I use built-in JSON.stringify() like this
<https://github.com/pmed/v8pp/blob/master/v8pp/json.hpp#L19>:
/// Stringify V8 value to JSON
/// return empty string for empty value
std::string json_str(v8::Isolate* isolate, v8::Handle<v8::Value> value)
{
if (value.IsEmpty())
{
return std::string();
}
v8::HandleScope scope(isolate);
v8::Local<v8::Object> json = isolate->GetCurrentContext()->
Global()->Get(v8::String::NewFromUtf8(isolate, "JSON"))->ToObject();
v8::Local<v8::Function> stringify = json->Get(v8::String::NewFromUtf8(
isolate, "stringify")).As<v8::Function>();
v8::Local<v8::Value> result = stringify->Call(json, 1, &value);
v8::String::Utf8Value const str(result);
return std::string(*str, str.length());
}
By the way, there is v8::JSON::Parse() function in V8 API, and I'm wondered
why there is no v8::JSON::Stringify() counterpart.
