Metrom React

Collection of React hooks a for seamless and efficient integration with Metrom.

Installation

The hooks rely on wagmi  under the hood, so a few required packages must be installed, alongside @metrom-xyz/react:

pnpm add @metrom-xyz/react wagmi viem @tanstack/react-query
# or
yarn add @metrom-xyz/react wagmi viem @tanstack/react-query
# or
npm add @metrom-xyz/react wagmi viem @tanstack/react-query

Setup

A couple configuration steps are required before being able to use the Metrom hooks.

External dependencies

Once installed, set up the Wagmi and TanStack configuration, then wrap your React app with the required context providers by following the official wagmi documentation .

Wrap app in context provider

Wrap your app with the MetromProvider React Context Provider and pass the environment you wish to target the environment property.

The Environment is exported by the library.

import { Environment, MetromProvider } from "@metrom-xyz/react";
 
function App() {
  return (
    <MetromProvider environment={Environment.Development}>
      {/** ... */}
    </MetromProvider>
  );
}

Omitting the environment will default to development.

Usage

Once the setup is done, the hooks can be used in any React component:

import { useClaims } from "@metrom-xyz/react";
 
function Component() {
  const { claims, loading } = useClaims({ address: "..." });
 
  if (loading) return <div>loading claims...</div>;
 
  return <div>...</div>;
}
