@marmeon/validation

The validation rules of Marmeon apps — r.string(), r.integer(), r.email(), r.object(), .unique() and the rest — typed from end to end, with messages in the request's language, for request bodies, queries and job payloads.

Installation

Part of every new Marmeon app: pnpm create marmeon installs it.

Its engine, Valibot, is a dependency of this package and never re-exported: apps validate with rules. The rules are Standard Schema objects, so a schema of another library works where the framework takes one.

A request

import { defineRequest } from '@marmeon/http';
import { rules as r } from '@marmeon/validation';

export const StoreNoteRequest = defineRequest({
  schema: r.object({ title: r.string().trim().required().max(200) }),
});

A controller with static request = StoreNoteRequest gets ctx.body typed as { title: string }, trimmed and checked. A form that fails gets its errors back, in the visitor's language.
