buildTransaction

The buildTransaction method is useful when you need to build a contract's Transaction body, mainly when you want to make multiple contract calls. E.g.:

import { buildTransaction } from '@wpdas/naxios'
import { contractApi } from './web3Api'

// Using the default instance's contract
const transactionA = buildTransaction('set_greeting', { args: { greeting: 'Hello my dear!' } })
const transactionB = buildTransaction('set_age', { args: { age: 22 } })
// Using diff contract
const transactionC = buildTransaction('update_state', {
  receiverId: 'my-state-contract.testnet',
  args: { allowed: true },
})

// Optional
const callbackUrl = 'https://my-page.com/callback-success'

// [payable]
contractApi.callMultiple([transactionA, transactionB, transactionC], callbackUrl).then(() => console.log('Done!'))

validateNearAddress

This is used to check if an address is a valid NEAR address.

import { validateNearAddress } from '@wpdas/naxios'

console.log(validateNearAddress('fake.near')) // true
console.log(validateNearAddress('fake.nears')) // false
console.log(validateNearAddress('fake.testnet')) // true
console.log(validateNearAddress('fake')) // false

calculateDepositByDataSize

Calculate required deposit for data being stored. (~0.00001N per byte) with a bit extra for buffer.

import { calculateDepositByDataSize } from '@wpdas/naxios'

const myData = { age: 22, name: 'user name' }
console.log(calculateDepositByDataSize(myData)) // 0.00087 Near (not yocto NEAR)
