Getting the above error msg when installed the kochava latest version in next/react (web sdk). Need help to resolve this issue.
Getting the below error after adding "type":"module" in the package.json of kochava and running the app again:

Error: A dynamic link library (DLL) initialization routine failed on electron but it's fine on node js

I'm trying to load a custom module in electron written in D with node_dlang package, which is fine with node, but it fails within electron.
the test with node, that runs just fine, goes like this:
const nativeModule = require('./module.node');
const assert = require('assert');
assert(nativeModule != null);
assert(nativeModule.ultimate() == 42);
But when I went to use it within electron.js, through the preload script, it returns in an error.
the preload script goes like this:
const {
contextBridge,
ipcRenderer
} = require("electron");
const nativeModule = require('./module.node');
const assert = require('assert');
assert(nativeModule.ultimate() == 42);
function pageLoaded()
{
// ...
}
window.addEventListener('DOMContentLoaded', pageLoaded);
the error when I attempt to load the module within electron application is:
A JavaScript error occured in the browser process

What's causing this and how do I fix this?
version
node version is: v14.17.0
electron.js: v13.1.1
both are 64-bit.
the module source code goes like this:
import std.stdio : stderr;
import node_dlang;
extern(C):
void atStart(napi_env env)
{
import std.stdio;
writeln ("Hello from D!");
}
int ultimate()
{
return 42;
}
mixin exportToJs! (ultimate, MainFunction!atStart);
it's compiled with dub command line. No arguments.
UPDATE 1 Do I need to rebuild this module? I found this but it didn't work for me either. I installed the electron-rebuild package by npm install --save-dev electron-rebuild and rebuild with .\node_modules\.bin\electron-rebuild.cmd -v 13.1.1 the command ran fine but I still got same error.
UPDATE 2: inside the console, I clicked in the javascript source code file link in the error message (from the exception) it points to this line of code, where there's this comment saying that:
no static exports found
what does that mean? is this related to the methods in D class? they're marked as public... not sure if related

Electron is a Windows-Application and therefore you need to remove output to std. Try to remove
import std.stdio : stderr;
and
import std.stdio;
writeln ("Hello from D!");
and retry import to Electron.

Please refer this (https://stackoverflow.com/a/74280836/9558119) post from me regarding same. Since it is electron build might be missing Visual C++ Build Environment: Visual Studio Build Tools

Resolve "Cannot find package" error using Node.js

I'm trying to import a module using Node.js. When I specify the path I'm importing from, it works perfectly fine. Code below runs without returning any error
import myFunc from("./lib/myPkg.js");
import pkg from ("root/node_modules/date-names/index.js");
const {days, months} = pkg;
However, I get this error when I try to import an npm package by calling import ordinal from "ordinal"
root#username:/path/to/main.mjs# node main.mjs
internal/process/esm_loader.js:74
internalBinding('errors').triggerUncaughtException(

trying to run npm package (readability) from browser using Browserify with no success

so i'm trying to make readabilityJs available to me from the browser.
i want to use it later in my app, i'm using BrowserifyJS + beefyJS to make it work.
here i'm trying to expose the function i want to use:
var read = require("readability-js");
module.exports = (url) => read(url, (err, article, meta) => {
// Main Article
console.log(article.content.text());
//
// Title
console.log(article.title);
// Article HTML Source Code
console.log(article.content.html());
});
than i using the function in index.js
var readability = require("./Readability");
const url = "https://tim.blog/2019/10/31/edward-norton-motherless-brooklyn/";
readability(url);
after that i'm running browserify to make bundle.js and beefy to run it all
browserify index.js -o bundle.js
beefy index.js 8080
here is what i getting:
bundle.js:35798 Uncaught TypeError: Cannot read property 'content' of undefined

can you help me implement it right?

Typescript module, require external node_modules

I need to use a simple node_module inside a simple typescript file, but it seems that the compiler doesn't want to get it.
Here's my simple ts file :
import glob = require('glob');
console.log(glob);
And I've got this error :
[13:51:11] Compiling TypeScript files using tsc version 1.5.0
[13:51:12] [tsc] > F:/SkeletonProject/boot/ts/Boot.ts(4,23): error TS2307: Cannot find external module 'glob'.
[13:51:12] Failed to compile TypeScript: Error: tsc command has exited with code:2
events.js:72
throw er; // Unhandled 'error' event
^
Error: Failed to compile: tsc command has exited with code:2

npm ERR! Exit status 8
npm ERR!
npm ERR! Failed at the skeleton-typescript-name#0.0.1 start script.
However, when I use a simple declaration in this same script, it works :
var x = 0;
console.log(x); // prints 0 after typescript compilation
What am I doing wrong in this case ?
EDIT:
Here's my gulp file :
var gulp = require('gulp');
var typescript = require('gulp-tsc');
gulp.task('compileApp', ['compileBoot'], function () {
return gulp.src(['app/src/**/*.ts'])
.pipe(typescript())
.pipe(gulp.dest('app/dist/'))
});
gulp.task('compileBoot', function () {
return gulp.src(['boot/ts/*.ts'])
.pipe(typescript({
module:'commonjs'
}))
.pipe(gulp.dest('boot/js/'))
});
gulp.start('compileApp');
Thanks for advance

You are using the correct syntax:
import glob = require('glob');
But the error: Cannot find external module 'glob' is pointing out that you are using a special case.
By default, the compiler is looking for glob.ts, but in your case you are using a node module, not a module that you have written. For this reason, the glob module will need special treatment...
If glob is a plain JavaScript module, you can add a file named glob.d.ts with type information that described the module.
glob.d.ts
declare module "glob" {
export class Example {
doIt(): string;
}
}
app.ts
import glob = require('glob');
var x = new glob.Example();
Some Node modules already include the .d.ts in the package, in other cases you can grab it from Definitely Typed.

Here is the error with your code
import glob = require('glob');
Because in node.js import is not a reserved keyword. If you require any module in your application, you simply require it using the statement
var glob = require('glob');
Once done you can then use
console.log(glob);
To print the value of glob.Replacing import will hopefully do the job for you.
