  0 5s ease-in-out   style   transform   translateY -100                                           Then you import this animation file to your any component      In your component ts file   import   routerTransition   from        router animations     Component     selector   app-test     templateUrl     test component html     styleUrls      test component scss      animations   routerTransition            Don t forget to import animation in your app module ts   import   BrowserAnimationsModule   from   angular platform-browser animations
