@atscript/moost-validator

Define your models once — get TypeScript types, runtime validation, and DB metadata from a single .as model.

Documentation · Moost Validator Guide

Drop-in Atscript validation for the Moost framework. Automatically validates handler parameters against .as model constraints — no manual validate() calls needed.

Installation

pnpm add @atscript/moost-validator

Peer dependencies: moost, @moostjs/event-http, @atscript/core, @atscript/typescript.

Quick Start

import { Moost } from 'moost'
import { validatorPipe, validationErrorTransform } from '@atscript/moost-validator'

const app = new Moost()
app.applyGlobalPipes(validatorPipe())
app.applyGlobalInterceptors(validationErrorTransform())

Any handler parameter typed with an Atscript-compiled class is now automatically validated. On failure, a 400 Bad Request response is returned with structured error details.

Features

• Automatic validation — runs during the VALIDATE pipeline stage before business logic
• Composable — apply globally or per-controller/handler via @UseValidatorPipe()
• Clean error responses — interceptor converts ValidatorError to HttpError(400)
• Validator options — partial, unknownProps, errorLimit, plugins
• Zero runtime dependencies — everything via peer deps
