I'm learning backend and API development and trying to understand how to implement some features from scratch without using any paid third party service.

I want to understand this concept from design as well as implementation pov. Please share if you have any resources where I can learn how to code the below service.
How to build in app notification service like one of these from scratch ?
These are different from push notifications like
Push notifications need not be stored permanently in any database but what happens with in app notifications? How to build such service which is scalable too.
One possible solution I could think of is this, for notification on post like
But I wonder how scalable is this approach.
I searched but couldn't find any good resources regarding this, so please if anyone could explain this or provide link to any blog or videos it will be helpful. (P.s. I'm an undergrad student and don't have experience in system design and architectures, just started learning about these so just curious)
Thanks.
User notifications significantly increase engagement in social apps and productivity in business apps. Today, email notifications, web notifications, and cross-platform mobile push notifications have become the standard in user expectations. While some savvy customers want notifications sent to their Slack channels, others might want SMS notifications. Keeping customers in the loop through all the channels is a monumental task--and not one of your development team's core competency or interest.
Before Mailgun and Postmark were on the map, companies struggled with reliably delivering emails. Before Facebook Connect or Google Auth, everyone built their own authentication systems.
All products know the benefits of having a notification service of sorts, but few truly spend the time and money needed to implement their own in the right way. It is usually not fully thought out and far exceeds initial expectations. Despite the time and effort invested, it will often not deliver all the anticipated features. Additionally, as the notification system grows in complexity, more maintenance and upgrade expenses will arise.
Not anymore. With MagicBell, nobody has to worry about building a notification system, bespoke or otherwise, ever again.
Let's consider the most basic, cross-platform notification setup. A system event requires a user notification (for example, if they were tagged in a comment). If you provide a web app, you'll need to verify the user is online before sending them a notification in-app. If they are offline, you'll need to push the notification via email. (You can push the notification through both channels, but we believe this practice to be less effective).
If you also offer a mobile app, you may send them a push notification, but then you should remember to remove it if your user sees it on another notification channel. To get an idea of just how complex the notification system can get, look at this flow chart that Slack, which offers a visual of their notifications logic:

And that's just the basic notification. What if you would like your users to act on notifications, send them a digest version, or offer other channels like Slack or SMS? Then things get even more complex. What if you want to split-test your notification? Or access analytics on the effectiveness of your notifications on user engagement? It is guaranteed you will have to build out even more pathways.
Many companies build a notification system but barely have time to maintain or improve it. Notifications are not just fired and forgotten. You need to worry about deliverability, giving your users subscription options and troubleshooting help. You also need to be aware that many users will unsubscribe without robust notification delivery preferences at the first sign of a notification they consider irrelevant. So, engagement in these messages is something to keep in mind for your product's general success or return usage.
An additional concern is the management of notification preferences; you'll need to build a screen where they can select how and when they want to be notified and about what. Finally, there's security. Most don't have any debugging or customer support infrastructure around notifications and just hope for the best. This approach can also lead to unsubscribes or unengaged users.
There's a silver lining. These implementation patterns are highly similar across products and companies and render themselves well to a SaaS service.
We have been thinking about the problem of building a notification system for many years in SupportBee and finally decided we were the ones to solve it.
We introduce our solution: MagicBell.
One more thing.
Apps and services almost always offer email notifications. In the early days of MagicBell, we allowed users to turn their email inboxes into a notification centre, automagically. All you had to do was to BCC: your email notifications to a project-specific magic email address, and we did the rest! MagicBell sorted emails and understood who the notification was for, what the notification's title was, and where it should direct the user.
We now offer far more than just supercharged email notifications. Using a customisable notification API endpoint, you can send up to 1000 notifications in a single request across multiple channels, depending on your preference. All in real-time. These channels include email, web push, mobile push, Slack and SMS. How you send the notification and how it is received depends on how you identify users in your app.
Despite the power of our notification inbox, you can still launch within an hour. For more details on how and what we do you can also refer to our Docs page sending notifications.
We are already powering the notifications for companies like Pitch and GitBook. We invite you to give us a try and test MagicBell in your product.
