Ancestry VS Grape

Making some guesses about what you’re trying to do, you’ll have to alter the table schema to do this efficiently. The ‘ancestry’ gem (https://github.com/stefankroes/ancestry ) can do the migration and update your parent_id-based data to enable all its cool features.

Another gem that stores trees and can get a whole sub tree with one query is ancestry: https://github.com/stefankroes/ancestry

Ancestry gem is what I always use for hiarichle data structures: https://github.com/stefankroes/ancestry If I understand what your looking for, it does pretty much exactly what you want.

Ancestry is a great library to organize models in a tree structure.

Ancestry is a gem that allows the records of a Ruby on Rails ActiveRecord model to be organized as a tree structure (or hierarchy). It employs the materialized path pattern and exposes all the standard tree structure relations (ancestors, parent, root, children, siblings, descendants), allowing all of them to be fetched in a single SQL query. 3,136 stars by now

Grape’s support extends to standard conventions, multiple format support, content negotiation, versioning, etc. The complete guide to Grape to develop REST-APIs, test the API and analyze the performance metrics is available on its official GitHub page.

I'm very ambivalent about Grape, but this very much reminds me of something I do really like about it: the param validation. https://github.com/ruby-grape/grape#parameters

I am currently working on developing and api using grape and devise jwt for user user authentication.

Your RN app will be making http requests to your server, so it doesn't really matter what backend language/framework you use. If your React work was also utilizing http requests to fetch data, then there shouldn't be much of a difference. If your backend is a simple JSON api, checkout Grape. You can tack it on to any existing Rails app.

I've benchmarked Grape with YJIT and without it (if want to see the code, visit repo)

Grape is a REST-like microframework written in Ruby programming language. Grape is also considered among the best ruby frameworks and can be used to run on top of Rack or can be used to complement the existing web application frameworks such as Sinatra or Rails. The latter can be done through the DSL-based REST-API for communication. The Grape ruby web framework facilitates efficient and meaningful APIs working in the web application domain.

I love the Grape gem for building APIs - might be worth considering if you are building something new: https://github.com/ruby-grape/grape
