    Building Angular Apps with NgRx

    In complex projects it is necessary to define a strategy to manipulate the state of our application. Let's review what NgRx is (called the mystical machine), how it helps us make our implementations easier (and solve errors faster).

    Angular Fundamentals

    We listen and read, in blogs, social networks, etc., more and more terms like: web applications, mobile apps, developments responsive, javascript frameworks, full stack developers, backend and frontend. You have to start modeling a professional profile and it is best to try to know all the edges by which you can walk in a profession like ours. That is why we will be showing you a technology that includes many of these terms we listed before: Angular.

    What is Angular? What is this for? How can we start a project with this framework? We will share basic concepts about the framework like:

    • Components
    • Modules
    • Directives
    • Services (DI)

    Finally, we will build an app and run it live.

    Angular Architecture Planning

    We have to plan and design our application and it is time to make many decisions and prioritize. We know that our business is complex and it is important to balance the technical decisions and requirements of our client.

    How do I start? What is the simplest way to organize our project? How do I define my components / services? Which stage management strategy is best for my need? How do I avoid overkill? The unit test? Do we add Automation tests? And the security? Local logging, in the cloud or both?

    We will share different experiences and alternatives based on our needs to make the best decisions
