If you're using a firestore database and have a collection called 'posts' to store individual posts, one approach is to include a 'views' counter for each post. This counter can be incremented every time a user clicks the button to view the post.
When the button is clicked, you can either increment the 'views' counter before or after retrieving the post data from firestore, depending on your preference.
This can be achieved using the firebase sdk or by utilizing a callable function for efficiency.
While this method allows you to track the exact number of post views, it's important to note that each view will incur a write operation cost beyond the free tier limit.
For scenarios where posts receive high traffic and precise view counts are not essential, you could consider incrementing the 'views' counter less frequently based on certain conditions. For example, incrementing by a set number every few views.
Alternatively, you could increment the counter based on specific criteria, such as a user viewing a significant portion of the post, to reduce write operations and potentially improve accuracy.
These suggestions are tailored to optimize performance and cost-efficiency based on individual requirements 👍🏼.
