maxSockets.js
// agent.maxSockets method Demo example // Importing the http & agentkeepalive module const http = require('http'); const agent = require('agentkeepalive'); const keepaliveAgent = new agent({ maxSockets: 100, maxFreeSockets: 10, timeout: 60000, // active socket keepalive for 60 seconds freeSocketTimeout: 30000, // free socket keepalive for 30 seconds }); const options = { host: 'tutorialspoint.com', port: 80, path: '/', method: 'GET', agent: keepaliveAgent, }; console.log("Max free sockets: ",keepaliveAgent.maxSockets); console.log('[%s] agent status changed: %j', Date(), keepaliveAgent.getCurrentStatus());
Output
