Hello, developers! Today, let’s talk about the pros and cons of Angular development.
The Angular framework remains the best solution if you need an interactive application that will function adequately on any device. If the task is to create a landing page, the development of the site on the corner will solve it quickly.
Angular has a really huge audience of developers and there are a lot of reasons why they love creating applications on it so much. A well-designed application will be a new channel of communication for your business. Your own site will increase customer loyalty and the trust of partners. Thoughtful design and pleasant design of the interface will quickly lead your potential customer to the target action.
If you have chosen a team of Angular developers, be sure that they will be responsible and dedicated. Most often, they continue to run the application in a technical support format and are ready to provide a team for a custom product. The team also helps to improve the product: they always think about updates and improvements.
Each team of Angular developers has a market manager that is always aware of the selling side of the development. The team of marketers can start promoting the site on Angular at any time. Marketers will create an effective strategy for maximum conversion of CA, and effective communication with already attracted customers. If you do this during development, the market will already be waiting for your web service: the audience will be prepared, and potential customers will be ready to buy.

What are the pros of creating an application or a website on Angular?
The Angular framework was released in 2010 by a team from Google, which means support for the largest search engine. In addition, Angular sites have a number of other advantages: The framework has reliable support. In addition to the global corporation Google, there are a large number of tools that are already optimized for the platform or are in the process of optimization, which simplifies the development process. Developers know the framework. When it is a familiar platform, the creation of the site is faster, which will affect the total cost of the product. Reliability of the framework.
The Google team follows the traditions of its corporation, so it strives for a smooth and even development of the platform. There are no tools that do not work. Before launching the new version, it is tested on hundreds of other projects. Angular is definitely smart. The framework automatically adjusts the default settings for standard tools, such as language selection. This improves the efficiency of writing code.
Does Angular app development take a lot of time?
The framework often writes an application with a user-rich interface (RIA). This is faster, but the time of creating a web-resource is also influenced by the specifics of the topic, the complexity of the logic, the uniqueness of the design, and other nuances. It is possible to estimate the terms of the project only in the presence of a vehicle with an indication of the functionality. If you have an idea for a web project, leave an order to the manager of any Angular company and they will contact you.
How much does it cost to create an app with the help of Angular?

Because the site onAngular is created on the basis of a complex and powerful framework, the cost will be less than for a self-written application. However, it is difficult to say the exact cost without a clear technical task. The average hourly rate of Angular developers is $30-40.
Actually, with all its features like two-way data binding, great community support, and possibility to create apps with very rich functionality, it is worth using it. But everything has its dark sides. What are the cons of Angular development? Let’s figure this out.
Framework
Frames are always creating some limits. With Backbone and jQuery, you could write the code that you want, where the main thing is that it works. With Angular, you have to go deep into the jungle of settings so that everything is according to the rules. It’s good that the app follows the rules. It’s bad that there is too much documentation.
Declarative programming
The code that binds the DOM with the logic has moved completely to HTML. jQuery style selectors are almost unnecessary. This severely limits the framework’s usability with existing scripts and running systems. An attempt to connect two worlds and use some jQuery events from the ng-controller will look like a hack.
All events are hung on the element itself. This is somewhat good (less code in JS), but on the other hand, it sprays the visibility of the entire application and binds HTML to logic more tightly. For example, it is now easier to show elements with ng-show, but when you have ng-class, ng-src, ng-repeat, ng-click, and a dozen more directives, including self-written ones, on your element, it becomes difficult not only to read HTML but also to understand the states to which the element can come or the order of events.
Model bind problem

The DOM update problem is still there. Models are ordinary objects in which the $$ hash key parameter is hidden, by which a two-way DOM update is bound. The problem is that with your logic you can break models so that they lose this key and then the DOM will live its own life, and you will not notice it. This is the most difficult bug to catch.
Most often, the loss happens due to the fact that you have a local data cache in memory (model), which is updated asynchronously via $ HTTP, but you are using an assignment to update.
For example, in the controller, you bind the view to the cached data from the service:
$ scope.user = UserService.getUser (); UserService.updateCache ();
If your service just overwrites the internal variable, it won’t update the view.
UserService = [‘$ http’, function ($ http) {var _localUserCache; return {updateCache: function () {$ http.get (‘user’). then (function (response) {_localUserCache = response.user;}); }, getUser: function () {return _localUserCache; }}}]
This is due to the fact that in javascript data is passed by reference, but if you assign a new value, the old value (which is assigned in the view) will remain in memory, but new data will also be created. Therefore it is correct to use this:
angular.copy: angular.copy (response.user, _localUserCache);
The second common source of model binding is removing items from collections. They should be done with array.slice, not with the undefined or delete keyword.
Escaping and quotes

Escaping is built-in in the Angular – you can’t just spit out HTML from the filter. This is good from a security point of view, but on the other hand, it is a long-term problem. You must use $ sce.trustAsHtml (). But I’m not even complaining about that.
Let’s say you have translations as a filter. Do you want to insert a link into translations? How will you transmit it?
{‘text_with_link’: “click me!”, ‘text_with_vars: “{{start_tag}} clickme! {{end_tag}}”}
Have you noticed the escaping quotes? And this is external, pure JSON. In general, escaping quotes inside real HTML is a disaster.
Finally, Angular doesn’t develop a programming language for the sake of a language. You don’t need classes, prototypes, hierarchies, inheritance, public-private methods. Connect dependencies, inject scope and necessary services and write a controller. This is a kind of degradation for the sake of efficiency.
Conclusion

Well, that’s it. It may seem that there are more disadvantages than advantages, but that’s not true. From my point of view, Angular is a perfect option for software development. On the plus side, I liked the directives. The fact that you can define a visually isolated element as a brick makes it convenient for the layout of any WYSIWYG, combo boxes, calendars, etc. I liked the magic with auto-update of view-models, with translation and with dependency-injection of components just by the name of the service.
