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.
ts-runtime
- Why TS type guard for interfaces uses strings instead of implementing something better?
-
SafeScript runtime tool that add checks for JavaScript and TypeScript
There is also https://github.com/fabiandev/ts-runtime for Typescript that looks more polished. Too bad both these projects were abandoned, it would be such a cleaner alternative to libraries like io-ts.
-
TypeScript runtime type-checking - designed for simple use, through to enforcing API payload schema
I like io-ts though it has bad documentation. More random examples are ts-runtime and ajv. JS examples are joi, v8n, validate.js.

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?
ajv - The fastest JSON schema Validator. Supports JSON Schema draft-04/06/07/2019-09/2020-12 and JSON Type Definition (RFC8927)
zod - TypeScript-first schema validation with static type inference
typescript-is
class-validator - Decorator-based property validation for classes.
you-are-not - A minimal, blazing fast, TypeScript runtime type-checker. It is intuitive, API-centric, and customisable. A must-have for API payload sanitiser, type-checking, validation, error handing and messaging helper -- all in a small and neat pack. [Moved to: https://github.com/calvintwr/not]
openapi-generator - OpenAPI Generator allows generation of API client libraries (SDK generation), server stubs, documentation and configuration automatically given an OpenAPI Spec (v2, v3)
ts-runtime-checks - A typescript transformer that automatically generates validation code from your types.
fp-ts - Functional programming in TypeScript
cardboard-js - A very simple, yet powerful reactive framework, to create web applications. All of this with, no HTML, CSS, JSX, and no required build.
runtypes - Runtime validation for static types
SafeScript - This package intent is to make "safe" JavaScript runtime by checking types at runtime and disallowing most of implicit coercion
joi - The most powerful data validation library for JS [Moved to: https://github.com/hapijs/joi]
