Asset path problem and question with esbuild and sass - ruby-on-rails

I am using esbuild, rails 7 and sass.
I created the rails app with
rails new testapp -j esbuild -c sass
I am trying to include this npm package https://github.com/lipis/flag-icons and i use this simple example to show a flag at index page:
<span class="fi fi-gr"></span> <span class="fi fi-gr fis"></span>
The flag does now show and I get a debug message:
ActionController::RoutingError (No route matches [GET] "/flags/4x3/gr.svg"):
The rails server serves the application.css file just fine at http://127.0.0.1/assets/application...css.
I can make the flag appear by adding "assets" before the 'flags' by doing this :
http://127.0.0.1/assets/flags/4x3/gr.svg
So, I am confused.
This
<span class="fi fi-gr"></span> <span class="fi fi-gr fis"></span>
forces the server to search the icons in
http://127.0.0.1/flags/4x3/gr.svg
Sorry, I am at a loss:
I copied the flags folder in /app/assets/ and I added
//= link_tree ../flags
in
app/assets/config/manifest.js
but I still get the same message.
Thank you in advance.

How to use tailwind css gem in a rails 7 engine?

How to use tailwind in a rails engine? According to the documentation supplying a css argument to the Rails generator should work
Rails 7.0.2.2 engine generated using
rails plugin new tailtest --mountable --full -d postgresql --css tailwind
This generates the engine with Postgresql but does nothing with tailwind at all, and following manual installation instructions fail too.
Running, as per documentation, bundle add tailwindcss-rails adds tailwind to the gemfile rather than the engines tailtest.gemspec
So after adding the dependency to the gemspec
spec.add_dependency "tailwindcss-rails", "~> 2.0"
and running bundle install does install the engine however the rest of the manual installation fails
then adding the require to lib/engine.rb
require "tailwindcss-rails"
module Tailtest
class Engine < ::Rails::Engine
isolate_namespace Tailtest
end
end
then running the install process fails
rails tailwindcss:install
Resolving dependencies...
rails aborted!
Don't know how to build task 'tailwindcss:install' (See the list of available tasks with `rails --tasks`)
Did you mean? app:tailwindcss:install
Obviously the app:tailwindcss:install command fails too.
So I am probably missing an initializer of some sort in the engine.rb file but no idea on what it should be.
It is the same idea as How to set up importmap-rails in Rails 7 engine?. We don't need to use the install task. Even if you're able to run it, it's not helpful in the engine (see the end of the answer for explanation).
Also rails plugin new doesn't have a --css option. To see available options: rails plugin new -h.
Update engine's gemspec file:
# my_engine/my_engine.gemspec
spec.add_dependency "tailwindcss-rails"
Update engine.rb:
# my_engine/lib/my_engine/engine.rb
module MyEngine
class Engine < ::Rails::Engine
isolate_namespace MyEngine
# NOTE: add engine manifest to precompile assets in production, if you don't have this yet.
initializer "my-engine.assets" do |app|
app.config.assets.precompile += %w[my_engine_manifest]
end
end
end
Update assets manifest:
# my_engine/app/assets/config/my_engine_manifest.js
//= link_tree ../builds/ .css
Update engine's layout:
# my_engine/app/views/layouts/my_engine/application.html.erb
<!DOCTYPE html>
<html>
<head>
<%#
NOTE: make sure this name doesn't clash with anything in the main app.
think of it as `require` and `$LOAD_PATH`,
but instead it is `stylesheet_link_tag` and `manifest.js`.
%>
<%= stylesheet_link_tag "my_engine", "data-turbo-track": "reload" %>
</head>
<body> <%= yield %> </body>
</html>
bundle show command will give us the path where the gem is installed, so we can copy a few files:
$ bundle show tailwindcss-rails
/home/alex/.rbenv/versions/3.1.2/lib/ruby/gems/3.1.0/gems/tailwindcss-rails-2.0.8-x86_64-linux
Copy tailwind.config.js file from tailwindcss-rails:
$ cp $(bundle show tailwindcss-rails)/lib/install/tailwind.config.js config/tailwind.config.js
Copy application.tailwind.css file into any directory to fit your setup:
$ cp $(bundle show tailwindcss-rails)/lib/install/application.tailwind.css app/assets/stylesheets/application.tailwind.css
Because tailwindcss-rails uses standalone executable, we don't need node or rails to compile the stylesheets. We just need to get to the executable itself.
Executable is located here https://github.com/rails/tailwindcss-rails/tree/v2.0.8/exe/. Instead of running the build task https://github.com/rails/tailwindcss-rails/blob/v2.0.8/lib/tasks/build.rake we can just call the executable directly.
$ $(bundle show tailwindcss-rails)/exe/tailwindcss -i app/assets/stylesheets/application.tailwind.css -o app/assets/builds/my_engine.css -c config/tailwind.config.js --minify
Use -w option to start watch mode.
$ $(bundle show tailwindcss-rails)/exe/tailwindcss -i app/assets/stylesheets/application.tailwind.css -o app/assets/builds/my_engine.css -c config/tailwind.config.js --minify -w
The output file should match the name in stylesheet_link_tag "my_engine".
Now that you have a plain my_engine.css file, do with it what you want. Use it in the layout, require it from the main app application.css. The usual rails asset pipeline rules apply.
If you want to put all that into a task, use Engine.root to get the paths.
# my_engine/lib/tasks/my_engine.rake
task :tailwind_engine_watch do
require "tailwindcss-rails"
# NOTE: tailwindcss-rails is an engine
system "#{Tailwindcss::Engine.root.join("exe/tailwindcss")} \
-i #{MyEngine::Engine.root.join("app/assets/stylesheets/application.tailwind.css")} \
-o #{MyEngine::Engine.root.join("app/assets/builds/my_engine.css")} \
-c #{MyEngine::Engine.root.join("config/tailwind.config.js")} \
--minify -w"
end
From the engine directory:
$ bin/rails app:tailwind_engine_watch
+ /home/alex/.rbenv/versions/3.1.2/lib/ruby/gems/3.1.0/gems/tailwindcss-rails-2.0.8-x86_64-linux/exe/x86_64-linux/tailwindcss -i /home/alex/code/stackoverflow/my_engine/app/assets/stylesheets/application.tailwind.css -o /home/alex/code/stackoverflow/my_engine/app/assets/builds/my_engine.css -c /home/alex/code/stackoverflow/my_engine/config/tailwind.config.js --minify -w

