FAQs: Node JS Development

For pure CPU work we offload to worker threads or companion Python/Go services, keeping the event loop free.

Yes — every project ships with auto-generated Swagger/OpenAPI docs and Postman collections.

We follow the strangler-fig pattern to incrementally extract services with zero downtime.

Yes, unless there's a specific reason not to — the compile-time safety consistently pays for itself on any codebase expected to live more than a few months.

Through a dedicated job queue (BullMQ or a managed equivalent) so slow work never blocks the API response cycle, with automatic retries on failure.

We build explicit timeouts, retries with backoff, and circuit breakers around every external call so one failing dependency doesn't cascade into a full outage.

It depends on traffic patterns — serverless suits spiky or infrequent workloads, while containers suit steady, predictable traffic with more operational control.

Based on how your frontend actually consumes data — REST for simplicity and caching, GraphQL when clients genuinely need flexible, minimized data fetching.

We prioritize thorough coverage of critical business logic and payment or auth flows over chasing a coverage percentage across trivial code.

Both models work — a scoped build with handoff documentation, or an ongoing retainer for continued feature development and maintenance, based on what your team actually needs.

Both — we regularly audit and improve existing legacy codebases, not just start new projects from scratch, and often begin with a targeted performance and security review.
