graalvm 内置require 模块的开启

实际上graalvm 包含了体验特性的require 支持（commonjs）

配置说明

Map<String, String> options = new HashMap<>();

// Enable CommonJS experimental support.

options.put("js.commonjs-require", "true");

// (optional) folder where the NPM modules to be loaded are located.

options.put("js.commonjs-require-cwd", "/path/to/root/folder");

// (optional) initialization script to pre-define globals.

options.put("js.commonjs-global-properties", "./globals.js");

// (optional) Node.js built-in replacements as a comma separated list.

options.put("js.commonjs-core-modules-replacements",

            "buffer:buffer/," +

            "path:path-browserify");

// Create context with IO support and experimental options.

Context cx = Context.newBuilder("js")

                            .allowExperimentalOptions(true)

                            .allowIO(true)

                            .options(options)

                            .build();

// Require a module

Value module = cx.eval("js", "require('some-module');");
