I start learning recently polymer.
I want to hear yours opinion if its make sense to use both frameworks polymer and angular together or not and if polymer is really ready for production and what is your choice?
Polymer and Angular Together
Yes, of-course they both can be used independently as well as together. Actually they both are two different things and to serve two different purposes, Though they have some common features to offer.
Please refer to this answer for a detailed explanation. It covers more things and tells about how Polymer & Angular both can be used as part of the same project.
Polymer for Production
With the release of Polymer 1.0, they claim it to be the production ready and as per them they have focussed more on the speed and efficiency this time. As a major change of this release they have replaced the shadow dom with shady dom.
Finger Crossed, I am also intending to use it in my project. Though I have heard very little of it being used in Production by others.
I think Yes, is not a bad choice ! For example i try to use Angular for the little bit complex Service like the Auth Token Authentication, and Polymer for the others ! I want to use Material Design and the right choice is Polymer throught the Paper Element, i tried ngMaterial but is not so good like the Material in Polymer .... so my Answer for the Moment is Yes !

I know that polymer is primarily used to create reusable elements, and angular is supposed to be used to create web apps (at least from a "high level" perspective), but I wonder, since you can wrap your own "Screens" as polymer elements, which actually could serve as controllers too, and switch the active page with the iron-pages element (see SPA demo), and you can also use more-routing well... instead of "routing by code", it supports one/two way binding and events, I've actually done some small SPA app like that myself, and so far so good actually! moving on-
Assuming I don't care about having some built-in REST wrapper such as the one provided by Angular (Easy to roll up my own if I use Dart), then in Dart's case:
Could polymer actually be used to create full apps?
Would it have any implications in performance if my whole app is in polymer? by that I mean, every screen is really an element, and so on.
Development speed, maintainability, and experience? (considering the fact that I use Dart which helps a lot in these areas)
Overall, is it a good idea? I'd like to know your opinions.
Any companies/indie devs have done this before? not necessarily with Dart, but with TypeScript/JS as well, although I'm 100% set on Dart.
I think Polymer is quite a good fit for that. I wouldn't necessarily go for "a Polymer element per page" but that might depend on the kind of application you are going to build. Especially in Dart Polymer it's a good start to make the root Element a Polymer element. You can for example keep the navigation and switch only a part of the view instead of the entire page (but that might be what you had in mind anyway)
You can also use dependency injection, which is a strong point of Angular.
The dirty checking might be better in Angular 2 but Angular isn't released yet and Polymer also has plans to improve here.
I'm working on a project which has the luxury of using ECMA 6 on the latest browsers for a product that will be shipped in 1.5 years. So we thought why not use Web Components now that Angular 2 isn't available (which is going to be ECMA 6). And while we are at it, can we replace Angular altogether without having to go back to stone age?
How to replace Angular?
There's this site called youmightnotneedjquery.com which is basically about how modern browsers actually have most of the stuff that jQuery was traditionally used for. I'm interested to see something like that for Angular.
We mainly use four Angular features. What are my options for replacing them?
Angular Directives --> Web Components
Angular Modules --> ECMA 6 Modules (not exactly the same thing)
Angular Routes --> ???
Angular 2-way databinding --> ???
PS. We don't want to replace Angular with something similar like Backbone or Ember. We want to replace it with standard web technologies but if we have to use small tools to fill the gap, we'll consider it.
I've been researching in the past 3 weeks and turns out many people are thinking about an alternative after Angular took a drastic change path. Fortunately the upcomming W3C Web Components standard actually has all we need and it works right now with polyfills from the Polymer project. So to answer the question:
Angular Directives --> Web Components use the polyfill until all browsers support it.
Angular Modules --> ECMA 6 Modules part of the problem is solved with HTML imports. But you can also use Traceur until the browsers support it.
Angular Routes --> There's a component for that™ use <app-router>.
Angular 2-way databinding --> Polymer adds a "magic" layer on top of the plain standard web components. This includes many features including data-binding.

If you're wondering about the build process for concatenating files in order to reduce the number of HTTP requests, take a look at Addy Osmani's post about Vulcanize. Spoiler: you may not need it with the upcoming HTTP 2 optimizations.
Many Angular projects use Twitter Bootstrap for the layout. Polymer can do that plus it plays nicely with Google's Paper elements (totally optional but superbly awesome).
If you want to make yourself familiar with web components in general, here is a bunch of nice articles: http://webcomponents.org/articles/
And here is a wealth of web components: http://customelements.io/ I don't know if it's going to be a new NPM, but the list components is pretty impressive and growing.
It's relatively complicated to expose an API for an Angular component. People have come up with all sorts of methods from link function to emitting events. In Web Components, however, it's really easy to make your component interact with the world outside and indeed the API and events you expose aren't much different from standard HTML tags like <audio>.
Just like Angular, you can use Polymer with Dart as well.
