J2V8 focuses on performance and tight integration with V8. It also takes a 'primitive first' approach, meaning that if a value can be accessed as a primitive, then it should be. This forces a more static type system between the JS and Java code, but it also improves the performance since intermediate Objects are not created.\n\nWe developed J2V8 as a high performance engine for our multi-platform mobile toolkit [tabris.js](https://tabrisjs.com) and it is a great choice for executing JavaScript on Android devices.\n\nBuilding J2V8\n=============\nBuilding J2V8 requires building both the native parts and the Java library (.jar/.aar file). To build the native parts we first build V8 as a monolithic library and then statically link J2V8 to that. The Java parts are built with maven/gradle.\n\nJ2V8 uses a cross-platform, cross-compiling build-system written in Python.\n\nFor any further build instructions \u0026 details please read [BUILDING.md](BUILDING.md)\n\nTutorials\n==========\n * [Getting Started With J2V8](https://eclipsesource.com/blogs/tutorials/getting-started-with-j2v8/)\n * [Registering Java Callbacks with J2V8](http://eclipsesource.com/blogs/2015/06/06/registering-java-callbacks-with-j2v8/)\n * [Implementing WebWorkers with J2V8](http://eclipsesource.com/blogs/2015/05/28/implementing-webworkers-with-j2v8/)\n * [Multithreaded JavaScript with J2V8](http://eclipsesource.com/blogs/2015/05/12/multithreaded-javascript-with-j2v8/)\n * [Using J2V8 with Heroku](http://eclipsesource.com/blogs/2015/06/04/using-j2v8-with-heroku/)\n\nArticles\n========\n * [Announcing J2V8 4](http://eclipsesource.com/blogs/2016/07/20/announcing-j2v8-4/)\n * [Running Node.js on the JVM](http://eclipsesource.com/blogs/2016/07/20/running-node-js-on-the-jvm/)\n * [Shipping J2V8 as an AAR](http://eclipsesource.com/blogs/2015/11/04/shipping-j2v8-as-an-aar/)\n * [Announcing J2V8 3.0](http://eclipsesource.com/blogs/2015/07/08/j2v8-3-0-released/)\n * [J2V8 2.2 New and Noteworthy](http://eclipsesource.com/blogs/2015/04/23/j2v8-2-2-new-and-noteworthy/)\n * [Announcing J2V8 2.0](http://eclipsesource.com/blogs/2015/02/25/announcing-j2v8-2-0/)\n * [Highly Efficient Java \u0026 JavaScript Integration](http://eclipsesource.com/blogs/2014/11/17/highly-efficient-java-javascript-integration/)\n * [React.js SSR with J2V8](https://ebaytech.berlin/react-js-server-side-rendering-with-j2v8-b9ced07888fb)\n\nPresentations\n=============\n * [J2V8 A Highly Efficient JS Runtime For Java](https://www.eclipsecon.org/na2015/session/j2v8-highly-efficient-js-runtime-java)\n * [Running JavaScript Efficiently in a Java World](http://www.slideshare.net/irbull/enter-js)\n\nOther Resources\n===============\nHere is a list of articles I've written on J2V8 [http://eclipsesource.com/blogs/tag/j2v8/](http://eclipsesource.com/blogs/tag/j2v8/).\n\nWho is using J2V8?\n========\n\nHere are some projects that use J2V8:\n* [tabris.js](https://tabrisjs.com)\n* [tern.java](https://github.com/angelozerr/tern.java)\n* [PlantUML](http://plantuml.com/)\n* [jooby](http://jooby.org/doc/assets)\n* [Alicorn](http://alicorn.io)\n\nLicense\n=====\nThe code is published under the terms of the [Eclipse Public License, version 1.0](http://www.eclipse.org/legal/epl-v10.html).\n","project_url":"https://awesome.ecosyste.ms/api/v1/projects/github.com%2Feclipsesource%2Fj2v8","html_url":"https://awesome.ecosyste.ms/projects/github.com%2Feclipsesource%2Fj2v8","lists_url":"https://awesome.ecosyste.ms/api/v1/projects/github.com%2Feclipsesource%2Fj2v8/lists"}
