Migrate from version 4 - the Services library

Overview of the tutorial

This tutorial covers basic use cases to help you switch our services. For example, switching the Routing API or Search API services from version 4 of the Maps SDK for Web to our new version. We will use code examples to explain the main differences between the SDKs. In the new SDK, ** services** are not part of the map library. We now provide a separate library to only include services.

Prerequisites

To start using the latest version of TomTom Maps SDK for Web you need the following:

The Services library
The Maps SDK for Web can be used in three ways:
- Downloaded from NPM: https://www.npmjs.com/package/@tomtom-international/web-sdk-services
- With a CDN: https://api.tomtom.com/maps-sdk-for-web/cdn/6.x/&ltversion>/services/services-web.min.js
  - NOTE: include the latest version in the URL.
- Downloaded from here: Downloads.
  In this tutorial, we are using a CDN as an example.
API Key - If you don’t have an API Key visit the How to get a TomTom API Key site and create one.
Add the following to the <head> element of your HTML document:
```
1

2
<script src="https://api.tomtom.com/maps-sdk-for-web/cdn/6.x/<version>/services/services-web.min.js"></script>
```
Maps and services use the same namespace and will automatically attach themselves to the tt object. Services will be accessible using tt.services.

Displaying a route/directions

Here we have the code to display a route from point A to point B on the map.

Version 4 of the Maps SDK for Web

1
tomtom
2
  .routing()
3
  .key("<your-api-key>")
4
  .locations("37.7683909618184,-122.51089453697205:37.769167,-122.478468")
5
  .go()
6
  .then(function (routeJson) {
7
    var route = tomtom.L.geoJson(routeJson, {
8
      style: { color: "#00d7ff", opacity: 0.6, weight: 6 },
9
    }).addTo(map)
10
    map.fitBounds(route.getBounds(), { padding: [5, 5] })
11
  })

Latest version of the Maps SDK for Web

1
tt.services
2
  .calculateRoute({
3
    key: "<your-api-key>",
4
    locations: "-122.510601,37.768014:-122.478468,37.769167",
5
  })
6
  .then(function (response) {
7
    var geojson = response.toGeoJson()
8
    map.addLayer({
9
      id: "route",
10
      type: "line",
11
      source: {
12
        type: "geojson",
13
        data: geojson,
14
      },
15
      paint: {
16
        "line-color": "#00d7ff",
17
        "line-width": 8,
18
      },
19
    })
20
    var bounds = new tt.LngLatBounds()
21
    geojson.features[0].geometry.coordinates.forEach(function (point) {
22
      bounds.extend(tt.LngLat.convert(point))
23
    })
24
    map.fitBounds(bounds, { padding: 20 })
25
  })

Performing a fuzzy search

Version 4 of the Maps SDK for Web

1
tomtom
2
  .fuzzySearch()
3
  .key("<your-api-key>")
4
  .query("pizza")
5
  .go()
6
  .then(function (result) {
7
    console.log(result)
8
  })

Latest version of the Maps SDK for Web

1
tt.services
2
  .fuzzySearch({
3
    key: "<your-api-key>",
4
    query: "pizza",
5
  })
6
  .then(function (result) {
7
    console.log(result)
8
  })

Differences in APIs

Here is an overview of some of the most important updates within our top-level namespace.

Common factory functions renamed

Some of the common functions changed. Here are some examples:

Version 4	Current version
tomtom.key(key, [value])	You need to pass the API Key directly to the service. 1 `tt.services.fuzzySearch({key: API-KEY, ...});`
tomtom.localeService()	You need to pass the language directly to the service. For the map, you can also change the language after initialization by doing: 1 `map.setLanguage('en');`

The following table lists the services from the version 4 of the SDK and their equivalents in the latest one.

Version 4	Current version
tomtom.additionalData()	tt.services.additionalData()
tomtom.alongRouteSearch()	tt.services.alongRouteSearch()
No equivalent	tt.services.autocomplete()
tomtom.reachableRange()	tt.services.calculateReachableRange()
tomtom.routing()	tt.services.calculateRoute()
tomtom.categorySearch()	tt.services.categorySearch()
tomtom.copyright()	tt.services.copyrights()
