Next.js Development
Next.js Development Services
Fast, SEO-friendly, scalable web applications built on Next.js and React, for startups, enterprises, and growing businesses in Indonesia and beyond.
This website is itself a Next.js 15 App Router application, as are Javapixa’s client builds and the Inpixa platform.
Rendering is decided per route, not once for the whole site.
The fit
When Next.js is the right call
Businesses whose site has outgrown a template or WordPress build: teams needing real application behaviour, strong Core Web Vitals, integrations with existing APIs, or room to grow a marketing site into a product.
- A template site that cannot do what the business now needs
- Slow loading that costs rankings and conversions
- A marketing site and an application maintained as two separate things
- Plugin stacks that break on every update
- No clean way to connect the site to internal systems
If the site is mainly content and your team edits it daily, WordPress may serve you better, Javapixa builds that too, and will say so.
Comparison
Next.js build vs a template or WordPress site
Where the difference actually shows up, including the row where WordPress wins.
| Aspect | Template / WordPress | Next.js by Javapixa |
|---|---|---|
| Page speed | Depends on the theme and on how many plugins are active | Server-rendered HTML, split bundles, images and fonts optimised per route |
| SEO control | Delegated to a plugin whose output you do not control | Metadata, canonical URLs, hreflang, schema and sitemap written in the codebase |
| Custom features | Limited to what a plugin already does, or bolted on afterwards | Anything expressible in code, including your own API routes |
| Updates | Plugin and theme updates can break the site without warning | Versioned dependencies, and TypeScript catches breakage at build time |
| Daily content editing | Strong out of the box — non-technical staff edit pages directly | Needs a headless CMS wired in, which we do when the team edits often |
| Growing into an application | Usually means a rebuild on a different stack | The marketing site and the application live in one codebase |
Scope
What the build includes
App Router architecture
Server Components by default, Client Components only where interactivity needs them, which keeps the JavaScript bundle small.
Core Web Vitals
Image and font optimisation, route-level code splitting, and rendering chosen per route rather than one strategy for the whole site.
SEO built in
Metadata, canonical URLs, hreflang, schema.org and sitemaps handled in the framework rather than bolted on by plugin.
Real integrations
Connects to your existing REST or GraphQL APIs, PostgreSQL or MySQL databases, and headless CMSs.
Migration from WordPress
Content moved, templates rebuilt as components, and URLs kept stable or redirected properly so existing rankings survive.
TypeScript throughout
Strict mode across the codebase, so breaking changes surface at build time instead of in production.
Method
Four ways to render, chosen per page
Most site builders apply one rendering strategy everywhere. Next.js lets each route pick the one that suits it, which is where most of the speed comes from.
Static generation
Pages that look the same for every visitor: services, case studies, landing pages.
Rendered once at build time and served from the CDN, so the first byte does not wait for a server.
Incremental revalidation
Content that changes on its own schedule: blog posts, project listings, catalogues.
Pages rebuild in the background on a set interval, with no redeploy and no stale cache to clear by hand.
Server rendering
Anything that depends on the request: signed-in dashboards, personalised or language-aware pages.
Rendered per request on the server, so the browser receives finished HTML instead of an empty shell.
Client components
Interactive islands only: forms, carousels, filters, live widgets.
Shipped as JavaScript to the browser. Everything outside those islands stays on the server and costs the visitor nothing.
Migration
Moving an existing site to Next.js
The risk in a migration is not the rebuild, it is losing the search visibility the old site already earned. The sequence below exists to prevent that.
Audit and URL inventory
Every published URL, template, form, and third-party integration is listed before anything is touched, so nothing is discovered missing after launch.
Templates become components
Each theme template is rebuilt as a React component. The design is kept as-is or redesigned deliberately, not lost in translation.
Content moves
Posts, pages, and media move into a headless CMS or into the codebase, depending on how often your team actually edits them.
Redirects, crawl, launch
URLs stay identical where they can and get proper 301s where they cannot. The new site is crawled and checked against the old inventory before DNS is switched.
What is protected during the move
- Existing URLs and the rankings attached to them
- Published content and media
- Analytics and tracking setup
- Forms and third-party integrations
What we build with it
Technology
The same stack this site runs on, chosen because it is maintained in production rather than because it is new.
How we work
How a Next.js build runs
Discovery and architecture
Routes, rendering strategy per route, data sources, and integrations are agreed before any code is written.
Design system and components
Design tokens and a component library first, so pages are assembled from reviewed pieces instead of one-off markup.
Build and integrate
App Router build in TypeScript strict mode, APIs and CMS connected, with a preview deployment on every change you can click through.
Launch and handover
Deployment pipeline set up, source code and documented architecture handed over, and the team walked through it.
Handover
You own what we build
The source code is yours at handover, in your own repository, with the architecture documented and the deployment pipeline in your own accounts. Another developer can pick it up without going through Javapixa first — a Next.js codebase is a widely understood standard, not a proprietary system.
What is delivered
Proof
The demo is the page you are reading
Rather than ask you to trust a claim about performance, here is what this site does, all of it inspectable from your own browser.
Next.js 15, App Router
This site is a Next.js 15 App Router application, with Server Components as the default and client code only where it is needed.
TypeScript in strict mode
The whole codebase, including the content and metadata layers, is typed and fails the build rather than production.
SEO written in code
Per-page canonical URLs, hreflang alternates, JSON-LD, and a generated sitemap — no SEO plugin anywhere.
Readable by AI agents
The same pages are served as markdown to agents that ask for it, alongside /llms.txt and a full reference at /llms-full.txt.
Proof
Work we have delivered
Real projects, with the problem and the approach written up in full.
Timeline
How long does it take?
A Next.js marketing site typically runs 3–6 weeks; a full web application with authentication and a database runs 8–12 weeks or more. A migration from an existing site depends on how much content and how many integrations move with it.
These are typical ranges, not commitments. The actual schedule is agreed during discovery, once scope and integrations are clear.
Pricing
How much does it cost?
Javapixa quotes per project, not per hour. The client selects a budget band during the quote request and Javapixa scopes the work to fit it.
Rp 5,000,000 – 15,000,000
Landing pages, single-page event sites, small company profiles, website templates, brand identity packages.
Rp 15,000,000 – 25,000,000
Multi-page corporate profile sites with CMS, catalogue or portfolio sites, UI/UX design engagements.
Rp 25,000,000 – 50,000,000
E-commerce builds, government and institutional portals, custom WordPress themes, larger marketing sites with integrations.
Rp 50,000,000 – 100,000,000
Full-stack web applications with authentication, roles, and databases; mobile apps; multi-month builds.
Rp 100,000,000+
Enterprise systems, multi-app platforms, long-running engagements, and projects needing dedicated infrastructure.
Custom
Anything that does not fit a band, the client describes the budget in their own words.
Quotes are free. Javapixa does not publish fixed package prices because scope drives cost; the budget band plus the project description is enough to produce an accurate quote.
