Filebrowser + thumbnail viewer + http server

Expanded example based on lxn’s excellent walk win32 libraries https://github.com/lxn/walk filebrowser example, adding many new
features.

Why?

I’m trying to explore golang’s capabilities and performance in developing a multithreaded and memory intensive windows desktop app.
For inspiration and comparison, I used my old application, Antares12 which was built using Delphi2007.
So far golang didn’t disappoint!

Features:

  • Image browser, displaying thumbnail of images in a grid.
  • Image http server, serving thumbnail of images in a folder. Use http://localhost:8080/users/albums or http://localhost:8080/users/photos while the app is running.
  • Very fast and efficient multi threaded thumbnail processing with goroutines and channels.
  • Resizeable thumbnail size.
  • Filesystem/directory monitoring for changes (new/delete/renamed/modified files)

Golang’s features explored here:

  • Goroutine, channels and synchronizations.
  • Maps, slices
  • cgo interfacing with external c libs
  • Database interface with sqlite3
  • Image processing (drawings/transforms)

Additional fabulous golang libraries used here:

Status and observations:

  • Go language constructs comfortably matched object pascal (delphi) constructs.
  • Many low level routines can easily be converted to golang.
  • Goroutines and channels are truly handy in handling concurrent tasks.
  • Performance in performing cpu and memory intensive operations is excellent. Comparable and sometimes better than delphi.
  • Memory comsumption is larger than delphi/32bit, but not by much. No optimization on my part yet.
  • So far so good…
