joi-multiaddr

Validate a multiaddr and common formats.

Install

npm install joi-multiaddr

Usage

const Joi = require('joi').extend(require('joi-multiaddr'))

/**
 * Validate a String or Buffer is in multiaddr format:
 */

const schema = Joi.multiaddr()
const result = schema.validate('/ip4/0.0.7.6/tcp/1234')

console.log(result.error) // null
// Note, successful validation converts to a Multiaddr instance:
console.log(result.value) // <Multiaddr 04000007060604d2 - /ip4/0.0.7.6/tcp/1234>

/**
 * Validate formats using mafmt (https://github.com/multiformats/js-mafmt):
 */

const dnsSchema = Joi.multiaddr().DNS()
const tcpSchema = Joi.multiaddr().TCP()
const ipfsSchema = Joi.multiaddr().IPFS()
/* etc. */

ipfsSchema.validate('/ipfs/QmcgpsyWgH8Y8ajJz1Cu72KnS5uo2Aa2LpzU7kinSoooo4') // Success!
ipfsSchema.validate('/ip4/0.0.7.6/tcp/1234') // Failure :(
