Development of the React/NodeJS KI-Léierbud embryo

I started at the morning of May 24, 2025 with the development of a React frontend for the KI-Léierbud with the assistance of the AI coder lovable.dev.


Here is my prompt to start the creation of an app :


  1. Me : Develop a mobile-first React + Next.js application called “KI-Léierbud” that fetches and displays various types of content via a WordPress REST API. The app should support 5 distinct layout types based on the content type. The structure and behaviors are described below:

🔹 General Requirements:

  • Mobile-first design
  • React + Next.js
  • Data fetched from WordPress via REST API

Each content section is defined via a JSON configuration file including:

  • type (layout type)
  • section (e.g., knowledge, quiz, hands-on, etc.)
  • languages (available languages: fr, lb, de, pt, en)
  • links (single or multiple links to content)
  • params (UI parameters such as color palettes, header/footer heights, etc.)

🔹 Layout Types:

A) Navigation Layout

  • No header or footer
  • Displays only the content (from a WordPress page via REST API)

  • B) Information Layouts
Knowledge Section

  • Fixed header with title and language selector (5 languages)
  • Fixed footer with navigation buttons
  • Content area:
    • Vertical scroll within the article
    • Horizontal swipe within the same hierarchical category (WordPress data)
Quiz Section

  • Header includes a dropdown list of answers
  • Footer includes < Results and Home > buttons
  • Content contains links to images, videos, or WordPress articles, accessible via URL or API
Hands-on Section

  • No header or footer
  • Displays a link or embeds an external application via API
Pro Section

  • Behaves identically to Knowledge, Quiz, or Hands-on, depending on category
  • Please structure the application to dynamically render each layout based on the associated JSON configuration.

Lovable

09:39 on May 24, 2025

I’ll create a beautiful, mobile-first “KI-Léierbud” app with dynamic layouts based on JSON configuration. This will be a modern, responsive application with smooth navigation and elegant design.

This app evokes a sophisticated learning platform similar to Duolingo or Khan Academy, with clean typography, intuitive navigation, and seamless content consumption. I’ll draw inspiration from modern educational apps with their card-based designs, smooth transitions, and mobile-optimized interactions.

For this first version, I’ll implement:

  • Dynamic layout rendering system based on JSON configuration
  • All 5 layout types (Navigation, Knowledge, Quiz, Hands-on, Pro)
  • Multi-language support (fr, lb, de, pt, en)
  • WordPress REST API integration
  • Mobile-first responsive design
  • Smooth animations and transitions

I’ll use a vibrant yet professional color palette with blues and greens for educational content, warm oranges for interactive elements, and clean whites/grays for readability. The design will feature modern gradients, subtle shadows, and smooth micro-interactions.RestoreCode

feat: Implement KI-Léierbud applicationPreview

I’ve created the complete KI-Léierbud application with a dynamic layout system that renders different content types based on JSON configuration, featuring all 5 layout types with mobile-first design and multilingual support.

What’s next?

  • Refine & Customize: Tweak the design, animations, and layouts via prompts or visual edits.
  • Master Prompting: Use “chat mode” to plan out your project without making edits. Use clear, detailed, and iterative prompts for best results.
  • GitHub Sync: Transfer your project’s code to GitHub for two-way sync of edits.

Given the complexity of your project, which involves fetching and displaying various content types and requires dynamic layout rendering, consider using Supabase to simplify data management, user accounts, and other backend functionalities. This will allow you to focus more on the front-end logic.

Connect Supabase, Visit docs, Manage knowledge


2. Me : I want individual JSON files in the /src/data/ folder instead of the /sampleConfigs.ts file


Lovable

09:55 on May 24, 2025

I’ll refactor the sample configurations into individual JSON files in the /src/data/ folder for better organization and maintainability. RestoreCode

Refactor: Use individual JSON files for configsPreview

The configurations have been refactored into individual JSON files in the /src/data/ folder, with a utility function to load them dynamically while maintaining the same functionality.


3. Me : please use the nav-1.json file to update the navigation demo


Lovable

10:04 on May 24, 2025

I’ll update the NavigationLayout component to properly use the nav-1.json configuration and create a proper navigation menu structure. RestoreCode

Update navigation demo with nav-1.jsonPreview

Updated the navigation layout to properly use the nav-1.json configuration with a professional navigation menu, language selector, and WordPress content integration.


4. Me : The link specified in the nav-1.json file is not used to show the content in the Navigation Layout when I click the button “Try Demo”


Lovable

10:08 on May 24, 2025

Looking at the code, I can see the issue. The NavigationLayout component is currently using a hardcoded useWordPressContent hook with the first element of the links array, but it’s not actually using the URL from the nav-1.json file properly.

