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:

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']);
These two answers could help you:
angular 1.x and angular2 together
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!

I am trying to render my REACT components via SSR with REACTJS.NET in ASP.NET project.
In the JS file for SSR, I'm importing SimpleBar component from simplebar-react package.
This is causing the error TypeError: Object doesn't support property or method 'forwardRef'.
I currently have 2 JS files, one for server and one for client. In the JS for server I am removing the adding of event listeners and similar. However, I can't get away from importing at least the npm package in both JS files.
Any idea on how I can avoid such error?
I am using Webpack + REACTJS.NET version 3.2.0.
So, after trying a lot of things, this is the best solution I came across.
Before I begin, I am aware that conditional imports is being introduced in ECMA but it isn't working for me, or at least, they way I have the project setup.
Basically, my solution is resolved by mixing ES6 with CommonJS and with help of Webpack and babel.
In Webpack I am creating a plugin:
And in code, when I want to import the Simplebar react component, I do the following in the constructor:
And then, whenever I want to use my imported component, I do the following:
This was the best way I found in order to render with SSR. I think it's okay since the content between server and client side are the same.
Does anyone know a better solution? Or do you have concerns?
I'm currently exploring an upgrade path for a pretty large AngularJS 1.6 app to Angular 6. I have my app bootstrapping as a hybrid app, and I've begun converting individual modules and components. I need to be able to do the migration in chunks, though. It would be nice if I could migrate a module at a time, but I'm running into some issues, to that end.
I have a NavBar directive which resides in my core AngularJS module. That component is being downgraded with downgradeComponent and registered on the AngularJS core module. The landing AngularJS module has a dependency on the core module so that it can use the NavBar. This works fine, because the LandingComponent has also been converted to Angular6 and is being downgraded and registered on the landing AngularJS module.
There is a problem with using the NavBar component inside of any other AngularJS component, though. I have a third AngularJS module called workflows with a ViewWorkflows component that has a NavBar inside its template. When I navigate to that component, I get the following error:
angular.js:14791 Error: No component factory found for NavBarDirective. Did you add it to #NgModule.entryComponents?
I can fix this by converting and then downgrading ViewWorkflows, but since NavBar is being registered as a downgraded AngularJS component, shouldn't any AngularJS module that declares a dependency on the core module have access to it?
Code (Not runnable)
Edit: I've updated the gist to be a little more simple. The landing module is Angular, with an Angular component, <landing> that is downgraded to run on the AngularJS landing module and has a <t-nav-bar> inside it. It has a dependency on the core module which provides the downgraded <t-nav-bar> directive. The <test> component is an AngularJS component registered on the AngularJS landing module that cannot use the <t-nav-bar>. Without even bringing the workflows module into the situation, it doesn't work. What am I doing wrong?
I have managed to sort this out. I was trying to declare the NavBar as an Angular #Directive. It actually needs to be a #Component. After making that switch, it works exactly as expected.
I spun up this repo to test with, and discovered the issue there. It's a new Angular 6 app that I "downgraded" for experimenting.
I've been wrestling with this for almost a day now, so I think it's time I give up and ask for help.
I started with a trivial AngularJS application (1.4.7) that should simply display "Greetings from Angular 1", and have been trying to bootstrap that application into a trivial Angular2 CLI generated app.
It doesn't seem to work. Instead of "Greetings from Angular 1", I see "{{angular1Msg}}". The following commit shows exactly what I did to include and bootstrap the app. I've spent quite a bit of time now with the documentation and am not sure what I'm missing.
Any help would be greatly appreciated!

The commit in which I attempted to integrate the AngularJS app:
https://github.com/scottschafer/ng2hybrid/commit/4b2c7c5339388ec2b3debeae0643dff89b75926f
(note that the source for the AngularJS app lives in src/ng1app, and is a working standalone AngularJS 1.4.7 application).
I finally got this working. A lot of trial and error. Not much fun at all.

just purchased Angle - Bootstrap Admin app from wrapbootstrap
Tried to run the angular-meteor version of the app
The first issue was that meteor did not like the contents of the default index.html, so I renamed the file to be index.ng.html
Now the error I'm getting in the browser console is:
TypeError: $browser.addPollFn is not a function angular-cookies.js:60
What can be done to fix this?
Not sure about wrapbootstrap, but generally this error means you are using incompatible versions of angular and angular-cookies.
The external angular modules you use (e.g. ngAnimate, ngCookies, ngResource, ngRoute etc), should always be the same version as angular.
This issue can be Resolved by using same Version of angular.min.js and angular-cookies.js.
It always good to use same version of files
I'm trying to put together an app, that uses both meteor and angular
I see, what appears to be two different base angular packages: one named angular:angular, and another named urigo:angular-meteor
The page for angular:angular says, that that is the actual angularJS repo, in which case, assuming that means that angular:angular is not an isopack) I'm not even sure on how to add that to a meteor app.
Which one of these should I be using to add angular functionality to a meteor app?
Urigo:angular-meteor is the package that you can use for development in meteor + angular. check out this video by uri himself explaining thoroughly about the package and development using it also.
