Example of making a WFS GetFeature request with a filter.

This example generates a GetFeature request which uses a PropertyIsEqualTo and a PropertyIsLike filter, and then posts the request to load the features that match the query.

import 'ol/ol.css';
import Map from 'ol/Map';
import VectorSource from 'ol/source/Vector';
import View from 'ol/View';
import XYZ from 'ol/source/XYZ';
import {GeoJSON, WFS} from 'ol/format';
import {Stroke, Style} from 'ol/style';
import {Tile as TileLayer, Vector as VectorLayer} from 'ol/layer';
import {
  and as andFilter,
  equalTo as equalToFilter,
  like as likeFilter,
} from 'ol/format/filter';

var vectorSource = new VectorSource();
var vector = new VectorLayer({
  source: vectorSource,
  style: new Style({
    stroke: new Stroke({
      color: 'rgba(0, 0, 255, 1.0)',
      width: 2,

    maxZoom: 20,

var map = new Map({
  layers: [raster, vector],
  target: document.getElementById('map'),

    zoom: 12,

// generate a GetFeature request
var featureRequest = new WFS().writeGetFeature({
  srsName: 'EPSG:3857',
  featureNS: 'http://openstreemap.org',

  featureTypes: ['water_areas'],
  outputFormat: 'application/json',
  filter: andFilter(
    likeFilter('name', 'Mississippi*'),
    equalToFilter('waterway', 'riverbank')

// then post the request and add the received features to a layer
fetch('https://ahocevar.com/geoserver/wfs', {
  method: 'POST',
  body: new XMLSerializer().serializeToString(featureRequest),
  .then(function (response) {
    return response.json();
  .then(function (json) {
    var features = new GeoJSON().readFeatures(json);
