Use Cases
Run JavaScript on GraalVM for optimal performance
JavaScript on GraalVM leverages the Graal compiler to provided unparalleled performance
Examples
Java <> JavaScript Interoperability
importorg.graalvm.polyglot.*;
public classExample1Context {
public staticvoid main(String[] args) {
System.out.println("[Java] Hello, Java!");
try (Context context = Context.newBuilder("js").option("js.ecmascript-version", "2020").build()) {
Value jsFunction = context.eval("js", "" +
"(function myJavaScriptFunction(parameter) { \n" +
" console.log('[JS] Hello, ' + parameter + '!'); \n" +
" return parameter.toUpperCase(); \n" +
"}) \n");
Value result = jsFunction.execute("JavaScript");
if (result.isString()) {
System.out.println("[Java] result: " + result.asString());
} else {
System.out.println("[Java] unexpected result type returned from JavaScript");
}
}
}
}Using Ruby in Node.js App on GraalVM
import// make sure to install the libraries first: `npm install http ansispan colors`
public classconst http = require("http");
public classconst span = require("ansispan");
require("colors");
http.createServer(function (request, response) {
response.writeHead(200, {"Content-Type": "text/html"});
response.write(span("Hello Graal.js!< br/>".green));
/start with `node --jvm --polyglot Example2Interop.js` to enable interop with Ruby:
try {
response.write("Ruby: " + Polyglot.eval("ruby", "[41,42,43]")[1] + "
");
} catch (ex) {
// Polyglot.eval("ruby", ...) failed
response.write("Ruby language not found
");
{
response.end("Request completed");
}).listen(8000, function() { console.log("Graal.js server at http://127.0.0.1:8000/".red); });
/*
to execute:
$ npm install http ansispan colors
$ node --jvm --polyglot Example2_Interop.js
*/
