Custom enterprise apps

React, Node.js & TypeScript

The most common stack for modern web apps, portals and APIs.

  • Web front end and back end
  • Typical project: 3–6 months
  • Open source (React from Meta; Node.js from the OpenJS Foundation)

Overview

React builds interactive interfaces from reusable components, and Next.js adds routing and server rendering. Node.js runs JavaScript on the server, so one language, TypeScript, covers the whole app.

It is the default for customer portals, dashboards and SaaS-style products, with the biggest pool of front-end developers. Enterprises pair it with a design system so every app looks and behaves the same.

Names you'll meet

  • React
  • Node.js
  • Next.js
  • Angular

Is it right for you?

Best for

  • Customer and partner portals
  • Rich, interactive internal tools
  • Teams that ship every week

Think twice if…

  • The back end does heavy number-crunching; Java, .NET or Go may fit better
  • Nobody will keep dependencies up to date; the ecosystem moves fast

Typical projects

  1. Customer portal3–6 months
  2. Design system6–16 weeks
  3. Front-end modernisation (e.g. AngularJS to React)3–8 months

Typical ranges, not quotes. Scope, data and team size move them most.

Roles you'll hire

  • Front-end developer (React)
  • Full-stack developer (TypeScript)
