In this course we teach you how to create admin reports with React using a query builder. Admin reporting is a broad topic, and getting started can be overwhelming.

In five modules, we cover configuration of the query builder, setting up a server, displaying data in a grid, chart, and map, as well as some more advanced uses of the query builder. It's about three hours long and comes with code samples.

The course is taught by Jake Boone, who uses React Query Builder in real, mission-critical applications for a large engineering and construction firm.

In this course, we'll be using React Query Builder to create admin reports with complex filtering, bulk editing, data grids, charts, and maps.

Building Advanced Admin Reporting in React

Now we'll add a Google map to the page that will show the locations of our UN/LOCODE ports. Add the dependency for loading the Google Maps API with React.

# Displaying a map

## Setup

Now we'll add a Google map to the page that will show the locations of our UN/LOCODE ports. Add the dependency for loading the Google Maps API with React.

```shell
npm i @react-google-maps/api
```

Create a new file called `.env` in the `client` folder and add [your Google Maps API key](https://developers.google.com/maps/documentation/javascript/get-api-key) as the variable `REACT_APP_GOOGLE_MAPS_API_KEY`. Make sure this file is listed in your `.gitignore` file.

```typescript { actualFilename=./protected/src/.env endChar=47 endLine=1 startChar=0 startLine=1 statedFilename=client/.env url=https&#x3A;//gitlab.com/fullstackio/books/building-advanced-admin-reporting-in-react/module_04/lesson_04.04/protected/src/.env }
REACT_APP_GOOGLE_MAPS_API_KEY=your_api_key_here
```

Also, add the API key as an environment variable to your Heroku app setup using the [online dashboard](https://dashboard.heroku.com/apps). Choose the **Settings** tab, then click **Reveal Config Vars** in the **Config Vars** section.
