react-native-db-models Uncaught error - javascript

I am wanting to use the react-native-db-models for local-db on my React Native iOS app.
I've npm installed react-native-db-models from here and have followed the instructions on the page of creating a db.js file that contains the example given on both Github page and NPM page. Then in the file that needs access to the DB, I've created vars for both DB and DBEvents, following the docs accordingly.
When running the project in Xcode it results in a Build Fail.
uncaught error Error: UnableToResolveError: Unable to resolve module
util from /Users/tmhn/Project/DoppioHealth/node_modules/react-native-db-models/node_modules/promise-es6/lib/utils.js:
Invalid directory /Users/node_modules/util
I have also npm installed the two dependencies listed on the npm page: es6-promises and eventemitter3, to no avail.
Note: DoppioHealth is the project name

Investigated the Github Issues and found this solved the issue

Facing an error when deploying React app to github pages

I'm trying to deploy my react app to github pages but facing some errors.
At first, when I tried to run npm run deploy in the terminal, it showed me this error:
new MiniCssExtractPlugin({
^
And MiniCssExtractPlugin is not a constructor
After that, I tried: npm i -D --save-exact mini-css-extract-plugin#2.4.5
This solved the problem but when I ran it again (npm run deploy), I get this error:
Creating an optimized production build...
Failed to compile.
The target environment doesn't support dynamic import() syntax so it's not possible to use
external type 'module' within a script
I don't know why it doesn't work, and also didn't find anything on the internet.
Thanks!

uncaught DOMException after installing and using polymer element

I am following this tutorial which teaches the installation of polymer elements:
https://www.polymer-project.org/3.0/start/toolbox/add-elements
After running the npm install command and importing it using:
import '#polymer/paper-checkbox/paper-checkbox.js';
I am starting to get this error when the page loads:
Uncaught (in promise) DOMException: Failed to execute 'define' on 'CustomElementRegistry': this name has already been used with this registry
I had a look around and some say delete node models folder and others say to reinstall web components because there are conflicts between versions but none go into great detail on how this is done.
For me, deleting node_modules and package-lock.json, then running npm install fixed this. It appears to be due to duplicate dependencies within paper elements.

How to use npm country codes

Hin I am new in node.js. I already created my project in cordova cross platform Mobile Application. Now I want to install npm country-codes package "https://www.npmjs.com/package/country-codes". I already install this from command line But I can't get country codes. It's display error
"Uncaught Error: Module name "countryCodes" has not been loaded yet for context: _. Use require([])
I don't konw how to solve it please help me.
I simple use this from npm doc. In my Project I used backbone.js and require.js
var countryCodes = require('countryCodes')
console.log(countryCodes)
Pay notice that this page module in NPM says the following:
This module is deprecated.
Please use the country-data package instead of this country-codes module. It is more well-maintained and the original author of this repository/package has decided to focus on that module instead. Here is a link to it: https://github.com/OpenBookPrices/country-data/. If you need help with a migration, please file an issue on that repository and tag #niftylettuce.
The second thing you need to do is to install it with npm command and it should appear under your node_modules folder
npm install country-codes
The error that you are experiencing is created by the common.js library which is the Node.js loader library.
This occurs when there is a require('name') call, but the 'name' module has not been loaded yet.

Meteor: "ReferenceError: module is not defined" after installing package

I created meteor package which contains ZiggeoSDK api to integrate ziggeo into my meteor app. After installing this package it is giving error:
ReferenceError: module is not defined
Ziggeo is Node Server SDK repository. And package contains ziggeo-sdk.min.js file.
Does anyone know how to resolve this issue.
Your problem is located at the line #11 in https://github.com/Ziggeo/ZiggeoNodeSdk/blob/master/ziggeo-sdk.js
This project uses Node.js modules. Check the require() functions too, they load other npm dependencies such as crypto or http.
You need to ask the owner for the npm package or create one yourself https://docs.npmjs.com/getting-started/creating-node-modules. Once the packages is ready, load it in Meteor using meteorhacks:npm.

Installed module not found in Titanium

I am having troubles using a module I have added to Titanium. I followed the official directions to install a module (more specifically this module: https://github.com/appcelerator/titanium_modules/tree/master/udp/mobile/android):
I have installed the ti.udp-android-2.1.2.zip file via help>Install Mobile Module
Then I added the ti.udp module to the tiapp.xml (since it was directly found and could be selected from the list, I assume the install of the module was successful).
I load the module with
var UDP = require('ti.udp');
Every time I start the application, I get the error:
Uncaught Error: Requested module not found: ti.udp
update
Image of the tiapp.xml:
Please go to tiapp.xml and see whether the module is being shown there.I don't think that your module added in tiapp.xml
Thanks
Your modules should be installed under %User%/AppData/Roaming/Titanium/modules
You can also verify what is your titanium sdk path in TitaniumStudio Window->Preference->Platform
I suspect that the tiapp.xml gets the modules from the Titanium Path, but the build will look for it in the User's path. That's why you do see it in the editor, but can't build
