What's the best way to retrieve Gmail messages in chronological order with Node.js API?

I’m working on a Node.js application that needs to fetch Gmail messages and display them sorted by date. I have the basic connection working but I’m not sure how to properly sort the results.

Here’s my current approach:

function fetchGmailMessages(userEmail, authToken, callback) {
    const gmail = google.gmail({ version: 'v1', auth: authToken });
    
    gmail.users.messages.list({
        userId: userEmail,
        auth: authToken,
        maxResults: 50
    }, callback);
}

The function works but the messages come back in random order. I need them sorted chronologically so the newest emails appear first. Should I add a query parameter or handle the sorting after getting the response? Any suggestions would be helpful.

It seems the issue lies in how you’re managing the asynchronous calls after retrieving the message IDs. The Gmail API indeed provides IDs in chronological order, but when fetching message details simultaneously, you might lose that order. I’ve encountered this before, and a practical solution is to maintain the original indices from the list response. Once you’ve received the full message details, you can reorder them based on these indices. Additionally, keep in mind the rate limits of the API; consider implementing a delay between requests or using batch processing to prevent issues with request timing.

gmail api actually sorts msgs by date, but if ur threading them, it can cause some mixing up. include includeSpamTrash: false and q: '' in ur params. also ensure ur callback function isn’t doing any extra sorting that could mess it up.

Gmail API returns messages in reverse chronological order by default, so if you’re seeing random ordering, there’s likely an issue with how you’re processing the response. The messages.list endpoint only gives you message IDs - you need separate messages.get calls for each ID to get the actual message data and timestamps. That’s probably where your ordering gets mixed up. I hit this same issue last year. The randomness came from fetching individual messages asynchronously. Use Promise.all or process them sequentially to keep the original order from the list call. Also double-check you’re not accidentally reordering them in your frontend code.