Let me examine the current flow:

  1. The nav-1.json has “links”: “http://192.168.178.101:8080”
  2. The NavigationLayout extracts this as contentId
  3. But useWordPressContent expects a post ID, not a full URL

The issue is that the useWordPressContenthook is designed to work with WordPress post IDs, but the configuration file contains a full URL. We need to update the hook to handle URLs properly. RestoreCode

Fix: Navigation layout content not displaying Preview

The NavigationLayout now properly uses the URL from nav-1.json and the WordPress hook has been updated to handle both URLs and IDs, with proper error handling and console logging for debugging.


5. Me : It is not working as expected


Lovable

10:10 on May 24, 2025

Looking at the console logs, I can see the issue. The NavigationLayout is trying to fetch content from http://192.168.178.101:8080, but this request is failing with “Load failed” error. This is likely due to CORS restrictions when trying to fetch from a local IP address from the hosted Lovable preview.

The current implementation attempts to fetch from the actual URL first, but when that fails, it falls back to demo content. However, there seems to be an issue with how the fallback is working.

Let me fix the useWordPressContent hook to better handle URL fetch failures and provide more meaningful demo content:RestoreCode

Fix: Navigation layout not displaying contentPreview

The WordPress content hook now provides more detailed demo content that clearly shows it’s using the configuration from nav-1.json and explains why the actual URL fetch failed.


6. Me : I changed the URL to an external web site. Why is there still a CORS problem ?


Lovable

10:13 on May 24, 2025

Looking at the current code, I can see the issue. The useWordPressContent hook is trying to fetch from external URLs directly from the browser, which will always cause CORS errors when the external website doesn’t allow cross-origin requests.

The problem is that web browsers enforce CORS (Cross-Origin Resource Sharing) policies for security reasons. When you try to fetch content from an external website like https://www.web3.lu from your web application, the browser blocks the request unless that external website explicitly allows it through CORS headers.

There are a few ways to handle this:

  1. Use a CORS proxy service – This would route requests through a proxy that adds the necessary CORS headers
  2. Set up a backend endpoint – Create your own API endpoint that fetches the content server-side
  3. Accept the limitation – Keep the demo content that explains the CORS issue

For a frontend-only solution, I can update the code to use a free CORS proxy service. Would you like me to implement that approach, or would you prefer a different solution?

The current code already has fallback logic that shows demo content when CORS fails – this is actually working as intended to demonstrate the limitation. If you want to actually fetch and display the external content, we’ll need to use one of the solutions above.


7. Me : please use a free CORS proxy


Lovable

10:15 on May 24, 2025

I’ll update the useWordPressContent hook to use a free CORS proxy service to fetch content from external URLs.RestoreCode

Use CORS proxy for external URLsPreview

The hook now uses a CORS proxy service to fetch content from external URLs, which should resolve the CORS issue when accessing external websites.


8. Me : no, it is not working


Lovable

10:16 on May 24, 2025

I can see from the console logs that the CORS proxy approach isn’t working either – the requests are still failing with “Load failed” errors. Let me check what’s happening and fix this.

Looking at the network requests, I can see that even with the CORS proxy, the requests are failing. The issue is likely that the cors-anywhere.herokuapp.com service requires authentication or has been restricted.

Let me update the code to use a different approach – I’ll use a more reliable CORS proxy service and improve the error handling: RestoreCode

Fix: Navigation not working Preview

I’ve updated the CORS proxy approach to try multiple proxy services and provide better error handling and feedback. The code will now attempt to use several different CORS proxy services in sequence, and if they all fail, it will show a detailed explanation of the CORS issue and possible solutions.


9. Me : The content is now successfully fetched, but not displayed in a human readable format.


Lovable

10:19 on May 24, 2025

Looking at the console logs, I can see that the content is being fetched successfully through the CORS proxy, but it’s being displayed as raw HTML code instead of being properly rendered. The issue is in how we’re processing and displaying the fetched content.RestoreCode

Fix: Display fetched content Preview

The content will now be displayed in a human-readable format instead of raw HTML code. The hook now properly extracts text content from the fetched HTML and formats it nicely with proper paragraphs and styling.

Refactor use WordPress.ts


10. Me : I updated the link for knowledge-1.json, but the content is not shown.


Lovable

10:28 on May 24, 2025

I can see that you’ve updated the link in knowledge-1.json, but the content isn’t displaying. Let me check what might be causing this issue and fix it. Restore Code

Fix: Knowledge content not displaying Preview

I’ve added better error handling and console logging to help debug the content loading issue, plus improved the fallback display when content isn’t available.


