This article is a brief introduction to some best practices about web notifications and some typical mistakes we should avoid.

We have several instruments to measure users engagement, such as downloads or clicks. Highly engaged users tend to be more profitable as typically they conclude purchases and share the website content within their network.

When we consider push notifications, engagement can be measured as the average number of sessions the recipients generated by receiving the message within a defined period of time.

Nowadays we are used to receive a tactile feedback when we receive a text message or when we play a game on our phone.

Until now, native apps had the advantage of providing a deep experience to the users, being able to tightly interact with the hosting hardware.

However, thanks to the Vibration API we can enrich our web apps with a new functionality and let a device vibrate through our browser!

How to decouple your client app from mocked network responses.

Learning to code by ourselves can be overwhelming, not only for the difficulty of the subject, but also trying not to get lost in the humongous amount of tutorials and documentation available online. Luckily, there are resources that make things easier and fun, offering educational contents with a gamification aspect.
