Example of a view with a constrained extent.
This map has a view that is constrained in an extent. This is done using the extent
view option. Please note that specifying constrainOnlyCenter: true
would only apply the extent restriction to the view center.
import Map from 'ol/Map.js';
import OSM from 'ol/source/OSM.js';
import TileLayer from 'ol/layer/Tile.js';
import View from 'ol/View.js';
import ZoomSlider from 'ol/control/ZoomSlider.js';
import {defaults as defaultControls} from 'ol/control.js';
const view = new View({
center: [328627.563458, 5921296.662223],
zoom: 8,
extent: [-572513.341856, 5211017.966314, 916327.095083, 6636950.728974],

new TileLayer({
source: new OSM(),

],