Make your own install task if you have a lot of engines to set up:

# NOTE: use default app template, which will fail to modify layout, manifest,
# and the last command that compiles the initial `tailwind.css`.
# It will also add `bin/dev` and `Procfile.dev` which we don't need.
# Basically, it's useless in the engine as it is.
template = Tailwindcss::Engine.root.join("lib/install/tailwindcss.rb")
# TODO: better to copy the template from
# https://github.com/rails/tailwindcss-rails/blob/v2.0.8/lib/install/tailwindcss.rb
# and customize it
# template = MyEngine::Engine.root("lib/install/tailwindcss.rb")
require "rails/generators"
require "rails/generators/rails/app/app_generator"
# NOTE: because the app template uses `Rails.root` it will run the install
# on our engine's dummy app. Just override `Rails.root` with our engine
# root to run install in the engine directory.
Rails.configuration.root = MyEngine::Engine.root
generator = Rails::Generators::AppGenerator.new [Rails.root], {}, { destination_root: Rails.root }
generator.apply template

Update How to merge two tailwinds.
Above setup assumes the engine is its own separate thing, like admin backend, it has its own routes, templates, and styles. If an engine functionality is meant to be mixed with the main app, like a view_component collection, then tailwind styles will override each other. In this case isolating engine styles with a prefix could work:
https://tailwindcss.com/docs/configuration#prefix
The reason that tailwind styles don't mix is because most of the selectors have the same specificity and the order is very important.
So here is an example. Main app with an engine, both using tailwind, both compile styles separately, tailwind configs are only watching one file from the engine and one from the main app, only using #tailwind utilities; directive:
Engine template, that we want to use in the main app, should work fine:
<!-- blep/app/views/blep/_partial.html.erb -->
<div class="bg-red-500 sm:bg-blue-500"> red never-blue </div>
But when rendered in the main app it never turns blue. Here is the demonstration set up:
<!-- app/views/home/index.html.erb -->
<%= stylesheet_link_tag "blep", "data-turbo-track": "reload" %>
<%= stylesheet_link_tag "tailwind", "data-turbo-track": "reload" %>
<!-- output generated css in the same order as above link tags -->
<% require "open-uri" %>
<b>Engine css</b>
<pre><%= URI.open(asset_url("blep")).read %></pre>
<b>Main app css</b>
<pre><%= URI.open(asset_url("tailwind")).read %></pre>
<div class="bg-red-500"> red </div> <!-- this generates another bg-red-500 -->
<br>
<%= render "blep/partial" %>
And it looks like this:
/* Engine css */
.bg-red-500 {
--tw-bg-opacity: 1;
background-color: rgb(239 68 68 / var(--tw-bg-opacity))
}
#media (min-width: 640px) {
.sm\:bg-blue-500 {
--tw-bg-opacity: 1;
background-color: rgb(59 130 246 / var(--tw-bg-opacity))
}
}
/* Main app css */
.bg-red-500 {
--tw-bg-opacity: 1;
background-color: rgb(239 68 68 / var(--tw-bg-opacity))
}
<div class="bg-red-500"> red </div>
<br>
<div class="bg-red-500 sm:bg-blue-500"> red never-blue </div>
^ you can hit run and click "full page". Main app bg-red-500 selector is last so it overrides engines sm:bg-blue-500 selector, media queries don't add to specificity score. It's the same reason you can't override, say, mt-1 with m-2, margin top comes later in the stylesheet. This is why #layer directives are important.
The only way around this is to watch the engine directory when running tailwind in the main app, so that styles are compiled together and in the correct order. Which means you don't really need tailwind in the engine:
module.exports = {
content: [
"./app/**/*",
"/just/type/the/path/to/engine/views",
"/or/see/updated/task/below",
],
}
Other ways I tried, like running 6 tailwind commands for each layer for main app and engine, so that I can put them in order, better but was still out of order a bit and duplicated. Or doing an #import and somehow letting postcss-import know where to look for engine styles (I don't know, I just symlinked it into node_modules to test), but this still required tailwind to watch engine files.
I did some more digging, tailwind cli has a --content option, which will override content from tailwind.config.js. We can use it to setup a new task:
namespace :tailwindcss do
desc "Build your Tailwind CSS + Engine"
task :watch do |_, args|
# NOTE: there have been some updates, there is a whole Commands class now
# lets copy paste and modify. (debug = no --minify)
command = Tailwindcss::Commands.watch_command(debug: true, poll: false)
# --content /path/to/app/**/*,/path/to/engine/**/*
command << "--content"
command << [
Rails.root.join("app/views/home/*"),
Blep::Engine.root.join("app/views/**/*.erb")
].join(",")
p command
system(*command)
end
# same for build, just call `compile_command`
# task :build do |_, args|
# command = Tailwindcss::Commands.compile_command(debug: false)
# ...
end
https://github.com/rails/tailwindcss-rails/blob/v2.0.21/lib/tasks/build.rake#L11
That answer by Alex is really good, i wish i had it when starting out. (But i didn't even have the question to google)
Just want to add two things:
1- a small simplification. I just made a script to run tailwind in the engine
#!/usr/bin/env sh
# Since tailwind does not install into the engine, this will
# watch and recompile during development
# tailwindcss executable must exist (by bundling tailwindcss-rails eg)
tailwindcss -i app/assets/stylesheets/my_engine.tailwind.css \
-o app/assets/stylesheets/my_engine/my_engine.css \
-c config/tailwind.config.js \
-w
2- For usage in an app, that obviously also uses tailwind, i was struggling, since the two generated css's were biting each other and i could not get both styles to work in one page. Always one or the other (app or engine) was not styled right. Until i got the app's tailwind to pick up the engines classes.
Like so:
Add to the app's tailwind.config.js: before the module
const execSync = require('child_process').execSync;
const output = execSync('bundle show my_engine', { encoding: 'utf-8' });
And then inside the content as last line
output.trim() + '/app/**/*.{erb,haml,html,rb}'
Then just include the apps generated tailwind css in the layout, like the installer will. Don't include the engines stylesheet in the layout, or add it to the asset

How to set up importmap-rails in Rails 7 engine?

