What is the best way to monitor the status of the mongoose connection in Node

Is there a way to continuously monitor the status of the mongoose package connection string after starting an instance, similar to when running 'npm start'?

I attempted the following approach:

setInterval(function(){ 
  if(mongoose.connection.readyState == 1){
    mongoStatus = true;
  }else{
    mongoStatus = false;
  }
}, 2000);

However, I'm wondering if there are predefined events in mongoose that can be utilized for this purpose?

Just to clarify, my objective is to develop a custom circuit breaker for all services, hence the need for frequent status checks.

Answer №1

If you're looking to handle connection events in Mongoose, you can make use of the predefined Connection events.

mongoose.connection.on('error' | 'disconnecting' | 'disconnected' | 'close', event => {
  mongoStatus = false // You can customize this as needed
})
