Installation

V8 binaries shipped with JJBridge V8 Engine are platform dependent. To keep the packages small (and to avoid loading the wrong libraries), we distribute a jar with a different classifier for each platform. Here is how you add it based on your target platform:

• For Linux add this to your pom.xml:

  <dependency>
    <groupId>srl.forge</groupId>
    <artifactId>jjbridge-engine-v8</artifactId>
    <classifier>linux</classifier>
  </dependency>

• For macOS add this to your pom.xml:

  <dependency>
    <groupId>srl.forge</groupId>
    <artifactId>jjbridge-engine-v8</artifactId>
    <classifier>macos</classifier>
  </dependency>

• For Windows add this to your pom.xml:

  <dependency>
    <groupId>srl.forge</groupId>
    <artifactId>jjbridge-engine-v8</artifactId>
    <classifier>windows</classifier>
  </dependency>

• For Android add this to your pom.xml:

  <dependency>
    <groupId>srl.forge</groupId>
    <artifactId>jjbridge-engine-v8</artifactId>
    <classifier>android</classifier>
    <type>aar</type>
  </dependency>

Usage

The full javadoc is available at https://www.javadoc.io/doc/srl.forge/jjbridge-engine-v8/latest/index.html.

Initialization

To get a JSEngine just use:

JSEngine engine = new V8Engine();

You can also pass flags to V8 by calling V8Engine.setFlags() before instantiating V8Engine.

Then instantiate a JSRuntime and use JJBridge as usual:

try (JSRuntime runtime = engine.newRuntime()) {
    // Do JavaScript things here...
} catch (RuntimeException e) {
}
