How can I debug J2V8/node.js when running within JVM?

阅读更多关于 How can I debug J2V8/node.js when running within JVM?

问题 Typically, I use node inspector (https://github.com/node-inspector/node-inspector) to debug node.js. Can this be used to attach to a remote node.js instance running in the JVM via J2V8? Also, it looks like the dev version of node.js supports native Chrome debugging: https://github.com/nodejs/node/pull/6792. If J2V8 adopts this version of node.js, will I be able to simply attach the Chrome debugger directly to the JVM? 回答1: If the question is still relevant - I have created j2v8-debugger

问题 I am using J2V8 for execute JavaScript code on Android. In my Java code, can I access and execute JavaScript functions of a separate .js file? If it is possible, how can I do that? Thank you: Bernat 回答1: Like with many JavaScript environments, you simply load the script that contains the other functions you wish to execute browser example. Any functions that are added to the global scope, are now available to you: V8 v8 = V8.createV8Runtime(); v8.executeScript(readFileAsString("script1")); //

问题 I have a gradle project that uses j2v8_android 2.2.1 library (which provides Java bindings for V8 JS engine - android port). Unfortunately, after executing the project (build succeeds without issues), I get an exception related to missing j2v8_android_x86 library file. The issues occurs when trying to create V8 runtime: V8 runtime = V8.createV8Runtime(); The exception itself is: Caused by: java.lang.IllegalStateException: J2V8 native library not loaded. at com.eclipsesource.v8.V8

本文首发于 vivo互联网技术微信公众号链接： https://mp.weixin.qq.com/s/ovOS0l9U5svlUMfZoYFU9Q vivo web service是开发团队围绕奇点内核打造出的基于vivo手机平台的web服务引擎，该服务引擎从浏览器产品线中经过多年迭代而出。除了提供可靠的基础Web服务，服务引擎还集成了非常强大的扩展功能。本文从架构方面对该服务引擎进行一次简单剖析，帮助读者对vivo web service有一个整体了解。 1. 奇点内核在多年的浏览器开发工作中，开发团队逐渐迭代出一款有竞争力的内核产品–奇点内核。从架构上讲奇点内核已经不是一款单纯的系统 WebView 替代产品，它集成了丰富的扩展功能，同时具备高性能、稳定性强的特点。奇点内核架构示意图这么丰富的功能如果仅提供给浏览器使用，无疑是大材小用了。我们举几个例子：深色模式。这是最近非常火热的功能。然而，从Android Q开始系统WebView才逐渐支持深色模式。这对于在无法升级到Q版本的Android平台的开发者来说，仅使用系统WebView来实现类似的效果，无疑是巨大的挑战。幸运的是，使用奇点内核可以轻松的获取比系统WebView更好的深色模式效果，同时支持按需调整样式，这应该是应用开发者的巨大福音了。稳定性。系统WebView的崩溃率数据约为0.4%左右
