Strengths & Weaknesses

↑ Strengths

Minimalistic design for high performancemedium

Asynchronous request handlingmedium

Lightweight and easy to integratemedium

↓ Weaknesses

Limited language support beyond JavaScripthigh

Primary focus on JavaScript limits its utility for polyglot microservices architectures.

Poor documentation and community supportmedium

Official docs are sparse, with limited examples and tutorials; community forums have low activity.

Complex setup for non-trivial applicationshigh

Configuring services, dependencies, and external integrations can be cumbersome without comprehensive guides.

Performance degradation under heavy loadmedium

Asynchronous handling may lead to performance bottlenecks when dealing with a large number of concurrent requests or complex operations.
