Don’t render a template, but use a struct or map that you pass to c.JSON(), and create it in a way that it marshals into the required JSON.

Yeah I know it works with structs. I have to do it using templates but I’m not able escape the double quotes

Then you can’t use c.JSON() as I already said in another thread. You need to send a raw response and set the content type header on your own.

Yes! I followed what you said in the other thread, and it worked fmt.Fprintf(c.Writer, result). But is there any way I could do it with using c.JSON()

Because I’m building an api which users will consume and I’m thinking fmt should barely be used in the entire codebase

As soon as you pass a string to c.JSON it will be masrshaled into a JSON string. You say you do not want that, so you either can’t use a string or c.JSON.

Also there are other alternatives to fmt.F*. eg. io.WriteString(c.Writer, result).

I’m still the opinion, that handing a struct to c.JSON is the way to go though, as rendering a template might be more expensive than marshalling.

Okay yeah I understand, thanks for your help
