This is a mirror of the official Västtrafik Travel Planner API Client for Javascript. For more information, see the official api website.

Usage

NodeJS (see ./example.js)

const Api = require('vasttrafik-api');

// Sample credentials. Be sure to get your own before going into production.
(async () => {
    const key = '8aOzt2RmMIG0OXSyIgjM2IkHvAoa';
    const secret = 'OMxjxjaXblXdpn8E1gYFehHyx3Ea';
    await vasttrafik.authorize(key, secret);
    
    const api = new vasttrafik.LocationApi();
    const res = await api.getLocationByName({input: 'Lindholmen'});
    console.log(res.text);
})();

Browsers (see ./example.html)

<script src="./dist/vasttrafik.js"></script>
<script>
    (function() {
        // Sample token. Generate access token on server (see example.js)
        var token = 'b94ad16c-715c-3820-a321-503b0267346e';
        vasttrafik.setAccessToken(token);

        var api = new vasttrafik.LocationApi();
        api.getLocationByName({input: 'Lindholmen'}, function (error, data, res) {
            console.log(res.text);
        });

Authentication

If you just want to test things out you can use these sample credentials:

key '8aOzt2RmMIG0OXSyIgjM2IkHvAoa' secret 'OMxjxjaXblXdpn8E1gYFehHyx3Ea'

Don't forget to create your own credentials in the developer portal before going into production however since the sample ones might become invalid at any time.

Changes

This repository is mostly a simple mirror of the official api client, but a few changes were made to make it easier to work with.

Helper methods added:

• client.authorize(key, secret, deviceId) Fetches an access token with the specified key and secret and then authorizes the client with the it (cannot be used in the browser)
• client.setAccessToken(token) Authorizes upcoming api calls with the specified access token

Monkey patches:

• JSON instead of XML is returned by default (see mirror/src/ApiClient.js#448)
• Avoids duplicate api calls when using promises (see mirror/src/ApiClient.js#453)

Version

• npm version patch|minor|major
• npm run deploy
