Use case
A method likenet_listening
can be used to monitor the network status of the Polygon node a developer is connecting to. Imagine a blockchain explorer where users can search for transactions, addresses, and other information on the Polygon blockchain. In order to provide accurate information to its users, the website needs to be able to monitor the current status of its connection.
Here is an example of this implementation using the web3.js library:
index.js
monitorNetworkStatus
function defined in this code uses the net_listening
method to check whether the Polygon client is currently listening for network connections, and the net_peerCount method to get the number of peers currently connected to the client.
The function logs this information to the console, which could be displayed to the user in a user-friendly format on the blockchain explorer website. By calling this function at regular intervals using the setInterval
function, the website can continuously monitor the node’s status and provide users with up-to-date information about the overall health of the node.
