Utilizing model props to drill down and access or set the state on desired components is the least complex approach for sharing information between Single Page Application (SPA) components in AEM.
Here's why using model props is effective:
* Simplicity: This approach leverages the existing component hierarchy and properties, making it straightforward to pass data between components.
* Direct Access: Model props allow for direct access to the state and properties of parent or sibling components, enabling easy data sharing.
* Minimal Setup: Unlike implementing a state library or customizing container components, using model props requires minimal additional setup, reducing complexity and potential overhead.
Steps to utilize model props for state management:
* Define the State in the Parent Component: Ensure that the parent component maintains the state that needs to be shared.
* Pass Props to Child Components: Pass the necessary state and any setter functions as props to the child components. For example, in a React-based SPA, you can do this using JSX syntax:
function ParentComponent() {
const [sharedState, setSharedState] = useState(initialState);
return (
<ChildComponentA sharedState={sharedState} setSharedState={setSharedState} />
<ChildComponentB sharedState={sharedState} setSharedState={setSharedState} /> );
}
Access and Modify State in Child Components: In the child components, access and modify the shared state using the props passed from the parent:
function ChildComponentA({ sharedState, setSharedState }) {
return (
<div>
{sharedState}
<button onClick={() => setSharedState(newState)}>Update State</button>
</div>
);
}
By using this approach, you ensure a simple and effective way of managing and sharing state across components in your SPA, adhering to best practices for component-based architecture.
