React integration

To use the Polywrap React integration, you'll need to install the @web3api/react package.

npm install --save @web3api/react


Once installed, the first step is to add the Web3ApiProvider to your DOM. This will instantiate an instance of the Web3ApiClient for all queries within the nested DOM hierarchy to use.

To use the provider, simply wrap it around whatever DOM hierarchy you'd like to use Polywrap within:

import React from 'react';
import { Web3ApiProvider } from '@web3api/react';
export default function App() {
return (
<div>{'Polywrap enabled dApp goes here!'}</div>

Web3ApiProvider Props#

The Web3ApiProvider component's props are the same as the Web3ApiClient constructor's arguments. For example, you can configure redirects like so:

<Web3ApiProvider redirects={ [...] }/>

Multiple Web3ApiProviders#

If you need to use multiple providers, you can do so using the createWeb3ApiProvider("...") method, which accepts the name of your provider as an argument. For example:

import { createWeb3ApiProvider } from '@web3api/react';
const CustomWeb3ApiProvider = createWeb3ApiProvider('custom');
<Custom />


usePolywrapQuery (loading, etc)

After enabling your React application with the Web3ApiProvider, you may now use the useWeb3ApiQuery hook to send Polywrap queries!

Here's what our "hello world" query from above would look like if we used this method.

const { execute, data, errors, loading } = useWeb3ApiQuery({
uri: 'ens/api.helloworld.polywrap.eth',
query: `{
logMessage(message: "Hello World!")

By default, the useWeb3ApiQuery hook uses the first Web3ApiProvider found in the DOM's hierarchy. If you'd like to specify a specific provider to be used, simply set the provider: property:

provider: 'custom',
