It’s important to realize that there are several ways that you can use when implementing push notifications; a service that will enable you to be in constant touch with your customers. To point out, there are multiple operating systems that come with this feature and you’ll only be expected to enable them. It’s a common practice when you’re using Android, Windows, macOS together with iOS apps where users are normally notified about the new apps using the available apps. For example, FCM is a renowned messaging platform that allows subscribers to send messages at absolutely zero costs. With this tool, your customer can get notified if there’s a new data arrival that needs synchronizing.
If you’ve both macOS and iOS devices, there’s APNS which is considered as a basic feature for remote notifications. The tool that’s majorly used by app developers has gained popularity because it’s seen as being secure and more reliable when sending information. When you’ve access to a personal computer, there’s a WNS that works just like APNS and can also allow developers to send push notifications to users. The only factor standing in between the two is the respective devices that they support. It must be remembered that using third-party tools to create push notifications is recommended because it’s time cautious. Equally, they come with several graphic interfaces that are easy to use more so when you’re a starter.
However, if you want your push notification services to have extra features, you’re advised to create your push notifications service from your device’s server. Here, there are three methods that you shouls apply, including HTTP Long Polling, HTTP Streaming and not to mention WebSocket. In HTTP Long polling, it’s the customer that initiates push notifications request and it’s within the server’s power to check whether if new notifications have come. Although it might be true that it’s easy to implement HTTP Long Polling, this tool does not provide real-time notifications. Things will be worse in situations where there are no clients to initiate the process, and this can make the service to become ineffective.
The second method that you can use in creating your push notifications is the HTTP Streaming. Apart from the closure of the connections, everything in HTTP Streaming is similar to HTTP Long Polling. When you’ve access to this service, expect a chunked response from the server. Whenever a server gets new notifications, it simply writes to its socket. HTTP Streaming has some advantages over HTTP Long polling, including providing real-time notifications. On the negative side, memory usage is reduced since notifications from customers tend to pile up.
A point often overlooked is that this server can be accessed by unauthorized people through hacking. In the same way, you can Web Socket when you need a two-way communication network. Web Socket seems to have more advantages over the first two methods. When using Web Socket, you need to be sure that your notifications will be pushed to the customers at any time. But the only challenge when using Web Socket is the fact that it’s not compatible with older browsers,
