Hey guys, today in this post we are going to learn about How to Fetch current Record Id and show selected recordId on the page on click button functionality in Lightning Web Component – LWC.
Each record in the Salesforce.com system has a unique ID field assigned to it which is known as Record ID.
It is system generated and cannot be edited or deleted.
It is generated every time a new record is inserted into the application.
Add the force:hasRecordId interface to an Aura component to enable the component to be assigned the ID of the current record. The current record ID is useful if the component is used on a Lightning record page, as an object-specific custom action or action override in Lightning Experience or the Salesforce mobile app, and so on. This interface has no effect except when used within Lightning Experience, the Salesforce mobile app, and Aura-based Experience Builder sites.

How do you get record ID and object name in LWC?
To get the current Record Id and Object API Name, we have to declare the respective properties with @api annotation just like @api recordId, @api objectApiName and we need to place the component into Lightning Record Page.
What are the two ways to get the record id?
There are two ways to find them: Go to the Record Type (Setup> Customize> (object)> Record Types). Click on the record type. Find the Record Type ID in the URL between id= and &type.
What is the use of @wire in LWC?
Wiring a property with @wire is useful when you want to consume the data or error. If the property decorated with @wire is used as an attribute in the template and its value changes, the wire service provisions(requests) the data and triggers the component to rerender.
