Validity

The validity module provides utility functions for validating various types of data in the application.

Import

import { isLinkValid, isValidEnsName } from 'ethereum-identity-kit'
 
// For server side usage
import { isLinkValid, isValidEnsName } from 'ethereum-identity-kit/utils'

Functions

isLinkValid

Checks if a given link is a valid http or https link, or is pulling from public or assets folders. This is used to filter out ipfs or invalid links and fall back to the ENS Metadata Service (if there is an ENS name).

const isValid = isLinkValid('https://example.com') // true
const isValid = isLinkValid('invalid-link') // false

Parameters

Return Value

Returns true if the link contains one of the following prefixes:

• https://
• http://
• public/
• /assets

Returns false if the link is undefined or doesn’t contain any of the valid prefixes.

isValidEnsName

Validates if a given string is a valid ENS (Ethereum Name Service) name.

const isValid = isValidEnsName('vitalik.eth') // true
const isValid = isValidEnsName('invalid-ens') // false

Parameters

Return Value

Returns true if the name is a valid ENS name, false otherwise. Uses the normalize function from viem/ens for validation.
