Reading transactions from an account

Get the list of transactions where an account is involved.

Prerequisites

Getting into some code

Use the accountHttp repository to get the latest confirmed transactions for a given account.

const accountHttp = new AccountHttp('http://localhost:3000');

const publicKey = process.env.PUBLIC_KEY as string;
const publicAccount =  PublicAccount.createFromPublicKey(publicKey, NetworkType.MIJIN_TEST);

const pageSize = 10; // Page size between 10 and 100, otherwise 10

accountHttp
    .transactions(publicAccount, new QueryParams(pageSize))
    .subscribe(transactions => console.log(transactions), err => console.error(err));
const accountHttp = new AccountHttp('http://localhost:3000');

const publicKey = process.env.PUBLIC_KEY as string;
const publicAccount =  PublicAccount.createFromPublicKey(publicKey, NetworkType.MIJIN_TEST);

const pageSize = 10; // Page size between 10 and 100, otherwise 10

accountHttp
    .transactions(publicAccount, new QueryParams(pageSize))
    .subscribe(transactions => console.log(transactions), err => console.error(err));
nem2-cli account transactions --publickey 7D08373CFFE4154E129E04F0827E5F3D6907587E348757B0F87D2F839BF88246 --numtransactions 10

Note

By default, the SDK provides up to 10 transactions. The page size can be increased up to 100 transactions.

To get more than 100 transactions, you will have to make further requests. For each additional call, add to the QueryParams the optional parameter transactionId with the latest transaction identifier known returned by the previous request.

new QueryParams(pageSize, transactions[transactions.length - 1].transactionInfo.id))
