Before generative AI filled our world with bloated texts, humans relied on grammatically indifferent, terse notes to help others—and themselves—navigate the vast sea of software development. Here’s what I deemed essential about Ember, drawn from a note unearthed years ago:

• ember-data is an ORM-ish persistence layer that Ember uses by default. It uses models, adapters, serializers, and a store as it's fundamental concepts. When an API is not a good fit for ember-data, it's possible to use an ad-hoc REST endpoint or RPC-style endpoint.
• The store returns resources wrapped in "promise objects". These proxies allow the resources to be lazy loaded and trigger fetches when accessing a relationship that isn't loaded. Doing this in a loop is what causes N+1 queries.
• Ember templates use data binding to automatically re-render portions of the DOM when the backing model changes.
• Ember apps are "single page applications". The web server returns a static HTML page for all incoming requests and once the JavaScript is loaded the request is routed through Ember components which make API calls to one of our myriad microservices.
• Components are the UI abstraction ember provides, which combine a template and a JavaScript file. Ember also provides for a dependency injection container, services (singletons managed by the container), routes, and so on.
