In this tutorial, you will learn how to start integrating Airstack API into your Node.js application.

Table Of Contents

Step 0: Pre-requisites

Step 1: Install Airstack Node SDK

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

npm install @airstack/node

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

If you are using Node version 20.6.0+, then you can simply import the environment variable to you Node.js app. Thus, directly proceed to the next step.

If you are using Node version earlier than 20.6.0, then you need to install the dotenv package:

npm install dotenv

and import the package to be able to inject the environment variable to your application:

index.js
import { config } from "dotenv";

config();

Step 3: Initialize SDK

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

index.ts
import { init } from "@airstack/node";

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 and Farcaster owned by vitalik.eth:

index.ts
import { fetchQuery } from "@airstack/node";

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

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 main = async () => {
  const { data, error }: QueryResponse = 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"
        }
      ],
      "addresses": ["0xd8da6bf26964af9d7eed9e03e53415d37aa96045"]
    }
  }
}
