Motif - An Opinionated Dependency Injection API for Deep Graphs
summary
Motif is an opinionated DI layer that generates Dagger code and intentionally simplifies component-per-scope boilerplate, trading Dagger’s broad flexibility for a slim API. Uber reports conversion of about a hundred Dagger components and runs the app with over a thousand scopes and ~200 Android engineers, with Motif in production as a pre-release. Motif infers parent/child scope dependencies, offers full Dagger interoperability, and implements an annotation processor and IntelliJ plugin plus an IR for real‑time graph validation.
