JHipster is a great tool to quickly build your application or just the prototype. And when you’re building your MVP you most of the time need to move fast.

If you’re here, you’re probably looking for a way to disable it temporarily or once for good.
In this text, I’m going to show you how you can achieve it.

Geocoding is the term used to describe the process of exchanging address into corresponding geographical data (coordinates).
If you’re looking for out-of-the-box geocoding services there are plenty of them. For example, you can consider the most popular one – Google Maps Geocoding API which is pretty good but it’s not really free to use.
There’s a different solution, especially if you’re using OpenStreetMaps-related maps engine. It’s called Nominatim and basically it’s the OSM searching engine with open web API.

As you probably noticed, I familiarize myself with the subject of Firebase Cloud Messaging push notifications recently.
This time I would like to share with you my push notifications server-side application. The app is made with the Spring Boot framework.
The provided example covers most common notifications sending use cases such as: sending push notification to a topic, directly to the users’ device, or sending messages with additional data payload.
This post is not a step-by-step tutorial. I’ll focus on the most important parts. A fully working example is available on GitHub.
If you don’t have a client-side application to receive push notifications yet, you should consider the use of the Ionic app I described earlier. Have fun!
