Hi all,
Calling IsFunction() on v8::Local is returning false, even though
v8::Local was pointing to a function in JavaScript. Is this
expected? Consider the following code -
#include

#include
#include
void Getter(v8::Local key,
const v8::PropertyCallbackInfo ) {

Hi all,
I'm trying to track when a variable becomes invalid.
Consider the following code where the variable goes out of scope -
function SomeFunction() {
for(let i = 0; i < 10; ++i) {
let instance = new MyClass(); // MyClass is implemented in C++
}
// instance goes out of scope and isn't
Checkout this project - https://github.com/hsharsha/v8inspector . It does
exactly what you're looking for. We're using the same at Couchbase and it's
working absolutely fine.

Hi all,
I have the following implementation -
class Evaluator {
public:
Evaluator();
void AddFunction();
private:
v8::Isolate *isolate_;
};
Evaluator::Evaluator() {
v8::V8::InitializeICUDefaultLocation("");
auto platform = v8::platform::CreateDefaultPlatform();
Thank you. I'm using v8 5.9.211. It doesn't have the
EscapableHandleScope::EscapeMaybe() function. Is there any other way to
achieve this?

Hi all,
I was wondering if it's alright to just return a *v8::MaybeLocal* from a
C++ function. We know that* v8::Local* objects must be escaped using a
*v8::EscapableHandleScope* if we are to return v8::Local from a
function. But I couldn't find the corresponding *Escape()* overload for

I'm trying to create a *CustomError* class by inheriting from the

Hi all,

Hello folks,
I was wondering if there's any v8 API that allows one to do base64
encoding/decoding. Browsers have window.btoa, but it's not part of the
global object in v8.
Thanks,

Hi all,
Please consider the following code -
void ParseJSON(v8::Isolate *isolate, const v8::Local _str) {
v8::HandleScope handle_scope(isolate);
auto v8val_json = v8::JSON::Parse(isolate, v8_str);
v8::Local v8obj_json;
if (!v8val_json.ToLocal(_json)) {
// Empty
return;
}

I'm trying to do the same with v8 5.9.211 on Windows and I have some
problems.
I created a new Visual Studio 2015 project and added hello-world.cc as its
source. I setup the include and lib directories in project configuration
and it builds without any warnings/errors.
As suggested in the
No, .ToLocalChecked() is called by my code, not from V8.
I would like to know if the APIs under v8::Private namespace has been
battle tested.

I've observed that the exception thrown is -
#
# Fatal error in v8::ToLocalChecked
# Empty MaybeLocal.

Is it possible to catch that exception to prevent v8 process from crashing?

Hi all,
I'm trying to use the private field of a v8::Object to store some data in
it as shown here - https://github.com/nodejs/nan/issues/587.
I was wondering if it's safe to use because when I try to read the private
field (Using FromJust() in the process), in the documentation

I'm observing a memory leak when the script crashes at runtime. Here the
