Angular2 - how can I effectively organize the logic between my components and services?

Within my current project setup, I have the following structure implemented:

I have a Component that interacts with a Service Class which in turn calls an external API. The specific logic that I need to implement is related solely to the user interface.

While this setup is relatively simple and clear, I find myself in a situation where I need to incorporate additional binding and logic. Consequently, I ended up adding it directly within the Component itself, which doesn't seem like the most optimal solution. I am contemplating creating a middle ground between the Component and Service Class to handle this task separately. Do you think this approach is advisable? What would be considered the best practice for handling this scenario?

Thank you.

Answer №1

Typically, when dealing with an object, a service, a component, and a class are all that is necessary.

The component should handle the UI elements and connect to services, while the service should focus on functionality without knowledge of the UI (often used for API calls).

In certain situations, it might be suitable to create a /util.ts file to store reusable functions, although this is not always recommended. These functions cannot be tied to any specific component or service.

If additional abstraction is needed for specific fields, especially when a component becomes overloaded with responsibilities, creating another module and using EventEmitter and properties to exchange data is a good approach. For more information, refer to the documentation.

Edit:

For further guidance on best practices, it is recommended to review John Papa's Angular2 style guide. Following principles such as single responsibility and maintaining app structure will help ensure code quality.

Answer №2

In Angular 2, it's typically the components where logic for bindings should be placed.
