Convention Over Configuration Framework

A productive, battle-tested JavaScript framework for building modern web applications that includes everything needed to create rich user interfaces working across any device, with a convention-over-configuration philosophy that reduces boilerplate and decision fatigue. Major organizations including streaming platforms, customer support tools, cloud infrastructure providers, cybersecurity companies, and technology giants have been iterating on their products for years using this framework. The batteries-included architecture provides a built-in build pipeline through its CLI tool, which offers code generators for creating new components, routes, models, and tests, placing files in conventional locations automatically. A built-in development server provides fast rebuilds with live reload, and a test runner executes unit, integration, and rendering tests. The framework's router is widely regarded as best-in-class, incorporating asynchronous data loading with dynamic URL segments, query parameters, nested routes, and loading and error substates. The data layer provides a model abstraction with relationships, automatic cache management, adapter patterns for connecting to any API backend, and built-in optimistic updates. The Glimmer rendering engine compiles templates to highly optimized virtual machine instructions, achieving rendering performance competitive with hand-optimized vanilla DOM manipulation. Addons extend functionality with pre-built UI components, authentication systems, internationalization, animation libraries, and testing utilities. The framework enforces testing as a first-class concern with built-in support for QUnit, Mocha, or Jest integration tests, and the CLI generates test stubs for every new entity created. Convention-based file structure means developers can move between projects and immediately understand where code lives.
