Built-in templates used for html generation

HTML Templates¶

To override an OGC API Features template:

Create a directory ogc/features in the location you wish to override:
- GEOSERVER_DATA_DIR/templates/ogc/features
- GEOSERVER_DATA_DIR/workspace/workspace/ogc/features
- GEOSERVER_DATA_DIR/workspace/workspace/datastore/ogc/features
- GEOSERVER_DATA_DIR/workspace/workspace/datastore/featuretype/ogc/features
Create a file in this location, using the GeoServer 2.19-SNAPSHOT examples below:
The above built-in examples are for GeoServer 2.19-SNAPSHOT, please check for any changes when upgrading GeoServer.

As an example ogc/features/collections.ftl is used to list published collection:

<#global pagecrumbs="<li class='breadcrumb-item'><a href='"+serviceLink("")+"'>Home</a></li><li class='breadcrumb-item active'>Collections</li>">
<#include "common-header.ftl">

  <h1>GeoServer Feature Collections</h1>
  <p class="my-4">
    This document lists all the collections available in the Features service.<br/>
    This document is also available as <#list model.getLinksExcept(null, "text/html") as link><a href="${link.href}">${link.type}</a><#if link_has_next>, </#if></#list>.
  </p>
  
  <div class="row">
    <#list model.collections as collection>
    <div class="col-xs-12 col-md-6 col-lg-4 pb-4">
      <div class="card h-100">
        <div class="card-header">
          <h2><a href="${serviceLink("collections/${collection.id}")}">${collection.id}</a></h2>
        </div>
        <#include "collection_include.ftl">
      </div>
    </div>
    </#list>
  </div>

<#include "common-footer.ftl">

Save file to GEOSERVER_DATA_DIR/workspace/templates/ogc/collections.ftl, and rewrite as:

<#include "common-header.ftl">
       <h2>OGC API Feature Collections</h2>
       <p>List of collections published.</p>
       <p>See also: <#list model.getLinksExcept(null, "text/html") as link>
          <a href="${link.href}">${link.type}</a><#if link_has_next>, </#if></#list>.</p>

     <#list model.collections as collection>
       <h2><a href="${serviceLink("collections/${collection.id}")}">${collection.id}</a></h2>
       <#include "collection_include.ftl">
     </#list>
<#include "common-footer.ftl">

A restart is required, as templates are cached.

template collections.ftl override applied¶

Language codes are appended for internationalization. For French create the file GEOSERVER_DATA_DIR/workspace/workspace/ogc/collections_fr.ftl and translate contents:

<#include "common-header.ftl">
       <h2>OGC API Feature Service</h2>
       <p>Liste des collections publiées.</p>
       <p>Voir également: <#list model.getLinksExcept(null, "text/html") as link>
          <a href="${link.href}">${link.type}</a><#if link_has_next>, </#if></#list>.</p>

     <#list model.collections as collection>
       <h2><a href="${serviceLink("collections/${collection.id}")}">${collection.id}</a></h2>
       <#include "collection_include.ftl">
     </#list>
<#include "common-footer.ftl">
