Managing Focus in Angular: Dialogs, Drawers and Route Changes Without Stranding Your Users

Short summary

A detailed guide to focus management in Angular SPAs covering route changes, dialogs, drawers, and destructive actions. The core mental model: focus is a single cursor and every UI state change must deliberately place it somewhere useful. Practical fixes include moving focus to page headings on navigation, trapping focus in modals via CDK, and restoring focus to triggers on close.

• •Route changes in SPAs leave focus on dead elements — move it to the new page heading
• •Dialogs must trap focus while open and return it to the trigger on close
• •Destructive actions need explicit focus relocation after DOM updates using afterNextRender
