Backend Architecture (Future)
Relevant source files
The following files were used as context for generating this wiki page:The TAF-SAF project is built using the Next.js framework, which provides an integrated, full-stack development experience. While the current project state is a minimal frontend application, the choice of Next.js defines a clear path for future backend development. The architecture will leverage server-side features built into Next.js, such as API Routes for creating endpoints and React Server Components for data fetching and rendering.
This architecture promotes a serverless-first approach, especially when deployed on platforms like Vercel, as recommended in the project's documentation. Backend logic, such as API endpoints, will be co-located with the frontend code, written in TypeScript, and benefit from the unified build process and configuration managed by Next.js.

Core Technology Stack
The foundation of the backend architecture is defined by the dependencies and configurations in package.json and tsconfig.json.
| Technology | Version | Role | Source |
|---|---|---|---|
| Next.js | 15.3.2 | The core full-stack framework for handling routing, rendering, and API endpoints. | package.json:13 |
| React | 19.0.0 | Used for building the UI, including Server Components that run on the backend. | package.json:11 |
| TypeScript | ^5 | The language for all application code, ensuring type safety. | package.json:16 |
| Node.js | ^20 | The underlying runtime environment for Next.js and the development server. | package.json:17 |
Sources: package.json:10-19
Architectural Patterns with Next.js
The future backend will be implemented using the capabilities provided by the Next.js App Router.
API Routes
For building traditional RESTful or GraphQL APIs, the project will use Next.js API Routes. These are server-side-only modules created within the src/app/api/ directory (a convention based on Next.js documentation). Each route is deployed as a serverless function, enabling automatic scaling.
The following diagram illustrates the data flow for a hypothetical API route.
This diagram represents a potential implementation based on the Next.js framework mentioned in README.md and package.json.
Server Components and Data Fetching
The project uses the Next.js App Router, where components like Home in src/app/page.tsx are React Server Components (RSCs) by default. This is a key part of the backend architecture.
- Server-Side Execution: RSCs run exclusively on the server. They can directly access backend resources (e.g., databases, file systems, internal services) without needing to be exposed through a separate API endpoint.
- Rendering: They render on the server and send HTML to the client, reducing the amount of client-side JavaScript and improving initial page load performance.
The diagram below shows the rendering lifecycle of a Server Component.
This flow is inherent to the structure of the application, as seen in src/app/page.tsx and src/app/layout.tsx.
Configuration
Backend behavior will be controlled through several key configuration files.
Package Scripts
The scripts in package.json define how the application is run, built, and maintained.
| Script | Command | Description |
|---|---|---|
dev | next dev --turbopack | Starts the development server with Turbopack for fast updates. |
build | next build | Creates a production-optimized build of the application. |
start | next start | Starts the production server after a build. |
lint | next lint | Runs ESLint to check for issues in the codebase. |
Sources: package.json:5-9
TypeScript Configuration
tsconfig.json is configured for a modern Next.js project. Key settings influencing the backend include:
| Option | Value | Implication |
|---|---|---|
target | ES2017 | Compiles TypeScript to a modern version of JavaScript compatible with Node.js environments. |
module | esnext | Uses the latest ECMAScript module syntax. |
moduleResolution | bundler | Aligns module resolution with modern bundlers used by Next.js. |
paths | {"@/*": ["./src/*"]} | Defines a path alias for cleaner imports within the project. |

Next.js Configuration
The next.config.ts file is the central place for customizing Next.js behavior. While currently empty, it will be used for future backend configurations such as:
- Setting up environment variables.
- Defining redirects, rewrites, and custom headers.
- Configuring server-side features and output modes (e.g.,
standalone).
// next.config.ts
import type { NextConfig } from "next";
const nextConfig: NextConfig = {
/* Future config options for backend behavior will be added here */
};
export default nextConfig;
Sources: next.config.ts:1-7
Deployment
The README.md recommends deployment using the Vercel Platform. This choice reinforces the serverless architecture. When deployed to Vercel:
- The Next.js application is automatically optimized.
- API Routes are deployed as individual Serverless Functions.
- Pages using Server-Side Rendering (SSR) or Server Components are handled by Edge and Serverless Functions.

Summary
The future backend architecture for TAF-SAF is defined by the Next.js framework. It will not be a monolithic, standalone server but rather an integrated set of server-side capabilities co-located with the frontend. This includes serverless API routes for client-server communication and React Server Components for efficient data fetching and server-side rendering. The entire backend will be written in TypeScript and configured for a modern, scalable deployment on serverless platforms like Vercel.
