To make web maps, GeoServer is often used to take vector data and render it to Web Map Service tiled images. Your OpenLayers 3 JavaScript client consumes these WMS tiles and displays them on the map. In this use-case, the JavaScript never sees vector data, only images (typically PNG). This is server-side map rendering.
What is your source data geometry type? Polygons, linestrings, or points? Do you want it rendered to web map service tiles by GeoServer? OpenLayers can also consume vector data. Please tell us what you are trying to do. This will determine whether you should be using GeoServer to deliver vector data (e.g. via WFS) or image data (e.g via WMS).
The url parameter is the "service endpoint". For local testing you might use for WMS:
url: "http://localhost:8080/geoserver/wms"
When you have deployed your GeoServer instance on a web server (for example services.example.org) you might change this to:
url: "http://services.example.org/geoserver/wms"
but this is dependent on server configuration. For WMS, it is your GeoServer web app context plus "/wms".
All together in OpenLayers 3 you can define a tiled WMS layer with something like:
new ol.layer.Tile({
source: new ol.source.TileWMS({
url: "http://services.example.org/geoserver/wms",
params: {
"layers": "myns:mylayer",
"tiled": true
},
serverType: "geoserver"
})
})
The above goes inside a statement like
new ol.Map({
target: "map",
layers: [
[...]
Kind regards,

I am trying to follow the example of this link because I want to add vector
data (which I have uploaded onto Geoserver) in the map:
https://github.com/walkermatt/ol3-layerswitcher/blob/master/examples/layerswitcher.js
<https://github.com/walkermatt/ol3-layerswitcher/blob/master/examples/layerswitcher.js>
I am unsure about this part:
url: 'http://demo.opengeo.org/geoserver/wms’,
How can I find out what is my source url?
Also, since it is vector data, do I use these two:
new ol.layer.Vector
source: new ol.source.Vector
