I have to integrate an existing UI application to a REST based back end. The UI is a single html page that uses JQuery + CSS to create a sliding tab experience. Both the UI and REST application are Spring Boot apps.
I'm new to Javascript frameworks. AngularJS made a lot of sense to me for data binding and updating the DOM.
However, now that I am trying to do the integration, there is a .js include in the UI that contains a massive set of JQuery plugins (they are just pasted in one after another).
AngularJS functionality like 'ng-repeat' does not work with this file included. The UI application does not work without this include.
I believe the solution is to put all JQuery Plugins into a Angular Directive (Initialising jQuery plugin (RoyalSlider) in Angular JS). This looks like a painful task.
Are there other frameworks that would work with this?
I have found some threads suggesting a ground up approach with Angular ("Thinking in AngularJS" if I have a jQuery background?), but I'm stuck with this current UI app's structure.
Suggestions? I'm thinking of using JQuery to acquire the JSON and inject it into the UI and adding Thymeleaf for its fragments.
After some research I have found that using JQuery is the way to go if your application was built with JQuery. If I could do it again, perhaps Angular should have been the base for the UI application. However,after some exploration, I have found JQuery does a lot of cool things around AJAX and Dom manipulation. When used with ThymeLeaf in Spring Boot, you end up with a power set of UI tools.

I am working in a project which is developed using AngularJS1.2, since it is older I am thinking to write feature modules in separate app using Angular and then with the help of Microfrontend thinking to combine with older app. To achieve this, I am not able to get a good source/guide. Can anyone please help me.
I see 3 ways but haven't tried any of them though. So, I don't have any working solution.
Have a route from angularjs that points to angular app(full page load) and everything from there onwards, angular handles everything. There is no angularjs involved. This may not be the best option.
Let angular code load on demand when the feature is required and provide placeholders for the angular features inside angularjs project. This way you can share custom scope to nested child angular project.
Use web components developed in angular(angular elements) and use them in your angularjs application. They work independent of technology/framework/library.
We are working on pure javaScript project, which could really benefit by using angular js but it's a huge project and re-writing the whole project in angular is not an option . Does anyone have any idea or advice about integrating angular with an existing project
Angular is a framework. It's all or nothing...you are going to rewrite everything just due to the nature of how Angular works. You can't really just 'sprinkle' some Angular on top of it because Angular controls the entire view.
It may be possible to just use Angular in a certain area of the page, but this would be a huge waste of resources (Angular minified is 143K) and make for terrible code.
Just learning , new to this site.
Is it possible to have ExtJs and AngularJS together in same application ?
or is it worth to have both of them in same application ?
Thanks
Sometimes people use ExtJs components in an AngularJS 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.
Hi I am new to AngularJS. I have great web app already running with JQuery and jQuery UI.
Now I want to completely get rid of JQuery and am going to migrate to Angularjs because of its MVC (MVW) pattern.
So my jQuery application is running with EJS for templates and entirely DOM manipulation. But when I think about Angular js, I have doubts. Can I still use EJS or not?
So please guide me whether I can use or not.
Another doubt is, let's assume I have list page. It is updated dynamically, and it will display 10 records first then based on user scroll, the next 10 records will be appended in the DOM after AJAX. Can we append to the DOM dynamically using Angular?
How do I achieve these kind of things in Angular?
You can use EJS (server or client side) in combination with Angular but there's no need and you'll probably overcomplicate things. AngularJS is very capable for manipulating the DOM by itself in a very separation of concerns kind of way. The most elegant way to work with Angular is to have a RESTful backend and just serve some static html/js files from a webserver.
As for endless scrolling, there are tons of ready to use plugins (modules) to choose from or you can write your own. Basically this will need a view with a ng-repeat directive to display the currently loaded items and a directive that will notify a controller/scope to load more items when the user is scrolling down.
A nice simple article can be found here.

Yes of course you can use EJS with Angular JS. You might want to have a look at this;
https://gist.github.com/jrmoran/4277025
And about your DOM manipulation question. Yes you can append DOM dynamically using Angular JS. Angular JS have a strong feature of two way data binding which dynamically updates its DOM content when a model variable changes.
Have a look at this:

I've built a webpage using html, css, javascript, and jquery. I just started learning Angular.js. My question is do I have to rebuild the site in order to meet certain angularJS conventions or is everything I will be adding for Angular unobtrusive to my previous built code?
It is actually recommended that you NOT use jquery with angular for starters. To get the most out of angular you will most likely have to re-architect your website. The reason for this is that Angular is a framework; jquery is a library. Their concerns are different.
When we think in Angular terms, we think about:
Views, not DOM elements
Directives, not event bindings
Models as a projection of view
Functionality separation
