• Completed Get API Key

• Git

• Node v.16+

Step 1: Install Airstack Web SDK

Use a package manager to install the Airstack Web SDK into your Next.js project:

npm

npm install @airstack/airstack-react

yarn

yarn add @airstack/airstack-react

pnpm

pnpm install @airstack/airstack-react

Step 2: Set Environment Variable

Create a new .env file:

touch .env

Add the Airstack API key as the environment variable:

NEXT_PUBLIC_AIRSTACK_API_KEY=YOUR_AIRSTACK_API_KEY

Step 3: Initialize SDK

Wrap your component with the AirstackProvider from the SDK to initialize it with the Airstack API key:

Page Router (TS)

_app.tsx

import { init, AirstackProvider } from "@airstack/airstack-react";

export default function App({ Component, pageProps }) {
  return (
    <AirstackProvider apiKey={process.env.NEXT_PUBLIC_AIRSTACK_API_KEY ?? ""}>
      <Component {...pageProps} />
    </AirstackProvider>
  )
};

Page Router (JS)

_app.jsx

import { init, AirstackProvider } from "@airstack/airstack-react";

export default function App({ Component, pageProps }) {
  return (
    <AirstackProvider apiKey={process.env.NEXT_PUBLIC_AIRSTACK_API_KEY ?? ""}>
      <Component {...pageProps} />
    </AirstackProvider>
  )
};

Step 4: Call Your Query

Once you have initialized the SDK, you can use the useQuery to call the Airstack API.

Below you have been provided with Airstack query to fetch the 0x address and Farcaster owned by vitalik.eth:

TypeScript

index.tsx

import { useQuery } from "@airstack/airstack-react";

interface QueryResponse {
  data: Data | null;
  loading: boolean;
  error: Error | null;
}

interface Data {
  Wallet: Wallet;
}

interface Error {
  message: string;
}

interface Wallet {
  socials: Social[];
  addresses: string[];
}

interface Social {
  dappName: "farcaster";
  profileName: string;
}


const query = `
query MyQuery {
  Wallet(input: {identity: "vitalik.eth", blockchain: ethereum}) {
    socials {
      dappName
      profileName
    }
    addresses
  }
}
`;

const Component = () => {
  const { data, loading, error }: QueryResponse = useQuery<Data>(query, {}, { cache: false });

  if (loading) {
    return <p>Loading...</p>;
  }

  if (error) {
    return <p>Error: {error.message}</p>;
  }

  // Render your component using the data returned by the query
  console.log(data);
}

export default Component;

JavaScript

index.jsx

import { useQuery } from "@airstack/airstack-react";

const query = `
query MyQuery {
  Wallet(input: {identity: "vitalik.eth", blockchain: ethereum}) {
    socials {
      dappName
      profileName
    }
    addresses
  }
}
`;

const Component = () => {
  const { data, loading, error } = useQuery(query, {}, { cache: false });

  if (loading) {
    return <p>Loading...</p>;
  }

  if (error) {
    return <p>Error: {error.message}</p>;
  }

  // Render your component using the data returned by the query
  console.log(data);
};

export default Component;

The data variable will return and logged into your browser's console as follows:

{
  "data": {
    "Wallet": {
      "socials": [
        {
          "dappName": "farcaster",
          "profileName": "vitalik.eth"
        }
      ],
      "addresses": ["0xd8da6bf26964af9d7eed9e03e53415d37aa96045"]
    }
  }
}
