NEAR Basics, Connect, Wallet, Account, Call Methods

basics.js

// new near instance (for NodeJS use InMemoryKeyStore)

// do this once somewhere when app "mounts" or loads

const near = new Near({
    networkId,
    nodeUrl,
    walletUrl,
    deps: {
        keyStore: new keyStores.BrowserLocalStorageKeyStore()
    },
});

const account = new Account(near.connection, [ACCOUNT_ID]);
// or use walletAccount
const wallet = new WalletAccount(near);

// now with either "wallet" or "account" you can call methods of your contract!

await account.viewFunction(contractId, methodName, { ... args ... });

await account.functionCall({
    contractId: ...,
    methodName: ...,
    args: { ... },
    gas: ...,
    attachedDeposit: ...
});
