Compiled code only working if bytenode.compileFile is executed using the dev console

I’m running into a very strange issue while using bytenode to compile the .js files of my Electron app. I have a compile.js file, which will compile all my code into bytecode. If i try to use it by running require(“./compile”) from any .js file within the render process the compiled code won’t work and gives me an error message. If I on the other hand run require("./compile") from the dev tools console the compiled code works just fine.

compile.js:

const bytenode = require("bytenode")
const fs = require('fs');
const v8 = require('v8');

v8.setFlagsFromString('--no-lazy');

bytenode.compileFile("./src/modules/file.js", "./src/modules/file.jsc");

I have made a new pull request (#49 ) which fixes the issue.

I looks like the issue isn’t related to setTimeout but to async arrow functions in general. This code works:

document.getElementById("testBtn").onclick = (ev) => {
    document.getElementById("testP").innerHTML = "Before delay"
    delay(1000).then(() => {
        document.getElementById("testP").innerHTML = "After delay"
    })
}

This code works aswell:

document.getElementById("testBtn").onclick = async function (ev) {
    document.getElementById("testP").innerHTML = "Before delay"
    await delay(1000);
    document.getElementById("testP").innerHTML = "After delay"
}

This code will result in a crash:

document.getElementById("testBtn").onclick = async (ev) => {
    document.getElementById("testP").innerHTML = "Before delay"
    await delay(1000);
    document.getElementById("testP").innerHTML = "After delay"
}

delay():

function delay(delay) {
    return new Promise((resolve, reject) => {
        setTimeout(() => {
            return resolve();
        }, delay)
    })
}
