New substitute for extending the extent in OpenLayers 4

I am currently in the process of migrating my code from OpenLayers 3 to OpenLayers 4 using TypeScript.

Previously, I had a code snippet that extended the extent of my map so that all vector shapes I drew would be visible upon loading...

angular.forEach(webMapValues.vectorFieldLayer, function (Field, key) 
{
webMapValues.mapObj.addLayer(Field);
webMapValues.extent = Field.getSource().getExtent();
webMapValues.totalExtent = ol.extent.extend(webMapValues.extent, 
webMapValues.totalExtent);
})

In the above snippet, the "ol.extent.extend" function worked like magic for me. However, in OpenLayers 4 with TypeScript, I have been struggling to find an equivalent method.

Any guidance or assistance on this matter would be highly appreciated!

Answer №1

It is my understanding that the function remains intact, albeit with a modified syntax:

import {combine} from 'ol/combine';

const largerRange = combine(range1, range2);

Answer №2

My current setup involves React, typescript, and OL4, and after some trial and error, I discovered this solution works perfectly for my needs:

import extent from 'ol/extent';

const mergedExtent = extent.extend(<layer1>,<layer2>);
