Awesome native OpenGL-owered maps - by Mapbox
- you want full map styling capability to match the uses of your app (example: downplaying highways for a running app),
- you want a platform independent map implementation,
- you care about performance so you don't want a web based solution,
- you want an open source map implementation that you can tweak yourself,
- you want to leverage Mapbox's backend to visualize massive geo data sets,
- you want advanced analytics about your app's users.
NativeScript 1.3.0 (tns --version) is required for smooth installation, so please upgrade if you need to.
You need a Mapbox API access token (they have a free Starter plan!), so sign up with Mapbox. Once you've registered go to your Account > Apps > New token. The 'Default Secret Token' is what you'll need.
From the command prompt go to your app's root folder and execute:
tns plugin add nativescript-mapbox
If you get an error during iOS build related to Podspec versions, probably the easiest fix is: tns platform remove ios and tns platform add ios.
If you want a quickstart, clone our demo app. And here's the comprehensive list of supported functions:
var mapbox = require("nativescript-mapbox");
mapbox.show({
accessToken: 'YOUR_API_ACCESS_TOKEN', // see 'Prerequisites' above
style: 'emerald', // light|dark|emerald|satellite|streets , default 'streets' (there is also 'hybrid' for Android)
margins: {
left: 40, // default 0
right: 40, // default 0
top: 450, // default 0
bottom: 40 // default 0
},
center: { // optional without a default
lat: 52.3702160,
lng: 4.8951680
},
zoomLevel: 9.25, // 0-20, default 0
showUserLocation: true, // default false - requires location permissions on Android which you can remove from AndroidManifest.xml if you don't need them
hideAttribution: false, // default false, Mapbox requires this default if you're on a free plan
hideLogo: false, // default false, Mapbox requires this default if you're on a free plan
hideCompass: false, // default false
disableRotation: false, // default false
disableScroll: false, // default false
disableZoom: false, // default false
markers: [ // optional without a default
{
'lat': 52.3732160, // mandatory
'lng': 4.8941680, // mandatory
'title': 'Nice location', // recommended to pass in
'subtitle': 'Really really nice location' // one line is available on iOS, multiple on Android
}
]
}).then(
function(result) {
console.log("Mapbox show done");
},
function(error) {
console.log("mapbox show error: " + error);
}
)All further examples assume mapbox has been required. Also, all functions support promises, but we're leaving out the .then() stuff for brevity where it doesn't add value.
mapbox.hide() mapbox.addMarkers([
{
'lat': 52.3602160, // mandatory
'lng': 4.8891680, // mandatory
'title': 'One-line title here', // no popup unless set
'subtitle': 'Infamous subtitle!'
},
{
..
}
]) mapbox.setCenter(
{
lat: 52.3602160, // mandatory
lng: 4.8891680, // mandatory
animated: false // default true
}
)Here the promise callback makes sense, so adding it to the example:
mapbox.getCenter().then(
function(result) {
console.log("Mapbox getCenter done, result: " + JSON.stringify(result));
},
function(error) {
console.log("mapbox getCenter error: " + error);
}
) mapbox.setZoomLevel(
{
level: 6.5, // mandatory, 0-20
animated: true // default true
}
) mapbox.getZoomLevel().then(
function(result) {
console.log("Mapbox getZoomLevel done, result: " + JSON.stringify(result));
},
function(error) {
console.log("mapbox getZoomLevel error: " + error);
}
) // this is a boring triangle drawn near Amsterdam Central Station
mapbox.animateCamera({
// this is where we animate to
target: {
lat: 52.3732160,
lng: 4.8941680,
},
zoomLevel: 17, // Android
altitude: 2000, // iOS (meters from the ground)
bearing: 270, // Where the camera is pointing, 0-360 (degrees)
tilt: 50,
duration: 10 // in seconds
}) mapbox.setTilt(
{
pitch: 35, // default 30 (degrees angle)
duration: 4000 // default 5000 (milliseconds)
}
) mapbox.getTilt().then(
function(tilt) {
console.log("Current map tilt: " + tilt);
}
)Draw a shape (like a line/route, or star). Just connect the dots like we did as a child. The first person to tweet a snowman drawn with this function gets a T-shirt.
// this is a boring triangle drawn near Amsterdam Central Station
mapbox.addPolygon({
points: [
{
'lat': 52.3832160, // mandatory
'lng': 4.8991680 // mandatory
},
{
'lat': 52.3632160,
'lng': 4.9011680
},
{
'lat': 52.3932160,
'lng': 4.8911680
}
]
})Draw a polyline. Connect the points given as parameters.
// Draw a two segment line near Amsterdam Central Station
mapbox.addPolyline({
color: 0xff29a025, //Set the color of the line (default black)
width: 7, //Set the width of the line (default 5)
points: [
{
'lat': 52.3833160, // mandatory
'lng': 4.8991780 // mandatory
},
{
'lat': 52.3834160,
'lng': 4.8991880
},
{
'lat': 52.3835160,
'lng': 4.8991980
}
]
});On Android 6 you need to request permission to be able to show the user's position on the map at runtime when targeting API level 23+. Even if the uses-permission tag for ACCESS_FINE_LOCATION is present in AndroidManifest.xml.
Note that hasFineLocationPermission will return true when:
- You're running this on iOS, or
- You're targeting an API level lower than 23, or
- You're using Android < 6, or
- You've already granted permission.
mapbox.hasFineLocationPermission().then(
function(granted) {
// if this is 'false' you probably want to call 'requestFineLocationPermission' now
console.log("Has Location Permission? " + granted);
}
);
// if no permission was granted previously this will open a user consent screen
mapbox.requestFineLocationPermission().then(
function() {
console.log("Location permission requested");
}
);Note that the show function will also check for permission if you passed in showUserLocation : true. If you didn't request permission before showing the map, and permission was needed, then the location is not drawn on the map and the plugin will log an error to the console.
