# List Transactions

In the basic examples we still show how to use SignumJS depending the way you are using SignumJS, i.e. imported via NodeJS package manager or as minified bundle. In case you haven't read about the module system, take a quick look there:

{% content-ref url="/pages/5LpyrKz8NZepdbWjzEW9" %}
[Modules](/signumjs/getting-started/modules.md)
{% endcontent-ref %}

{% hint style="info" %}
A fully working example is available [here](https://github.com/signum-network/signumjs/blob/main/examples/nodejs/basic/listTransactions.js)
{% endhint %}

Following functions from SignumJS are used in this example 

* [composeApi](https://signum-network.github.io/signumjs/modules/core_api.html#composeapi) function to create the api instance
* [api.account.getAccountTransactions](https://signum-network.github.io/signumjs/interfaces/core_api.accountapi.html#getaccounttransactions) function to fetch the transactions from the blockchain
* [Address](https://signum-network.github.io/signumjs/classes/core.address.html) Value Object to parse and convert the given address 
* [Amount](https://signum-network.github.io/signumjs/classes/util.amount.html) Value Object to convert between Planck and Signa
* [ChainTime](https://signum-network.github.io/signumjs/classes/util.chaintime.html) Value Object to convert between blockchain timestamp and real date

        const accountId = Address.create(account).getNumericId()