Conclusion
Overall, I don't see any reason to use Angular except if:
You have a huge source code investment in angular and don't want to port everything to standard web. (Angular 2.0 will deprecate your code anyway, so you're stuck with Angular 1.*)
Your team is too lazy to learn a new technology (in that case web might not be the right platform for this attitude anyway).
Angular was good for what it was doing and had its own Hype cycle. Web components solve many of the issues Angular was trying to address. Probably Angular had a role as a proof of concept for the Web components. But now it's time to move on. Web is reinventing itself everyday and it's inevitable to moves someone's cheese.
I'm not saying that Polymer is the ultimate answer to everything. At best it's another Angular which will render useless in a couple of years, but now it's a good time to learn and use it. The W3C standards don't die easily though, and Polymer tends to be much closer to them.
There's an element for that™ is the new There's an app for that™
TLDR: seriously consider writing an almost Angular 2.0-compatable Angular 1.3 app before rolling your own framework
It seems as if you've identified that Angular does a lot of things the right way and that's why you're attempting to replicate it, so basically you're going to roll your own by combining a hodgepodge of libraries. Unless you have an enormous investment of Engineering hours, the framework you build will likely be:
Lightly documented
A cross-browser maintenance nightmare and (worst of all)
Difficult for new hires to learn
If there wasn't a framework out there that did what you want to do already, I think rolling your own makes sense, but by trying to recreate Angular you're:
Taking on a lot of Engineering work that has already been done by a dedicated team, that could have been spent on building product
Made it MUCH more difficult to onboard new employees because you have to:
Find candidates that are willing to use a home-grown framework instead of growing their skills at an open source framework they could use elsewhere
Train these employees to use your framework (and good luck unless your documentation is mature)
I know your question asks how to replace Angular, but I've seen too many companies go the route of rolling their own and paying for it down the road. Again, if your budget includes a ton of core resources to build out (and document, and maintain) the framework and you don't think there is any chance corners will get cut when push comes to shove later if timelines get tight, then rolling your own might make sense. However, I think you should seriously consider reading up on how to write Angular 1.3 apps so that they're easy to port to Angular 2.0 and go the Angular route. Just look at the size of the community you're missing out on:

The owner of the DurandalJS project is now working at Google on AngularJS Next (v2?) in addition to keeping the current version of DurandalJS maintained. The two frameworks are converging.
http://blog.angularjs.org/2014/04/angular-and-durandal-converge.html
For a new mini-SPA project, which framework would be the best choice specifically with regard to the upgrade path?
I note that Rob Eisenberg has listed a number of tips to help existing DurandalJS users get ready for the next version, so it appears there will be an upgrade path available, but I'm wondering if the upgrade from AngularJS to the next generation framework would be simpler.
http://eisenbergeffect.bluespire.com/preparing-for-durandal-nextgen/
To be clear - I'm more concerned in making the right choice for the future (large SPA, split into multiple mini-SPAs) than for my current needs.
I'm not sure which one would be the best choice for now ... actually I'd say none of them is future save enough. Angular 2.0 is going to be definitely different from 1.0 and of course also from Durandal.
Nevertheless the framework itself maybe not that important. I think you should focus on separating code in reusable components. Whether it is a Angular Service/Factory/Provider or a clean Require Module in Durandal it actually doesn't matter. Getting it into the "NEW" Framework should be just a matter of adding the proper wrappers. As for 2-way-binding use the oberserver plugin to maintain clean POJOs.
The most important change from my perspective in NG2 will be the support of Lifecycle events, so even using those in Durandal now will be somehow supported in NG2. As for composition there for sure will be a way to simulate that easily in NG2 as well.
For current work the only two things important for the decision of the currently used Framework in my opinion are the use of RequireJS and Framework simplicity. Sure you can add it to Angular as well, there are several guides on that, but Durandal was built from ground up with RequireJS in mind. Especially in bigger projects this can save you a lot of headache from missing or wrong dependencies. As of the second argument -> porting Durandal to Angular is not that of a big deal because it's written in an easy and understandable way. Vice-versa may be a totally different story. Getting your custom Directives implemented as a combination of templating and ko-bindings can get pretty hard :)
So as a closing statement, if it's going to be a small project, but with the need for continuous support as well as update to NG2 in future, I'd go with Durandal. Besides RequireJS everything is exchangeable and adaptable. In the case of Angular I'm not sure how drastically the new DI system will change the way of development so that would be a show-stopper for me.
Btw. here is the design-document for NG2. So as you see there kinda everything that is important is gonna change:
Router
Persistance
Directives
Modularization (maybe we finally see RequireJS :) )
I m still new to client side MVC and at this point exploring my options.
Angular.js, Ember.js both are highly recommended frameworks, backbone.js is a library but most of the implementation user has to do.
Need a opinion from someone who has been working in client side MVC, as to how should one decide which one to go for?
