React Mapkit 🗺️


$3

This project is still in development and is missing features (including being able to place anything other than markers on a map). Contributions are welcome!

See the demo storybook!

Install

yarn add react-mapkit

$3

This package includes a script you can use to generate a JWT token.

At the moment this only work if you've run yarn within the package folder and run the script from within react-mapkit. This should be fixed (https://github.com/chrisdrackett/react-mapkit/issues/14)

First add your private key from Apple to the tokengen folder with the name key.p8 then run:

node tokengen

Follow the prompts. The generated token can then be used for your app. If you want to generate short lived tokens you can refer to the script in tokengen to get an idea of how to do this in node.

Storybook

This project contains a storybook that shows examples of how the component can be used. To use this storybook follow these steps:

1. copy devToken.ts.rename to devToken.ts
2. add a valid token from tokengen (see above) or similar to devToken.ts
3. run yarn then yarn storybook
4. visit the URL storybook gives you
5. play with maps!

Use

React Mapkit can be used a couple different ways. No matter what method you use, you'll need to use a token or callback. Refer to https://developer.apple.com/documentation/mapkitjs/mapkit/2974045-init for info about using a server and callback or use the tokengen script included in this package to create your own token.

Now on to the various ways to use this lib:

$3

This is probably the simplest way to use react-mapkit. This method works if you just want to render a single map and don't need to manipulate it (other than placing markers) via. code.

When using the Map component alone you'll need to provide the tokenOrCallback prop.

``js
import { Map, Marker } from 'react-mapkit'

const MapAlone = () => (

)
`

$3

The second way to use react-mapkit is by having a provider. This method is useful if you plan on having more than one map in your app and don't want to have a tokenOrCallback prop on all of them. I suggest putting the MapkitProvider at the top of your app so it only loads once. Loading it twice can cause errors.

You can also optionally set the maps language using language. Refer to: https://developer.apple.com/documentation/mapkitjs/mapkitinitoptions/2978217-language

`js
import { MapkitProvider, Map, Marker } from 'react-mapkit'

const MapWithProvider = () => (
} language={}>


)
`

$3

This is the most powerful way to use this library as it gives you full access to both mapkit and the map. This lets you do anything that mapkit supports even if this library does not yet support it. This method is similar to the above as you are using both the MapkitProvider and Map components, but you'll also use the useMap hook to get access to the map instance.

useMap provides the following:

- mapkit: the mapkit library itself
- map: the instance of a map
- mapProps: a set of props you'll need to spread onto a Map component to create a map.
- setVisibleMapRect, setRegion, setCenter, setRotation: convinance functions to manipulate the map. More coming soon!

`js
import { MapkitProvider, Map, useMap, Marker } from 'react-mapkit'

const UseMapExample = () => {
const { map, mapProps, setRotation } = useMap()

return (
<>
map.setRotationAnimated(50)}>rotate to 50deg!
setRotation(50)}>same as the above, but using the react-mapkit provided function.


const MapWithUseMap = () => (
}>


)
`

Notes on various components / hooks

$3

Both the Map component and the useMap hook can take default map options. for map these are passed as props. For example the following sets a custom center for the map:

`js
`

To do the same with useMap you would do:

`js
const { map } = useMap({ center: [37.415, -122.048333] })
`

The available options can be found here: https://developer.apple.com/documentation/mapkitjs/mapconstructoroptions

Note that some of these have been simplified so you don't need to use mapkit constructors. For example, instead of having to pass create a coordinate via new mapkit.Coordinate(37.415, -122.048333) to supply to center you just pass [37.415, -122.048333]`.
