ts-sql VS prisma1

There is an implementation of SQL that operates on a table shaped type, entirely at type level. For your amusement: https://github.com/codemix/ts-sql

There are a bunch of more practical takes that codegen types from your database and generate types for your queries, eg: https://github.com/adelsz/pgtyped

To me the second approach seems much more pragmatic because you don’t need to run a SQL parser in a fairly potato interpreter on every build

> If I would level criticisms at dialyzer it would be its sometimes difficult to read warnings, it’s speed (despite being multithreaded) and the race conditions in the VS Code plugin (which is looking for extra maintainers – if I had time I would help).

One of the advantages of TypeScript is that VSCode is written in TypeScript, and both VSCode and TypeScript are developed by the same company, so there's a really nice synergy there. I imagine Kotlin users feel the same way using Jetbrains products, and Swift users feel the same way about XCode.

Dialyzer looks interesting, but I can't imagine giving up on the expressiveness of TypeScript. Some of the things you can do with generics, mapped types, intersection types, template literal types, conditional types, and utility types are almost mind boggling. It's difficult to reap all of the benefits of static analysis without some of these advanced type operators. The type manipulation section of the TS manual is really underrated.

Someone for example wrote an SQL parser in TypeScript that requires no runtime code [1]. It can infer the types of an SQL query's result based on an SQL string without any runtime code execution. There was a similar project where someone built a JSON parser entirely using the type system [2]. There's also an ongoing discussion on Github about the the fact that TypeScript's type system appears to be a Turing-complete language with some other cool examples [3]. My point is that the type system is incredibly expressive. You rarely run into an idiom that can't be typed effectively.

If anyone saw this meme and thought, "damn parsing a type from a SQL query, that looks useful" (as I did), the source appears to be from here.

I mean, why stop there? https://github.com/codemix/ts-sql

Which allows for things like this type that implements a simplified SQL query parser checked against a provided 'database' object:

This project was my go-to "nifty but pointless" example for TS string literal types before this article :)

author of ts-sql[0] here, this looks great (and a way more practical approach!)

I was surprised to see Prisma (a js library) listed, digging more I found out that they indeed had an Scala project which is now archived https://github.com/prisma/prisma1

Hey there, I'm Nikolas from the Prisma team. Just came here to quickly clarify this notion:

> Prisma is an API server that puts a GraphQL API in front of a DB.

Prisma is an ORM which generates a JavaScript/TypeScript client library for your database.

Your description is very true for Prisma 1 (which has been in maintenance mode for several years and is officially deprecated by now [1]), but the latest version(s) of Prisma (v2+) don't expose a GraphQL API any more. Prisma 1 also used GraphQL SDL for data modeling, the Prisma ORM on the other hand has its own, custom modeling language for describing database schemas in a declarative way and also comes with a flexible migration system.

That being said (and as Jens also mentioned elsewhere), the Prisma ORM does use GraphQL _internally_ as a wire protocol. However, as a developer, you _never_ touch this internal GraphQL layer and are not even supposed to be aware of it (you actually have to jump through a lot of hoops to even "find" it). It's also very likely that we'll replace GraphQL as a wire protocol in the future, so "GraphQL" really isn't something you should be thinking about as a developer who is using Prisma.

Hope that clarifies the situation a bit, let me know if you have any further questions around this topic.

Could you clarify this? Are you referring to the old Prisma 1 Cloud or the new Prisma Data Platform?

First released in 2019, Prisma is the newest ORM of the four we discussed. It will need time to get to a more mature state. Recently, the release of version 3 introduced a few breaking changes. There are also some existing issues noted in GitHub, such as that it does not support some Postgres column types.

Mongoose is quite a standard also open-source, but Prisma is an emerging modern solution that seems to take the cake.

Well, here comes Blitz, the agnostic monolith. Take the database, for example - Blitz comes out-of-the-box with Prisma 2. However, you're free to switch to another one like Fauna or DynamoDB. The same goes for the configuration; deciding a folder structure, defining routing conventions, selecting a styling library, and adding authorization and authentication are all set up by default, but that doesn't mean you cannot go your own way.

There is also a RealWorld port (Rakkas implementation of the RealWorld specification), a simple but complete fullstack application demonstrating how to approach building a REST API, accessing your database (via Prisma), handling authentication, testing, and more.

If you're into Typescript and prefer a code-first approach when working with databases, you'll be happy to learn about Prisma! Prisma is a next-generation Node.js and TypeScript ORM, that allows you to define a schema using a dedicated DSL so that you can then have all the comforts of modern development environments like intellisense, static type checking, automatic scaffolding and more.

It is a frontend framework, but with API routes and ORMs like https://www.prisma.io/ , you could use it as a complete stack in traditional sense I suppose.
