A type-safe typescript SQL query builder

Project mention: Show HN: Tsynamo – Type-friendly DynamoDB query builder for TypeScript | news.ycombinator.com | 2024-04-10

Hello HN! I was recently introduced to Kysely (https://github.com/kysely-org/kysely), a type-safe Typescript SQL query builder, and instantly fell in love! I got inspired and wanted to make something similar for AWS DynamoDB.
Thus, I developed Tsynamo! Instead of calling it type-safe, I decided to go with type-friendly, because the library is still in an early stage, and is not 100% type-safe.
Under the hood, Tsynamo compiles the built queries into AWS SDK v3 commands. I feel that Tsynamo simplifies the AWS SDK API quite a lot since the developer doesn't have to mess around with condition/filter expressions or attribute names/values themselves, and as a bonus gets autocompletion for building the queries!
There's also a playground to test it out in your browser: https://try.tsynamo.dev. It might not have the most up-to-date API of the library in use yet, but you can get the library's main idea from there.
Since the project is still in its early stages, it doesn't yet have 100% support for all DynamoDB features, like querying indexes. The next steps will be increasing the support coverage and perhaps adding automatic type generation as inspired by kysely-codegen (https://github.com/RobinBlomberg/kysely-codegen).
Would love to get some feedback, thanks in advance!

Project mention: The New Transparent RPC for JavaScript | dev.to | 2023-10-23

Prim+RPC provides a powerful library for calling functions remotely and remains invisible once it is set up. I can define a function on the server of my choice and call that function on the client, all using JavaScript. Yet requests are simple enough to make outside of JavaScript as well.

Project mention: Struggling to Map ZodEnum to Field Options for Dynamic Form Generation | /r/typescript | 2023-09-29

I'm working on a utility function called createOptions in TypeScript that dynamically maps a Zod schema to options that configure how each schema field should be rendered in a form. This is part of my library, Zod To Fields, which aims to automate your form field generation with type safety. The library effortlessly creates form fields from Zod schemas, ensuring TypeScript type safety and developer-friendly code completion.