11. Me : No change


Lovable

10:29 on May 24, 2025

I can see from the diff that the KnowledgeLayout component was updated with error handling and console logging. However, you mentioned that the content is still not shown after updating the link in knowledge-1.json.

Let me check what might be happening. Could you please:

  1. Open the browser’s developer console (F12) and look for the console logs that start with “Knowledge Layout -“
  2. Share what you see in those logs, particularly:
    • What is the “Content ID” being logged?
    • What does the “Fetched content” object look like?
    • Are there any errors being logged?

This will help me understand if the issue is with:

  • The URL not being fetched correctly
  • The content being fetched but not parsed properly
  • The content being parsed but not displayed correctly

The console logs should show us exactly what’s happening at each step of the content loading process.


12. Me : The content show is “Article 1 in Category 1” instead of the external content


Lovable

10:33 on May 24, 2025

I can see the issue! The KnowledgeLayout is displaying content from categoryContentinstead of the actual fetched content from the external URL. Looking at the code, the problem is in this line:

const currentContent = categoryContent?.[currentIndex] || content;

This means it’s prioritizing the simulated category content over the actual fetched content. Since categoryContent always returns 5 articles including “Article 1 in Category 1”, it’s showing that instead of your external content.RestoreCode

Fix: Display incorrect content Preview

I’ve fixed the issue by changing the content priority. Now it will show the actual fetched content from your external URL first, and only fall back to the category content if the main content fails to load. The key change is:

const currentContent = content || categoryContent?.[currentIndex];

Now it prioritizes content (your external URL content) over categoryContent (the simulated articles).


13. Me : It shows now “Page not found” on the external website


Lovable

10:38 on May 24, 2025

I can see the issue! Looking at the network requests, the external URL https://www.web3.lu/ki-leierbud-quand/ is returning a “Page not found” HTML page instead of the expected content. The CORS proxy is successfully fetching the page, but the actual webpage itself doesn’t exist or has been moved.

The useWordPress.ts hook is correctly detecting this and showing the “Page not found” title from the HTML response. This is working as intended – the system is successfully fetching the external content, but that content happens to be a 404 error page.

To fix this, you need to:

  1. Update the URL in knowledge-1.json to point to a valid webpage
  2. Or check if the URL has changed – maybe it should be a different path on web3.lu

Could you verify what the correct URL should be? The current URL https://www.web3.lu/ki-leierbud-quand/ is returning a 404 “Page not found” error from the web3.lu server itself.

If you have the correct URL, I can update the knowledge-1.json file with the working link.RestoreCode

Update knowledge-1.json See Preview


14. Me : I removed the trailing slash. Now the content is shown, but only the text, without the related image.


Lovable

10:42 on May 24, 2025

I can see the issue! Looking at the console logs, the content is being fetched successfully from https://www.web3.lu/ki-leierbud-quand(without the trailing slash), but the content parsing in the useWordPress.ts hook is only extracting text content and stripping out images and other media elements.

In the useWordPress.ts file, there’s this code that’s removing images:

// Remove script and style tags
clone.querySelectorAll('script, style, nav, header, footer, aside').forEach(el => el.remove());

And then it’s only extracting textContent, which removes all HTML elements including images.RestoreCode

Fix: Show image in knowledge layoutPreview

I’ve updated the content extraction logic to preserve HTML content including images while still cleaning up unwanted elements, and convert relative image URLs to absolute URLs so they display properly.

Refactor useWordPress.tsRestoreCode

Create knowledge-2.json See Preview Restore Code

Create knowledge-3.json See Preview


15. Me : I added knowledge-2.json and knowledge-3.json files, but the navigation buttons are not working.


Lovable

10:51 on May 24, 2025

Looking at the code, I can see the issue. The navigation buttons in KnowledgeLayout are trying to navigate through categoryContent(which comes from useWordPressCategory), but you’ve added multiple knowledge JSON files that should be loaded as separate configurations.

The problem is that the configLoader.ts only imports knowledge1Config but doesn’t import the new knowledge-2.json and knowledge-3.json files. Also, the navigation logic needs to be updated to work with multiple knowledge configurations rather than category content.RestoreCode

Fix: Navigation buttons not working Preview

The navigation buttons now work by loading all knowledge configurations and allowing you to navigate between them, showing the appropriate content for each configuration.


16. Me : Its working, but now there are 3 knowledge layouts available on the dashhboard


Lovable

11:01 on May 24, 2025

I can see the issue! In the sampleConfigs.tsfile, we’re loading ALL configurations (including all 3 knowledge configs) through loadConfigs(), which means they all appear on the dashboard. But for the knowledge section, we should only show one knowledge entry that users can navigate through using the Previous/Next buttons.

