Using modules with SES

[vamshich13]

Hello, I am trying to use modules in SES.
I was able to run the code below with mySESCompartment.import. How can I use mySESCompartment.importNow? I want to execute module code synchronously.

import "ses";
import { StaticModuleRecord } from "@endo/static-module-record";

const additionModuleSrc = `
    export function add(a, b) {
        return a + b;
    }
`;

const mainSrc = `
    import { add } from "additionModule"
    const res = add(100000, 2000000);
    console.log(res);
`;

const moduleMap = {
    "additionModule": additionModuleSrc,
    "main.js": mainSrc
}

const endowments = {
    console
}

const mySESCompartment = new Compartment( endowments, {}, {
    resolveHook: (moduleSpecifier, _moduleReferrer) => {
        console.log("resolveHook: ", moduleSpecifier, _moduleReferrer);
        return moduleSpecifier;
    },    
    importHook: (moduleSpecifier) => {
        console.log("importHook: ", moduleSpecifier);
        return new StaticModuleRecord(moduleMap[moduleSpecifier], moduleSpecifier);
    }
});

// This works but I want it to be synchronous
await mySESCompartment.import("main.js");

Please reply to my query, [ @naugtur @kriskowal @michaelfig ]

To get synchronous execution under importNow, the module and its transitive dependencies must first all be loaded, which is an asynchronous operation. So: ```js await c.load(s) c.importNow(s) ```
