baked_file_handler

A Kemal handler for serving files baked into the application.

Installation

1. Add the dependency to your shard.yml:

   dependencies:
     baked_file_handler:
       github: ralsina/baked_file_handler

2. Run shards install

Usage

require "kemal"
require "baked_file_system"

# Example BakedFileSystem class
class MyAssets
  extend BakedFileSystem
  bake_folder "./public_assets"
end

add_handler BakedFileHandler::BakedFileHandler.new(MyAssets)

Kemal.run

Compression Support

The handler automatically serves compressed versions of files when available and supported by the client.

How it works:

1. Check the Accept-Encoding header for supported compression methods
2. Look for compressed versions of files with .br (Brotli) or .gz (gzip) extensions
3. Serve the compressed version with appropriate Content-Encoding header
4. Fall back to uncompressed files if no compressed version exists

Priority:

1. Brotli (.br) - preferred when client supports it
2. Gzip (.gz) - used when client supports gzip but not Brotli
3. Uncompressed - fallback when no compression is supported

Example:

If you have both style.css and style.css.gz baked into your assets:

• Request with Accept-Encoding: gzip will serve style.css.gz with Content-Encoding: gzip
• Request with no compression support will serve style.css normally

Development

I don't expect this need much further development. In any case, it's simple enough code :-)
