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.
- Executable Playground of "typia", super-easy/fast TypeScript validator/serializer

[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.

[Typia] I made realtime demo site of 20,000x faster validation (+200x faster JSON stringify)

Typing for JSON Payloads
I'll throw https://github.com/woutervh-/typescript-is in the mix as well.

Handling json input in an express app
I'm a fan of typescript-is. Provides both compile time and run time validations

What can I *use* Rust for?
For what it's worth, thanks to TypeScript transformers (a feature baked into the compiler), one can create a transformer library that verifies an object is valid for any TypeScript type and conveys that information to the typechecker. And indeed, it's already been made. It allows to parse unknown into a given T. This is nice, because one can generate a JSON schema out of a TS type, for other languages/codebases to integrate safely.
-
Do you use code generators? If so, which ones?
But to make it worth the comment, I’ll point people to typescript-is which uses transformations at compile-time to generate run-time type checking code.
-
TypeScript runtime type-checking - designed for simple use, through to enforcing API payload schema
Then there's also typescript-is, which is pretty neat because it converts actual compile-time type definitions to runtime type checks, so it doesn't require changing the type definitions.
-
JSON Schema === Runtime Type System for TypeScript
typescript-is. This uses a compile-time transformer to generate code for type-checking. You'll need to use ttypescript instead of typescript to compile your code (I recommend setting this up with ts-patch). It won't work if your build pipeline is actually using something like esbuild or Babel to transpile TS->JS.

How an Anti-TypeScript “JavaScript developer” like me became a TypeScript fan
If you're not using a bunch of generics, check out typescript-is [1]. It takes little work to get it setup, but it generates run time type checks for you. I understand why typescript decided to not add this functionality to the core of the language, but it's starting to feel like the largest missing piece of typescript is a built-in way to generate run-time type-checks for user-defined types from just the type definition.
The happy medium we've found with that module is using the runtime type-check on anything "unsafe" to bless the result using typescript-is's equals functionality, but still allowing programmers to use casting with a comment justifying its necessity. For us our list of unsafe is results pulled from the db, anything parsed from JSON, and incoming request bodies (which can be a special case of parsing from JSON, but not always).
