memwatch

• 介绍
  • 监控内存leak, stats,leak在连续5次垃圾回收后内存没释放时触发, stats事件在垃圾回收时触发
• 堆内存比较

  • var memwatch = require('memwatch')
    var leakArray = []
    var leak = function () {
        leakArray.push('leak' + Math.random())
    }
    var hd = new memwatch.HeapDiff()
    for (var i = 0; i < 10000; i++) {
        leak()
    }
     
    var diff = hd.end()
    console.log(JSON.stringify(diff, null, 2))
