Airstack Web SDK
The Airstack Web SDK provides a convenient way for web developers to integrate Airstack's blockchain functionalities into their applications.
With the provided hooks and components, you can easily query and fetch data from smart contracts and display NFT assets.

Installation
With NPM
npm install @airstack/airstack-react
With yarn
yarn add @airstack/airstack-react
With pnpm
pnpm install @airstack/airstack-react
Getting started
To use the SDK you will need the Airstack API key, once you have it you can call the init
function with the API key or use AirstackProvider
.
init
must be called before any of the SDK hooks or components are used or you can use AirstackProvider, we recommend using init
or AirstackProvider
in the App.ts file.
Example with init
import { init, useQuery } from "@airstack/airstack-react";
init("api-key");
const MyComponent = () => {
const { data, loading, error } = useQuery(query, variables, { cache: false });
if (loading) {
return <p>Loading...</p>;
}
if (error) {
return <p>Error: {error.message}</p>;
}
};
Example with AirstackProvider
import { AirstackProvider, useQuery } from "@airstack/airstack-react";
const App () => {
return (
<AirstackProvider apiKey={"api-key"}>
<MyComponent/>
</AirstackProvider>
)
}
const MyComponent = () => {
const { data, loading, error } = useQuery(query, variables, { cache: false });
if (loading) {
return <p>Loading...</p>;
}
if (error) {
return <p>Error: {error.message}</p>;
}
};
Hooks
All the hooks can take 3 arguments
Argument | Description | Options |
---|
query (required) | The GraphQL query string to be executed. | String |
variables | Variables to be used in the GraphQL query. | Record<string, any> |
configAndCallbacks | Additional configuration and callback options. | ConfigAndCallbacks |
ConfigAndCallbacks Options
Option | Description | Type | Default |
---|
onCompleted | A callback function that will be called when the query is successfully completed. | (data: any) => void | - |
onError | A callback function that will be called when an error occurs during the query. | (error: any) => void | - |
dataFormatter | A function that allows custom formatting of the data before returning it to the user. | (data: any) => any | - |
cache | Determines whether to cache the query result. | boolean | true |
const { data, loading, error } = useQuery(query, variables, { cache: false });
Query Hooks
useQuery
The useQuery
hook loads query data as soon as the component is mounted. It returns an object with the following properties:
data
: the data returned by the query.loading
: a boolean indicating whether the query is currently loading.error
: any error that occurred while loading the query.
Example
import { useQuery } from "@airstack/airstack-react";
const MyComponent = () => {
const { data, loading, error } = useQuery(
query,
variables,
configAndCallbacks
);
if (loading) {
return <p>Loading...</p>;
}
if (error) {
return <p>Error: {error.message}</p>;
}
};
useLazyQuery
The useLazyQuery
hook is used when you want to fetch query data manually, instead of automatically when the component mounts. It returns an array with two items:
fetch
: a function that can be called to execute the query.- An object with the same properties as the object returned by
useQuery
: data
, loading
, and error
.
Example
import { useLazyQuery } from "@airstack/airstack-react";
const MyComponent = () => {
const [fetch, { data, loading, error }] = useLazyQuery(query, variables);
const handleClick = () => {
fetch();
};
if (loading) {
return <p>Loading...</p>;
}
if (error) {
return <p>Error: {error.message}</p>;
}
};
Note: pagination hooks only work with queries that have support for pagination.
The useQueryWithPagination
hook provides a simple way to paginate the data returned by a query. It works the same as the useQuery
hook, but also returns an object with the following properties:
pagination
: an object with the following properties:
hasNextPage
: a boolean indicating whether there is another page of data after the current page.hasPrevPage
: a boolean indicating whether there is another page of data before the current page.getNextPage
: a function that can be called to fetch the next page of data.getPrevPage
: a function that can be called to fetch the previous page of data.
