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.

6 Reasons why JSON Schema is worth your time
In the JavaScript ecosystem you can use the excellent AJV package to validate any JavaScript object against a JSON schema. This is especially useful to ensure that API contracts are maintained when communicating with other services.

Migrate Your Express Application to Fastify
Since Fastify supports schema validation with Ajv, the validate module is no longer required on the /shorten route, and we can specify the JSON schema directly on the route. The controllers for both routes will largely remain the same, except that the res parameter is renamed to reply as before:

Has anybody used Typia library?
There's a ton of schema validators out there and most devs have their personal favorite. Mine was zod and is now typebox + ajv.

Accept only specific keys in JSON or form-data format in express?

Advanced Fastify: Hooks, Middleware, and Decorators
Fastify uses JSON schema to define the validation rules for each route's input payload, which includes the request body, query string, parameters, and headers. The JSON schema is a standard format for defining the structure and constraints of JSON data, and Fastify uses Ajv, one of the fastest and most efficient JSON schema validators available.

Getting Started with Fastify for Node.js
In Fastify, JSON schema validation is a built-in feature that allows you to validate the payload of incoming requests before the handler function is executed. This ensures that incoming data is in the expected format and meets the required criteria for your business logic. Fastify's JSON schema validation is powered by the Ajv library, a fast and efficient JSON schema validator.

How can we map data from JSON to typescript object efficiently?
I think you're looking for a json schema validator like Ajv or Zod.

5 useful JSON tools to improve your productivity
We can use JSON Schema to validate that our data adheres to a specific structure. Ajv is one popular validator tool for JavaScript applications that allows us to create a schema and then validate JSON against that schema. Here's an example of using Ajv to validate one of the above JSON examples against a schema:

Ask HN: JSON API object type definitions and validation in 2023?
Hey HN,
We're designing a new system and have been kicking the can about JSON object definitions and validation. Soon we need to settle on a system to validate API request bodies and provide helpful error messages.
In the past, I've used JSON Schema ( https://json-schema.org/ ) to define definitions and ajv ( https://ajv.js.org/ ) to validate, but it's a bit verbose and ajv validation errors are more cryptic than I'd like to deal with.
TypeSchema looks interesting. It seems solid (and perhaps stable?), but development hasn't been active for 2 years. It also looks like we'd still need to generate JSON Schema and choose a validation library
Anyway, I'm very curious how others are approaching this problem. How do you organize and generate validations for your type definitions? What libraries do you use to validate and provide human readable error messages?
Thank you!
What are some alternatives?
zod - TypeScript-first schema validation with static type inference
joi - The most powerful data validation library for JS [Moved to: https://github.com/hapijs/joi]
typebox - Json Schema Type Builder with Static Type Resolution for TypeScript
Yup - Dead simple Object schema validation
nestia - Make NestJS much faster and easier
fast-json-stringify - 2x faster than JSON.stringify()
tv4 - Tiny Validator for JSON Schema v4
slow-json-stringify - The slowest stringifier in the known universe. Just kidding, it's the fastest (:
class-validator - Decorator-based property validation for classes.
