Trouble getting Angular Google Map AGM to work with Angular 11

Question

I installed agm/core using npm like this:

npm install @agm/core

The following warnings were displayed:

npm WARN @agm/[email protected] requires a peer of @angular/common@^9.1.0 || ^10.0.0 but none is installed. You must install peer dependencies yourself.
npm WARN @agm/[email protected] requires a peer of @angular/core@^9.1.0 || ^10.0.0 but none is installed. You must install peer dependencies yourself.

I continued nevertheless and imported AgmCoreModule into AppModule as per docs like this:

AgmCoreModule.forRoot({
      apiKey: 'MY MAP KEY',
      libraries: ['places']
    })

However, when trying to serve the app with ng serve, the following errors occur:

Error: node_modules/@agm/core/lib/services/google-maps-api-wrapper.d.ts:50:41 - error TS2314: Generic type 'MapHandlerMap<T>' requires 1 type argument(s).

I have this working on an existing Angular 7 application already. But I am trying to upgrade to Angular 11 and having problems getting @agm/core to work.

I am also aware of an official Angular google-map component, but I need to use the autocomplete feature that seems to integrate well with agm, and couldn't find any docs to do this with the google-map component.

Has anyone managed to successfully use @agm/core with Angular 11?
Help and suggestions much appreciated.

Answer 1

I had the same issue and I found in other forums where rolling back the version of the googlemaps fixed it. I ran the following command and I was able to see it work as expected.

npm i @types/[email protected] --save-dev

Answer 2

Sorry for late response. I opted to use the google-map component from Angular that works well in Angular 11+

You can find more info here:

Thank you for all the comments and suggestions for the problem with AGM.
However, I stopped using AGM in favour of the google-map component. It made more sense since it is supported directly in Angular. So unfortunately I am unable to confirm whether the suggested solutions work for AGM.

I do recommend using google-map instead if you experience problems with AGM in Angular 11+
