Resources

• OJP Demo App: https://opentdatach.github.io/ojp-demo-app/ - web application using this SDK
• CHANGELOG for latest changes
• npm ojp-sdk package: https://www.npmjs.com/package/ojp-sdk

Usage

• get an API key from opentransportdata.swiss API manager

• include ojp-sdk, ojp-shared-types packages in the ./package.json dependencies of the project

  "dependencies": {
    "ojp-shared-types": "0.1.5",
    "ojp-sdk": "0.22.1",
  }

• use the SDK, see also playground.component.ts in examples

import * as OJP from 'ojp-sdk-next';

// ...

// declare the stage config, PROD example below
const httpConfig: OJP.HTTPConfig = {
  url: 'https://api.opentransportdata.swiss/ojp20',
  authToken: 'TOKEN_FROM_opentransportdata.swiss',
};

// define a requestorRef that describes the client
const requestorRef = 'MyExampleTransportApp.v1';

// create the SDK
const language = 'de'; // de, fr, it, en
const ojpSDK = OJP.SDK.create(requestorRef, httpConfig, language);

// build LIR by Name
const searchTerm = 'Bern';
const request1 = ojpSDK.requests.LocationInformationRequest.initWithLocationName('Bern');

// build LIR by StopRef
const stopRef = '8507000'; // Bern
const request2 = ojpSDK.requests.LocationInformationRequest.initWithPlaceRef(stopRef);

// build LIR by BBOX
// these are equivalent
let bbox: string | number[] = '7.433259,46.937798,7.475252,46.954805';
bbox = [7.433259, 46.937798, 7.475252, 46.954805];

const request3 =  ojpSDK.requests.LocationInformationRequest.initWithBBOX(bbox, ['stop']);

// change XML payload if needed
request1.payload.initialInput ...

// fetch the results
async myMethod() {
  // ...
  const response = await request1.fetchResponse(ojpSDK);

  if (!response.ok) {
    // handle error
    console.log(response.error);
    return;
  }

  // do something with the value
  const placeResults = response.value.placeResult ?? [];
  placeResults.forEach(placeResult => {
    console.log(placeResult.place.name);
  });
}
