NEAR TransactionManager
This library is a utility for creating, signing, and sending transactions. Currently it is a wrapper around near-api-js.
See the docs: https://near-transaction-manager.netlify.app/
Getting Started
- install the library from npm:
npm i near-transaction-manager - create a
TransactionManagerinstance:
// create a TransactionManager from a NEAR WalletConnection
const transactionManager = TransactionManager.fromWallet(wallet);or
const keyStore = new keyStores.UnencryptedFileSystemKeyStore(credentialsPath);
const transactionManager = new TransactionManager({
transactionCreator: new KeyStoreTransactionCreator({
keyStore,
signerId: wallet.getAccountId(),
networkId: "testnet",
nodeUrl: "https://rpc.testnet.near.org",
}),
transactionSigner: new KeyStoreTransactionSigner({
keyStore,
signerId: wallet.getAccountId(),
networkId: "testnet",
}),
transactionSender: new ProviderTransactionSender({
provider: new JsonRpcProvider("https://rpc.testnet.near.org"),
}),
});- use the
createTransaction,createSignedTransaction,signAndSendTransaction, andsignAndSendTransactionsmethods:
// create a transaction
const transaction = await transactionManager.createTransaction({
receiverId: "example.testnet",
actions: [functionCall("method", {}, DEFAULT_FUNCTION_CALL_GAS, [])],
});
// create a signed transaction
const signedTransaction = await transactionManager.createSignedTransaction({
receiverId: "example.testnet",
actions: [functionCall("method", {}, DEFAULT_FUNCTION_CALL_GAS, [])],
});
// create, sign, and send a transaction
const outcome = await transactionManager.signAndSendTransaction({
receiverId: "example.testnet",
actions: [functionCall("method", {}, DEFAULT_FUNCTION_CALL_GAS, [])],
});
// create, sign, and send many transactions
const outcomes = await transactionManager.signAndSendTransactions([
{
receiverId: "example.testnet",
actions: [functionCall("method1", {}, DEFAULT_FUNCTION_CALL_GAS, [])],
},
{
receiverId: "example.testnet",
actions: [functionCall("method2", {}, DEFAULT_FUNCTION_CALL_GAS, [])],
},
{
receiverId: "example.testnet",
actions: [functionCall("method3", {}, DEFAULT_FUNCTION_CALL_GAS, [])],
},
{
receiverId: "example.testnet",
actions: [functionCall("method4", {}, DEFAULT_FUNCTION_CALL_GAS, [])],
},
]);
