Can a component be declared in multiple modules?

If any component can be reused within multiple features, we can declare it inside a shared module. Services and Pipes are the most common usages for shared modules. For anything which might be used across all feature modules, we can just declare it in the CoreModule.

How do you display one component in another component?

How to nest a component inside another component in angular?

1. Step1: Open the “app. module. ts” file which is present inside the app folder, and then do the following things.

Which is the best example of a module?

Examples include UI controls and “background components” such as timers, threading assistants etc. A “module” is a larger piece of the whole, usually something that performs a complex primary function without outside interference. It could be the class library of an application that provides integration with e-mail or the database.

Is there a difference between a component and a module?

In non-computer terms, a “component” may be the engine block of a car; you can tinker within the engine, even replace it entirely, but the car must have an engine, and it must conform to very rigid specifications such as dimensions, weight, mounting points, etc in order to replace the “stock” engine which the car was originally designed to have.

If you are getting codes for a faulty oxygen sensor, for example, and you have replaced all the related components but the check engine light remains illuminated, then you may have a bad PCM. The ECU is responsible for many areas of the vehicle that control whether or not the vehicle starts.
