Build Next.js API for Your iOS App (Complete Guide)
Build custom Next.js API server serving data to SwiftUI iOS applications while hosting landing page on same domain. Learn creating API routes, implementing file-based caching, structuring JSON responses, and integrating endpoints into iOS apps. Covers deployment to Vercel, public API patterns, and combining frontend marketing site with backend API services in single Next.js project.
Why Next.js for iOS Backend:
Next.js provides unified solution hosting both landing page and API routes on single domain simplifying deployment and domain management. The framework handles frontend React components and backend API routes simultaneously eliminating need for separate server infrastructure. This architecture enables indie developers shipping complete product stack including marketing site and mobile backend using single codebase and deployment pipeline.
Project Overview:
The implementation replaces external APIs with custom Next.js backend serving quotes data to iOS quote widget application. Base URL points to Vercel-hosted Next.js application providing public API without authentication requirements. Future plans include landing page enhancement and potential Supabase authentication integration once traffic increases warranting API key protection.
API Structure Changes:
Modified endpoints include quote of the day, all quotes, and category filtering replacing previous external dependencies. The code.json file contains all data served to iOS application including quote text, authors, and categories. Base URL updated pointing to personal Vercel deployment enabling complete control over API responses and data structure.
Database Schema Updates:
Added favorite, author, and categories fields to SQL tables supporting new application features. The schema modifications enable user favorites, author attribution, and category filtering improving content organization. These changes reflect evolution from simple quote display to feature-rich application with user preferences and content categorization.
Next.js API Route Implementation:
File system routing uses `route.ts` files defining GET request handlers. The implementation imports Node.js fs module for file reading, Next.js response utilities for HTTP responses, and path module for file path resolution. Memory caching stores loaded data reducing file system reads improving response times for frequently accessed data.
Perfect For:
iOS developers wanting custom backend control. Indie developers building full product stack solo. Teams consolidating frontend and API infrastructure. Builders wanting public API without authentication overhead. Developers migrating from external APIs to self-hosted. Anyone seeking unified landing page and API deployment.
Future Video Plans:
Upcoming demo showing complete iOS application using custom API. Tutorial covering star to favorite functionality implementation. Swipe to delete and swipe gestures explained. Complete code walkthrough once feature set stabilizes.
Critical Files:
`route.ts` in API directory defines endpoint logic and caching. `code.json` in public directory contains all quote data. `APICode.swift` defines endpoint paths and request methods. `APICodeService.swift` handles base URL and JSON parsing.
