That is incredibly powerful.\n\nBut there is a problem:\n\n**Generating code is easy. Building a scalable application is not.**\n\nFor serious projects, I don't think the best approach is:\n\n“Give AI a prompt and let it build everything.”\n\nA better approach is to give AI **structure, rules, and context** before asking it to generate code.\n\nBefore writing code, define what the application actually needs.\n\nThink about:\n\nThis gives the AI a clear target.\n\nNext, define the basic architecture:\n\n**Frontend → API → Backend → Database → External Services**\n\nDecide important things such as:\n\nDon't start generating hundreds of files yet.\n\nFor most applications, the database is one of the most important foundations.\n\nDefine your:\n\nI also like generating an **ERD using Mermaid** before creating the actual database.\n\nThis makes the relationships easy to review before implementation.\n\nOnce the schema is approved, create the database and migrations.\n\nFor PostgreSQL, don't blindly add indexes everywhere.\n\nThink about the queries your application will actually run.\n\nFor example:\n\nUse tools such as `EXPLAIN ANALYZE`\n\nto understand real query performance.\n\n**The best index depends on the query.**\n\nNow AI can generate the backend based on the approved architecture and schema.\n\nA simple structure might be:\n\n**Controller → Service → Repository → Database**\n\nThen add:\n\nThe important part is that AI should follow the architecture rather than inventing a new structure for every feature.\n\nBefore connecting the frontend, define the API clearly.\n\nFor each endpoint, specify:\n\n**Method + URL + Request + Response + Errors + Authentication**\n\nThis prevents the frontend and backend from slowly becoming inconsistent.\n\nNow connect the frontend to the API.\n\nA clean flow is:\n\n**UI → State → API Client → Backend**\n\nKeep API calls organized instead of scattering raw requests throughout components.\n\nAlso handle:\n\nAI can generate tests too, but generated tests aren't enough.\n\nActually run them.\n\nTest:\n\nA test that nobody runs doesn't protect your application.\n\nBefore production, review:\n\nFor performance, **measure first and optimize second**.\n\nFind the actual bottleneck instead of optimizing everything because AI suggested it.\n\nI don't think the future is about developers disappearing.\n\nI think it's about developers becoming better at **directing AI**.\n\nInstead of:\n\n“Build my entire application.”\n\nTry:\n\n“Here is my architecture, database schema, API contract, coding standards, and constraints. Implement this feature, explain the changes, and verify it with tests.”\n\nThat's the difference between **AI-generated code** and **AI-assisted engineering**.\n\nAI can write a lot of code.\n\nBut **you still need to design the system.**", "url": "https://wpnews.pro/news/vibe-coding-in-the-new-era-how-to-build-real-applications-with-ai", "canonical_source": "https://dev.to/darun_karasabir_b79602fd/vibe-coding-in-the-new-era-how-to-build-real-applications-with-ai-1dn", "published_at": "2026-08-24 05:04:10+00:00", "updated_at": "2026-08-24 05:43:03.808920+00:00", "lang": "en", "topics": ["developer-tools", "artificial-intelligence", "ai-products"], "entities": ["PostgreSQL", "Mermaid"], "alternates": {"html": "https://wpnews.pro/news/vibe-coding-in-the-new-era-how-to-build-real-applications-with-ai", "markdown": "https://wpnews.pro/news/vibe-coding-in-the-new-era-how-to-build-real-applications-with-ai.md", "text": "https://wpnews.pro/news/vibe-coding-in-the-new-era-how-to-build-real-applications-with-ai.txt", "jsonld": "https://wpnews.pro/news/vibe-coding-in-the-new-era-how-to-build-real-applications-with-ai.jsonld"}}
