Application Boundaries
Feature-oriented structure, clear responsibilities, shared capabilities and dependency boundaries that keep large applications understandable.
Architecture principles
Design the system, not just the components
A scalable frontend is more than a collection of reusable components. Architecture defines boundaries, ownership, dependencies and the way teams safely evolve the application over time.
Component Architecture
Reusable UI primitives, domain components, composition patterns and maintainable interfaces between presentation and application logic.
State & Data Flow
Choosing appropriate local, feature and global state patterns while keeping API integration and reactive data flows predictable.
Engineering Quality
Testing strategy, code quality, performance budgets, observability and CI/CD practices that make architecture enforceable in day-to-day delivery.
Architecture decisions
Choose patterns from constraints, not trends
Architecture should solve a product and organizational problem. The right choice depends on application size, team topology, deployment needs, domain boundaries, operational maturity and the cost of introducing additional complexity.
Monorepo vs. multiple repositories
Use repository boundaries deliberately. A monorepo can improve discoverability, shared tooling and coordinated changes; separate repositories can strengthen autonomy when teams and release lifecycles genuinely need isolation.
Modular frontend vs. microfrontends
Start with strong internal boundaries when independent deployment is not a real requirement. Microfrontends become more compelling when autonomous teams, incremental modernization or independent delivery justify the additional operational and governance complexity.
Local state vs. shared state
Keep state close to the feature that owns it unless multiple domains genuinely need the same state. Shared state should have an explicit ownership and contract rather than becoming a default application-wide dependency.
Abstraction vs. duplication
Share stable concepts and genuinely common behavior. Premature abstraction can create coupling between features that should evolve independently; deliberate duplication can sometimes be cheaper and safer.

Architecture lifecycle
From system design to delivery
Architecture decisions should remain connected to implementation and operational reality rather than becoming a document that sits outside the development workflow.
Assess
Understand business constraints, existing application structure, technical debt, team boundaries and delivery requirements.
Design
Define application boundaries, technology choices, data flow, state strategy, repository structure and integration patterns.
Implement
Turn architecture into conventions, libraries, tooling, code-quality rules and reusable patterns that teams can apply consistently.
Evolve
Measure performance and maintainability, address technical debt and adapt architecture as products, teams and requirements change.
Architecture should enable delivery.
The objective is not architectural complexity. It is a system that lets teams make changes safely, understand the impact of dependencies and continue delivering as the product grows.
Performance & quality
Architecture has runtime consequences
Architecture choices affect the browser, the build pipeline and the engineering workflow. Performance and quality should therefore be treated as architectural concerns rather than late-stage optimization tasks.
Runtime Performance
Rendering strategy, change detection, component boundaries, data fetching, code splitting, lazy loading and bundle composition.
Build Performance
Repository tooling, dependency graphs, caching, affected builds and CI optimization so architecture scales with the development organization.
Testing Strategy
Unit, component, integration and end-to-end coverage chosen according to risk, ownership and architectural boundaries rather than maximizing test count.
Maintainability
Explicit conventions, linting, type safety, dependency boundaries and documentation that keep architectural intent visible during everyday development.
