REST API Development
APIs designed with a clear contract, versioning, and documentation.
- Express, Fastify, or NestJS
- OpenAPI specification
- Versioning and deprecation strategy
🟩 Development
Backend Services Built for Throughput and Handover
Node.js suits API and integration workloads that spend their time waiting on other systems. RASPSYS builds those services with the testing, logging, and documentation that make them supportable.
What We Deliver
What We Deliver With Node.js
Node is excellent at I/O-bound work and poor at CPU-bound work. Picking it for the right reason is most of the architectural decision.
Integration Middleware
Services that sit between platforms and translate, queue, and retry.
- Payload transformation
- Queueing and retry logic
- Idempotent request handling
Real-Time Services
WebSocket and event-driven services where polling is not good enough.
- WebSocket and SSE endpoints
- Event-driven architecture
- Pub/sub integration
Salesforce Connectivity
Middleware connecting Salesforce to systems it cannot reach directly.
- REST and Bulk API clients
- Platform Event consumers
- Governor-limit-aware batching
Security & Auth
Authentication and authorisation built correctly rather than improvised.
- OAuth 2.0 and JWT
- Secret management
- Input validation and rate limiting
Deployment & Observability
Containerised, monitored, and documented for operations.
- Docker and CI/CD pipelines
- Structured logging and metrics
- Health checks and alerting
How We Work
Our Node.js Delivery Approach
A structured engagement model that de-risks delivery and gets working functionality into your team's hands early.
-
Define
We agree the API contract and non-functional requirements first.
-
Architect
Service design, data flow, and failure behaviour.
-
Build
Implementation with automated tests alongside.
-
Harden
Load, failure, and security testing before release.
-
Operate
Monitoring, support, and iterative extension.
Not Sure Node.js Is the Right Fit?

FAQs
Frequently Asked Questions
The questions we are asked most often about Node.js.
Node handles many concurrent I/O-bound operations efficiently on a single thread, which suits integration middleware and API gateways well. Python is often better where data processing or ML libraries matter; Java or .NET where you have existing platform investment and deep enterprise tooling. We choose per workload rather than by default.
For I/O-bound work - API calls, database queries, message passing - yes, and comfortably. The caveat is CPU-bound work: heavy computation blocks the event loop and throughput collapses. If your workload has that shape we would either isolate it into worker threads or recommend a different runtime.
By default, yes. For anything that will be maintained beyond the initial delivery, static typing pays for itself quickly in refactoring safety and editor tooling. We will work in plain JavaScript if that is your team standard, but we will make the case for TypeScript first.
Containerised, with configuration externalised and secrets injected at runtime. We set up CI/CD to whatever your team already uses. Health check endpoints, structured logging, and metrics are part of the build rather than added afterwards.
