海外TECH	DEV Community	[Typia] 15,000x faster validator and its histories	https://dev.to/samchon/typia-15000x-faster-validator-and-its-histories-1fmg	Typia x faster validator and its histories Series of TypeScript Compiler based LibrariesI made x faster TypeScript validator libraryI found x faster TypeScript Validator Library Typia x faster validator and its historiesI made x faster JSON stringify functions even type safeNestia super fast validator decorators for NestJSAutomatic React components generator from TypeScript type Renamed to TypiaHello I m developer of typescript json typia In nowadays I ve renamed typescript json library to typia because the word JSON no more can represent it Key feature of typia had been changed from faster JSON stringify function to superfast validation function Furthermore typia has started supporting Protocol Buffer in alpha version not regular feature yet Introducing such package renaming from typescript json to typia I will tell you which changes had been occured during six months Lots of interesting features and improvements have been happened What typia is RUNTIME VALIDATORSexport function is lt T gt input unknown T input is T returns

isStringify validateStringifytypia is a transformer library of TypeScript supporting below features Super fast Runtime ValidatorsSafe JSON parse and fast stringify functionsJSON schema generatorAll 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 lt T gt 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 x times faster than class validator Became x faster runtime validator library TypeBox was faster than Typia in here ObjectSimple caseexport type ObjectSimple ObjectSimple IBoxD export namespace ObjectSimple export interface IBoxD scale IPointD position IPointD rotate IPointD pivot IPointD export interface IPointD x number y number z number Do you remember About a month ago I wrote an article about TypeBox and said I found faster vlidator library than me in some cases During a month I d tried to understand and study the reason why During the studies I found the reason why The secret was on inlining When validating an instance type typia generates functions per object type Therefore when a type is related with object types internal functions would be generated However typebox let user to decide whether to make validate function for an object type or not by recursiveRef flag Benchmark code about typebox was written by typebox author himself Looking at below code you may understand what the inlining means and how typia and typebox are different typia is generating functions per object type BoxD and Pointd but typebox does not make any internal function but inline all of them COMPILED VALIDATION CODE OF TYPIAconst is input gt const io input gt object typeof input scale amp amp null input scale amp amp io input scale amp amp object

amp amp typeof value pivot z number amp amp isNaN value pivot z As you know function calls have their own cost Therefore inlining may be faster than function call However inlining is not always faster then function call and there is a section where performance is reversed between function calls and inlining typebox let users to determine by themselves through JSON schema definition but typia can t do it because typia generates runtime validator function automatically by only one line statement typia assert lt T gt input CODE OF TYPIAimport typia from typia typia is lt ObjectSimple gt input CODE OF TYPEBOXimport Type from sinclair typebox import TypeCompiler from sinclair typebox compiler const PointD Type Object x Type Number y Type Number z Type Number const BoxD Type Object scale PointD position PointD rotate PointD pivot PointD TypeBoxObjectSimple TypeCompiler Compile BoxD TypeBoxObjectSimple Check input Therefore it is necessary for me to compare the pros and cons of function call and inlining and to select an algorithm at an appropriate level I d changed typia code to use such inlining skill in special cases and the result was typia became x faster validator than class validator From now on typia is the fastest runtime validator library Measured on Intel i g Surface Pro New Features More Types REST ARRAY TYPE IN TUPLE TYPEtype RestArrayInTuple boolean number string

