Valibotx NPM | npm.io

valibotx

A collection of extensions for valibot.

valibot maintainers tend to keep the valibot core to the minimum and sometimes refuse to accept non-essential contributions, as explained here.

valibotx re-exports valibot and adds a set of non-obtrusive extensions. Due to how valibot is organized, this is still perfectly tree-shakeable.

valibot <0.31: valibotx 1
valibot >=0.31: valibotx 2

Install

npm install valibot valibotx

Use

Simply import valibotx instead of valibot and enjoy both the original and the new methods:

import * as v from "valibotx"

const integerSchema = v.integerNumber([v.minValue(100)])

Schemas

`integerNumber`

Validate integer number.

`naturalNumber`

Validate natural number (positive integer).

Parse data

`safeParseOutput`

Shortcut for safeParse().output. Returns undefined for failed parse.

Alias: tryParse.

Methods

`coerceArray`

Coerces the input to be an array.

Useful for normalizing query string inputs such as ?id=1&id=2 which are presented as string | string[].

Usage:

// works for both single ID and multiple IDs
const ids = v.parse(v.coerceArray(v.array(v.string())), request.query.id)

Issues

`createFlatErrors`

Utility shortcut to simplify creating FlatErrors:

accepts root error(s), nested error(s), or both
converts single strings to error lists

Usage:

createFlatErrors("Single root error")
// => FlatErrors { root: ["Single root error"], nested: {} }

createFlatErrors(["Root error 1", "Root error 2"])
// => FlatErrors { root: ["Root error 1", "Root error 2"], nested: {} }

createFlatErrors({ nested1: "Nested 1", nested2: ["Nested 2a", "Nested 2b"] })
// => FlatErrors { nested: { nested1: ["Nested 1"], nested2: ["Nested 2a", "Nested 2b"] } }

createFlatErrors("Root", { nested: "Nested" })
// => FlatErrors { root: ["Root"], nested: { nested: ["Nested"] } }
