Hi, The ModuleNamespace <https://source.chromium.org/chromium/chromium/src/+/master:v8/include/v8.h;drc=5d658083d506ff1bf14abdd2221d94cbcf4fae96;bpv=1;bpt=1;l=1591?q=v8::Module> object is the proper choice, you can have a look at the existing tests <https://source.chromium.org/chromium/chromium/src/+/master:v8/test/cctest/test-api.cc;l=26235;drc=5d658083d506ff1bf14abdd2221d94cbcf4fae96;bpv=1;bpt=1?q=v8::Module> . For future reference, you will usually find (a bit hidden and obscure, I agree) existing tests in V8's test-api.cc <https://source.chromium.org/chromium/chromium/src/+/master:v8/test/cctest/test-api.cc> .
Could you provide some more example code for the error you get with persistent handles? cheers, Camillo On Tue, 17 Nov 2020 at 01:11, Ben Ernst <boi...@gmail.com> wrote: > I am migrating my V8 code from using "plain scripts" to using "ES6 > Modules".
