React-Moralis

React-Moralis is a library that provides a simple way to integrate the Moralis backend platform with React applications. Moralis is a blockchain backend platform that provides tools to create, scale, and deploy blockchain-based applications.

Features

React-Moralis provides the following features:

• Authentication: You can easily integrate user authentication into your React application using the Moralis User API. With the Moralis User API, you can create, read, update, and delete users, as well as authenticate users using different methods, such as email and username/password.

• Cloud Functions: React-Moralis enables you to call Moralis cloud functions from your React application. With Moralis cloud functions, you can execute server-side logic on the Moralis platform, such as interacting with the blockchain, working with databases, and sending notifications.

• File Storage: React-Moralis provides an easy way to store and retrieve files on the Moralis platform. You can upload and download files, as well as manage file permissions and metadata.

• Real-Time Updates: React-Moralis enables real-time updates in your React application using the Moralis LiveQuery API. With LiveQuery, you can subscribe to data changes in real-time and receive updates as they happen in the Moralis server.

Installation

To install React-Moralis, you need to have Node.js and npm installed on your system. You can install React-Moralis using npm with the following command:

npm install react-moralis

Usage

To use React-Moralis in your React application, you need to import the MoralisProvider component and wrap your app component with it. The MoralisProvider is responsible for initializing and configuring the Moralis SDK and setting up the context for other components to use:

import React from 'react';
import { MoralisProvider } from 'react-moralis';

import App from './App';

function MyApp() {
  return (
    <MoralisProvider appId="yourAppId" serverUrl="https://yourServerUrl.com" >
      <App />
    </MoralisProvider>
  );
}

export default MyApp;

In your application components, you can use the useMoralis hook to access the Moralis SDK and use its methods:

import React from 'react';
import { useMoralis } from 'react-moralis';

function MyComponent() {
  const { authenticate, isAuthenticated, user, logout } = useMoralis();

  return (
    <div>
      {isAuthenticated ? (
        <div>
          <p>Welcome, {user.get('username')}!</p>
          <button onClick={() => logout()}>Log out</button>
        </div>
      ) : (
        <div>
          <button onClick={() => authenticate()}>Log in</button>
        </div>
      )}
    </div>
  );
}

export default MyComponent;
