Case study
Frontend architecture / Open source
Angular Enterprise Architecture

The condition
Challenge
Large Angular codebases erode when dependencies, state ownership, change detection, and team boundaries remain conventions rather than enforceable architecture.
The response
Architecture
An Nx monorepo uses scope and type tags, standalone components, lint-enforced boundaries, documented state choices, and a shell-plus-remote Module Federation topology.
What shaped it
Key decisions
Boundaries as code
Nx tags and ESLint rules prevent features, UI libraries, data access, and HTTP concerns from crossing defined layers.
State by requirement
Signals handle local linear flows; NgRx is reserved for shared, rollback-capable, auditable state.
Federation with failure boundaries
A dynamic manifest registers remotes without hard-coded URLs, and the shell degrades gracefully when a remote is unavailable.
How it feels
Experience
The reference contrasts local signal state with rollback-capable NgRx state, renders 10,000 activity rows through virtual scroll, and falls back gracefully when a federated remote is unavailable.
What resolved
Outcome
A public MIT reference architecture with five accepted ADRs, unit and end-to-end testing, Storybook documentation, and a published v0.1.0 release.
