Stars - the number of stars that a project has on GitHub. Growth - month over month growth in stars.
Activity is a relative number indicating how actively a project is being developed. Recent commits have higher weight than older ones.
For example, an activity of 9.0 indicates that a project is amongst the top 10% of the most actively developed projects that we are tracking.

I made Swagger/OpenAPI type definitions and converter library
However, lacking of typia and nestia libraries is obvious. If you also need detailed Swagger/OpenAPI spec like me, but you need more detailed types/properties, or found something missed, please take a contribution.

[Typia] I made Protocol Buffer library of TypeScript, easiest in the world
Therefore, I've implemented the Protocol Buffer features for two months, and introduce you. From now on, you can easily use Protocol Buffer features in typia, with pure TypeScript type. You no more need to define extra schema even including *.proto file. typia will do everything for you. It will analyze your TypeScript type, and generate Protocol Buffer schema and de/serializers automatically.
- Good replacements for Zod, preferably with a similar API/interface?

Secret of Typia, how it could be 20,000x faster validator - Hidden Class Optimization of v8 engine
I've written some articles introducing my TypeScript runtime validator library typia in here dev.to community. In these previous articles, I had often explained that typia boosts up validation spped through AoT (Ahead of Time) compliation, and it is maximum 20,000x faster than class-validator.

Good bye "typescript-is" (ancestor of "typia", 20,000x faster validator)

Migration tool from Swagger to NestJS - SDK generator and Mockup simulator for every backend stacks
If you see actual Mockup Simulator code, then you may exactly understand what it is. Yes, the Mockup Simulator, it's just an internal function returning random data with same type of API interface. For reference, mockup data generation is being done by typia.random() function, which can analyze TypeScript type and generate optimal random generation code in the compliation level.

I've made playground demo of typia - 20,000x faster validator
typia is a super-easy and fast runtime validator library, which needs TypeScript type only. It does not need extra schema definition like ajv or class-validator. It can analyze TypeScript by itself, and generates optmial validation code for each type.

TDD
Qué rico. Si tenés chance meté un proceso de code review fuerte, y para el tema de I/O probá a usar https://github.com/Effect-TS/schema ó https://github.com/gcanti/io-ts que les da una solución obvia al tema de "tipos para lo que devuelva el backend", aunque es en realidad mucho más capaz que eso.

Domain modelling with State Machines and TypeScript by Carlton Upperdine
My fave is still io-ts (https://github.com/gcanti/io-ts/blob/master/docs/index.md) as I find it more flexible than zod at the ingress. The author is also working on the Effect ecosystem which also looks interesting.

Why I Like Using Maps (and WeakMaps) for Handling DOM Nodes
I’ve been using io-ts for this and been very happy with it. [1] It’s similar to Swift’s Coding protocol in case you’re familiar.

Can someone recommend a library for data parsing similar to Zod, but with better support for input transformations/preprocessing?
Yeah, there are a few new concepts and it's not the easiest to pick up right away. The best introduction is here on the main documentation page.
- libraries you are happy that you discovered them
- Is React for small projects an Overkill?
-
how to strictly type this?
We use https://github.com/gcanti/io-ts/blob/master/Decoder.md which has a very similar interface. It can even be used to mutate the data using https://github.com/gcanti/io-ts/blob/master/Decoder.md#the-parse-combinator.

Typescript advanced bits: function overloading, never and unknown types
A good way to significantly improve the reliability of your app is via improving type-safety by moving away from using any to unknown. One relevant example could be when you type your backend responses and when stringifying JSON to using unknown combined with some sort of runtime type checking. It can be done either by using built-in functionality like type guards or using an external library like io-ts, zod or yup.

I found 10,000x faster TypeScript validator library
Usage of TypeBox is similar with io-ts and zod, but it is much powerful and faster than them. Also, TypeBox can generate JSON schema very easily. Therefore, if you're looking for a validator library for new project and not suffering from legacy codes, I think TypeBox would be much better choice than io-ts and zod. TypeBox can totally replace them.

Validate your data with Zod
This check can be done with different libraries like: io-ts, typebox, or zod. These libraries allow you to create objects that represent your typescript definitions. Then, these objects can be used at runtime to validate the received data, in addition, you can also convert this object to a Typescript definition to have all the benefits of using typescript. These objects can be called schema validations because they are responsible for the data validation.
What are some alternatives?
zod - TypeScript-first schema validation with static type inference
typebox - Json Schema Type Builder with Static Type Resolution for TypeScript
class-validator - Decorator-based property validation for classes.
ajv - The fastest JSON schema Validator. Supports JSON Schema draft-04/06/07/2019-09/2020-12 and JSON Type Definition (RFC8927)
openapi-generator - OpenAPI Generator allows generation of API client libraries (SDK generation), server stubs, documentation and configuration automatically given an OpenAPI Spec (v2, v3)
nestia - Make NestJS much faster and easier
runtypes - Runtime validation for static types
fast-json-stringify - 2x faster than JSON.stringify()
fp-ts - Functional programming in TypeScript
slow-json-stringify - The slowest stringifier in the known universe. Just kidding, it's the fastest (:
joi - The most powerful data validation library for JS [Moved to: https://github.com/hapijs/joi]
