Nostalgia

One-way sync (from local folders to cloud) of media items to Google Photos using unofficial API.

• uploads only files with supported extensions
• ignores zero-byte files
• each folder is traversed recursively
• saves already uploaded files to nostalgia.json file in album folder and ignores them on next execution
• concurrent upload (5 streams by default)
• cooldown mechanism and retries on upload failure

Run an app for the following directory:

.
├── 2015.01.16-25 Trip to Portugal
|   ├── IMG_20150118_153701.jpg
|   └── IMG_20150118_152755.jpg
└── 2015.11.24 Home Party
    ├── Videos
    |   ├── GOPR0001.MP4
    |   └── GOPR0010.MP4
    ├── IMG_20150118_153701.jpg
    └── IMG_20150118_152755.jpg

And you will get two albums in Google Photos:

  IMG_20150118_152755.jpg

  GOPR0010.MP4

Why not...

• To save cloud file ID after upload and on re-sync list cloud files and compare their IDs with locally saved IDs
  Because .upload() returns "file ID", while album.fetchPhotoList() returns a list of "album file ID"s. To get "album file ID" after upload you need to parse album.fetchPhotoList() response. Also it won't return you "album file ID" if uploaded file was already present in cloud before upload

• On re-sync to fetch album files and compare local with cloud by file title
  Because album.fetchPhotoList() doesn't return file title. You need to make an additional request per file to get its info which will include title