I have opened an issue in the importmap-rails gem github repository here about this but thought I'd throw the question out here in case anyone might have a workaround
This is what I have discovered so far
A new engine with Rails 7 alpha 2 or Rails 7.0, generated using rails plugin new custom_page --mountable --full generates a new engine that includes the importmap-rails gem in the bundled gems but there is no ability to use it. Adding spec.add_dependency 'importmap-rails' to the enginename.gemspec makes no difference, nor does adding a require importmap-rails to engine.rb. There is no importmap executable in the bin directory.
A call to bundle info importmap-rails
Produces a promising result showing that the gem is installed by default
* importmap-rails (0.8.1)
Summary: Use ESM with importmap to manage modern JavaScript in Rails without transpiling or bundling.
Homepage: https://github.com/rails/importmap-rails
Source Code: https://github.com/rails/importmap-rails
Path: /home/jamie/.rvm/gems/ruby-3.0.0#custom_page/gems/importmap-rails-0.8.1
A call to rails --tasks shows
rails app:importmap:install # Setup Importmap for the app
But I believe this is coming from the test application generated by the --full option rather than being available to the rails command for the engine.
I was expecting to see the same without app: prefix
A call to this task resolves to a template error as shown
rails app:importmap:install
Don't know how to build task 'app:template' (See the list of available
tasks with rails --tasks) Did you mean? app:tmp:create
If there is a workaround solution to this I'd be grateful to hear it and I'm sure others will too. The reason for me wanting this is that I totally failed to introduced webpacker in a rails 6.1.4 engine and I was hoping this was going to be my, much improved, solution
You don't need to use the install task to set up importmaps. All it does is a few copy paste operations and it doesn't really help with the engine set up anyway.
Add importmaps to engine's gemspec file:
# my_engine/my_engine.gemspec
spec.add_dependency "importmap-rails"
Update engine.rb:
# my_engine/lib/my_engine/engine.rb
require "importmap-rails"
module MyEngine
class Engine < ::Rails::Engine
isolate_namespace MyEngine
initializer "my-engine.importmap", before: "importmap" do |app|
# NOTE: this will add pins from this engine to the main app
# https://github.com/rails/importmap-rails#composing-import-maps
app.config.importmap.paths << root.join("config/importmap.rb")
# NOTE: something about cache; I did not look into it.
# https://github.com/rails/importmap-rails#sweeping-the-cache-in-development-and-test
app.config.importmap.cache_sweepers << root.join("app/assets/javascripts")
end
# NOTE: add engine manifest to precompile assets in production
initializer "my-engine.assets" do |app|
app.config.assets.precompile += %w[my_engine_manifest]
end
end
end
Update assets manifest:
# my_engine/app/assets/config/my_engine_manifest.js
//= link_tree ../javascripts/my_engine .js
Add javascript entry point for our engine, if needed. Pins will be available without this file.
# my_engine/app/assets/javascripts/my_engine/application.js
// do some javascript
document.querySelector("h1").innerText = "hi, i'm your engine";
console.log("hi, again");
Update engine's layout:
# my_engine/app/views/layouts/my_engine/application.html.erb
<!DOCTYPE html>
<html>
