QuickNode SDK

:warning: This is an beta release This release is not production-ready yet and only meant as a technical preview. The API could break in subsequent beta releases until the 1.0.0 release is finalized.

A SDK from QuickNode making it easy for developers to interact with QuickNode's services.

QuickNode's SDK is a JavaScript and TypeScript framework-agnostic library that supports both CommonJS and ES module systems.

Currently the SDK makes it even easier to use the QuickNode Graph API to query market insights, trading data, transactions by wallets and contracts, cached NFT images, and more!

:grey_question: We want to hear from you! Please take a few minutes to fill out our QuickNode SDK feedback form and let us know what you currently think about the SDK. This helps us further improve the SDK.

Getting Started

Installation

• Requires Node.js v16 or higher
• npm install @quicknode/sdk or yarn add @quicknode/sdk

Quickstart

import QuickNode from '@quicknode/sdk';

const qn = new QuickNode.API({ graphApiKey: 'my-api-key' });

qn.nfts
  .getByWallet({
    address: 'quicknode.eth',
    first: 5,
  })
  .then((response) => console.log(response));

Full example app implementation here

API functions

These functions return data from the powerful QuickNode Graph API, making it even easier to use.

Configuration

Sign up for a QuickNode account to use the multi-chain QuickNode Graph API API key in the SDK. The API functions in the SDK (and the underlying Graph API) can be used without an API key, but its usage will be heavily rate limited, intended for trial and development purposes only. For more information, please see QuickNode's Graph API documentation

import QuickNode from '@quicknode/sdk';

const qn = new QuickNode.API({
  graphApiKey: 'my-api-key', // which is obtained by signing up on https://www.quicknode.com/signup
  defaultChain: 'ethereum',
});

A defaultChain can be set to set the chain for all calls. Currently we support:

• ethereum Ethereum Mainnet
• ethereumSepolia Ethereum Sepolia
• polygon Polygon Mainnet

The defaultChain in the initializer can be overridden with the chain argument in functions.

If no defaultChain is passed into the initializer or a chain argument to a function,ethereum is used by default.

Configuration Arguments

graphApiKey	string	❌	The QuickNode GraphQL API Key	abcd1234
defaultChain	string	❌	The default chain to use for all functions (defaults to ethereum)	polygon

graphApiClient.query

A way to send GraphQL queries directly to the QuickNode GraphQL API. graphApiClient is an Urql client instance configured to use QuickNode's Graph API. For more information about the query structure, see the Graph API documentation

import QuickNode, { gql } from '@quicknode/sdk';

const qn = new QuickNode.API({
  graphApiKey: 'my-api-key', // which is obtained by signing up on https://www.quicknode.com/signup
});

const query = gql`
  query ($contractAddress: String!) {
    ethereum {
      collection(contractAddress: $contractAddress) {
        address
        name
        symbol
        totalSupply
      }
    }
  }
`;
const variables = {
  contractAddress: '0x2106c00ac7da0a3430ae667879139e832307aeaa',
};

qn.graphApiClient.query({ query, variables }).then(({ data }) => console.log(data));

Error handling

The input to API functions is validated at runtime in order to handle both untyped JavaScript input and user input in end user applications. In short, this will help prevent you sending invalid Graph API queries because of bad input. The validation is done by zod under the hood and we expose the errors to you in a QNInputValidationError instance.

For example, you can handle these errors:

import QuickNode from '@quicknode/sdk';

const qn = new QuickNode.API({ graphApiKey: 'my-api-key' });

// Inside async function
try {
  const eventsByContract = await events.getByContract({
    contractAddress: userInput, // Input comes from the user, we don't know what will be here
  });
  return eventsByContract;
} catch (error) {
  if (error instanceof QNInputValidationError) {
    console.error(error.stack);
    return { errors: error.issues }; // Return formatted issues to handle as needed by UI or user
  } else {
    // handle unexpected errors here
  }
}

The QNInputValidationError instance has the following properties:

Property	Type	Description
messages	string[]	An array of concise error messages
zodError	ZodError	The full ZodError instance, see the Zod error handling docs for more information
issues	ZodIssue[]	An array of Zod Issue instances, which is a formatted error data structure

timestamp can be a date-time string at UTC, such as 2007-12-03T10:15:30Z, compliant with the date-time format outlined in section 5.6 of the RFC 3339 profile of the ISO 8601 standard for representation of dates and times using the Gregorian calendar.

Pagination

For functions that support pagination, use the first property to specify the amount of results to return.

The returned data.tokensPageInfo.endCursor property in the response can be used to access subsequent results. This value can be passed in to the after property and will return the results after that endCursor.

hasNextPage can be used to determine the end of the results, where it will be false.

For example, if a response contains:

{
  "results": [...],
  "pageInfo": {
    "endCursor": "T2Zmc2V0Q29ubmVjdGlvbjox",
    "hasNextPage": true,
    "hasPreviousPage": false,
    "startCursor": "T2Zmc2V0Q29ubmVjdGlvbjow"
  }
}

calling the following will get the next page of results

qn.nfts.getByWallet({
  address: 'quicknode.eth',
  after: 'T2Zmc2V0Q29ubmVjdGlvbjox', // Using the endCursor
});

You can do the same with before and return the results before the specified cursor if hasPreviousPage is true

For example, if the response contains the following:

{
  "results": [...],
  "pageInfo": {
    "endCursor": "T2Zmc2V0Q29ubmVjdGlvbjo2",
    "hasNextPage": true,
    "hasPreviousPage": true,
    "startCursor": "T2Zmc2V0Q29ubmVjdGlvbjoy"
  }
}

calling the following will get the previous page of results

qn.nfts.getByWallet({
  address: 'quicknode.eth',
  before: 'T2Zmc2V0Q29ubmVjdGlvbjoy', // Using the startCursor
});

Issues

Please submit any issues or feature requests as an issue in Github.

Development

We recommend using the example application to develop

1. In qn-oss monorepo root directory, run yarn install
2. cd packages/apps/examples/sdk-api from qn-oss monorepo root
3. cp .env.example .env and add api key
4. nx serve apps-examples-sdk-api
5. Then you can send requests to the API, for example: curl http://localhost:3333/api/nftsByAddress/0xbc08dadccc79c00587d7e6a75bb68ff5fd30f9e0

Running tests

Run nx test libs-sdk to execute the tests via Jest.

API responses are recorded using polly.js. You can re-record live requests by passing in an API key, copy .env.test.example to .env.test and fill out with your API key.

Running linting

Run nx lint libs-sdk to execute the lint via ESLint.

Generate graphql codegen typings

Generate graphql typings via Codegen.

1. navigate to packages/libs/sdk from qn-oss monorepo root
2. cp .env.example .env and add api key
3. run yarn run codegen
