Initializing Contracts with near-shell

When setting up the contract creating the contract account, deploying the binary, and initializing the state must all be done as an atomic step. For example, in our tests for the lockup contract we initialize it like this:

pub fn init_lockup(
        &self,
        runtime: &mut RuntimeStandalone,
        args: &InitLockupArgs,
        amount: Balance,
    ) -> TxResult {
        let tx = self
            .new_tx(runtime, LOCKUP_ACCOUNT_ID.into())
            .create_account()
            .transfer(ntoy(35) + amount)
            .deploy_contract(LOCKUP_WASM_BYTES.to_vec())
            .function_call(
                "new".into(),
                serde_json::to_vec(args).unwrap(),
                200000000000000,
                0,
            )
            .sign(&self.signer);
        let res = runtime.resolve_tx(tx).unwrap();
        runtime.process_all().unwrap();
        outcome_into_result(res)
    }

To do this with near shell, first add a script like deploy.js:

const fs = require('fs');
const account = await near.account("foundation");
const contractName = "lockup-owner-id";
const newArgs = {
  "lockup_duration": "31536000000000000",
  "lockup_start_information": {
    "TransfersDisabled": {
        "transfer_poll_account_id": "transfers-poll"
    }
  },
  "vesting_schedule": {
    "start_timestamp": "1535760000000000000",
    "cliff_timestamp": "1567296000000000000",
    "end_timestamp": "1661990400000000000"
  },
  "staking_pool_whitelist_account_id": "staking-pool-whitelist",
  "initial_owners_main_public_key": "KuTCtARNzxZQ3YvXDeLjx83FDqxv2SdQTSbiq876zR7",
  "foundation_account_id": "near"
}
const result = account.signAndSendTransaction(
    contractName,
    [
        nearAPI.transactions.createAccount(),
        nearAPI.transactions.transfer("100000000000000000000000000"),
        nearAPI.transactions.deployContract(fs.readFileSync("res/lockup_contract.wasm")),
        nearAPI.transactions.functionCall("new", Buffer.from(JSON.stringify(newArgs)), 100000000000000, "0"),
    ]);

Then use the near repl command. Once at the command prompt, load the script:

> .load deploy.js

Note: nearAPI and near are both preloaded to the repl's context.
