Apex, LWC and Flow: choosing the right Salesforce architecture

Balancing declarative automation and custom code for maintainable Salesforce solutions.

The right Salesforce tool depends on risk, scale and maintainability. Straightforward record automation fits Flow, while complex transaction logic and high-volume processing may require Apex.

Lightning Web Components provide task-focused experiences when standard pages are insufficient. Components should remain small, reusable and accessible.

Governor limits, bulk behavior and the sharing model belong in every design decision. Apex tests should protect business behavior rather than merely reach a coverage number.

A sound architecture separates the responsibilities of Flow, Apex and LWC, reducing technical debt and making future releases safer.
