bilder - web app to host photo albums.

Albums are directories with JPEG images that can be managed via rsync/scp.
It finds new albums and reloads their configuration and contents dynamically.
Thumbnails are generated automatically (filename_thumb.jpg).
Basic auth can be enabled per album.
Comes as a single binary.

You can either download a release or get it via

$ go get github.com/fgeller/bilder

Here's a live demo to click around.

Configuration

You can configure bilder via an optional JSON file. You can pass its location to bilder on startup:

$ bilder -config /path/to/your/config.json

It currently supports the following options:

addr default: 0.0.0.0:8173: This is the address that bilder will serve on.
url-path-prefix default: "": This is a prefix that can be added to the assets' paths that are loaded from the browser. This allows bilder to run behind a proxy like nginx (e.g. if you want to use nginx to terminate the HTTPS connection). Consider the path of the demo linked above: https://geller.io/bilder/b/kitties. In this case nginx proxy passes to bilder under the /bilder path which we would set url-path-prefix to:

location /bilder/ {
    proxy_pass http://localhost:8173/;
}

bilder-dir default: "bilder": This is the path of the folder that bilder scans for album directories. In the following example, this directory would contain a single album kitties:

$ find bilder
bilder
bilder/kitties
bilder/kitties/happy.jpg

reload-delay-seconds default: 10: The time in seconds to wait between scans of bilder-dir.
access-log default: "": When set to a file name, bilder logs requests against the /b path in combined log format to the set file.

This is the JSON file that is used for the demo:

{ "bilder-dir": "/home/fgeller/var/bilder", "url-path-prefix": "/bilder", "addr": "0.0.0.0:8173" }

Albums

Each sub-directory of the bilder-dir directory is considered an album if it contains JPG images. Only JPG images are currently supported. You can add more information about the album by adding a bilder.json to the directory. It currently supports the following options:

user default: "", pass default: "": If both are non-empty strings, bilder will use them as credentials to enable basic authentication for this album.
title default: "": Title that should be set for the album, defaults to the directory name.
captions default: null: Map object from file name to caption string (consider the demo example below).
sort-order default: "": Identifies sort order for images, supported: ModTime (newest first), Name (by file name, default).

This is the bilder.json file in the kitties directory of the demo:

{
  "title": "Kitties",
  "captions": {
    "cat-eyes.jpg": "looking",
    "mini-monster.jpg": "rooooar!",
    "yawning.jpg": "Boring!"
  }
}
