What is Vibe Coding?

Vibe coding represents a paradigm shift in software development where you build applications by describing what you want in natural language, and AI agents handle the implementation. Lovable is one of the most popular vibe coding platforms that allows you to create production-ready applications without writing code.

In this guide, we'll build a real estate application that displays property information on an interactive map, fetching data from the syte API - all through conversational prompts with Lovable's AI.

Architecture Overview

Lovable

Frontend-only architecture that generates React applications through AI conversations

Supabase

Provides backend capabilities through Edge Functions to securely store API credentials

syte API

Delivers comprehensive real estate data while keeping credentials secure in the backend

Security First

syte API credentials must be kept secret and never exposed in frontend code. Since Lovable creates frontend-only applications, we use Supabase Edge Functions to securely manage API authentication. For more details, see our Authentication Guide.

What You'll Build

Following this guide, you'll create an application that:

Interactive map centered on Germany
Address search with geocoding
Property boundary visualization

Building information display
Floor count and area metrics
Secure API integration

The demo application shown in the video fetches real property data including built surface area (231 m²), total property area (812 m²), floor space, GRZ, GFZ, building type, and floor count - all from the syte API. View the live demo app

Prerequisites

Lovable Account - Sign up at lovable.dev
AI-powered application builder
Supabase Account - Create account at supabase.com
Backend-as-a-Service for Edge Functions
syte API Access - Contact our team for API credentials
Required for property data access
Mapbox Token (Optional) - Get from mapbox.com
For interactive map visualization

Step-by-Step Tutorial

Set up your accounts

Create accounts for Lovable, Supabase, and get syte API access

Before we start building, ensure you have all the necessary accounts set up:

• Create a Lovable account for the AI development platform
• Set up a Supabase project for backend services
• Obtain syte API credentials from our team
• (Optional) Get a Mapbox token for map visualization

Create Supabase project

Build your app foundation

Integrate syte API

The Magic Prompt Pattern

One of the most powerful features of integrating syte with Lovable is the ability to simply paste a documentation URL and let the AI understand and implement it:

Now we want to integrate the syte API to fetch property data. 
Please read the following guide carefully to understand how the API works: 
https://developer.syte.ms/guides/property-data

Implement it using supabase edge functions as the API credentials 
need to be kept secret!

Lovable will automatically:

• Fetch and analyze the documentation
• Understand the API structure
• Create appropriate Edge Functions
• Implement the integration
• Handle authentication securely

This pattern works because our guides are structured to be both human and AI-readable, containing complete examples and clear explanations.

Best Practices for Vibe Coding

Start Simple, Iterate Often
Begin with basic functionality and add features incrementally. This approach yields better results than complex initial prompts.
Be Specific About Requirements
Clearly state what you want. For example: 'Display the property outline on the map' rather than 'Show property information'.
Use the Fix Button
When errors occur, use Lovable's 'Fix' button. The AI can usually resolve issues automatically.
Explain Problems Naturally
Describe issues as you would to a human developer. Lovable understands natural language debugging.
Never Expose API Keys
Always use Supabase Edge Functions for API credentials. Never paste API keys directly into prompts that will be used in frontend code.

Common Issues & Solutions

Preview not loading?

Try refreshing the entire browser page. The Lovable preview can sometimes have loading issues.

API credentials not working?

Double-check that your syte API credentials are correctly stored in Supabase secrets and that the Edge Function has the proper permissions to access them.

Map not showing German addresses?

Make sure to specify the initial map center in your prompt. Use coordinates for Munich or another German city as the default view.

"Try to keep the prompts short, focusing on single feature improvements. Start with a simple first version and then add features one by one." - David, CTO & Co-founder of syte

Next Steps

Once you've built your first application with Lovable and syte API, consider exploring:

Add more syte API features
Integrate building potential analysis, energy efficiency data, or photovoltaic potential
Enhance the UI/UX
Improve the map interactions, add data visualizations, or create detailed property reports
Deploy to production
Use Lovable's deployment features to share your application with users
