Assets are not accessible in API-only app about graphiql-rails HOT 14 CLOSED

For those wanting to make this work on the API only rails app.
Add the following to your Gemfile.

gem 'sass-rails'
gem 'uglifier'
gem 'coffee-rails'

And un comment or add the following to your application.rb
require "sprockets/railtie"

from graphiql-rails.

Just got graphiql-rails to work with my Rails 6, API only app, and here are the steps I took:

1. Adding graphiql-rails Gemfile. It works without uglifier, coffee-rails and sass-rails.

group :development do
  ...
  gem "graphiql-rails"
end

and add to routes.rb like in README.

  if Rails.env.development?
    mount GraphiQL::Rails::Engine, at: "/graphiql", graphql_path: "/graphql"
  end

2. Add require "sprockets/railtie" on top of config/development.rb config/application.rb

require "sprockets/railtie"

3. Sprockets will complain that manifest.js is needed. Here is the simplest version that works, based on @MITSUBOSHI changes

--- add to `app/assets/config/manifest.js`
//= link graphiql/rails/application.css
//= link graphiql/rails/application.js

And it works!

anyone managed to solve this on Rails 7 ??

I left out adding the assets related gems (sass-rails, uglifier, coffee-rails) to my API only Rails app (v5.1.2) & graphiql seems to work fine. 😉

For rails 6 create app/assets/config/manifest.js and add

//= link_tree ../images
//= link_directory ../javascripts .js
//= link_directory ../stylesheets .css

from graphiql-rails.

Thanks for following up! I guess this gem depends on sprockets routing being hooked up. Feel free to PR the documentation if you can think of a way to explain that clearly.

@jam35L I need to serve images uploaded using Carrierwave in an API-only app, so I uncommented require "sprockets/railtie" but it's still not working even with sass-rails, uglifier, coffee-rails gems, any ideas?

@yasser-sobhy Please clarify which part is not working. Your API only app is not working or you can't access your images?

@zfhui Did you have your
rails app in api mode?

from graphiql-rails.

Hi.
I have the same issue.
I have Rails API only app.
And i can't add styles with app/assets/stylesheets/application.scss.
I don't see any request for css/js file even after adding gem 'sass-rails', gem 'uglifier', gem 'coffee-rails',
require "sprockets/railtie" and even adding application.html.haml.
rake assets:precompile creates the application...css but not request for that file comes.

from graphiql-rails.

The problem was that i've added application.html.haml not to app/views/layouts/ folder.
Now everything is OK.

Thx @jam35L

I created a PR for this over a year ago, but has been ignored. The fix is pretty simple. My PR has fallen out of sync with main. The maintainers should fix this ASAP as including Sprockets in Rails 7 does not work and is ill advised.