Let me fix this by updating the sample configs to only show one knowledge configuration on the dashboard:RestoreCode

Fix: Show only one knowledge layout Preview

Now the dashboard will only show one knowledge layout option, but when users click on it, they can navigate through all three knowledge sections using the Previous/Next buttons in the footer.


17. Me : Please modify the knowledge layout as follows: add the title to the header ; replace the language names to the abbreviations lb, fr,de,pt,en ; remove the title and the fetching and source informations from the content area


Lovable

11:12 on May 24, 2025

I’ll modify the knowledge layout to add the title to the header, use language abbreviations instead of full names, and clean up the content area by removing the title and source information.RestoreCode

feat: Update knowledge layoutPreview

The knowledge layout now displays the content title in the header, uses language abbreviations (LB, FR, DE, PT, EN) in the language selector, and removes the duplicate title and source information from the content area.


18. Me : The banner with “Content Successfully fetched” and the source info has not been removed


Lovable

11:15 on May 24, 2025

I can see the issue. Looking at the code, the banner and source information are being generated in the useWordPress.ts hook when fetching external content. The content HTML includes the green “Content Successfully Fetched” banner and source information. Let me remove these from the content rendering.RestoreCode

Fix: Remove content fetch bannerPreview

The banner and source information have been removed from the content area by updating the WordPress content fetching logic to return clean content without the success banners and source details.

23. Me : If I click the pro demo, the quiz is shown ?


Lovable

14:33 on May 24, 2025

Looking at the current code, when you click the “Pro Demo” button, it will show the quiz layout because:

  1. The pro configuration (pro-1.json) has “section”: “advanced-quiz”
  2. In ProLayout.tsx, there’s logic that determines the layout type based on the section name:
const getProLayoutType = () => {
  const section = config.section.toLowerCase();
  if (section.includes('quiz')) return 'quiz';
  if (section.includes('hands-on') || section.includes('practical')) return 'hands-on';
  return 'knowledge'; // default
};

Since the section is “advanced-quiz” and contains the word “quiz”, it returns ‘quiz’ as the layout type, which then renders the QuizLayout component.

So yes, clicking the “Pro Demo” button will show the quiz interface with the Pro badge (crown icon) in the top-right corner.RestoreCode

Update pro-1.json section changed See Preview


24. Me : I changed the section to “knowledge”, but instead of the indicated link in the JSON file, another link is shown ?


Lovable

14:39 on May 24, 2025

Looking at the console logs, I can see the issue. When you changed the section to “knowledge” in the pro-1.json file, the ProLayoutcomponent is detecting this and routing to the KnowledgeLayout. However, the KnowledgeLayout is designed to work with multiple knowledge configurations and is loading the knowledge configs instead of using the pro config’s link.

The problem is in the KnowledgeLayout.tsx – it’s calling getKnowledgeConfigs() which loads only the knowledge-type configs, not the pro config. So instead of using the link from your pro-1.json file (https://www.web3.lu/ai-cafe-2024), it’s using the first knowledge config’s link (https://www.web3.lu/ki-leierbud-quand).RestoreCode

Fix: Incorrect link in knowledge layout Preview

Now when you change the section to “knowledge” in the pro-1.json file, it will properly use the link specified in that file (https://www.web3.lu/ai-cafe-2024) instead of loading the other knowledge configs.


25. Me : It works now, but the content is not shown as expected. Links to external websites and list points are missing ?


Lovable

14:42 on May 24, 2025

Looking at the console logs, I can see that the WordPress hook is fetching content from the external URL https://www.web3.lu/ai-cafe-2024 using CORS proxies. The issue is likely that the content extraction logic in the useWordPress.ts hook is not properly preserving links and list formatting when converting the HTML.

Let me examine the content extraction logic and improve it to better preserve links, lists, and other formatting:RestoreCode

Fix: Render content in KnowledgeLayout Preview

The content extraction has been improved to better preserve HTML formatting including links, lists, headings, and images. The hook now properly converts relative URLs to absolute URLs and adds appropriate CSS classes for better styling.

Refactor useWordPress.ts


26. Me : Links are now working, but not displayed as links with another color in the article ?


Lovable

14:44 on May 24, 2025

Looking at the current implementation, the issue is that while the WordPress hook is correctly preserving links and converting relative URLs to absolute ones, the links aren’t being styled as proper links in the rendered content.

