How to export to CSV directly from a query using golang
I have a java script that exports website html table contents to CSV from a Web Application.
I would like to bypass that and when a button is pressed it runs a query and downloads it to CSV without first loading it to the html table.
Does anyone have anything like that?
This is useful for printing out reports. Some big reports that i have since they have to load in the website first cause too much lag.

You would just do something like:
func(w http.ResponseWriter, r *http.Request)
var data = string{{"Line1", "Hello"}, {"Line2", "World"}}
buffer := &bytes.Buffer{} // creates IO Writer
writer := csv.NewWriter(buffer)
for _, value := range data {
err := writer.Write(value)
checkError("Cannot write to buffer", err)
}
writer.Flush()
w.Header().Set("Content-Type", "text/csv") // setting the content type header to text/csv
w.Header().Set("Content-Disposition", "attachment;filename=TheCSVFileName.csv")
w.Write(buffer.Bytes())
}
