javenode's Issues

Can Javenode support Android? I am using it on Android and received an error message

build.gradle:
implementation 'com.caoccao.javet:javet-android:3.0.4'
implementation "com.caoccao.javet:javenode:0.4.0"

A failure occurred while executing com.android.build.gradle.internal.tasks.CheckDuplicatesRunnable

Duplicate class com.caoccao.javet.annotations.CheckReturnValue found in modules javet-3.0.3 (com.caoccao.javet:javet:3.0.3) and javet-android-3.0.4-runtime (com.caoccao.javet:javet-android:3.0.4)

node-fetch support

I've done various examples with lambda-style js in microservices contexts, bundled using for example esbuild. The blocker for real world applications in those cases has always been that there are legitimate needs for consuming HTTP resources or emitting HTTP side effects.

What's your take on this?

While the http and https Node APIs are quite big, an alternative would be to maintain compatibility with node-fetch instead. Bundles could embed the node-fetch lib (which at runtime depends on http, https, zlib, stream ... and more) or somehow allow it to be injected/required/imported.

警告: 6 V8 callback context object(s) not recycled.

实例代码好像有问题

@test
public void SetInterval() throws InterruptedException {
try {
V8Runtime v8Runtime = V8Host.getV8Instance().createV8Runtime();
JNEventLoop eventLoop = new JNEventLoop(v8Runtime);
eventLoop.loadStaticModules(JNModuleType.Console, JNModuleType.Timers);
v8Runtime.getExecutor("const a = [];\n" +
"setInterval(() => console.log(2342), 1000);").executeVoid();
eventLoop.await();
} catch (JavetException | InterruptedException e) {
throw new RuntimeException(e);
}
Thread.sleep(10000);
}
这样执行是正常的。

但是实例无法工作正常【如下：】

@test
public void SetInterval() throws InterruptedException {
try (V8Runtime v8Runtime = V8Host.getV8Instance().createV8Runtime();
JNEventLoop eventLoop = new JNEventLoop(v8Runtime)) {
eventLoop.loadStaticModules(JNModuleType.Console, JNModuleType.Timers);
v8Runtime.getExecutor("const a = [];\n" +
"setInterval(() => console.log(23423), 1000);").executeVoid();
eventLoop.await();
} catch (JavetException | InterruptedException e) {
throw new RuntimeException(e);
}
Thread.sleep(100000);
}
