amber_render_module

Amber is a web application framework written in Crystal inspired by Kemal, Rails, Phoenix and other popular application frameworks. Normally with Amber artifacts for a feature live in directories for the type of artifact, e.g.

src/controllers/post_controller.cr
src/models/post.cr
src/views/post/_form.slang
src/views/post/edit.slang
src/views/post/index.slang
src/views/post/new.slang
src/views/post/show.slang

Which is fine and dandy but with large code bases it is better to place all artifacts for a module of code that implements a feature in the same folder. E.g. for a Post module to handle blog posts

src/modules/post/_form.slang
src/modules/post/edit.slang
src/modules/post/index.slang
src/modules/post/new.slang
src/modules/post/post_controller.cr
src/modules/post/post.cr
src/modules/post/show.slang

Use this shard to add a macro to ApplicationController so you can place all of your code for a feature in a single folder in src/modules (or src/features or however you want to organise your feature modules).

Installation

Add this to your application's shard.yml:

dependencies:
  amber_render_module:
    github: damianham/amber_render_module

Usage

Add the following to config/application.cr:

require "amber_render_module"
require "../src/modules/**"

In controllers in src/modules/ replace render(template_filename) with render_module(template_filename). E.g.

render("index.slang") => render_module("index.slang")

In edit.slang and new.slang in src/replace render(partial) with render_module(partial)

== render(partial: "_form.slang")

becomes

== render_module(partial: "_form.slang")

By default layouts will be rendered from the normal location (src/views/layouts) but you can pass a path to render within a layout from a different location, e.g.

render_module("index.slang", layout = true, nil, path = "src/modules")
# render src/modules/post/index.slang in layout src/modules/layouts/application.slang

render_module("index.slang", layout = "post_layout.slang", nil, path = "src/modules")
# render src/modules/post/index.slang in layout src/modules/layouts/post_layout.slang

You need to add src/modules to the amber watch command so that changes to your module artifacts cause a re-compilation

amber watch -w "./config/**/*.cr" -w "./src/views/**/*.slang" -w "./src/modules/**/*.slang" -w "./src/modules/**/*.cr"

Development

TODO: create a generator for the CLI similar to scaffold to generate the module artifacts in the same folder.
