Determining a device’s geographic location while it is online is known as geolocation. A user must typically consent before an app may access their location data.
Using a device’s IP address to establish its location by city, state, or postal code is one straightforward example of geolocation.
The geolocation API for React Native is @react-native-community/geolocation. Google does not advise utilising the React Native API for geolocation, though, as it is slower and less precise than the Google Location Services API, which is advised.
Thank goodness, the React Native community has produced two top-notch libraries for React Native’s implementation of geolocation:
The react-native-location library will be used in this React Native geolocation tutorial. It is accessible via npm because it is a Node package.
We’ll create an application that can:
- requests authorization to access location information on your iOS and Android smartphone.
- Select the coordinates of your location
- sends or saves the coordinates of your location
Use of Node versions 10 and up is advised. To determine the version of Node:
$ node -v // returns node version
Note that managing several node versions installed on your machine is possible with nvm.
You can create a new project with React Native by using the built-in command-line interface. Npx, a component of Node.js, lets you access it without installing anything on a global scale.
