Is it possible or easy to add an option to select multiple labels and create folders under ./files?
We have a few hundred labels to go through one by one and create a folder for each and then download the files to be sorted.

I tried both "from:" and label approach, the result is same.

If the email has multiple attachments (in my case, they are all images), only the first one will be downloaded.

Also, when I'm using the "from:" filter, it's even worse: I found at least one email wasn't downloaded at all (it's exactly the 51th one out of 51 emails that isn't downloaded, not sure if relevant.)

Initial plan is to organise it more better.

• Use database to manage downloaded files.
• Avoid duplicate download of same file

Would be nice to combine date range filtering in addition to labels. ie: before:2004/04/18, after:04/16/2004. Might require some refactoring for the CLI to support a combination of filters, perhaps a series of questions:

1. filter by mailId
2. filter by label
3. filter by before
4. filter by after

if none are selected, then they'll get 'all'

Docs:
https://developers.google.com/gmail/api/guides/filtering
https://support.google.com/mail/answer/7190

Use case: I only want to save pdfs. Right now, I'm running cd files && rm -- ^*.pdf in zsh after running this script, in order to remove the unwanted files.

This could instead be filtered during the query using filename:pdf as per the docs.

There is, however, one problem with only modifying the query: if an email has more than one attachment, both will still get downloaded. To make this function as expected, there would also need to be logic in function fetchAndSaveAttachment() to filter out unwanted files.

hello, firstly I'd like to say nice project!

I tried using it and it found the label I was looking for, it found all the emails under the label but it didn't find any attachments

I traced the problem to index.js, line 189 in the function pluckAllAttachments

      if (!p.body || !p.body.attachmentId) {
        return undefined;
      }

It seems not all messages that have attachments, have an attachmentId. Sometimes they are found in the same object but in the data key. See gmail api https://developers.google.com/gmail/api/reference/rest/v1/users.messages.attachments

it seems the messages that are causing the problem have nested parts which contain the relevant attachmentId

The messages in question were forwarded with an iPad FWIW

EDIT: removed something I was wrong about, added what the actual problem was 😅

Since the goal is to only get emails with attachments, the query can be structured with has:attachment, as per these docs.

The result shouldn't be any different, but it will probably have significant performance improvement to include that.

I received a Google email with the subject line "Migrate your OAuth out-of-band flow to an alternative method before Oct. 3, 2022" on May 3, 2022. It identified to OAuth credentials created for this tool as being impacted.

https://developers.googleblog.com/2022/02/making-oauth-flows-safer.html#disallowed-oob

Please consider updating the tool to use an allowed OAuth mechanism.

I get this error with any search with more than a few emails:

It'll be great if this library could throttle itself to stay within Gmail's API limits!

Planning to use UI based application for end user. So, no need to code and enhance UX. Currently, I plan to use Electron as we can get two benefits

1. Cross platform
2. Portable

My gmail currently has ~300 emails. The files directory was empty even after the script said Done.

I modified return getAllMails(auth, 500) to return getAllMails(auth, 100), and was able to get files.

I see two problems with the code:

1

I think that this is causing the bug.
https://github.com/munir131/attachment-downloader/blob/master/index.js#L285-L292
If there's only one page, messageIds will be an empty array. It also looks like the last page is being skipped even when a user has over 500 emails, since messageIds.concat( is only being called when there's a nextPageToken.

Perhaps

      if (response.data) {
        messageIds = messageIds.concat(response.data.messages)
        if (response.data.nextPageToken) {
           spinner.text = "Reading page: " + ++pageCounter
           resolve(getAllMails(auth, maxResults, response.data.nextPageToken))
         }
      }

      spinner.text = "All pages are read"
      resolve(messageIds)

function getListOfMailIdByLabel(...) looks like it may not have the same issue, since message ids are being added to the array in both conditions.

When I tried my above code, there were more attachments, which confirms that the current code is missing a page.

maxResults isn't being passed down to the recursive function, but instead, 500 is being used for all subsequent pages after the initial.
https://github.com/munir131/attachment-downloader/blob/master/index.js#L288
Should be resolve(getAllMails(auth, maxResults, response.data.nextPageToken))

I get the following error:

This fixed the error, but I don't know if it's the "correct" fix:

Hello!
Is it possible to download attachments linked from google drive?
Seems like now it doesn't.
