Set up Amplify Geo

Amplify Geo provides APIs and map UI components for maps and location search for JavaScript-based web apps. You can add maps and location search functionality to your app in just a few lines of code. Amplify Geo APIs are powered by Amazon Location Service and the map UI components from MapLibre are already integrated with the Geo APIs. You can quickly get started using Amplify CLI to provision your map and location search resources.

Follow this guide to get started with Amplify Geo through the Amplify CLI.

Notes:

• If you want to use existing Amazon Location Service resources follow this guide instead.
• If you want to use Amazon Location Service APIs not directly supported by Geo, use the escape hatch to access the Amazon Location Service SDK.

Provisioning resources through CLI

Prerequisite: Install and configure the Amplify CLI

The primary way to provision Geo resources is through the Amplify CLI. You can use the following command to install this globally.

npm i -g @aws-amplify/cli

Now, let's make sure that the right version was installed:

amplify --version

Note: Make sure that version 6.1.0 or above is installed.

Once that is complete, you can run the following command from your project's root folder to initialize Amplify in your repo:

amplify init

The above command will guide you through setting up your project name and preferred authentication profile.

Now you are able to add a geo resource, such as map resources or a search index:

amplify add geo

The CLI will let you configure the Geo category based on the capabilities you want to add (maps and/or search). You can either choose to stick with the defaults or configure advanced settings. Please refer to Amplify CLI Geo docs for more details on these configurations.

The add command automatically creates the backend configuration. Once all your configuration is complete, run the following (this might take a few minutes):

amplify push

A file called aws-exports.js that contains all geo-related configuration information is placed in your app's source directory.

For more information, you can visit the full Amplify CLI Geo Maps docs.

Configure your application

Install the necessary dependencies by running the following command:

npm install aws-amplify@^5

Note: Make sure that version 4.3.0 or above is installed.

Import and load the configuration file generated in previous step using Amplify CLI in your app. It’s recommended you add the Amplify configuration step to your app’s root entry point. For example src/index.js in a create-react-app generated React application or main.ts in Angular.

import { Amplify } from 'aws-amplify';
import awsconfig from './aws-exports';
Amplify.configure(awsconfig);
