![]() Since the angular architecture is built around the dependency injection style of architecture it really helps in doing test-driven development which is all the buzzword these days. It provides all these features using ahead of time compilation concept -:Įffective security against injection or cross-site scriptingħ. Super ease of testing frontend angular applications Most systems built by google feature a really well thought out CI/CD flow. Since users can quickly make apps, test them, see the changes in real-time getting reflected in the browser. It almost takes no time to spin up a full-fledged angular application and with a daemon server running in the background you can do iterative development. ![]() Source: 6. Ease of prototyping and iterative development supportĪngular provides one of the fastest startup times to write a minimum viable app. Overall Architecture Diagram Showcasing how the angular architecture is built. It is modeled to take care of the inherent hierarchies in your application as you build them out using the other components and built around the conventions/principles of how browser navigation works for end-users. One of the smart features though provided in this is called lazy loading, where the router can load the module on demand and doesn’t have to do all the wiring at initialization, as in older routing architectures. This part of the architecture layer handles piping the URL to the view. Routing classes are where all the URL direction, plumbing, and re-direction are handled. In angular, you can create a service class and use its decorator to inject dependencies into your classes. ![]() It enables code residing inside components to be lean, agile, mockable, making testing easy.Įnables developers to add and remove functionality from an application. Service and dependency injectionĪngular architecture follows age-old principles of inversion of control via using dependency injection as a mechanism to do all the logic wiring across its components, making for a very loosely coupled architecture. Template directives: Responsible for program logic, used with binding markups or angular keywords.Įvent binding: Angular supports two-way event binding where changes reflected in your application code or inside HTML dom get reflected at both places. Think of one as a hero and the other as its sidekick. Remember templates live inside angular components. ![]() Templates are parts of the angular ecosystem that bind the Html in your front-end application with angular keywords or angular markups. You may also like Top 30 Interview Questions and Answers on Angular 5 c. Generally, every component of a class associates with one HTML template and serves to bind functionality for it. Components are like independent pieces of modules which can beĭependency injected into one another and developers can think of them as namespaces that hold the controller side logic in it for a part of the application. ComponentsĪngular has several components which connect the dom with the “root component”. To give an analogy think of the modules as an orchestrator of an ensemble. To give an analogy think of this part as the layer at which all the wiring is done. Root module or Application module, which acts as the entry point where everything is orchestrated and bootstrapped. ModulesĪngular NGModules are where developers define the entire domain, workflow, and specific capabilities for an application. Some of the top-level components of the architecture are as follows: a. The basic building block of angular is NGModules which provides all the functionalities done for users to use while developing their applications. Angular is a web framework written in typescript ( type-safe JavaScript ), which implements some of the core libraries and functionalities which users can then import into their applications.
