Converting Airtable API response to JSON format in React application

I’m working on a React project and need help with handling data from Airtable. I have a function that fetches records from my Airtable base, but I’m having trouble getting the data in the right format.

The function retrieves all records correctly and I can see them in the console, but I can’t figure out how to return the processed data as a proper JSON object. The asynchronous nature of the API call seems to be causing issues.

Here’s my current code:

function fetchTableData(tableName) {
  var dataArray = []
  airtableBase(tableName).select().all()
  .then(
    function (allRecords) {
      for (let index = 0; index < allRecords.length; index++)
        dataArray.push(allRecords[index]._rawJson.fields)
      // console.log(dataArray) works fine here
    });
  // return dataArray returns empty array
}

I need to return the dataArray and convert it to JSON format so I can use it elsewhere in my React components. What’s the best approach to handle this async operation?

You’re encountering a typical Promise resolution problem. The return statement in your function executes before the .then() method completes, resulting in an empty array. I faced a similar challenge when creating a dashboard that retrieved data from various Airtable bases. To handle this, avoid attempting to populate an external array; instead, simply return the Promise itself. You can modify your function like this: return airtableBase(tableName).select().all().then(records => records.map(record => record._rawJson.fields)). This adjustment ensures that the function returns a Promise that resolves with your processed data. Utilize useState and useEffect in your React component to manage the data effectively.

Your function’s returning before the Promise resolves. Make it async and return the Promise properly. Here’s how I fixed this same issue in my React project:

async function fetchTableData(tableName) {
  try {
    const allRecords = await airtableBase(tableName).select().all();
    const dataArray = allRecords.map(record => record._rawJson.fields);
    return dataArray; // Already in JSON format
  } catch (error) {
    console.error('Error fetching data:', error);
    return [];
  }
}

Call it with await inside useEffect or handle with .then() in your React component. The _rawJson.fields data is already JSON format - no conversion needed. I switched to map() instead of the for loop since it’s cleaner for array transformations.

yeah, ur trying to return synchronously from an async op. had this exact problem last week lol. just make ur func return a promise n handle it in the calling component. fetchTableData('myTable').then(data => setMyState(data)) should work fine. no need to convert to JSON since airtable already gives u js objects.

Been there multiple times. Classic async timing issue - your function exits before the promise completes.

I usually handle this with a custom hook for external APIs like Airtable. Keeps things clean and reusable:

function useAirtableData(tableName) {
  const [data, setData] = useState([]);
  const [loading, setLoading] = useState(true);
  
  useEffect(() => {
    airtableBase(tableName).select().all()
      .then(records => {
        const processedData = records.map(record => record._rawJson.fields);
        setData(processedData);
        setLoading(false);
      })
      .catch(err => {
        console.error(err);
        setLoading(false);
      });
  }, [tableName]);
  
  return { data, loading };
}

Then in your component just call const { data, loading } = useAirtableData('myTable'). You get loading states too, which users expect.

Built several dashboards this way and it handles re-fetching automatically when the table name changes.
