Fullstack
Fullstack (full-stack) refers to a development approach that covers both the frontend (client) and backend (server) parts of an application. A fullstack developer understands both sides and can build a complete web application from the user interface to the database.

Benefits of the fullstack approach
The main advantage is efficiency — a single developer understands the entire project and can independently implement functionality from the frontend through to the backend. This means faster development, less team communication and lower costs for smaller projects. A fullstack developer sees the bigger picture and can make optimal architectural decisions.

Modern fullstack technologies
Next.js is a textbook fullstack framework — in a single project you have a React frontend, API routes for the backend and server components. Other popular fullstack frameworks are Nuxt.js (Vue), SvelteKit (Svelte), Remix and Laravel (PHP). At Appitect we build fullstack applications on Next.js with TypeScript, which lets us share types between the frontend and backend.

Fullstack vs. specialisation
On larger projects it makes sense to have specialists — a dedicated frontend and a dedicated backend developer. Each can dive deeper into their area. For small and mid-sized projects the fullstack approach is ideal — there is no need to coordinate two teams. At Appitect we combine both approaches depending on project scope.

How to become a fullstack developer
A fullstack developer needs to know HTML, CSS, JavaScript (or TypeScript), at least one framework (React, Vue), the basics of the backend (Node.js, databases), version control (Git) and deployment. They do not have to be an expert in everything, but they must understand the principles and be able to tie it all together. A T-shaped profile — broad knowledge with deep expertise in 1–2 areas.

Practical example
At Appitect we typically build company websites as fullstack projects in Next.js. A single developer creates the entire site: React components for the frontend, API routes for the contact form and newsletter, a database connection for lead tracking and deployment to Vercel. Everything in one repository, in one language (TypeScript).
