Typia

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

// JSON FUNCTIONS
export namespace 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
}

// PROTOCOL BUFFER
export namespace protobuf {
    export function message<T>(): string; // Protocol Buffer message
    export function assertDecode<T>(buffer: Uint8Array): T; // safe decoder
    export function assertEncode<T>(input: T): Uint8Array; // safe encoder
}

// RANDOM GENERATOR
export function random<T>(g?: Partial<IRandomGenerator>): T;

Typia is a transformer library supporting below features:

Super-fast Runtime Validators
Enhanced JSON functions
Protocol Buffer encoder and decoder
Random data generator

Note

Only one line required, with pure TypeScript type

Runtime validator is 20,000x faster than class-validator

JSON serialization is 200x faster than class-transformer
