Node.js

Node.js development for product APIs and real-time features

We use Node.js with TypeScript for product APIs, SaaS backends, and integrations where the same language as the front-end team is an advantage. The runtime is fast to ship. The discipline around types, tests, and process management is what keeps it operable.

  • SaaS application servers
  • Integration workers

What we build

HTTP APIs, webhook receivers, and the application server behind React or Angular. Real-time updates are added when the product truly needs them, with a clear story for reconnection. TypeScript is the default so a refactor does not depend on hope.

When we look elsewhere

CPU-heavy processing and some high-throughput network services are a better fit for Go or for a worker in another language. A long-running enterprise domain inside a Java house should not be pulled into Node.js only because the front-end developers prefer it.

Node when the product is the web

Fits

  • APIs next to a JavaScript front end
  • Realtime or integration glue
  • A team that already ships JavaScript

Look elsewhere

  • Heavy long-running calculation as the core
  • A team with no JavaScript operators
  • A second backend for fashion

What changes a Node service

01

One language

Sharing types with the front end is a real saving. It is not a reason to put everything in one process.

02

The load

Say what must be fast. Node is not a slogan for every workload.

03

The modules

Dependencies are part of the security work, not an install step.

Before a Node service

  1. 01

    The front end

    Whether sharing a language with the UI is a real saving.

  2. 02

    The load

    What must be fast, in a sentence.

  3. 03

    The process

    What stays out of this process.

  4. 04

    Dependencies

    Who will keep the modules current.

Marks Node is carrying the right work

  1. 01

    A shared reason

    The API and the web use it because one team owns both, or the integration needs it.

  2. 02

    Long work is elsewhere

    A slow task does not sit inside the request the user is waiting on.

  3. 03

    Errors are logged

    A failed call can be found with the input that caused it.

  4. 04

    The runtime is fixed

    Production runs a named Node version, the same one the tests use.

What we build

TypeScript APIs

Contracts, validation, and authorization that fail in tests rather than in production.

SaaS application servers

Tenancy and roles on the server, never only in the UI.

Integration workers

Queues and retries for webhooks and partner calls.

Shared types

A careful share of models with the front end, without coupling to database rows.

Questions we hear

Do you write Node.js in plain JavaScript?

Only when we are maintaining an existing codebase. New work is TypeScript.

Is Node.js acceptable for a serious system?

Yes, if the team operates it properly. The language does not remove the need for backups, limits, and tests. It also does not disqualify the system.

Can you use Nest or Express?

Either, chosen for the size of the service and the team. The framework is not the architecture.
