Library to display a map and live track the position of the bus for a specific trip.
This lib runs in the browser and can be included in any site.
- An account with the premium feature enabled and configured.
- The scanner app (v7.13.0 or higher) installed on an Android phone to capture the location of the bus.
- A Betterez public API key.
- You will need to select a map tiles provider, that is, a provider for the map imagery.
This lib is built on top of leaftlet so you will need to install leaflet 1.7.1 or compatible.
Two options:
- Include the scripts in you HTML file, or
- via npm install (if using NodeJS)
- Include Leaflet CSS file in the head section of your document:
<link rel="stylesheet" href="https://unpkg.com/leaflet@1.7.1/dist/leaflet.css"
integrity="sha512-xodZBNTC5n17Xt2atTPuE1HxjVMSvLVW9ocqUKLsCC5CXdbqCmblAshOMAS6/keqq/sMZMZ19scR4PsZChSR7A=="
crossorigin=""/>
- Include Leaflet JavaScript file after Leaflet’s CSS:
<!-- Make sure you put this AFTER Leaflet's CSS -->
<script src="https://unpkg.com/leaflet@1.7.1/dist/leaflet.js"
integrity="sha512-XQoYMqMTK8LvdxXYG3nZ448hOEQiglfqkJs1NOQV44cWnUrBc8PkAOcXy20w0vlaXaVUearIOBhiXZ5V3ynxwA=="
crossorigin=""></script>
- Include btrz-map:
<!-- Make sure you put this AFTER Leaflet's JS -->
<script type='text/javascript' src="https://unpkg.com/btrz-map@0.1.1/dist/btrz-map.js"></script>
npm i btrz-map leaflet@1.7.1
With this method you will need to configure your server to find the proper files for each lib.
For btrz-lib, all the files you need are located under node_modules/btrz-map/dist
For leaflet, all the files you need are located under node_modules/leaflet/dist

// Select the map tiles provider of your choice for the map imagery (e.g Mapbox, Carto, etc)
// Beware that when using a map tiles they ask you to include the an attribution text on the map.
// Also most providers offers a free tier, but if you expect a high load you might need to create an account with them
// Check the provider site for more info.
// In this example we are using Carto as a map tiles provider.

.then((_trip) => {

});
/* trip includes the folowing props for convenience
trip.routeId
trip.scheduleId
trip.scheduleName
trip.departureTimestamp
trip.stations
and each station includes:
station.id
station.name
station.departureTimestamp
station.arrivalTimestamp
station.latitude
station.longitude
station.positionInTrip
*/
// ..after you are done with the map, remove the trip from the map to free resources.
// map.removeTrip();
// Optional: All times are showed in local timezone, it is recommended to make it clear somewhere in the page/
const timezoneDiv = document.getElementById("timezoneNote");
timezoneDiv.innerHTML = "All times are in " + Intl.DateTimeFormat().resolvedOptions().timeZone + " time";
</script>Note: Only one trip at a time is allowed on the map.
