Imports

Imports

All contracts and models must explicitly import features of the NEAR they intend to use. Not all of these features are used all of the time of course.

import {
  context, // visibility into account, contract and blockchain details
  logging, // append to the execution environment log (appears in JS Developer Console when using near-api-js)
  storage, // key-value store for the contract (used by PersistentMap, PersistentVector and PersistentDeque)
  PersistentMap, // data structure that wraps storage to appear like a Map
  PersistentVector, // data structure that wraps storage to appear like a Vector
  PersistentDeque, // data structure that wraps storage to appear like a Deque
  PersistentSet, // data structure that wraps storage to appear like a Set
  ContractPromise, // make asynchronous calls to other contracts and receive callbacks
  base58, // utility base58 encoder
  base64, // utility base64 encoder / decoder
  math, // utility math functions for hashing using SHA and Keccak as well as pseudo-random data
  utils, // utility type conversion and read_register
