I built an address search function using Amplify Geo and MapLibre GL Geocoder 🎉
Amplify Geo was officially released the other day. Amplify Geo is one of the features of AWS Amplify that makes it easier to build Amazon Location Service.
In this article, I tried to build a map application by adding an address search function with MapLibre GL Geocoder.
Advance Preparation
- Amplify Geo settings up to the map display function
Building a Map Application with Amplify Geo and Vue.js
Setting up Amplify Geo
First, we will configure Amplify Geo.
Add location feature (geocoding)
If you only need a location function (geocoding), you can implement it with these two commands and the map function!
Amazon Location Service requires AWS console configuration and role configuration, but Amplify Geo does all of that for you!
amplify add geo
amplify push
This completes the configuration of Amplify Geo.
Frontend
Next, let's build the actual map application.
Once you have configured the map display function of Amplify Geo, you only need to change "MapPane.vue" and "main.js".
execution environment
- node v16.10.0
- npm v7.24.0
Install MapLibre GL Geocoder in advance.
npm install @maplibre/maplibre-gl-geocoder

Load MapLibre GL Geocoder and wrappers.

import { createMap, createAmplifyGeocoder } from 'maplibre-gl-js-amplify';
export default {

this.mapCreate();
},

mapCreate: async function() {
const map = await createMap({

zoom: 15,
bearing: 64.8,
pitch: 60,
hash: true,
});
map.addControl(createAmplifyGeocoder());
},
}
}
</script>
<style scoped>
#map {
z-index: 0;
height: 800px;
}
</style>
Load MapLibre GL Geocoder wrapper.
import { createMap, createAmplifyGeocoder } from 'maplibre-gl-js-amplify';
Load MapLibre GL Geocoder wrapper.
map.addControl(createAmplifyGeocoder());
Let's check with a simple local server.
npm run serve
Start up a local server and try logging in 💡
I was able to build an address search function using Amplify Geo and MapLibre GL Geocoder 👍
We have confirmed that the combination of Amplify Geo and MapLibre GL Geocoder makes it easier to build an address search function than using Amplify Geo as it is. I will continue to explore other features as well 👍
