Getting multiple events when button pressed

[ScottChapman]

I am using a membrane button, one lead to ground, other to GPIO 12. Code below. Problem is that I occasionally get multiple events when I click the button...

var Gpio = require('pigpio').Gpio;
var button1 = new Gpio(12, {
    mode: Gpio.INPUT,
    pullUpDown: Gpio.PUD_UP,
    edge: Gpio.FALLING_EDGE
  });

button1.on('interrupt', function (level) {
        if (level === 0) {
                console.log("Button1 Pressed!");
        }
});

This is button bounce. There's an article describing the topic here. To resolve the issue with software consider using the lodash debounce function.
