mdfb 1.3.1

A CLI for downloading posts in bulk from Bluesky from specified a account

mass-downloader-for-bluesky

mass-downloader-for-bluesky (mdfb) is a Python cli application that can download large amounts of posts from bluesky from any given account.

Installation

You will need Python to be installed to use this CLI.

You can install via pip by:

pip install mdfb

Manual

Have Poetry installed.

Then clone the project, open a poetry shell and then install all dependencies.

git clone [e-mail]:IbrahimHajiAbdi/mass-downloader-for-bluesky.git
cd mdfb
poetry shell
poetry install

Usage

mdfb works by using the public API offered by bluesky to retrieve posts liked, reposted or posted by the desired account.

mdfb will download the information for a post and the accompanying media, video or image(s). If there is no image(s) or video, it will just download the information of the post. The information of the post will be a JSON file and have lots of accompanying data, such as the text in the post, creation time of the post and author details. Currently, the retrieved posts start from the latest post to the oldest.

You will need to be inside a poetry shell to use mdfb if installed manually

Examples

Some example commands would be:

mdfb download --handle bsky.app -l 10 --like --threads 3 --format "{RKEY}_{HANDLE}" ./media/

mdfb download -d did:plc:z72i7hdynmk6r22z27h6tvur --archive --like --threads 3 --format "{DID}_{HANDLE}" ./media/

mdfb download --handle bsky.app --update --like --threads 3 --format "{RKEY}_{HANDLE}" ./media/

Naming Convention

By default, mdfb's naming convention is: "{rkey}_{handle}_{text}". If it is downloading a post with multiple images then the naming will be: "{rkey}_{handle}_{text}_{i}", where "i" represents the order of the images in the post ranging from 1 - 4. In addition, the filenames are limited to 256 bytes and will be truncated down to that size.

However, you can specify the name of the files by using the --format flag and passing a valid format string, e.g. "{RKEY}_{DID}". You can put anything in the format string inbetween the keywords. This is case-sensitive.

For --format, the valid keywords are:

• RKEY
• DID
• HANDLE
• TEXT
• DISPLAY_NAME

Download Amount

When specifying the limit, this will be true for all types of post downloaded. For example:

mdfb download --handle bsky.app -l 100 --like --repost --post ./media/

This would download 100 likes, reposts and post, totalling 300 posts downloaded.

Furthermore, you can archive whole accounts. For exmaple:

mdfb download --handle bsky.app --archive --like --repost --threads 3 --format "{DID}_{HANDLE}" ./media/

This would download all likes and reposts.

Database

When downloading posts, mdfb inserts into the database some post identifiers. This allows for you to download only new posts from an account that you haven't downloaded yet.

However, there are some constraints, if you delete a file, this is not reflected in the database and thus, if you use the --update flag, it will not redownload it. Furthermore, the posts identifiers are only committed to the database once all posts have been downloaded, so if mdfb topples over during downloading, none of the posts downloaded will be reflected into the database.

The database is stored in: (Linux) ~/.local/share/mdfb/, (Windows) C:\\Users\\$USER\\AppData\\Local\\mdfb and (macOS) /Users/$USER/Library/Application Support/mdfb.

Example

mdfb db --delete_user bsky.app

Note

The maximum number of threads is currently 3, that can be changed in the mdfb/utils/constants.py file. Furthermore, there are more constants that can be changed in that file, such as delay between each request and the number of retires before marking that post as a failure and continuing.
