EventLogger

An HTTP server that accepts POST requests (JSON) from multiple clients' websites. Each request forms part of a struct (for that particular visitor) and each stage of construction(representing an event) is logged to the terminal up until the struct is fully constructed. Below is the Event struct constructed.

Event Struct

type Event struct {
	WebsiteUrl         string
	SessionId          string
	ResizeFrom         Dimension
	ResizeTo           Dimension
	CopyAndPaste       map[string]bool // map[fieldId]true
	FormCompletionTime int // Seconds
}

type Dimension struct {
	Width  string
	Height string
}

Event options

The following are the possible events a frontend client can capture and post.

• if the screen resizes, the before and after dimensions
• copy & paste for each field in a form
• time taken, in seconds, from the first character being typed to submitting the form

Example JSON Requests

{
  "eventType": "copyAndPaste",
  "websiteUrl": "https://stripe.com",
  "sessionId": "123123-123123-123123123",
  "pasted": true,
  "formId": "inputCardNumber"
}

{
  "eventType": "screenResize",
  "websiteUrl": "https://stripe.com",
  "sessionId": "123123-123123-123123123",
  "resizeFrom": {
    "width": "1920",
    "height": "1080"
  },
  "resizeTo": {
    "width": "1280",
    "height": "720"
  }
}

{
  "eventType": "timeTaken",
  "websiteUrl": "https://stripe.com",
  "sessionId": "123123-123123-123123123",
  "timeTaken": 72,
}

Getting set up

Setting this up is pretty straightforward and easy. You could compile and run in a single step by running the following from the base directory of this repo:

go run main.go

This is my personal first choice especially if this is being run in development and not deployed anywhere

But if you'd rather build first then run the executable a simple :

go build main.go

will build and save the excutable in the same directory which would be main file on Linux OR MacOS and a main.exe file on Windows. which you can then run by typing ./main on Linux and MacOS or by running thing main.exe file on windows.

After successfully started, the server runs on http://localhost:8080/ and the struct construction is logged to console whenever there's a POST request matching an event.
