Rails 7.1 Released
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

The GraphQL N+1 Problem and SQL Window Functions
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.

What Would be Your Ideal Ruby Tech Stack
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 APIs in Rails
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:

Anyone here turned their rails app into an API?
If you do go the API route though, strongly consider using GraphQL with the (graphql-ruby)[https://graphql-ruby.org/] gem.

How to work with an external front-end developer?
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

Ask HN: What tool(s) do you use to code review and deploy SQL scripts?
A regular code repo with the scripts (with pull/merge requests for review) and then a CI job that builds containers with something like dbmate https://github.com/amacneil/dbmate that can then be run against any staging/prod environment.

Level UP your RDBMS Productivity in GO
As we want to maintain the track of our changes to the DB, we are going to use migrations. In this case, we are going to use dbmate. But, you can use any other tool you want.

Rails 7.1 Released
> For example having database migrations built in etc.
I actually went the exact opposite route, at least when possible: https://github.com/amacneil/dbmate
Pure SQL migrations, regardless of the back end technology that you use, completely decoupled from how each framework/library views things and therefore not dependent on them (you could even rewrite the back end in another technology later on, if needed; or swap ORMs; or avoid issues when there's a major ORM version update).
It's really nice when you can generate entity mappings based on a live database, like with https://blog.jetbrains.com/dotnet/2022/01/31/entity-framewor...
So in my case, I can have:
* a DB that has migrations applied with dbmate, completely decoupled from any back end(s) that might use it

How do your teams run DB migrations?
You can run dbmate as part of your CI/CD pipeline. You just keep a dbmate directory in your repo and deploy migrations with your code.

Working with TypeORM 0.3x with Nestjs - I wasn't aware so many people were facing issues with it
In general with ORMs, you will face a problem in one way or another. I ended up simply using https://github.com/gajus/slonik and https://github.com/amacneil/dbmate for migrations. My life is way much better since then.

what do you use for migrations? or how do you the sql tables and seeding?
I like dbmate, super simple and straightforward to use. For your specific use case, it can also be configured using your .env!

New post: Is Prisma better than your 'traditional' ORM?
Would always go for a language agnostic migration tool, e.g. https://github.com/amacneil/dbmate to stay flexible and stay away from lock-in effects (besides sql).
- I greatly dislike ORMs, but I find myself wanting ORM agnostic SQL migration tools. What do you use to perform RDBMS table migrations outside of an ORM?
