If you declare a JSONValue like this:
JSONValue json;

then:

assert(json.type() == JSON_TYPE.NULL);

Documentation at 
https://dlang.org/phobos/std_json.html#.JSONValue.type.2 
suggests not to change type but to assign a new value instead.

My problem is: how can I assign an empty object like {}?

The only way i found is using that deprecated method:
json.type = JSON_TYPE.OBJECT;

or

json = `{}`.parseJSON;

Please notice that to init as array this works:
json = JSONValue[].init;

read this:

https://issues.dlang.org/show_bug.cgi?id=15410

when you add the first key, the value will be set to 
JSON_TYPE.OBJECT

----
import std.json;

void main(string[] args)
{
    JSONValue json;
    json["first"] = 0;
    assert(json.type == JSON_TYPE.OBJECT);
}
