Angular Component Patterns: The Smart and Dumb Components

In Angular, it's common to create two types of components: smart and dumb components. A smart component is a component that is responsible for handling business logic, making decisions, and communicating with services. It typically has more complex logic and is often used to orchestrate the behavior of multiple dumb components.

Smart components may retrieve data from services or other sources, perform calculations or transformations on the data, and determine how the data is presented to the user. They may also receive and respond to user input, and may communicate with other components or services to accomplish their tasks.

By separating the responsibilities of smart and dumb components, you can create more modular, maintainable, and reusable code in your Angular application. Smart components can be thought of as the "brains" of the application, while dumb components are the "hands" that simply display data and respond to user input.

A dumb component is a component that is responsible for displaying data and responding to user input, but does not have any business logic or knowledge of the data it is displaying. Its sole purpose is to present data in a visually appealing way to the user.

Dumb components are typically simple, reusable, and modular, and can be composed together to create more complex UIs. They often receive data from their parent component through inputs, and emit events to their parent component through outputs when the user interacts with them.

By separating the responsibilities of smart and dumb components, you can create more maintainable, reusable, and testable code in your Angular application. Smart components handle the business logic and orchestration, while dumb components focus on presentation and user interaction.

wow! super cool! I was dreading if this would be complex but you made it a breeze! thanks

If you have multiple Input coming from smart component its so hard to handle them if they depend on one another. You cannot put: wait for Input variable 1 to be received then handle received Input variable 2.
