JavaScript: Updating Airtable API endpoint on button click?

I’m working with the Airtable API and need some help updating the endpoint on a button click. Currently I have a simple script that constructs the API URL using variables for things like the API key and a pagination offset. When a user clicks the ‘Next Page’ button, the offset should update so that the API returns a new set of records. Here’s an example of my code:

let offset = '';
const baseUrl = 'https://api.airtable.com/v0/myAppId/Coupons';
const apiKey = 'myApiKey';

function getApiUrl() {
  return `${baseUrl}?api_key=${apiKey}&maxRecords=10&offset=${offset}`;
}

async function fetchData() {
  const response = await fetch(getApiUrl());
  const data = await response.json();
  // Process data here
}

function handleNextPage() {
  // How can I update the offset here for the next API call?
  console.log('Next page clicked');
}

document.getElementById('nextButton').addEventListener('click', handleNextPage);

fetchData();

The goal is to modify the handleNextPage function to correctly update the offset variable. Any suggestions to improve the code structure or handling of pagination would be great. Thanks in advance!

hey there! i can help with that. in ur handleNextPage function, u need to update the offset based on the previous API response. usually, Airtable returns an ‘offset’ value in the response. So, modify fetchData to store that:

async function fetchData() {
  const response = await fetch(getApiUrl());
  const data = await response.json();
  offset = data.offset; // Store new offset
  // Process data here
}

afterwards, call fetchData() in handleNextPage. this should update the offset for the next api call. hope this helps!

I’ve dealt with similar Airtable API pagination issues before. Here’s what worked for me:

Modify your fetchData function to return the data it receives. Then, in handleNextPage, call fetchData and use the returned offset for the next request. Something like this:

async function fetchData() {
const response = await fetch(getApiUrl());
const data = await response.json();
return data;
}

async function handleNextPage() {
const data = await fetchData();
if (data.offset) {
offset = data.offset;
await fetchData(); // Fetch the next page
// Update your UI here
} else {
console.log(‘No more records’);
}
}

This approach ensures you’re always using the most recent offset. Remember to handle cases where there are no more records to fetch. Also, consider adding error handling for API requests to improve reliability.

I’ve implemented Airtable API pagination in several projects, and here’s an approach that’s worked well for me:

Consider restructuring your code to use a class. This allows you to encapsulate the API logic and maintain state more effectively:

class AirtableManager {
  constructor(baseUrl, apiKey) {
    this.baseUrl = baseUrl;
    this.apiKey = apiKey;
    this.offset = '';
  }

  getApiUrl() {
    return `${this.baseUrl}?api_key=${this.apiKey}&maxRecords=10&offset=${this.offset}`;
  }

  async fetchData() {
    const response = await fetch(this.getApiUrl());
    const data = await response.json();
    this.offset = data.offset || '';
    return data;
  }

  async handleNextPage() {
    if (this.offset) {
      const data = await this.fetchData();
      // Update UI with new data
      return data;
    }
    return null; // No more pages
  }
}

const manager = new AirtableManager('https://api.airtable.com/v0/myAppId/Coupons', 'myApiKey');
document.getElementById('nextButton').addEventListener('click', () => manager.handleNextPage());

manager.fetchData(); // Initial data fetch

This approach provides better organization and makes it easier to manage the API state across multiple functions.
