Modern JavaScript & TypeScript Development
JavaScript runs more of the internet than any other language. We write modern JavaScript and TypeScript for front-end, back-end, edge runtimes, and build tooling — with type safety, tests, and performance budgets baked in from day one.
Our stack preferences: TypeScript over plain JS for anything non-trivial, React or Vue for UIs, Next.js or Nuxt for full-stack, Node.js or Bun for services, Playwright for end-to-end, Vitest or Jest for units. We'll adapt to whatever your team already runs.
JavaScript Work We Do
- Full-stack Next.js and Nuxt applications
- Node.js and Bun API services with TypeScript
- React component libraries and design systems
- Vue, Svelte, and Solid apps when the project fits
- Migration from legacy jQuery or AngularJS to modern frameworks
- Serverless and edge functions (Vercel, Cloudflare Workers, AWS Lambda)
- CLI tools, scripts, and automation in Node.js
- Electron and Tauri desktop apps when native wrap is needed
What We Bring Beyond Syntax
- Type-safe end-to-end — shared types across client and server
- Test coverage that protects refactors, not just coverage badges
- Performance budgets enforced in CI — bundle size, LCP, TTFB
- Monorepo and package-publishing patterns that scale
- Migration playbooks for moving away from deprecated frameworks
JavaScript stack feeling heavy? We can audit, simplify, or rebuild it.

What is JavaScript Development?
Balianti builds modern JavaScript and TypeScript applications — React, Next.js, Node.js, Vue, and serverless — with type-safe code, strong test coverage, and production patterns.
How does Balianti approach javascript development?
We start with a 30-minute discovery call, scope a fixed-price proposal within 48 hours, prototype key flows, build in weekly sprints with Friday demos, launch with zero downtime, and offer an optional support retainer. Same process for every javascript development engagement.
How long does a typical javascript development project take?
Scoped work ships in 4-12 weeks depending on scale. Discovery and proposal are free and delivered in 48 hours. You will see working software every week.
What technologies does Balianti use for javascript development?
Our core stack includes Node.js, React, Next.js, TypeScript, PostgreSQL, Python, .NET, Java, Flutter, React Native, AWS, Azure, and Google Cloud. We will recommend the right stack for your specific requirements.
