Our Team has been using AngularJS for a while now, and it has been the best learning curve. We want to share some knowledge to experience as well freshers who want to start their career as an AngularJS developers. we have learned and improved very much and sharing our knowledge which will help you to start your AngularJS application on the right foot! Learn from our experiences. This article has no purpose of setting rules or having the specific agenda but only to give some useful tips and tricks to learned while developing AngularJS Development Services. These are some best practices for AngularJS applications separated into five categories: Structure: When client approach for building an AngularJS application sometimes we don’t know exactly how to organize our data or even don’t know what data we might need. For this, the AngularJS team recommends two solutions: Always start with angular-seed, which is basically a backbone of a dynamic AngularJS applications. You just need to clone the repository and you are ready for development. The other recommendation is to try Yeoman (http://yeoman.io/) which is a tool that will basically create the backbone and add other tools such as grunt and bower, which are heavily used in the development of JavaScript applications. You need to be very cautious while using these tools that they seem to be very useful in the beginning. Why is so? First, you need to analyze your requirements.For example- we have a folder named ‘JS’ with all our JavaScript files like ‘controllers.js’, ‘services.js’, etc. inside just like angular-seed will create a folder named ‘app’ where all the static deployable files are and inside. It depends on the behavior of an application, sometimes there will be cases in which it is better to separate files for what they mean for the business rather having them for what kind of component they are inside the framework we are using. For example, while building an E-commerce module we could have files like ‘product-controller.js’ or ‘product-service.js’ and have folders inside our ‘JS’ folder with the modules of the business. Dependency Injection: The AngularJS injector is powerful if used wisely. Mainly used for creating components, and for resolving their dependencies and submitting the components when required. What benefits do we have when we use it? While writing tests for our application. In every component we create, following the AngularJS syntax, we require other components and it will take care of resolving these dependencies for our framework, then while creating our scripts just simply create these same components with dependencies created by us then we will be able to achieve best unit test for our application and will get good test coverage. Extension of the HTML The makers and developers of AngularJS have clarified since the starting that AngularJS is not a framework to compose code that alters the DOM. Generally, we can discover different ways when we need to do this and AngularJS shows us that the expansion of the HTML is the appropriate response. How would we achieve this? Through Directives. Particularly individuals that have worked before with JavaScript flawless with different libraries like jQuery, need to make conduct in the DOM with JavaScript. For this situation, AngularJS as of now has numerous orders that can help us to not rehash the wheel, and in the event that we don't discover something that meets our necessities, AngularJS welcome us to make our own orders where the DOM control would go. The advantages of doing as such are to have a solitary place where our DOM control code is and furthermore, to have the capacity to unit test every one of these orders, since in many events heaps of JavaScript code is not tried in light of the fact that is difficult to test modules that include the DOM. Scope With respect to object scope that we have in AngularJS, we have three basic guidelines: 1) the extension must be composed just in the controllers, implying that the controller is responsible for utilizing another segment, similar to an administration, to get the information that the template will appear and compose this information in an object of the degree. 2) the extension must be perused just in the templates, implying that regardless of the possibility that AngularJS enables us to compose code that adjusts the degree in the templates, it's something that we should be extremely careful about and likely shouldn't do. 3) don't make properties in the extension yet object! It's a typical oversight to imagine that the degree is the model segment that AngularJS discusses. Truth be told, the extension is only an approach to tie our model with the template, so the model must be a JavaScript object, to utilize a basic property can and will give issues later on with the degree chain of command. Modules In some cases when we begin to work with AngularJS we believe is a smart thought to make diverse modules, for instance, for our controllers, administrations, orders, and so on. however, this may not be the best choice. For instance: suppose we make a controller inside a module named "myapp. controllers" and this segment relies on upon an administration that is inside the module 'myapp.services'. When we need to utilize that controller in another application we won't just require the controller module yet the administration one as well and some other module that is as a reliance. Be that as it may, in the event that we have a login module and we make controllers, administrations, mandates, and so forth under the module 'myapp.login', at that point later on, when we need to utilize that module we will have all that we have to use to it without requiring different conditions.
