JavaScript development for modern web and Node backends.
We ship JavaScript — and TypeScript — across the stack: browser, Node, edge, workers. Clean modules, strict types, real tests, measurable performance.
JavaScript development is the engineering of web applications using the JavaScript language (and its strict superset TypeScript) across browsers, Node servers and edge runtimes — powering frontends, APIs and tooling with a single language.
What we deliver with JavaScript Development Services.
Fastify, NestJS, tRPC — type-safe contracts and tested domain logic.
Next.js, Remix or SvelteKit with shared types end-to-end.
Embeddable JS SDKs with small bundles and clean APIs.
Cloudflare Workers, Vercel Edge, low-latency APIs worldwide.
jQuery, Backbone, AngularJS migrations to React or Svelte.
Honest fit check.
A plain answer up front. We'd rather not sell you something you don't need.
- You want a single language (TypeScript) across frontend and backend
- You're modernising legacy jQuery, Backbone or AngularJS
- You need Node.js APIs, edge workers or full-stack JavaScript
- You need a WordPress CMS — use our WordPress services instead
- Your team exclusively runs Python or Go backends
- You need only a design or branding project
Who this service is for.
- Product teams building full-stack TypeScript applications
- Companies modernising legacy jQuery, Backbone or AngularJS codebases
- Teams building Node.js APIs and backend microservices
- Startups needing fast full-stack JavaScript MVPs
Our stack, battle-tested.
Starting from $700, depending on project scope and requirements.
What makes us different.
The people you meet in discovery stay involved through architecture, delivery and launch.
Metadata, schema, page performance and semantic markup are part of delivery, not a post-launch add-on.
Tradeoffs, integrations and scope changes are documented so your team can audit decisions later.
Repos, infra, analytics and documentation live in your accounts from the beginning.
Frequently asked questions
TypeScript by default for any non-trivial codebase. The type safety pays for itself within weeks in refactor speed and bug reduction.
Yes where it's the right choice. Bun is excellent for scripts, tests and some APIs; Node remains our default for most production systems.
Cuibit JavaScript and TypeScript projects start from $700, depending on project scope and requirements. A Node API, full-stack TypeScript product and legacy jQuery modernisation are each scoped differently — written proposal after a short discovery call.
Building both the frontend (React, Next.js) and backend (Node.js, Fastify, NestJS) in TypeScript — sharing types, models and validation logic across the entire stack for faster development and fewer bugs.
Node.js for production systems where ecosystem maturity and stability matter. Bun where raw performance, built-in testing and bundling are priorities — typically scripts, tooling and specific microservices.
Phased migration: extract components from jQuery into React, progressively replace page-by-page, and set up build tooling so old and new code coexist during the transition.
