LWC ArchitecturePro
A Sluggish Service Console LWC
3 decision points870 grounded questions
The scenario
On the Service Console, a Case page hosts a customer-summary LWC, a related-cases list, and a utility-bar component. Agents report stale data after they edit a record, the same Apex runs several times per page, and the related list stutters when an account has thousands of cases. Make it fast and correct.
Constraints to satisfy
- Data must refresh after a mutation without a full reload.
- Avoid redundant server round-trips.
- The long list must scroll smoothly on large accounts and on mobile.
- Cross-component refresh must work even with no DOM relationship.
Think through your own design first - data model, timing, failure modes. Then walk the decision points and defend each choice against a worked architecture.
