docker-rails-example VS graphql

I took a 13,000 line Rails 7.0 app and updated it to 7.1. I had to change 1 line of test configuration code to make everything work.

I would say that's a success for having an easy upgrade path. Now the fun part is going back to refactor some of the code to use the new features in 7.1.

If anyone is curious, I updated my Rails / Docker example app to use 7.1 too https://github.com/nickjj/docker-rails-example. Even though Rails 7.1 comes with a Dockerfile, there's still a lot of opinions you can add such as using Docker Compose to have a fully working out of the box experience that works in development and production -- complete with Postgres, Redis, Action Cable, Sidekiq and more.

Even though Rails 7.1 comes with a Dockerfile, there's still a lot of opinions you can add such as using Docker Compose to have a fully working out of the box experience that works in development and production.

If anyone is interested in that, I updated my example Rails app https://github.com/nickjj/docker-rails-example to use Rails 7.1 a few hours after 7.1 dropped.

If you're itching for Docker compatibility I maintain https://github.com/nickjj/docker-rails-example.

There's https://github.com/nickjj/docker-rails-example if you're looking for an end to end 1 command solution that works in dev and prod. It pulls together Puma, Sidekiq, Action Cable, Postgres, Redis, esbuild and Tailwind. It's all set up and ready to use Hotwire as well.

If anyone is looking for a more complete guide I put together this a while back: https://nickjanetakis.com/blog/a-guide-for-running-rails-in-...

The post also includes a ~1h hour ad-free YouTube video. It includes running Rails and also Sidekiq, Postgres, Redis, Action Cable and ties in esbuild and Tailwind too. It's all managed by Docker Compose.

The example app is open source at https://github.com/nickjj/docker-rails-example and it's optimized for both development and production. No strings attached.

If you're interested I've created https://github.com/nickjj/docker-rails-example with a base project using Docker Compose, Postgres, Redis, Sidekiq, Tailwind and esbuild.

I create an Up controller https://github.com/nickjj/docker-rails-example/blob/main/app/controllers/up_controller.rb and then have Uptime Robot https://uptimerobot.com/ hit it every few minutes.

My memory is fuzzy, but...

1. all data flow through the rails app (no pre-signed s3 upload or download links for direct uploading).

2. no support for CDNs (I think newer rails versions added support)

3. blobs and attachments were unnecessary abstractions.

3a. Querying was annoying and easy to add n+1 queries.

3b. Images are moderated and it was unclear where to put the moderation metadata (on blobs? attachments? create a new table? why so many tables?). Accessing the data was annoying (you need extra joins).

4. GraphQL gem didn't support it: https://github.com/rmosolgo/graphql-ruby/issues/1777

In our Rails application, we use the popular graphql Ruby gem to resolve GraphQL queries. When used naively, it essentially resolves queries as a depth-first tree traversal, which leads to the N+1 problem in GraphQL.

If you're comfortable on the react/client side with graphql, I'd highly recommend plugging in https://graphql-ruby.org/

We use GraphQL, and Ruby GraphQL doesn't allow you to stream the result, it buffers it before sending back the request and there are no alternative. See my issue https://github.com/rmosolgo/graphql-ruby/issues/3969 -- Sadly there is only one library for GraphQL in Ruby.

graphql-ruby is a Ruby gem that implements the GraphQL specification and functionalities.

The next step is to add the GraphQL gem to our Gemfile; you can visit its page, graphql-ruby, for more details; now, open your Gemfile and add this line:

If you do go the API route though, strongly consider using GraphQL with the (graphql-ruby)[https://graphql-ruby.org/] gem.

GraphQL saves you time designing versioned REST endpoints. It self documents. Documentation isn't optional for serious web development so this is a huge win. The rails gems have gotten really good at picking up associations as well since I looked into a couple years ago. https://graphql-ruby.org

When it comes to implementing a GraphQL server in Rails, one can use the excellent GraphQL Ruby gem.
