This isn't how JSX works. It isn't redirecting because the function can't return renderable JSX nor does it try to navigate. Everything that is rendered needs to be in the
render function, or functional component return. This handler doesn't return anything.
You can either declaratively conditionally render a
Redirect component, or imperatively issue a navigation action.
Redirectcomponent on condition.
The map renders and the color fill happens too, but only when a mouse enter event happens. How do I trigger it on load? I am using react-simple-maps, the JSON data is valid as it loads the map when mouse enters. Here is the source code - Github...

I would try to extend interface. You can't change the type of existing property. Something like this below. Let me know if it works. Also check this out it's about modifying existing types Overriding interface property type defined in Typescript d.ts file
I'm trying to copy what is done in this example (except making it in one file rather than 2):
I'm getting everything to work, except the map renders upside down.
- using a projection (d3-geo.geoEqualEarth) in the hopes that the map will receive its orientation from the projection
- changing projectionConfig scale and rotation in the hopes that any of those might change how the map is rendered
- modifying topojson file found at the link and changing its "transform" property
- (Note: I encountered a separate issue which I felt wasn't as relevant since this issue should be resolved without having to modify the original topojson file. Passing a filepath to resulted in a XHTTPRequest)
- removing non-essential components such as ZoomableGroup
- modifying the css

react-simple-maps version from example,its "1.0.0-beta.0"
The code is working with the property 'name', names appear correctly on the map.

I added a state 'countries' which will be initialized with json file converted in object. I fetch data from my sql database and then I set the state 'countries' with data I wanted to add.

According to the docs
The reducer is a pure function that takes the previous state and an action, and returns the next state.
You can then see that it's because you are breaking out of your switch statement rather than returning the new state in
DashboardReducer.js. It should instead look something like this:
I am following the guide for react-simple-maps npm documentation to get a map up and running so I can have a play with it.
The code sample I am using is from the usage section at the following link:
The issue I have is with the topojson file loading:...
ANSWERAnswered 2017-Nov-22 at 20:24
When loading topojson files using
geographyUrl in the create-react-app environment, you have to place it in the public folder. If you place world-50m.json directly in public (
./public/world-50m.json), this should do the trick:
