How to integrate Lovable with Etsy API?

Adding the Axios Library Dependency via Code

In Lovable we cannot run terminal commands, so instead we add a script tag inside your main HTML file (usually index.html) to include Axios from a CDN. Open your index.html file and add the following line inside the <head> section:


<script src="https://cdn.jsdelivr.net/npm/axios/dist/axios.min.js"></script>

This makes the Axios library available globally in your project for making HTTP requests.

Creating an API Utility File for Etsy Integration

Create a new TypeScript file to manage communication with the Etsy API. For example, create a new file named etsy.ts inside a folder called src/api (if you do not have an api folder, simply create one).

Inside etsy.ts paste the following code snippet:


import axios from 'axios';

// Replace with your actual Etsy API key
const ETSYAPIKEY = 'YOURETSYAPI_KEY';
const BASE_URL = 'https://openapi.etsy.com/v2';

export async function getActiveListings() {
  try {
    const response = await axios.get(${BASE_URL}/listings/active, {
      params: {
        apikey: ETSYAPI_KEY,
        // Add additional parameters here if needed. For example:
        // limit: 10,
        // offset: 0
      }
    });
    return response.data;
  } catch (error) {
    console.error('Error fetching Etsy listings:', error);
    throw error;
  }
}

Explanation:
• The code imports Axios for making HTTP requests.
• It defines your Etsy API key and the base URL used to access Etsy’s public endpoints.
• The exported getActiveListings function makes a GET request to Etsy’s endpoint for active listings while allowing you to pass additional parameters.
• Error handling is included to report any issues in fetching data.

Integrating the Etsy API Call into Your Lovable Project

To display or process the data from Etsy’s API in your Lovable project, modify your main TypeScript file (for example, main.ts) by importing and calling the function defined in etsy.ts.

Append the following code to your main file where you want the Etsy data to be fetched and used:


import { getActiveListings } from './api/etsy';

async function fetchAndDisplayListings() {
  try {
    const listings = await getActiveListings();
    console.log('Etsy Listings:', listings);
    // Here you can integrate the fetched listings into your UI.
    // For example, updating an element's innerHTML or rendering components.
  } catch (error) {
    console.error('Failed to fetch listings:', error);
  }
}

// Trigger the API call when your application starts or at an appropriate event.
fetchAndDisplayListings();

Explanation:
• The code imports the getActiveListings function from your newly created etsy.ts file.
• It defines a helper function fetchAndDisplayListings that calls the Etsy API function, logs the results, and serves as the place to write further UI integration logic.
• Upon invocation, the function fetches the active listings and logs them to the console.

Updating UI Elements with Fetched Data

If you wish to directly update UI components within your Lovable project once the Etsy data is received, insert code similar to the following snippet after fetching the listings. Insert this code into the same block inside your main TypeScript file:


async function fetchAndDisplayListings() {
  try {
    const listings = await getActiveListings();
    console.log('Etsy Listings:', listings);
    // Assume you have an HTML element with id "etsyListings" to show the data.
    const listingsElement = document.getElementById('etsyListings');
    if (listingsElement && listings.results) {
      listingsElement.innerHTML = listings.results.map(item =>
        <div><h2>${item.title}</h2><p>${item.description}</p></div>
      ).join('');
    }
  } catch (error) {
    console.error('Failed to fetch listings:', error);
  }
}

fetchAndDisplayListings();

Explanation:
• This enhanced code snippet assumes there is an HTML container (for example, a div with id “etsyListings”) where you want to display the active listings.
• The code maps through the results obtained from Etsy, creates HTML for each listing, and injects the content into the container element.

Final Integration Check

Ensure that:

You have saved all changes within index.html, etsy.ts, and your main TypeScript file (for example, main.ts).
The API key in etsy.ts is replaced with your actual Etsy API key.
You have an HTML element (like a div with id "etsyListings") defined in your index.html where the listings will be rendered. For example, add the following to the body of your index.html:
```
<div id="etsyListings"></div>
```

After these steps, your Lovable project will be configured to integrate with the Etsy API using TypeScript, make HTTP calls via Axios, and display the fetched data within your application.
