Adria

A super simple library for parsing form data and search params. It makes it easy to narrow the type and convert the input to something useful before doing the validation.

npm i adria-parser
yarn add adria-parser
pnpm add adria-parser

Overview

import { parse } from "adria-parser";

const formData = new FormData();

// intellisense
const { username, age, profile_image, birthday interests } = parse(formData, {
  username: "string",
  age: "number",
  profile_image: "file",
  birthday: "date",
  interests: "array.string",
});

// null if empty or can't be converted to defined type

// username: string | null
// age: number | null
// profile_image: File | null
// birthday: Date | null
// interests: string[]

Reference

const parse: (
  input: FormData | URLSearchParams,
  schema: Record<string, InputType>
) => Record<string, any>;

The result will be a FieldName:DefinedType | null record, where it's null if the field didn't exist or it couldn't coerce the input to the defined type.

InputType

• PrimitiveType
• ${CompoundType}.${PrimitiveType}

PrimitiveType

• string => string
• number => number
• boolean => boolean
• date => Date
• file => File

CompoundType

• array => T[]
