SQL databases provide us with many benefits, the most important of which is strong schema enforcement. Yes, you pay the cost of migration when the schema changes, but the gain is far more significant - your code is clean because it can assume all data are in correct shapes.

However, once in a while, we want to break free from such strong guarantees for valid reasons. You may have some tiny objects that you want to attach to the main entities (e.g., metadata of an image) without formalizing them into a separate table. Or you need to store records with many possible sparse fields but want to avoid creating wide tables.

React Table, or more precisely, TanStack Table is a headless table UI library. If you're new to this kind of product, you'll probably ask, "What the heck is headless UI"? Isn't UI all about the head, after all? It all starts to make sense until you try something like React Table.

After polishing ZenStack V2 in the future branch for more than two months, we are happy to make it official now. I would like to take this opportunity to briefly show you the main features of V2 and the stories behind it.

Building a customer-facing application is exciting. But it's not much fun when it comes to the admin console part. However, almost every serious app requires some sort of admin console for operation needs. It doesn't need to be slick in design or have blazing-fast performance. The main focus should be reliability, cost-effectiveness, and extensibility.

There are many different types of admin consoles. In this post, we'll discuss the most common ones: those that allow non-technical people to make changes to the database and ensure proper permission management at the same time.

Authorization is a special topic for software development. You'll get many theories about different patterns if you do a search: their pros and cons. However, it's surprisingly difficult to find concrete examples to follow. It's mainly because the detailed approach highly depends on your specific application: its domain models, unique security requirements, and its choice of framework.

This post aims to fill the gap by targeting Prisma - the most popular ORM for TypeScript developers. By narrowing it down to a specific toolkit and language, we can explain the concepts more efficiently using code instead of words.

EDIT 4/25/2024: the feature has been released in ZenStack V2.

Prisma is a beloved ORM for NodeJS developers. As with every popular open-source project, it has a long wishlist. Here are two prominent examples:

• Support for a Union type #2505
• Support for Polymorphic Associations #1644

They are about the same thing and have received at least 1000 reactions in total. The ask is for modeling an inheritance hierarchy in the database. ORM’s responsibility is to fix the gap between the two world views: "table + relations" and "object-oriented". Polymorphism is an obvious missing piece in its mission.

Prisma is one of the most popular ORMs in the NodeJS world - loved by many for its intuitive data modeling and flexible query APIs. It shines for its concise and powerful syntax for querying relational data, and one great feature of it is to precisely infer the types of query results. Here's an example:

// `todos` is typed as `(Todo & { owner: User })[]`
const todos = await prisma.todo.findMany({
  where: { published: true },
  include: { owner: true }
});

TanStack Query (previously named react-query) is a widely used frontend data query library that greatly simplifies how we fetch, cache, and bind data when working with APIs. It also has excellent TypeScript support, allowing you to build fully typed data query hooks. Prisma and TanStack Query are frequently used together in a full-stack application.

For TypeScript lovers, Prisma has been the perfect solution for building database-centric applications for quite a while. But recently, a new challenger has emerged. If you've been closely tracking the ORM space, you've probably heard of Drizzle, a new ORM being popularized by its flexibility, performance and better user experience. In this article, I'll quest for a comparison. Following the "Show, Don't Tell" mantra, I'll achieve it by building the same API twice, with Drizzle and Prisma, respectively.

NestJS is a great framework. It's versatile, rock solid, and thoroughly documented. You can build pretty much any backend with it: RESTful, GraphQL, WebSocket, Microservice, etc. Among everything, building APIs above databases is still one of the top tasks of backend developers. With the rise of Prisma ORM, more and more people are pairing it with NestJS to get the job done - more efficiently and pleasantly, thanks to Prisma's superb DX.

You can't miss this article if that's the combo you're using or plan to use. I'll demonstrate three approaches to building a secure RESTful API, starting with the most traditional one, and then progressively show how to reduce the amount of code we write and achieve a better result.

Yes, authorization. It's like the "salad part" of your diet - you know it's vital and indispensable but struggle to enjoy. Implementing authorization doesn't need to be a fancy job. Just roll up your sleeves and turn business rules into code. We've all been there at some point and all been hurt by the consequences:

• What will be broken if I move this check to a different place?
• Where's the best place to stuff in this new piece of rule?
• We need to add a new resource type. How can it inherit the existing rules?