<head>
<!--
NOTE: This loads/imports main app `application.js` and all the pins from
the main app and from the engine (because we set it up in the engine.rb).
-->
<%= javascript_importmap_tags %>
<!--
NOTE: To add engine's javascript functionality we have to load the
entrypoint here or `import` it in the main app `application.js`
-->
<%= javascript_import_module_tag "my_engine/application" %>
</head>
<body> <%= yield %> </body>
</html>
Create importmap.rb and pin my_engine/application, this name has to match with javascript_import_module_tag. It cannot clash with any other name in the main app, so you can't just use application:
# my_engine/config/importmap.rb
# NOTE: this pin works because `my_engine/app/assets/javascripts
# is in the `Rails.application.config.assets.paths`
pin "my_engine/application"
Some extras to test the setup:
# config/routes.rb
Rails.application.routes.draw do
mount MyEngine::Engine => "/"
end
# my_engine/config/routes.rb
MyEngine::Engine.routes.draw do
get "home", to: "homes#index"
end
# my_engine/app/controllers/my_engine/homes_controller.rb
module MyEngine
class HomesController < ApplicationController
def index; end
end
end
# my_engine/app/views/my_engine/homes/index.html.erb
<h1>Home</h1>
At this point you should have this in your rendered layout's <head> tag, among other things:
<script type="importmap" data-turbo-track="reload">{
"imports": {
"application": "/assets/application-66ce7505c61e3e4910ff16e7c220e1fbfb39251cd82e4bab8d325b3aae987cf9.js",
"my_engine/application": "/assets/my_engine/application-31ce493e8376b4c20703a50f38d419ae309ffe410b7ab7fec47440e02eef08a8.js",
}
}</script>
<script type="module">import "application"</script>
<script type="module">import "my_engine/application"</script>
H1 tag should change to <h1>hi, i'm your engine</h1> on reload.
Additional importmaps can be added manually with https://generator.jspm.io/.
For bonus points, bin/importmap can be customized to work inside the engine. Create a new importmap file inside bin directory.
# my_engine/bin/importmap
#!/usr/bin/env ruby
# NOTE: don't forget to `chmod u+x bin/importmap` to make it executable.
# make sure we are loading the correct versions of things
ENV["BUNDLE_GEMFILE"] ||= File.expand_path("../Gemfile", __dir__)
require "bundler/setup" if File.exist?(ENV["BUNDLE_GEMFILE"])
# NOTE: importmap requires some rails goodness that we don't have in the engine,
# because we don't have `config/application.rb` that loads the environment.
require "rails"
# importmap-rails is not loaded automatically
require "importmap-rails"
# the actual command runner
require "importmap/commands"
Run from inside the engine directory:
$ bin/importmap pin react
Pinning "react" to https://ga.jspm.io/npm:react#18.1.0/index.js
$ cat config/importmap.rb
pin "my_engine/application"
pin "react", to: "https://ga.jspm.io/npm:react#18.1.0/index.js"
I haven't tested it too much, so any feedback would be welcome. Restart the server if something doesn't show up, I don't know how reloading behaves with all this.
I fall back to the old school Javascript include in the html.
<script src="https://cdnjs.cloudflare.com/ajax/libs/jquery/3.6.0/jquery.js"></script>
Well it definitely works on all browser instead of figuring out if the browser supports the feature that I might use later.
I have full control which page to put too... but that might not be what you want...