string amp gt After introducing typia typescript json at that time many dev to users maybe started using it and wrote lots issues for bug reportings or new feature suggestions too Resolving issues for six months typia became much stronger for TypeScript types For six months of improvements typia could support template literal types and built in class types like UintArray Sometimes bug from horrible types like Array rest parametrized tuple type or endless recursive and conditional types had been reported Anyway I d enhanced and resolved all of those issues and now I say that typia supports every TypeScript type with confidence Of course the word every TypeScript type could be broken in any time but it is not now maybe Comment TagsSome users requested typia to support much more types even TypeScript does not support To response to their inspirations I d studied solution for a while and found a good way at the right time It is extending typia s spec through comment tags For an example JavaScript does not support integer type but typia can validate the integer type through type int comment tag Below is an example using such comment tags Although those comment tags are written as a comment but they re compile time safe If wrong grammered comment tags being used typia will generate compilation error therefore no need to worry about runtime error by mistakes export interface TagExample ARRAYS You can limit array length like below minItems maxItems Also you can use items tag instead items gt lt length lt items gt lt length items gt length lt Furthermore you can use additional tags for each item type uint format uuid array Array lt string number gt If two dimensional array comes length limit would work for both st and nd level arrays Also using additional tags for each item string would still work items format url matrix string NUMBERS Type of number It must be one of integer or unsigned integer type int type uint type number You can limit range of numeric value like below minimum maximum Also you can use range tag instead range gt lt x lt range gt lt x range gt x lt range number Step tag requires minimum or exclusiveMinimum tag step exclusiveMinimum range step number Value must be multiple of the given number multipleOf multipleOf number STRINGS You can limit string length like below minLength maxLength Also you can use length tag instead length gt length length gt lt length amp amp length lt length gt lt length amp amp length lt length gt lt length length gt length lt length string Mobile number composed by only numbers Note that typia does not support flag of regex because JSON schema definition does not support it either Therefore write regex pattern without characters and flag pattern gt RegExp test mobile string E mail address format

lt T gt input T IValidation lt UintArray gt In nowadays I am developing Protocol Buffer features ThoseT features are not published as stable version yet but you can experience them through dev version Also you can read detailed manual about those Protocol Buffer features in Guide Documents Protocol Buffer of typia console log typia message lt ObjectSimple gt syntax proto message ObjectSimple message IBoxD ObjectSimple IPointD scale ObjectSimple IPointD position ObjectSimple IPointD rotate ObjectSimple IPointD pivot message IPointD double x double y double z Those features are suggested by my neighbor TypeScript backend developer who is suffering from Protocol Buffer development Although there re some libraries supporting Protocol Buffer in TypeScript but they re not so convenient Therefore he suggested them hoping to implement Protocol Buffer features very easily like other typia functions can be done with only one line Listening his opinion and sympathizing with necessity and it seems to make typia more famous I ve accepted his suggestion Just wait a month then you TypeScript developers can implement Protocol Buffer data very easily than any other language Also let s make typia more famous Nestia boosted up validation decoratorNestia is a helper library set for NestJS supporting below features nestia core x times faster validation decorator using typia nestia sdk evolved SDK and Swagger generator for nestia corenestia just CLI command line interface toolDeveloping typia and measuring performance benchmark with other competitive validator libraries I ve known that class validator is the slowest one and its validation speed is maximum x times slower than mine typia However NestJS the most famous backend framework in TypeScript is using the slowest class validator Therefore some TypeScript developers have identified that they re using such slowest validator on their backend system by my previous dev to article and requested me to support new validation decorator for NestJS In response to their desire I ve made a new library nestia core It provides x faster validation decorator than ordinary NestJS validator decorator using class validator

validator Promise lt IBbsArticle gt However as NestJS can generate swagger documents only when using the slowest class validator decorator I had to make a new program nestia sdk which can generate swagger documents from nestia core decorator For reference nestia sdk also can generate SDK Software Development Kit library for client developers by analyzing backend server codes in the compliation level If I write next article in here dev to subject of the new article would be this nestia and SDK library In fact I had developed nestia for a long time However previous nestia had focused only on SDK library generation Before typia there had not been any consideration about developing faster validation decorator Therefore only nestia core is the new library made by requirements from TypeScript backend developers nestia sdk is just a little bit evolved version of previous nestia to support nestia core SDK library generated by nestia sdkimport Fetcher IConnection from nestia fetcher import
