Static handlers

Purpose

Static handlers are a built-in REST handler for serving files. They are available as a convenience and provide fast file serving with proper cache handling.

Usage

Static handlers are pre-written REST handlers. They only need to be specified in the routing information with the proper options.

The following example routing serves all files found in the priv_dir/static/ directory of the application. It uses a mimetypes library to figure out the files' content types.

Dispatch = [
	{'_', [
		{['...'], cowboy_static, [
			{directory, {priv_dir, static, []}},
			{mimetypes, {fun mimetypes:path_to_mimes/2, default}}
		]}
	]}
].
