I am trying to connect to an endpoint that does http streaming of json data. I was wondering how to perform a basic request using Go's net/http package and read the response as it comes in. Currently, I am only able to read the response when the connection closes. 

resp, err := http.Get("localhost:8080/stream")
if err != nil {
    ...
}
...
// perform work while connected and getting data

Any insight would be greatly appreciated!

Thanks!

The answer provided by Eve Freeman is the correct way to read json data. For reading any type of data, you can use the method below:

resp, err := http.Get("http://localhost:3000/stream")
...

reader := bufio.NewReader(resp.Body)
for {
    line, err := reader.ReadBytes('\n')
    ...

    log.Println(string(line))
}
