Node.js agent.maxFreeSockets Method
The Node.js HTTP API is low-level so that it could support the HTTP applications. In order to access and use the HTTP server and client, we need to call them (by ‘require(‘http’)‘). HTTP message headers are represented as JSON Format.
The agent.maxFreeSockets (Added in v0.11.7) method is an inbuilt application programming interface of the ‘Http‘ module which sets the maximum number of sockets that will be left open in the free state.
In order to get a response and a proper result, we need to import ‘http’ module.
const http = require('http');
Parameters: This function does not accept any parameters as mentioned above.
Return Value <number>: By default, it is set to 256. For agents with keepAlive enabled, this sets the maximum number of sockets that will be left open in the free state.
The below examples illustrate the use of agent.maxFreeSockets method in Node.js.
