Lovable & Naden: Building Web Apps Without Code

This note summarizes a video tutorial demonstrating how to build a web application using Lovable for the frontend and Naden for the backend. The tutorial focuses on building a simple "excuse generator" app.

Key Highlights:

No-code web app development: Build a functional web app without writing any code using Lovable's intuitive interface and Naden's workflow automation.
Natural language prompts: Interact with Lovable using simple instructions in plain English to design and modify the web app.
Backend integration with Naden: Connect Lovable to a Naden workflow to process user input, utilize AI agents, and return dynamic responses.
AI-powered excuse generation: Use an AI agent within Naden to generate creative excuses based on user-submitted problems and a chosen tone.
Dynamic level system: Implement a leveling system that rewards users with points for submitting problems.
Real-time interaction and updates: See changes reflected immediately in the Lovable preview as you modify the app.

Detailed Breakdown of the Process:

Lovable Frontend Development:
- Start by giving Lovable a simple prompt describing the desired web app. For example, "Create a web app where users can submit problems."
- Provide design inspiration using images or descriptions of existing landing pages.
- Use natural language prompts to make changes to the design and functionality of the app, such as adding a logo, simplifying the layout, or changing colors.
- Create a form for users to submit their problems.
Naden Backend Setup:
- Create a new workflow in Naden.
- Add a Webhook node to trigger the workflow when data is received from Lovable.
- Copy the Webhook URL.
Connecting Lovable and Naden:
- In Lovable, instruct it to send the user-submitted problem to the Naden Webhook URL via a POST request when the submit button is clicked.
- In Naden, set the Webhook method to POST.
Setting up the AI Agent in Naden:
- Add an AI Agent node to the workflow.
- Configure the agent to receive the user's problem as input.
- Provide a system message to instruct the agent on its role (e.g., creating excuses).
- Connect an OpenAI chat model to the agent (requires an OpenAI API key).
- Test the agent to ensure it's generating appropriate excuses.
Sending the Response back to Lovable:
- Add a "Respond to Webhook" node in Naden.
- Configure the Webhook node to respond using the "Respond to Webhook" node instead of responding immediately.
- In Lovable, instruct it to wait for the Webhook response and display it in a dedicated field (e.g., "Here's your excuse").
- Clean up the JSON response from the Webhook to display only the relevant output (the excuse).
Adding Features and Functionality:
- Implement a dynamic level system in Lovable. Increase the user's level after submitting a certain number of problems.
- Add a dropdown menu to allow users to select the tone of the excuse (e.g., realistic, funny, ridiculous, outrageous).
- Pass the selected tone to Naden along with the problem.
- Update the AI agent's system message to account for the different tones and generate appropriate excuses.
Activating the Workflow:
- Switch the Naden workflow from "Test" to "Active".
- Copy the production Webhook URL.
- Update the Webhook URL in Lovable.
Publishing the App:
- Once you are satisfied with your web app, publish it using a custom domain or the provided Lovable domain.
