A minimally flexible data validator

Features:

• Props are required by default
• Strict by default (no type cohersion)
• No unknown properties allowed

Example

import { boolean, number, object, string } from 'betterbe'

const validateUid = string({
  minLength: 10,
  maxLength: 12,
  alphabet: '0123456789',
})

const validateMessage = object({
  from: object({
    uid: validateUid,
  }),
  message: string({ minLength: 1, maxLength: 280 }),
  utcTime: number({ integer: true }),
  urgent: boolean({ required: false }),
})

// This is not expected to throw (valid input)
validateMessage.validate({
  from: { uid: '1234567890' },
  message: 'Hello, World!',
  utcTime: 1630000000,
})

// This is expected to throw as character `-` is not valid in the uid alphabet
validateMessage.validate({
  from: { uid: '1234567-90' },
  message: 'Hello, World!',
  utcTime: 1630000000,
})