Plus I need the UI to be media responsive, for which twitter Bootstrap looks ideal.
Is it possible to use one of these framework along with Twitter Bootstrap? In which framework is it easier to integrate Bootstrap?
Thanks.
AngularJs and Bootstrap are the two which I would start with.
AngularJS is opinionated, this means it will help you structure your code well. If you just want binding then don't forget knockoutjs. This is in the mvc package by default in VS.
Bootstrap is just html and css markup so should work with everything.
If you start a MVC5 project now in VS2013 you will by standard have bootstrap.
Many people will have different opinions on this so you could wait for an answer for a long time.
I understand your confusion when it comes to selecting the right JavaScript framework. There are many deciding factors that you must evaluate before dedicating your time and money. I noticed that you mentioned a MVC in your questions title. The first thing that you will want to understand is exactly which MV* architecture that you want to have for your app and why. Once you have that nailed down then selecting the framework will be much easier since you will have eliminated a few of the frameworks. The four architectures are MVC, MVVM, MVP and MV*. Another major factor that you will want to look at is the binding mechanism used for the framework. Some frameworks only allow one way bindings while others support 2-way bindings.
To answer your question, based on what you have explained, I would say that Ember is going to be your best bet. Ember will work with Bootstrap

I'm really enjoying learning to use AngularJS. Now I'm looking for components I can use with it. I've been looking at Angular-UI components but I'd like to know if it's possible to use the nice, supercharged components in ExtJS. Does anyone have experience with this? Any hints or tips or Angular directive libraries?
The company I work for is making a similar move. We currently rely heavily on an older version (3.x) of ExtJS, and the effort to upgrade to the current (5.0) version is at least equal to the effort required to move to angular.
To answer the question (to the best of my limited knowledge):
They can exist together in the same JS application.
Can you use UI elements of ExtJs with Angular?
You can put angular in control of markup via HTML templates in Ext.
Is this a wise idea?
Probably not.
Why would I consider doing this?
I need absolute control over the markup and don't care about possible page load issues
I need to serialize or de-serialize in some special way that Ext doesn't innately provide
I need to do something special like pub/sub (still totally possible with Ext)
In our case, it is a proof of concept for a few modals. If I am biased, I am biased in the direction of ExtJs (which is a huge statement given my background). The more exposure I have to ExtJS, the more I personally like it. I've used several frameworks in the past like Ember, Backbone, KnockoutJs and AngularJs and they are excellent tools that are reaching a level of maturity that makes them excellent choices. That said, they don't follow the same development model/pattern that ExtJs does, and I don't think a direct compare is fair to either side.
It would be almost like comparing Ext to Node (silly, I know).
If your project requires some special functionality that you don't believe is possible in Ext, you are probably like me and have limited experience with it. If you have a lot of experience with Ext, and want to try what we are trying, I say go for it. The single downfall of Ext is the size of the built package that is delivered. Another small framework isn't going to help that, but it also isn't going to cause more pain.
In the end, for me, I just love JS and expanding my knowledge of how things work now and in the future.
For the post above asking about the lack of traction for Ext: the answer is simple... it's not free, and thus not an option for many of us who aren't writing commercial software that fits well with the license.
In our AngularJS app at work, we have integrated a 3rd party ExtJS app with it, not for its UI components though. We open certain popups of that app based on user input and when the user commits data in the popup, we respond to ExtJs events to refresh our app. AngularJS is flexible enough to integrate with any other Javascript code/libraries as long as the library has public events to respond to. I would recommend going through the Directive and scope documentation on how to effectively create directives and respond to scope events.
Personally I do not feel ExtJS and AngularJS would be needed together, unless you are forced to use it like me. There is http://angular-ui.github.io/ that brings in a lot to the table. Again any given JQuery plugin can be integrated using directives, filters etc in AngularJS. So you may want to investigate into that before trying to bother with ExtJS.
Why do you need AngularJS anyway if you have ExtJS? I agree learning Ext can be somewhat difficult though once you've bitten through it there is nothing better at the moment. The only disadvantage is the heavier footprint but who cares? It's not like it's causing any problems... We use nothing but ExtJS at work and the progress in our apps is amazing. It integrates seamlessly with Spring MVC. We don't need to hack in HTML directly which I consider more of an advantage than a disadvantage: no more writing tags, no more open/close tag issues, you can still use css and Ext handles any browser incompatibilities so what else do you need more?? Angular is just the new kid on the block but in total it can not (yet) compete with ExtJS. It doesn't even com close. Just my 2$.
Sencha is planning to add support in the framework. Please find the link at the bottom for reference:
At SenchaCon in Las Vegas on November 7-9 2016, Sencha will be introducing the ability to use Ext JS components, layouts, and themes within an Angular 2 application, which we are currently calling the Ext JS Bridge to Angular 2 (also known as ‘The Bridge’).
