Simple website which display photos stored on a HDD. Features :

• Present folders as tree folder
• Display a thumbnail and lightbox to show pictures
• Possible to select pictures to delete (by moving in garbage)
• Possible to update a specific folder
• Possible to add a folder (api rest : /addFolder)

When indexing pictures, create two resized : 250 px and 1080 px height. Images are also rotated cause Chrome can't use exif orientation.

I extract date from exif to sort images in view.

The light server is written in Go. The front is written in React

• react-grid-gallery
• ant design

To build front :

• npm install
• npm run-script build

After that, use build as resources.

Goland dependencies :

• github.com/disintegration/imaging : Rotation images
• github.com/nfnt/resize : Resize images
• github.com/dsoprea/go-jpeg-image-structure
• github.com/rwcarlsen/goexif/exif : Exif reader
• github.com/dsoprea/go-exif/v2 : Exif writer

Build : go build main/photos_server_run.go

To run server, specify yaml configuration file with -config option. Configuration Yaml File :

cache: <specify where reduced images must be saved (mandatory)>
resources: <folder where build front resources are (mandatory)>
port: <to ovveride default port (9006)>
garbage: <folder where to move deleted files>
upload-folder: <folder where to upload pictures>
override-upload: <folder name to prefix upload>
security:    
  mask-admin: <mandatory to use garbage, mask on referer. Used to protect admin operation to be launch only at home on personal network>
  secret: <key used to sign jwt Token (HS256) (https://mkjwk.org/ > oct / HS256)>
  oauth2:
    provider: <oauth2 provider. Only google at this time>
    client_id: <client id on cloud provider>
    client_secret: <client secret on cloud provider>

      run: <command to run> 

Server run on port 9006

Https is not enabled cause I'm using secured proxy in front.

At home, server run on Raspberry Pi 2 with an old SAN. Indexation is quite slow but after that, displaying is very fast.
