What kind of GeoJSON does OpenLayers use?
By default OpenLayers uses something they call a “spherical mercator” and without delving into the detail the geometry coordinates are represented by pixels on a 2D plane. Ideally, you would fix your GeoJSON to provide all coordinates in the same projection.
How to add feature to OpenLayers vector source?
Adding a feature to Openlayers Vector source 1 get the features from a vector source and 2 for some features, use their coordinates to construct new features, e.g. ol.geom.Circle buffers. More
How to retrieve the source features in OpenLayers?
For 1, to retrieve the source features, if I understand correctly you need to monitor the change event like this: If it is ‘ready’ you have asynchronously retrieved the source, correct?
How to add features outside of foreach in OpenLayers?
This creates a huge stack size, so something is clearly going wrong. Try to add features outside of forEach. Because features of the source are increasing every loop in your code. Try to code like this:
How to know if OpenLayers-get is not a function?
In my console I’m able to see the number of features and the value of them, so I know that there is no problem with the file. How I tried to do:
Is the grid code in GeoJSON a function?

The suggested solutions is actually more in line with recomendations than the code given in the actual OpenLayers examples that are linked. Namely, the __proto__ method is deprecated and the proper method for inheritance is by using Object.create ().
How to transform coordinates of feature in OpenLayers?
I want to transform the coordinates for an entire feature in openlayers. I have had success using ol.proj.transform to transform a single coordinate to a different projection, but is there any function that you can feed an entire feature, and all the coordinates within that feature will be transformed to the desired projection?
Which is the latest version of OpenLayers for client side raster?
This example uses OpenLayers v 6.6.1. The latest is v 6.6.0 . This example shows client-side raster reprojection capabilities from OSM (EPSG:3857) to arbitrary projection by searching in EPSG.io database.
