When Clients Call Us Urgently

If one of these sounds familiar, this is where we step in.

We start with an audit of the code, dependencies, and deployment setup, then give you a written plan.

Your API Slows Down Under Load

Blocking code, missing indexes, and chatty database calls are the usual causes. We profile the event loop, fix the hot paths, add caching, and move slow jobs to queues. Slow APIs make every app on top of them feel broken.

Async Bugs Cause Random Failures

Unhandled promises, race conditions, and swallowed errors show up as flaky behavior in production. We add structured error handling, logging, and tests around the risky flows. Random failures cost customer trust and support hours.

It Works on One Machine but Not in Production

Environment drift and manual deploys cause surprise outages. We containerize the service, add CI/CD, and separate configuration from code. Outages hit your customers first.

An Old Node Version or Package Is a Security Risk

Unsupported runtimes and outdated dependencies leave known vulnerabilities open. We upgrade in stages, audit packages, and pin what matters. Known holes put your customers’ data at risk.

NodeJS Development Services

Six kinds of Node.js web development we deliver, from new back ends to rescues.

Custom Node.js Applications

APIs and back ends in TypeScript with Express or NestJS, built around your data and rules.

Real-Time Applications

Chat, live tracking, notifications, and dashboards that push updates over WebSockets.

REST and GraphQL APIs

Documented, versioned APIs for web and mobile front ends.

Integrations and Microservices

Payment, ERP, and third-party connections, plus splitting a growing system into services where it pays off. See microservices development.

Containers and Deployment

Docker images, CI/CD pipelines, and cloud deployment. See DevOps containerization.

Testing, Upgrades, and Support

Automated tests, Node version upgrades, monitoring, and fixes on a monthly retainer or on demand.

Why Build Your Back End on Node.js?

One Language Across the Stack

Front-end and back-end teams share JavaScript or TypeScript, types, and validation rules.

A Large Package Registry

npm offers maintained libraries for authentication, payments, queues, and more.

A Natural Fit for Real-Time Features

WebSockets and event-driven code are first-class in the Node.js world.

Architecture Plan

We choose the framework, database, queues, and hosting, and document the decisions.

Build in Sprints

Endpoints, business logic, and automated tests ship together in short sprints.

Test and Harden

Load tests, security checks, and dependency audits before release.

Deploy and Monitor

CI/CD deployment, logging, alerts, and support after launch. Button: Book a Consultation Bring your requirements or your existing service and we will map it to these steps.

FAQs

How Much Does Node.js Development Cost?

Cost depends on the number of endpoints, business rules, integrations, real-time needs, testing depth, and hosting setup. A new API costs differently from a rescue of an existing service. We scope each project individually and send an itemized proposal after a consultation.

How Long Does a Node.js Back End Take to Build?

It depends on the number of endpoints, business rules, integrations, and real-time needs. We give a timeline after scoping and split it into milestones, so you can call working endpoints early. A focused API ships sooner than a full platform.

How Will We Follow Progress on a Back-End Project?

You get documented endpoints and a staging API you can call after each sprint, so your front-end team can start integrating early. We agree overlap hours at kickoff and report through Slack, email, and video calls. Syndell has offices in Middletown, Delaware, Manchester, UK, and Ahmedabad, India.

Should We Use Express, NestJS, or Fastify?

Express suits small services and quick APIs. NestJS suits large teams and long-lived back ends that need structure. Fastify suits high-throughput APIs with strict validation. Many projects fit more than one, so we decide after reviewing your team, size, and performance needs.

Is Node.js Good for Enterprise Back Ends?

Yes, for API-heavy and real-time systems, and for teams that share TypeScript across front end and back end. It is a weaker fit for long CPU-heavy calculations, which we move to worker threads or separate services. We flag these limits during scoping.

Can You Build a Back End in Node.js for Our React App?

Yes. React and Node.js share one language, which makes shared types and validation easy. We built Fleet Management and Furniture Manufacturing with React and Node.js. Our ReactJS team builds the front end while the Node.js team builds the API, so both sides stay in step.

Can You Take Over or Upgrade an Existing Node.js Service?

Yes. We start with an audit of the code, dependencies, tests, and deployment, then recommend whether to fix, upgrade in stages, or rebuild. You get the recommendation in writing before we change production code, so you can weigh cost and risk for each option before you decide.
