API Routes (Future)
Relevant source files
The following files were used as context for generating this wiki page:
This document outlines the architecture and conventions for creating future API endpoints within the TAF-SAF project. The project is built using Next.js and the App Router, which provides a file-based routing system for both UI pages and server-side API routes. While no API routes currently exist, the project's structure and dependencies establish a clear path for their implementation as "Route Handlers".
The foundation for API development is provided by the Next.js framework, version 15.3.2, and a TypeScript environment. This setup allows for the creation of type-safe, server-side logic that can handle HTTP requests and return data, typically in JSON format. All future API routes will be co-located with the front-end components within the src/app/ directory.

API Architecture Foundation
The project's architecture is based on the Next.js App Router. This is evident from the directory structure, which includes src/app/page.tsx and src/app/layout.tsx. In this paradigm, API endpoints are defined by creating special files named route.ts (or .js) within subdirectories of src/app/.
Sources: README.md:15, src/app/page.tsx, src/app/layout.tsx
File-based Routing
API routes will be mapped from URL paths to files on the filesystem. A folder named api should be created inside src/app to house all endpoints. Each subsequent sub-folder path will correspond to a URL segment.
The following diagram illustrates how a future API endpoint at /api/users would be structured within the project.
This diagram shows that a request to /api/users would be handled by the logic inside src/app/api/users/route.ts.

Creating Route Handlers
A Route Handler is a TypeScript file (route.ts) that exports one or more functions corresponding to HTTP methods (e.g., GET, POST, PUT, DELETE). When an HTTP request is made to the URL matching the file's path, Next.js invokes the corresponding exported function.
Example Route Handler
A hypothetical route.ts file for a GET request would look like this. The project's Next.js dependency provides the necessary NextRequest and NextResponse types for handling requests and responses.
// Hypothetical file: src/app/api/example/route.ts
import { NextResponse } from 'next/server';
export async function GET(request: Request) {
// Future API logic would go here
const data = { message: 'This is a sample API response.' };
return NextResponse.json(data);
}
This structure is the standard convention for the version of Next.js used in this project.

Request-Response Flow
The sequence diagram below illustrates the flow for a client requesting data from a future API endpoint.
This diagram shows the server-side execution of the GET function within the Route Handler to produce a JSON response.

Configuration and Tooling
The project is pre-configured with TypeScript and other tools that will support API development.
TypeScript Configuration
The tsconfig.json file defines the rules for the TypeScript compiler. It is set up to handle modern JavaScript features and Next.js-specific syntax. API routes must be written in TypeScript to align with the project's standards.
| Option | Value | Description |
|---|---|---|
target | ES2017 | Compiles TypeScript to the ES2017 JavaScript standard. |
module | esnext | Uses the latest ES module syntax. |
strict | true | Enforces strict type-checking rules for higher code quality. |
paths | {"@/*": ["./src/*"]} | Allows for absolute imports from the src directory (e.g., import MyUtil from '@/utils/my-util'). |
plugins | [{"name": "next"}] | Integrates TypeScript with the Next.js compiler and type system. |
Sources: tsconfig.json:1-26
Next.js Configuration
The next.config.ts file is currently empty but serves as the central point for customizing the Next.js build and runtime behavior. Future API-related configurations, such as environment variables, custom headers, or redirects, would be added here.
// File: next.config.ts
import type { NextConfig } from "next";
const nextConfig: NextConfig = {
/* config options here */
};
export default nextConfig;
Sources: next.config.ts:1-6
Development Workflow
The development process for API routes follows the same workflow as for UI pages, as defined in package.json.
| Script | Command | Description |
|---|---|---|
dev | next dev --turbopack | Starts the development server with Turbopack for fast refresh. API changes are reflected instantly. |
build | next build | Creates a production-optimized build of the application, including API routes. |
start | next start | Runs the production server after a build. |
lint | next lint | Lints the codebase to check for errors and style issues. |
Sources: package.json:4-8
The development lifecycle is streamlined for rapid iteration.
This flow is enabled by the npm run dev script.
Sources: README.md:9-13, package.json:5
Conclusion
The TAF-SAF project is well-equipped for the future addition of API routes. By leveraging the Next.js App Router, developers can create robust, server-side Route Handlers using TypeScript. The existing project configuration provides a solid foundation for a streamlined development workflow, from initial coding with instant feedback to building and deploying a production-ready application. The convention is to place all API logic within route.ts files inside the src/app/api/ directory.