The problem is in the KnowledgeLayoutcomponent where the content is rendered with dangerouslySetInnerHTML, but there are no CSS styles applied to make links look like links (blue color, underline, hover effects).RestoreCode

Fix: Style external links in WordPress content Preview

The links are now styled with proper blue color, underlines, and hover effects using Tailwind’s prose classes for better visual distinction in the article content.

Refactor useWordPress.ts


27. Me : No, this is not working. Hover effects are working, but blue color and underlines are not ?


Lovable

14:47 on May 24, 2025

Looking at the issue, the problem is that Tailwind’s prose plugin styles are being overridden by the existing text-gray-700class. Let me fix this by adjusting the CSS classes to ensure the link styles take precedence.RestoreCode

Fix: KnowledgeLayout link styling Preview

I’ve fixed the link styling by using the !important modifier (!text-blue-600, !underline, etc.) to ensure the prose link styles override any conflicting classes, and moved the text color to only apply to paragraphs.

Refactor useWordPress.ts


28. Me : links are still not displayed as expected !


Lovable

14:48 on May 24, 2025

Looking at the code, I can see the issue. The !important modifiers in Tailwind prose classes might not be working as expected. Let me check what’s happening and fix the link styling to ensure links are properly displayed with blue color and underlines.RestoreCode

Fix: Improve link styling in KnowledgeLayout Preview

I’ve fixed the link styling by adding a <style jsx> block with CSS that explicitly targets links within the article content, ensuring they display with blue color and underlines as expected.

Lovable

16:37 on May 25, 2025

When you push changes to your connected GitHub repository, Lovable automatically syncs those changes in real-time. The modified preview should be available within a few seconds to a minute after your push is complete.

If you’re not seeing your changes reflected in the preview yet, you can try:

  1. Refresh the preview – Sometimes a simple refresh helps
  2. Check the build status – Look for any build errors in the console that might prevent the changes from appearing
  3. Verify the sync – Make sure your GitHub push was successful and completed

The bidirectional sync between Lovable and GitHub happens automatically, so there’s no need to manually pull or trigger any updates. Your changes should appear in the Lovable editor and preview as soon as the sync completes.

If you’re still not seeing your changes after a minute or two, there might be a build error or sync issue that needs to be resolved.

Integration of NodeJS code into the KI-Léierbud Plesk Server

The Plesk Server has an integrated NodeJS development environment. After several months of programming NodeJS apps, with and without the help of AI, I recommend to code, test, run and build NodeJS apps with your own desktop computer, or with your laptop, and to deploy the final code of an app in a specific sub-domain folder in the Plesk dashboard.

As a development environment, I got the best experience with Linux-Ubuntu or MAC OSX operating systems.

AI-Agent-Cafe

As an first example, I refer to the project AI-Agent-Cafe, created and published on GitHub by Oliver Koos, a friend of Misch Strotz.

To build this app on my Ubuntu Desktop computer with NodeJS installed, I used the following commands in a folder called NPM :

cd NPM
git clone https://github.com/koosoli/AI-Agent-Cafe.git
cd AI-Agent-Cafe
npm install

In the next step I added an .env file with a Google Gemini API KEY to the app files and continued with the command :

npm run dev

The following screenshot shows the logs of the installation and development process :

Now I was able to run the app succesfully in my browser with http://localhost:5173.

To build the app I stopped the local server and executed the command :

npm run build

The build process is shown in the following screenshot :

The result of the build process was the generation of a new folder /dist with the following content :

index.html
assets/
   index-BMa-GLzpv.js
soundfiles/
   chat.mp3
   walking.mp3
   music/
      Menu.mp3
      Pixel-Quest.mp3

The last step was the deployment of these files in the Plesk Dashboard in a subdomain folder. In the past I used the subdomains app1.ki-leierbud.lu and app2.ki-leierbud.lu already for other tests. The next free subdomain was app3.ki-leierbud.lu. With the Plus-Button in the Plesk File Manager it was very easy to upload the two folders and the index.html file. The following figure shows the environment :

Now you can visit https://app3.ki-leierbud.lu.

AI Image Generator

As a second example I used my “Hands On” app “AI Image Generator” available on HuggingFace. With the assistance of Lovable I created a NodeJS app to fetch the image stream with The HuggingFace space API. The app is named ai-image-gen-buddy and automatically synchronized with a private repository in my GitHub account. Because of the privacy I must clone the repository by including my related password in the git clone command.

The next steps are the same as described for the AI-Agent-Cafe. For this reason I will only show the related screenshots in the next figures :

Clone and install NodeJS app
Develop and build NodeJS app
Plesk File Manager app4

There are two files in the assets folder : a Javascript file and a CSS file.

Here is the result when visiting the URL https://app4.ki-leierbud.lu.
