# Migration SDK

The Radar Maps Migration SDK allows you to easily convert your Google Maps web implementations with Radar Maps by simply swapping the script import tag.

## How it works

The Google maps import will look like one of the following:

**Direct src import**

```html theme={null}
<script
  async
  src="https://maps.googleapis.com/maps/api/js?key=YOUR_API_KEY&loading=async&callback=initMap"
>
</script>
```

**Dynamic Library import**

```html theme={null}
<script>
  (g=>{var h,a,k,p="The Google Maps JavaScript API",c="google",l="importLibrary",q="__ib__",m=document,b=window;b=b[c]||(b[c]={});var d=b.maps||(b.maps={}),r=new Set,e=new URLSearchParams,u=()=>h||(h=new Promise(async(f,n)=>{await (a=m.createElement("script"));e.set("libraries",[...r]+"");for(k in g)e.set(k.replace(/[A-Z](/g,t=>"_"+t[0].toLowerCase()),g[k]);e.set("callback",c+".maps."+q);a.src=`https://maps.${c}apis.com/maps/api/js?`+e;d[q]=f;a.onerror=()=>h=n(Error(p+" could not load."));a.nonce=m.querySelector("script[nonce]")?.nonce||"";m.head.append(a)}));d[l]?console.warn(p+" only loads once. Ignoring:",g):d[l]=(f,...n)=>r.add(f)&&u().then(()=>d[l](f,...n))})({
    key: "YOUR_API_KEY",
    v: "weekly",
    // Use the 'v' parameter to indicate the version to use (weekly, beta, alpha, etc.).
    // Add other bootstrap parameters as needed, using camel case.
  });
</script>
```

For either of these imports, simply replace these lines with the Radar Migration SDK script. Now without any further changes to the code, calls to the Google Maps API will now be made to Radar's API.

```html theme={null}
<script src="https://js.radar.com/v1/radar-migration-sdk.js?key=RADAR_PUBLISHABLE_KEY"></script>
```

Additionally you can specify a callback and Radar map style which is defined below.
