// RUNTIME VALIDATORS
export function is<T>(input: unknown | T): input is T; // returns boolean
export function assert<T>(input: unknown | T): T; // throws TypeGuardError
export function validate<T>(input: unknown | T): IValidation<T>; // detailed

// STRICT VALIDATORS
export function equals<T>(input: unknown | T): input is T;
export function assertEquals<T>(input: unknown | T): T;
export function validateEquals<T>(input: unknown | T): IValidation<T>;

// JSON
export function application<T>(): IJsonApplication; // JSON schema
export function assertParse<T>(input: string): T; // type safe parser
export function assertStringify<T>(input: T): string; // safe and faster

Typia is a transformer library of TypeScript, supporting below features:

• Super-fast Runtime Validators
• Safe JSON parse and fast stringify functions
• JSON schema generator

All functions in typia require only one line. You don't need any extra dedication like JSON schema definitions or decorator function calls. Just call typia function with only one line like typia.assert<T>(input).

Also, as typia performs AOT (Ahead of Time) compilation skill, its performance is much faster than other competitive libaries. For an example, when comparing validate function is() with other competitive libraries, typia is maximum 15,000x times faster than class-validator.

Nestia is a set of helper libraries for NestJS, supporting below features:

• @nestia/core: 15,000x times faster validation decorators
• @nestia/sdk: evolved SDK and Swagger generators
  • SDK (Software Development Kit)
    • interaction library for client developers
    • almost same with tRPC
• nestia: just CLI (command line interface) tool

Reactia is an automatic React components generator, just by analyzing TypeScript type.

• @reactia/core: Core Library analyzing TypeScript type
• @reactia/mui: Material UI Theme for core and nest
• @reactia/nest: Automatic Frontend Application Builder for NestJS

When you want to automate an individual component, just use @reactia/core.

import ReactDOM from "react-dom";

import typia from "typia";
import { ReactiaComponent } from "@reactia/core";
import { MuiInputTheme } from "@reactia/mui";

const RequestInput = ReactiaComponent<IRequestDto>(MuiInputTheme());
const input: IRequestDto = { ... };

ReactDOM.render(
    <RequestInput input={input} />,
    document.body
);

Otherwise, you can fully automate frontend application development through @reactia/nest.

import React from "react";
import ReactDOM from "react-dom";

import { ISwagger } "@nestia/swagger";
import { MuiApplicationTheme } from "@reactia/mui";
import { ReactiaApplication } from "@reactia/nest";

// swagger.json must be generated by @nestia/sdk
const swagger: ISwagger = await import("./swagger.json");
const App: React.FC = ReactiaApplication(MuiApplicationTheme())(swagger);

ReactDOM.render(
    <App />,
    document.body
);