Image Asset Not Loading In Production

I'm running Rails 5.2.2. I recently separated some admin code from my frontend and in the process moved my controllers, views, css & JS to folders in either frontend or admin respectively.
In development, everything works fine. In production, I am unable to load image assets from my css.scss files using the following line background: url(arrow.png) no-repeat left center; (located in app/assets/stylesheets/frontend/application.css.scss).
My assets has the following file structure:
assets/
config/
images/
admin/
frontend/
products/
another_folder/
javascripts/
admin/
frontend/
stylesheets/
admin/
frontend/
I did not have to change any of my image tags in my views once I made these changes for my images in assets/images/products so I figured that I wouldn't have to do that anywhere else either; things just seemed to work. However, in production the arrow.png returns a 404. When I inspect the image request, the link to the image is /assets/frontend/arrow.png. I use the RAILS_ENV=production flag when compiling assets. I have also run rake assets:clobber with the production flag then tried compiling the assets again. I've deleted all browsing data.
Here are my server logs where the image is requested:
I, [2019-08-01T05:06:22.496953 #6733] INFO -- : [8a0b82c0-c4a3-419f-92fd-8f4a89bbe643] Started GET "/assets/frontend/arrow.png" for 35.188.197.210 at 2019-08-01 05:06:22 +0000

