Do you have any pattern that solves a CSRF Violation when you need to perform a DML operation through a connected callback? We have been flagged in the security review regarding this, but we cannot easily find good examples how to solve this.

Hi, why we can't we use constructor to fetch the data through apex ? as per the documentation, connectedcallback is always used to initilaize the data.

What VS Code extension do you recommend for Static Code Analysis for LWC? ESLint?

when should I use the connectedCallback() instead of the wire decorator for fetching records that are dependant on public properties? Usually my goto is the wire decorator.