Example
import { useQueryWithPagination } from "@airstack/airstack-react";
const MyComponent = () => {
const { data, loading, pagination } = useQueryWithPagination(
query,
variables,
configAndCallbacks
);
const { hasNextPage, hasPrevPage, getNextPage, getPrevPage } = pagination;
const handleNextPage = () => {
getNextPage();
};
const handlePrevPage = () => {
getPrevPage();
};
if (loading) {
return <p>Loading...</p>;
}
if (error) {
return <p>Error: {error.message}</p>;
}
};
The useLazyQueryWithPagination hook is used when you want to manually fetch paginated data. It returns an array with two items:
fetch
: a function that can be called to execute the query.- An object with the same properties as the object returned by useQueryWithPagination:
data
, loading
, and pagination
.
The fetch
function can be called whenever you want to execute the query, for example, in response to a user action like clicking a button to load more data. The hook returns the data
, loading
, and pagination
properties just like useQueryWithPagination.
Here's an example of using useLazyQueryWithPagination:
import { useLazyQueryWithPagination } from "@airstack/airstack-react";
function Component() {
const [fetchData, { data, loading, pagination }] = useLazyQueryWithPagination(
query,
variables
);
const loadMore = () => {
if (pagination.hasNextPage) {
pagination.getNextPage();
}
};
return (
<div>
<button onClick={fetchData}>Fetch Data</button>
<ul>
{data.map((item) => (
<li key={item.id}>{item.name}</li>
))}
</ul>
{pagination.hasNextPage && <button onClick={loadMore}>Load More</button>}
{loading && <p>Loading...</p>}
</div>
);
}
In the example, we define a loadMore
function that gets called when a user clicks a "Load More" button. The loadMore
function checks if there is a next page using pagination.hasNextPage
and calls pagination.getNextPage()
to fetch the next page of data.
Note that when using useLazyQueryWithPagination
, you will need to handle the fetching of the initial data yourself. In the example, we call the fetchData
function to fetch the initial data when the user clicks the "Fetch Data" button.
Components
Asset
The Asset
component can be used to load and display NFT assets in your React application.
Props
chain
(optional): a string representing the blockchain network to use. Defaults to "ethereum"
.address
(required): a string representing the contract address of the NFT.tokenId
(required): a string representing the token ID of the NFT.loading
(optional): a React node to show while the asset is loading.error
(optional): a React node to show if there is an error loading the asset.imgProps
(optional): an object of HTML image attributes to pass to the underlying image element.preset
(optional): a string representing the size of the asset image to display. Can be one of "extraSmall"
, "small"
, "medium"
, "large"
, or "original"
. Defaults to "medium"
.
Example
import { Asset } from "@airstack/airstack-react";
function App() {
return (
<div>
<Asset
chain="ethereum"
address="0x...",
tokenId="tokenId"
loading={<div>Loading...</div>}
error={<div>Error loading asset.</div>}
imgProps={{alt: "my asset"}}
preset="medium"
/>
</div>
);
}
fetchQuery
fetchQuery can be used in places where using hooks is not possible. fetchQuery
accepts the same parameter as hooks.
Note: fetchQuery only accepts config and does not accept callbacks in the third parameter.
fetchQuery
returns a promise with an object, which contains the following properties:
data
: The response data returned by the server.error
: An error object, if an error occurred during the network request.
Example
import { fetchQuery } from "@airstack/airstack-react";
const { data, error } = await fetchQuery(query, variables, config);
fetchQueryWithPagination
takes the same parameter as fetchQuery
.
It returns a promise with an object, which contains the following properties:
data
: The response data returned by the server.error
: An error object, if an error occurred during the network request.hasNextPage
: A boolean that indicates whether there is a next page of data available.hasPrevPage
: A boolean that indicates whether there is a previous page of data available.getNextPage()
: A function that returns the next page of data. Returns null
if there is no next page.getPrevPage()
: A function that returns the pråevious page of data. Returns null
if there is no previous page.
Note: fetchQueryWithPagination only works with queries that have support for pagination.
Example
import { fetchQueryWithPagination } from "@airstack/airstack-react";
const { data, error, hasNextPage, hasPrevPage, getNextPage, getPrevPage } =
await fetchQueryWithPagination(query, variables, config);
