# Installation The best way to access Request Network is using the Request Network SDK with a Request Node. In this way, the Request Node operator pays the protocol fee for creating requests and reduces the number of transactions signed by the end user resulting in a better user experience. The Request Network SDK is split into multiple packages so that Builders can pick and choose the features they need. ## SDK Packages These are the packages that we think would be most commonly used by Builders to build applications.

Package	Description
`@requestnetwork/request-client.js`	Create, update, and retrieve requests.
`@requestnetwork/web3-signature`	Sign requests using web3 wallets like Metamask
`@requestnetwork/epk-signature`	Sign requests using Ethereum private keys
`@requestnetwork/data-format`	Standards for data stored on Request, like invoice format
`@requestnetwork/epk-decryption`	Decrypt encrypted requests using Ethereum private keys
`@requestnetwork/payment-processor`	Pay a request using a web3 wallet
`@requestnetwork/request-node`	Web server that allows easy access to the Request system
`@requestnetwork/currency`	Tools for managing currency definitions

For a list of internal SDK packages, see [Internal SDK Packages](#internal-sdk-packages). ## Component Packages These packages offer pre-built components for quickly integrating certain Request Network features.

Package	Description
`@requestnetwork/create-invoice-form`	A form for creating invoices in Request Network
`@requestnetwork/invoice-dashboard`	A dashboard for viewing and paying invoices in Request Network
`@requestnetwork/add-stakeholder`	A dialog box for granting third-party access to an encrypted invoice created via Request Finance

## Import the packages The Request Client library can be imported as ES6 or CommonJS modules. {% tabs %} {% tab title="ES6" %}

import { RequestNetwork } from '@requestnetwork/request-client.js';
import { Web3SignatureProvider } from '@requestnetwork/web3-signature';
import { payRequest } from '@requestnetwork/payment-processor';

{% endtab %} {% tab title="CommonJS" %} ```tsx const { RequestNetwork } = require('@requestnetwork/request-client.js'); const { Web3SignatureProvider } = require('@requestnetwork/web3-signature'); const { payRequest } = require("@requestnetwork/payment-processor"); ``` {% endtab %} {% endtabs %} ## Internal SDK Packages These packages are published publicly but contain functions that are considered internal to the [SDK Packages](#sdk-packages). It is less likely that a Builder would need to use these packages.

Package	Description
`@requestnetwork/advanced-logic`	Extensions to the protocol
`@requestnetwork/data-access`	Indexing and batching of transactions
`@requestnetwork/ethereum-storage`	Storage of Request data on Ethereum and IPFS, with custom indexing
`@requestnetwork/multi-format`	Serialize and deserialize object in the Request Network protocol
`@requestnetwork/payment-detection`	Payment detection, to compute the balance.
`@requestnetwork/request-logic`	The Request business logic: properties and actions of requests
`@requestnetwork/smart-contracts`	Sources and artifacts of the smart contracts
`@requestnetwork/thegraph-data-access`	Storage of Request data on Ethereum and IPFS, indexed by TheGraph
`@requestnetwork/transaction-manager`	Creates transactions to be sent to Data Access, managing encryption
`@requestnetwork/types`	Typescript types shared across @requestnetwork packages
`@requestnetwork/utils`	Collection of tools shared between the @requestnetwork packages
