I'm trying to to use the OpenLayers in my Yii2 Project, but i don't know thow to use the "import" syntax in JS based on this example OpenLayers Example

my asset file:

I have two react components namely Dashboard and singleFeature.In the dashboard I have an ionRangleSlider which takes value from redux state. And I'm rendering the singleFeature component inside the Dashboard. SingleFeature component creates a fetch network request and updates the redux state using the dispatch method.

And the ionRangeSlider which resides inside the Dashboard takes value from the redux state which gets updated by singleFeature component. But regardless of whatever I have tried it's not reflecting the ionRangeSlider. However I can see the redux state is getting updated but not reflecting in any of the component.

Codes:

Dashboard.js

I've a ToysPage.js with a class component and a SearchFeature.js with a functional component (child of ToysPage). I made a searchBar in SearchFeature.js with hooks and with console.log I can see that it works. But how can I pass the const filteredToys to the state toysFiltered in ToysPage.js?

ToysPage.js

I solved this during the writing of the question and have provided my answer below since it was a bit tricky to work out. I am happy to hear any better or alternative answers.

I have an Angular OpenLayers 6 geomapping app. Being Angular I use Typescript and it transpiles and runs fine. And also being Angular it uses ng test to do the testing. All tests run fine.

However I use mocha + chai for testing in the IDE (IntelliJ) since I don't require UI testing for the mathematical work I'm currently performing (ng test runs the UI tests if and when I need that. But in the IDE I select the tests to run). Testing this way worked fine until I added a new test that creates a new instance of a class that imports GeoJSON:

So I just downloaded the "VSCode Cucumber (Gherkin) Full Language Support + Formatting + Autocomplete" plugin to help with cucumber formatting inside my vscode editor. It seems like from their documentation, the "VSCode Cucumber (Gherkin)..." plugin supports a feature which will let you see the relationship between feature files, step definitions, and page objects via hovering over the corresponding text in the .feature file.

However, the "VSCode Cucumber (Gherkin)..." plugins' documentation on path mapping between files is light. Does anyone know how you would create the desired syntax linking between feature files, step-definitions, and page-objects given the following directory structure?

I am working on an openlayers map to add a vector layer with the source of the local geojson and gpx file in a Vuejs project, but the vector layer cannot be displayed. I tested outside of Vue.js and I have the same problem.

Voici le code :

Following exactly the example of the openlayers site in:

https://openlayers.org/en/latest/examples/box-selection.html?q=feature

Locally I have the following error:

In OpenLayers 5.3.0, I've created a MultiPolygon using the 'difference' tool in turf.js. The turf.js MultiPolygon looks fine when I examine the JSON, but when I try to use that to create a feature in OpenLayers, I get "Uncaught TypeError: t.addEventListener is not a function".

I've tried many combinations of JSON.stringify, JSON.parse, GeoJSON.readFeatures, .getCoordinates()... I tried adding the turf.js MultiPolygon as a feature directly via source.addFeature(multiPolygonGeometry), but then I get 'Uncaught TypeError: e.getId is not a function'. I also tried source.addFeatures(multiPolygonGeometry) (note the plural 'addFeatures'), and that didn't give me any errors, but also didn't appear to add anything to the source.

Relevant lines in my code are as follows:

I am creating a Point feature, like this:
