Usage

Example AENS Example

const EpochHttpClient = require('aepps-epoch-js')

const aensLifecycle = async (domain, salt) => {

  // External port => 3003
  // Internal port => 3103
  let client = EpochHttpClient('localhost', 3003, 3103)

  let domainData = client.aens.query(domain)
  if (domainData) {
    let nameHash = domainData['name_hash']
    console.log(`Name ${domain} is not available anymore! hash: ${nameHash}`)
  } else {
    // get the commitment hash
    let commitment = await client.aens.getCommitmentHash(domain, salt)
    
    // preclaim the name
    let preclaimHash = await client.aens.preClaim(commitment, 1)
    console.log(`Preclaim hash: ${preclaimHash}`)
    
    // wait for 1 block
    await client.base.waitNBlocks(1)
    
    // Claim the domain
    let nameHash = await client.aens.claim(domain, salt, 1)
    console.log(`Domain claimed with hash ${nameHash}`)
    
    // Let the name point to an account (or oracle)
    let updatedNameHash = await client.aens.update('ak$3Xp...rLYHyuA2', nameHash)
    console.log(`${updatedNameHash} is just the same name hash`)
    
    let updatedDomainData = client.aens.query('example.aet')
    console.log(`Domain now points to ${JSON.parse(updatedDomainData['pointer'])['account_key']}`)
    
    // Revoke the domain
    await client.aens.revoke(nameHash, 1)
    return nameHash
  }
}

// salt should be random integer
let randomInt = Math.floor(Math.random() * Math.floor(Number.MAX_SAFE_INTEGER))
aensLifecycle('aepps.aet', 12345).then((nameHash) => console.log("Life and death of 'aepps.aet'"))
