Limitations

It is important to understand the JavaScript runtime for artemis is not like normal JavaScript runtimes like NodeJS, Deno, Bun, etc. These runtimes are primarily designed to create web apps.

Therefore tutorials or example scripts created for other runtimes may not work with artemis. For example, the JavaScript function console.table() does not exist in artemis. However, the functions console.log() and console.error() do exist in artemis.

The JavaScript runtime for artemis is designed specifically to assist with scripting for IR and forensic investigations.

There are currently some additional limitations to scripting:

1. All scripts executed through artemis must be in JavaScript. You cannot execute TypeScrpt scripts directly. You must compile and bundle them into one JavaScript file.
2. The JavaScript must be in common JS format (cjs). EMCAScript (ES) module scripts are not supported. The example code below uses esbuild to bundle the main.ts file to JavaScript using CJS format via deno run build.ts:

import * as esbuild from "https://deno.land/x/esbuild@v0.15.10/mod.js";
import { denoPlugin } from "https://deno.land/x/esbuild_deno_loader@0.6.0/mod.ts";

async function main() {
  const _result = await esbuild.build({
    plugins: [denoPlugin()],
    entryPoints: ["./main.ts"],
    outfile: "main.js",
    bundle: true,
    format: "cjs",
  });

  esbuild.stop();
}

main();
