I am using this bitcore npm package. https://bitcore.io/api/lib

And i want to monitor all the transactions over the blockchain, and read the input address, output address and amount associated with that transaction.

But i am unable to find the javascript method to invoke to accomplish this. Even i am not able to find a example for this.

I am looking for as short as something like

var someLib = require('some-bitcore-lib')

someLib.on('block-recieved', function(){
   // print everything
   console.log(arguments);
   // do something else;
})

Any help? Where can i find that some-bitcore-lib or how can i create that in nodejs?

Consider using bcoin.js which is in pure JS. It fires events when a transaction takes place. Quite simply you can do:

node.on("tx", (tx) => {
   console.log(tx.outputs, tx.inputs)
})

Note that, in bitcoin, each transaction can have multiple outputs and inputs, so these are arrays of inputs and outputs. You can obtain the total output amount by summing across all output amounts. Additionally, in this case you wouldn't concern yourself with blocks - just transactions.
