WFS-T prototype for LuciadRIA

Description

The wfststore package provides WFS-T capabilities to a LuciadRIA Application.

Implements

• Extends Get Capabilities to detect WFS-T
• Extends WFSFeatureStore to provide add, put, delete
• Extends WFSFeatureStore to provide getFeatureWithLock and LockFeature

The Main Components are:

• WFSTFeatureStore: a ready to use LuciadRIA Feature store capable to retrieve features add, put, delete features
• WFSTFeatureLockStore: a helper store to edit locked features

To build

This is the source code that produces a library delivered as a npm package. To build the source code use the npm scripts:

npm install
npm run build

Then you can publish the package to npm or other repository

To test

Some test have been added that runs using nodejs using Jest. No browser test is available at the moment. The test uses isomorphic-fetch to provide fetch in node testing with jest.

npm run test

Test use the sever-side implementations, use GeoServer of LuciadFusion

To install in your project

Simply import the NPM package into your project

npm install ria-wfststore

To use in your project

WFSTFeatureStore works as any other LuciadRIA Store that supports read/write. Therefore it is interchangeable with other stores.

You can use this store together with FeatureModel and Featurelayer.

To query the service capabilities

Normally you should start by interrogating the server to detect if WFS-T is supported, you can do this with WFSCapabilitiesExtended

WFSCapabilitiesExtended.fromURL(request, options).then(({wfsCapabilities, wfstCapabilities}: WFSCapabilitiesExtendedResult) => {
        const wfstCapable = wfstCapabilities.WFSTCapable;
        const wfstOperations = wfstCapabilities.WFSTOperations;
})
    .catch((err) => {
        handleHTTPErrors.handleError(err);
    });

Creating a simple WFS-T Store

• For this purpose use WFSTFeatureStore, then use it with 'FeatureModel' and Featurelayer and insert it to the map.
• You will need to wire to some Edit Controllers, you can refer to the LuciadRIA Create and Edit sample for that purpose.

const store = new WFSTFeatureStore({...options, serviceURL: "yoururl"});
const model = new FeatureModel(store, {reference: store.getReference()});
const layer = new FeatureLayer(mdoel, {labe: "My WFST", editable: true});

Creating a simple WFS-T Store

• For this purpose use WFSTFeatureLockStore

const store = new WFSTFeatureLockStore({...options, serviceURL: "yoururl"});
const model = new FeatureModel(store, {reference: store.getReference()});
const layer = new FeatureLayer(mdoel, {labe: "My WFST", editable: true});

Requirements

• LuciadRIA 2024.1 or higher (place it on a local npm repository for instance verdaccio )
• A ES6 or Typescript capable transpiler.
