What is this?

This script is for logseq webapp users that want to switch to the local version.

It will download all images that are linked inside your graph and store them in the local "/assets/" folder.

Remarks

1. Only supports Markdown files (for now)

2. Filnames are not preserved. The filenames will be a news random string. (Let me know if you need it otherwise.)

2. Make sure you close Logseq Desktop app and disconnect web app before starting!

3. Use at your own risk! Verify everything worked before permanently moving to the new local version!

How to use

1. Download your logseq repository from Github to your local machine.

2. Run the script with "-f "

3. Reccomended if you know how: Check the uncommitted changes to the repository. This is an easy way to check if everything worked as intended.

3. Open that folder in the logseq client.
