How to display, center and zoom a map using OpenLayers?

Question

I started learning the OpenLayers and GeoServer. The layer is added at GeoServer using the OSM shape file which is indicated as EPSG:4326 with bounds [68.5094575, 6.6791812, 97.0315678, 35.3123975]. Using OpenLayers this layer is obtained as WMS and getting displayed.

For displaying the map the following line of code is used:

map.getView().fit(bounds, map.getSize());

Now the map is getting displayed. But when I use the below code, the map is not getting displayed:

map.getView().fit(bounds, map.getSize());
map.getView().setCenter(ol.proj.transform[77.216574, 28.627671], 'EPSG:4326', 'EPSG:3857'));
map.getView().setZoom(5);

Thanks in advance.

What is bounds? Is it the array [68.5094575, 6.6791812, 97.0315678, 35.3123975]? — geocodezip

You have a syntax error:

map.getView().setCenter(ol.proj.transform[77.216574, 28.627671], 'EPSG:4326', 'EPSG:3857'));

should be:

map.getView().setCenter(ol.proj.transform([77.216574, 28.627671], 'EPSG:4326', 'EPSG:3857'));

If I change that and remove the map.getView().fit(bounds, map.getSize());

The map works:

html,
body {
  height: 100%;
  width: 100%;
  padding: 0px;
  margin: 0px;
}

.map {
  height: 95%;
  width: 100%;
}

      })
    ],
    target: 'map',
    view: new ol.View()
  });
  map.getView().setCenter(ol.proj.transform([77.216574, 28.627671], 'EPSG:4326', 'EPSG:3857'));
  map.getView().setZoom(5);
