Readme

baked_file_system_mounter

assemble files in assets folder into executable binary use backed_file_system at compile time, then mount it to new file system folder at runtime.

Let us use a kemal as a example.

We save our assets file here

 ╰─ $ tree src/assets/
src/assets/
└── materialize
    ├── css
    │   └── materialize.min.css
    └── js
        └── materialize.min.js

What we want is assemble those assets file into binary when build.

Then, when copy binary to target environment, starting it, will create new folder like this with assets.

╰─ $ tree public
public/
└── materialize
    ├── css
    │   └── materialize.min.css
    └── js
        └── materialize.min.js
3 directories, 2 files

Any files you add to the public directory will be served automatically by Kemal by default.

So, it will load stylesheet correctly when you write ECR template like this.

<html>
  <head>
    <link rel="stylesheet" href="/materialize/css/materialize.min.css" />
  </head>
  <body>
      <%= yield_content "footer" %>
  </body>
</html>

Installation

Add the dependency to your shard.yml:

dependencies:
  baked_file_system_mounter:
    github: zw963/baked_file_system_mounter

Run shards install

Usage

In this example, we mount two folder, one for assets, one for migration.

# src/config/baked_file_system_mounter.cr

require "baked_file_system_mounter"

#
# so, we assemble all files in `src/assets`,`db` into executable binary when we build,
BakedFileSystemMounter.assemble(
  {
    "src/assets" => "public",
    "db" => "db"
  }
)

# we assemble the db into db folder too
# Then mount those files in `src/assets` into `public` folder(will create it if not exists)
# will serve by kemal when server is start.
# mount `db` into `db` folder too for run migrate when server is starting on production..

if APP_ENV == "production"
  STDERR.puts "Mounting from baked file system ..."
  BakedFileSystemStorage.mount
end
