• 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 JS/TS 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:

AIRSTACK_API_KEY=YOUR_AIRSTACK_API_KEY

Depending on the JavaScript framework that you are using, you might need to specify a specific naming convention for your environment variables, e.g. vue needs VUE_APP_AIRSTACK_API_KEY

Step 3: Initialize SDK

You can use init from the SDK to initialize it with the Airstack API key:

TypeScript

index.ts

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

init(process.env.AIRSTACK_API_KEY);

JavaScript

index.js

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

init(process.env.AIRSTACK_API_KEY);

Step 4: Call Your Query

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

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

For more query examples, check out Guides for various use cases you can build with Airstack.

TypeScript

index.ts

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

interface QueryResponse {
  data: Data;
  error: Error;
}

interface Data {
  Wallet: Wallet;
}

interface Error {
  message: string;
}

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

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

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

const main = async () => {
  const { data, error }: QueryResponse = await fetchQuery(query);

  if (error) {
    throw new Error(error.message);
  }

  console.log(data);
};

main();

JavaScript

index.js

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

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

const main = async () => {
  const { data, error } = await fetchQuery(query);

  if (error) {
    throw new Error(error.message);
  }

  console.log(data);
};

main();

The data variable will return and logged into your terminal as follows:

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