UPDATE:
Adding this to a view works fine in production so I can confirm the asset does indeed compile properly.
<%= image_tag("frontend/arrow.png") %>
For Rails 5, please try to change following configuration:
config.public_file_server.enabled = ENV['RAILS_SERVE_STATIC_FILES'].present?
to
config.public_file_server.enabled = true
OR
you can set RAILS_SERVE_STATIC_FILES true in your passenger_env_var. That will also work.
Helo is this code works for you?
background: image-url(arrow.png) no-repeat left center;

Sass import from rails engine not working

I've created a Rails Engine for assets. I don't use sprockets for css. Instead, I rely on sass's #import. This works perfectly fine in the test/dummy app, but in the Rails app that is requiring the engine, it keeps throwing
Sass::SyntaxError: File to import not found or unreadable: gumby.
I've been at this for a while, and originally the path wasn't in the load path for sass. But then I added
config.sass.load_paths << "#{Gem.loaded_specs['gumby_on_rails'].full_gem_path}/app/assets/stylesheets"
to my config/application.rb and now it definitely shows the correct path to the file I'm trying to import. It is the second to the last path listed in the following trace:
Sass::SyntaxError: File to import not found or unreadable: gumby.

The rails engine's tree looks like this
app/
assets/
stylesheets/
gumby/
...
gumby.css.scss
(I know that technically you should namespace all your assets in an engine, but I didn't want to have gumby/gumby, and I feel the chances of a name clash are slim.)
So in the test/dummy app I can import this file via #import 'gumby';, but this fails in the Rails app. With the above exception. How do I get this working?
And by the way, this is a Rails 4.1 app, and the answers to several other "similar" questions are all due to using groups in the Gemfile. Rails 4 got rid of groups so this is not the problem/solution.
So the solution for me was to suck it up and namespace it gumby/gumby. Then I also had to change the config/application.rb to:
config.assets.paths << "#{Gem.loaded_specs['gumby_on_rails'].full_gem_path}/app/assets/stylesheets"
And for some reason modular-scale wasn't being required properly, even though the engine already required it. So I had to change application.css.scss to application.css.scss.erb and put <% require 'modular-scale' %> at the top.
then you should write it like this :
config.sass.load_paths << "#{Gem.loaded_specs['gumby_on_rails'].full_gem_path}/app/assets/stylesheets/gumby"
or try this (untested)
#import_tree 'gumby';

Error compiling CSS asset (Compass + Sass + Heroku)

I have a site running on Heroku using Compass with Saas an is working fine (compiling assets when pushing to Heroku seems to be fine).
I added a new folder inside assets to namespace other styling, like this
/app/assets/stylesheets/site/site1.css
/app/assets/stylesheets/site/site2.css
/app/assets/stylesheets/site/common/base.css.saas
/app/assets/stylesheets/site/site/site1.css.saas
/app/assets/stylesheets/site/site/site2.css.saas
...
The problem is when I visit a page that use site1.css styling I get the following error
Error compiling CSS asset
Sass::SyntaxError: File to import not found or unreadable: ../compass/css3/text-shadow.
Load path: /app
(in /app/app/assets/stylesheets/site/common/base.css.sass)
/app/app/assets/stylesheets/site/common/base.css.sass)
The line that the error refers is this
/app/assets/stylesheets/site/common/base.css.sass
#import "../compass/css3/text-shadow"
I tried both "../compass/css3/text-shadow" and "compass/css3/text-shadow". In both cases I got the same error.
Any idea how to solve this?
Solved.
I needed to specify on production.rb file the additional files to compile
config.assets.precompile +=
Dir["#{Rails.root}/app/assets/stylesheets/site/site/*.*"].collect {|s| "site/" + File.basename(s).gsub(/.scss|.sass/, '') }
Now is working fine.
