Online resources are scarce on this topic, but I am facing a common issue in application development. My project involves multiple users accessing and editing a shared database simultaneously. The challenge is ensuring that all users have an accurate and up-to-date view of the database at all times. What is the most effective approach to subscribing to database changes and managing them in a MEAN stack environment?
In order to create a dynamic real-time system that updates instantly based on changes in the database, utilizing web sockets is essential. With Node.js as your backend, consider exploring Socket.io for this purpose.
A helpful guide for implementing this can be found here.
However, integrating web sockets will require significant modifications to both your Node.js and Angular code.
Alternatively, although not recommended, you could opt to make periodic API calls to update views in real time. This approach involves using setInterval.
