kandi X-RAY | google-map-react Summary
google-map-react is a component written over a small set of the Google Maps API. It allows you to render any React component on the Google Map. It is fully isomorphic and can render on a server. Additionally, it can render map components in the browser even if the Google Maps API is not loaded. It uses an internal, tweakable hover algorithm - every object on the map can be hovered. It allows you to create interfaces like this example (You can scroll the table, zoom/move the map, hover/click on markers, and click on table rows). The development of this package is sponsored by Atlist. Atlist is a no-code tool for creating custom maps with multiple markers.

QUESTION
I am trying to center the map in the geoposition and I get the following error:
Uncaught TypeError: Cannot read properties of undefined (reading 'coords')
If I console log the position in the getLocationHandler, the object seems to have the coordinates.
...ANSWER
Answered 2022-Mar-30 at 20:36On your first render, position
will be undefined so when you're trying to use position.coords.latitude
it's throwing that error. I would probably leverage your isLoading
state and only render the second part of your component when that is false -
QUESTION
I'm using google-map-react
to display places on google map with auto-suggestion feature, following example here: https://www.freakyjolly.com/google-maps-in-react-example-application. I'm using Typescript so my code is different from the blog.
I'm having a problem right now : console.log(autoComplete);
in function onPlaceChanged
print undefined
. Any idea why this is happening, and how can I fix it?

This is because you are closing over the initial undefined autoComplete
state in the callback.
QUESTION
I'm trying to use google-map-react
to show local bakery stores.
However, the line console.log(props);
in my child component StoresGoogleMap
prints storeLocations
and stores
as []
. If I use below instead in my StoresGoogleMap
component, the it is working:
ANSWER
Answered 2022-Feb-22 at 04:13So I think here the problem is that the child component StoresGoogleMap is rendered with initial value in parent component SearchStoresPage, which is []. But not updated when parent component's state changed. Any suggestion how to fix this?
A way to fix this is to fire useEffect
in your child component when data in parent component changes --> By adding props.storeLocations
as a dependency in StoresGoogleMap
useEffect()
QUESTION
I have a Google map in my react application which allows users to sign up (by entering their name). It then gets their location every 1 second and sends it to all the other users currently using the app.
I am trying to plot the users on a map using google-map-react. This should update every time a user is added, or their location changes and reflect this with their marker moving on the map.
It is console logging the usersArray correctly, but users is not being updated, am I doing setState wrong?
...ANSWER
Answered 2022-Feb-21 at 12:32You should check if user exist first. Like this:
if(users){ setUsers(userArray) }
QUESTION
I have the following map.jsx file in my react app, which displays a map on screen. I am trying to add a marker to this map (in a separate component called 'MyGreatPlace') which changes location every 2 seconds. It should just update the marker rather than refreshing the whole map, however i am getting the following error:
...ANSWER
Answered 2022-Feb-20 at 00:04That's not how you use the state objects. useState is for functional components, and you invoke it by providing two values. First, the reference to the actual value, and second - the reference to the setter. So const [stateVal, setStateVal] = useState()
gives you an undefined reference to a state object, and a reference to a function for updating it. You NEVER mutate the state directly (e.g. stateVal = newVal). You ALWAYS use the setter to mutate the state (which triggers a rerender). You can always initialize the value by passing a value into the useState()
call. Like this: setStateVal(newVal)

QUESTION
I cant deal with that problem. I got object locations. there are objects with info about position, function and icon color. I send it to Map. At start it shows ok but then when i filter the array and send new ones to show it doesnt render new ones. I add state to class and setState it- after check i see in console that everything is ok with changes- but markers are still the same. Please help
locations is also a state in parent stateless component.
Map Component
...ANSWER
Answered 2022-Jan-27 at 20:48setGoogleMapRef
is only called when the map component is instantiated I am guessing (you want this). so you need to access the map and update your locations in your render function outside of the setGoogleMapRef
callback.
something like the following:
QUESTION
Trying to build a locations near you webpage with react and google maps api. So far I'm able to fetch the API data using rapidapi (Trailapi) based on my location using an axios get request. Ive currently stored the list of hiking trails in my state and passed them over to my List component. When trying to display my new list in my placedetails component it throws a TypeError: places.map is not a function. The data was changed to an array which can be passed into .map but I'm still getting an error that the data passed in isnt the correct type in my List.js file.
Sample Response (Output of data when scanning for simple locations near me)
...ANSWER
Answered 2022-Jan-26 at 02:33First, you need to ensure that the places
is an Array if you wish to use map()
. It can be applied even to Array of Objects.
For example, in the snippet below, there's json data in jsonResponse
that you want to filter the data based on their height. You can try inputting numbers and filter that.

Answered 2021-Nov-05 at 18:54First of all you place same question twice. Please do not place same question twice. You can edit your previous question. The answer is same.
You are fetching a string value for lat or lng. But google map react support only number value. You have to convert string to number just. So change your code-
