How to make Angular2 code written in typescript run in spring-tool-suite?
I can run the Angular 2 code written in javascript in spring-tool-suite, but in case of typescript, I am facing a lot of problems in the form of:
1. NOT FOUND errors
I am attaching a screen shot for the error
The errors you are getting (404 on javascript files) points that the backend (web server) is not configured correctly.
Potential Fix
Give webpack a go so that you only need to load a single bundle.js instead of having to over configure a web server backend.

I'm currently implementing the Monaco Editor from Microsoft (https://github.com/microsoft/monaco-editor), with a plugin for yaml validation, autocompletion, etc. . (https://github.com/remcohaszing/monaco-yaml) in our react js APP.
Maybe it is also important to tell you, that our authentication process gets managed via Keycloak.
When I'm running my code in development (React-scripts start) everything is working as expected.
I can create the editor, the schema gets implemented correctly and autocompletion is also working.
BUT as soon as I try to use the editor in PRODUCTION Build it seems that it cant load my workers correctly, following the editor is not working as it should.
I always get these errors in production:
I tried to use monaco-editor-webpack-plugin with React Rewired but it didnt have an positive effect either.
I also tried to use the worker loader to load the workers, but it also didnt help
Any more Ideas how I can fix this ? Has this to do something with CORS ? Because it tries to load files in a url? Or am I missing something ?
Thanks in advance
What I tried: Monaco Webpack Plugin, plain webpack, worker-loader
Expected Behaviour: Monaco Editor with Monaco Yaml working in production build.
Current behaviour: Working fine in development build, cannot load workers in production.
The problem was, that my keycloak (on a different port) rejected to load the working scripts. After handling this problems, the editor is working fine.
I am starting to help someone with a new project. This project is React (React Native as is a mobile app).
The project is working fine on her laptop (in her browser), and when I scan the Expo QR code, the app works fine on my Android device.
However, trying to run it in my browser is throwing all these errors:
The 'Can't resolve' error doesn't make sense, because the correct react native files are there. Is this a cache problem? I have tried deleting the .expo/web/cache folder and starting over.
Also, why are there multiple errors in my console, but only one being shown in the information on the actual web page? Does this mean that the single error being shown is causing all the other errors, or it is the only one which needs fixing, or will it show the next error when I fix the one that is being shown?
Thanks
Seems to have been a known problem re babel. See the links below:

Is there a way I can turn my existing angular-cli into an angular project(with no cli)?
I want to do try something in my app, I get cros problem when i try to use form authentication even my server allow cors. so I don't want to use localhost 4200.
If you are using
Angular 1 : you can convert by adding all dependencies file paths in the index.html
Angular 2 : You should use transpiler(like babel ..) to convert your typescript code to javascript code and give those java script file paths in the index.html to work.(recommended to use angular-cli)
If you are facing CORS issue, for development workaround you can add CORS plugin to the chrome
I get this error only, when I use bundled js.Before bundled app works properly ,used react native version is 0.19.How to remove this error while bundled please help me
The screen shot is attached below
Ensure that your AppDelegate.m file is not registering the React URL as pointing to disk. In 0.19, no on-disk bundle is created when deploying to the simulator. It must fetch the bundle over localhost or another IP.
Just started a demo Angular2 project (no previous experience with Angular1/AngularJS. Have followed and extended from the online quickstart and tutorials, and all was fine. However I'm at the point where I would like to use some components from a library which is designed for AngularJS, and having no end of problems!
Most of the information available about AngularJS/Angular2 compatibility assumes that you have an AngularJS project that you're adding Angular2 components to - not the other way around - so what I'm hoping to do may not even be possible. What I've tried so far involves a simple stripped-back project based on the Angular2 quickstart, with a single Angular2 component that loads into the index.html. I'd then like to integrate components from the existing library (AngularJS-based) into this.
I've tried using UpgradeAdapter.upgradeNg1Component to create components from the library and add them directly into my Angular2 component
I've tried installing angularjs through npm, importing it in a script tag into my index.html and then using a combination of UpgradeAdapter.downgradeNg2Component and UpgradeAdapter.bootstrap to load my Angular2 as a downgraded module
Neither of these seem to work - the component fails to show, and the browser console tells me I've got an Uncaught SyntaxError: Unexpected token <
Evaluating http://localhost:3000/angular2/upgrade
Error loading http://localhost:3000/app/main.js
My best guess at the moment is that this is actually an unsupported scenario, and I need to have a 'proper' AngularJS app in order to use the UpgradeAdapter functionality from Angular2. Can anyone confirm this? Or is there something stupid I'm missing here?
Here is a working plunkr describing how to mix Angular1 and Angular2 elements:
http://plnkr.co/edit/yMjghOFhFWuY8G1fVIEg?p=preview
An important point is to bootstrap your main component on the UpgradeAdapter. This way all elements are available in providers (services / factories) and in directives (components / directives):
upgrade.bootstrap(document.body, ['heroApp']);

How to inject upgraded Angular 1 service/factory to Angular 2 component in ES5?
So the major problem in this case turned out to be the fact that it appears that the upgrade components aren't included as part of the basic angular 2 bundle. After adding:
<script src="node_modules/angular2/bundles/upgrade.min.js"></script>
to my index.html file the error I was seeing disappeared.
Thanks to the answer here for pointing me in the right direction!
