Test client for OGC API Features and API Records

Basic test client for OGC API Features and API Records, based on Leaflet JS and jQuery. Just to show how to access an OGC API Features / Records implementation, to see if it provides data.

In a logging screen it shows the requests sent to the API, to understand what is happening.

This test client originated from an earlier experiment of the Dutch OpenGeoGroep on WFS 3 (OGC API - Features), see https://github.com/opengeogroep/wfs3-experiment/. It has been further developed during the OGC Code sprint in September 2022.

Scope

This client is work in progress and meant for just a basic demo / test to access an oapi-features implementation. No more than that (so it is not a full client on OGC API Features / Records for example).

Prerequisites of an API implementation

• support OGC API Features core or OGC API Records DRAFT including "free text search" using the q parameter
• support Cross-origin resource sharing (CORS-enabled API), (tip: see https://enable-cors.org/ )
• support GeoJSON as encoding of data (features or records)
• OpenAPI description of the service

Limitations

The live version on github.io has limitations:

• only support APIs using https (secured connections): because of blocking mixed content in browsers, github.io is running on https, the API also must support https connections
