delta-elixir VS nexus-prisma

I'm exploring web stacks to build a multiplayer text editor. Elixir's Delta has been recommended to me.

Definitely checkout Slab’s Operational Transform library Delta as well. I think conventional wisdom is that CRDTs can be really helpful when there is no single source of truth (i.e. a server), but OT can simplify things when there is.

For the particular goal of text collaboration, there are also operational transforms. There is a library maintained by the folks at Slab: https://slab.com/blog/announcing-delta-for-elixir/

Yeah offline or complex client side state management is a good use case for Javascript. There are Hooks and Push Events with Liveview for real time integrations with Liveview in those scenarios. In my experience offline requirements are rare and often in mobile scenarios where a native or Flutter-like approach is a good option.

Complex client side state or collaborative features might use something like https://github.com/slab/delta-elixir or https://www.inkandswitch.com/local-first/ which is where I'd want JS.

Here's a little context on Delta (https://github.com/slab/delta-elixir) and the linked blog post:

Delta is a format to describe documents' contents and how it changes over time. This is a core piece of technology at Slab, that powers our real-time collaboration engine, thanks to the built-in support for Operational Transform (think multiple users working together in Google docs).

Though we've been using it internally for almost 4 years now, we're finally open-sourcing it to the wider Elixir community.

Would love your feedback!

Here's a little context on Delta and the linked blog post:

Defining the exposed GraphQL schema will often involve re-creating our Prisma models using Nexus types, which can be tedious and error-prone. By using the official Prisma plugin for Nexus, we can easily project models from the data layer unto GraphQL types in our API layer.

Indeed, with nexus-prisma you can easily construct your GraphQL schema based on your database schema.
