Pass options as one prop?

[cadilhac]

Would it be possible to pass options like this:

<GoogleMap api-key="..." ref="mapRef" :options="getMapOptions">
</GoogleMap>

function getMapOptions() {
  return {
        zoom: 14,
        center: new google.maps.LatLng(45.481662, -73.628735),
        draggable: true,
        backgroundColor: '#fbf0de',
        scrollwheel: true,
        disableDefaultUI: true,
        panControl: false,
        zoomControl: true,
        mapTypeId: google.maps.MapTypeId.ROADMAP,
        maxZoom: 18,
        minZoom: 5,
        panControlOptions: {
            position: google.maps.ControlPosition.TOP_RIGHT
        },
        zoomControlOptions: {
            position: google.maps.ControlPosition.TOP_RIGHT
        },
        styles: getMapStyles()
  }
}

instead of having to pass each one individually. This makes the template more readable.

As a workaround, I can do this instead:

watch(() => mapRef.value?.ready, (ready) => {
    if (!ready) return

    mapRef.value.map.setOptions(getMapOptions())
})

You could always just use v-bind with an object instead
https://vuejs.org/guide/components/props.html#binding-multiple-properties-using-an-object

Well, if I use v-bind="getMapOptions()" which returns an object that relies on the google instance, then it complains that google is not defined (i.e. the script not loaded yet).

See here:
https://github.com/inocan-group/vue3-google-map#advanced-usage
You can make your options object a computed property that uses the map api once it's ready or falls back to some default value

[cadilhac]

Yes I can do like that. However I notice that I have to change the name of some properties. If I use the ones defined by google, it doesn't work (ex: zoomControlOptions in the google api becomes zoomControlPosition in your api, or disableDefaultUI which has its last letter that changes case).

Because of those differences, I will continue using my workaround because using the google types and names makes more sense to me.

[HusamElbashir]

Correct we opted for simplifying the api when an interface only has one possible property (e.g. position for ZoomControlOptions). There are other issues that had to be factored in such as prop name casing:
https://vuejs.org/guide/components/props.html#prop-name-casing
This is to avoid disableDefaultUI translating into disable-default-u-i when using kebab-case in templates.

So if you have to use your options as is I'm afraid you'll have to use a watcher like you suggested in your initial post.

Thanks for all this information.
