Learn how to replace legacy computed properties and observers with Ember's @tracked system to eliminate dependency arrays and improve application performance.
Learn how Ember Octane's tracked properties replace implicit computed property dependencies with explicit @tracked decorators and autotracking for simpler, more reliable reactive state.
Ember's autotracking replaces hand-maintained computed-property dependency lists with runtime tracking. A worked cart example shows the pattern — and the untracked-mutation trap that causes most 'why didn't it update?' bugs.
When two or more components need to share state in Ember, services are the canonical solution. This note outlines the minimal design, data boundaries, operational checks, failure modes, and when to rethink the service‑based approach.
Stop manually managing dependencies in Ember. Learn how @tracked and autotracking eliminate the need for observers and computed properties to create high-performance, reactive UIs.
An architecture note on Ember Data's Store: the identity map, adapter/serializer trust boundaries, caching pitfalls in 5.x, and the failure modes that decide whether the classic design still fits.
Learn how to add @tracked to a component property so the template updates instantly when the value changes, with setup steps, verification tips, and recovery options.
Learn how Ember Octane’s @tracked decorator simplifies reactivity, with a step‑by‑step counter example, common pitfalls, and best‑practice tips for production code.
Ember Octane’s @tracked properties simplify component state management by eliminating manual set/get calls. This blog walks through how they work, a counter example, trade‑offs, and actionable steps to adopt them safely.
