Authentication is a crucial part of application development as it ensures the security of user data and enhances the user experience. It also allows for personalization and customization of user experiences. In this article, we will guide you through the process of authenticating users in React applications using Appwrite. We will explore the features of Appwrite that enable login and signup functionality, session management, and protected routes.

Introduction to Appwrite
Appwrite is an open-source application that enables developers to integrate backend technology into web applications. It offers various authentication features, including multi-factor authentication, account verification, and recovery. These features make it easier for developers to implement secure user authentication seamlessly.
Prerequisites for Setting up Appwrite in React Projects
Before integrating Appwrite into your React project, make sure you have the following:
– Node.js installed on your device
– Basic understanding of React and JavaScript
– Appwrite account (you can create one for free)
Creating a React app
To create a React app, open the terminal and run the following command:
“`
npx create-react-app userauth
“`
Navigate to the project directory:
“`
cd userauth
“`
Choosing an Appwrite installation method
Appwrite provides different installation options. For this article, we will use the cloud-based deployment option as it is easier to set up and offers better accessibility for users.
Creating an Appwrite project
To integrate Appwrite into your app, you need to be logged in to your Appwrite account. Once logged in, follow these steps:
1. Create a new project.
2. Select “Web App” as the platform.
3. Choose “localhost” as the host and name your app.
4. Open a web browser and navigate to the dashboard.
Installing Appwrite’s SDK in the React App
To integrate Appwrite into your React app, you need to install the Appwrite JavaScript SDK. Follow these steps:
1. Run the following command in the project’s root directory:
“`
npm install appwrite
“`
2. Create a configuration file (Appwrite.js) in the src folder to store the Appwrite endpoint and project ID.
“`
import { Client, Account } from ‘appwrite’;
export const API_ENDPOINT = ‘https://cloud.appwrite.io/v1’;
export const PROJECT_ID = ‘YOUR PROJECT ID HERE’;
const client = new Client()
.setEndpoint(API_ENDPOINT)
.setProject(PROJECT_ID);
export const account = new Account(client);
export default client;
“`
Replace placeholders ‘YOUR_APPWRITE_ENDPOINT’ and ‘YOUR_APPWRITE_PROJECT_ID’ with the Appwrite endpoint and project ID obtained from the Appwrite dashboard.
3. Initialize Appwrite in your React app. In your main index.js or App.js file, import and initialize Appwrite using the configuration file created earlier:
“`
import React from ‘react’;
import ReactDOM from ‘react-dom’;
import App from ‘./App’;
import { Appwrite } from ‘appwrite’;
import appwriteConfig from ‘./appwrite’;
const appwrite = new Appwrite();
appwrite.setEndpoint(appwriteConfig.endpoint).setProject(appwriteConfig.project);
ReactDOM.render(
document.getElementById(‘root’)
);
“`
Building the Main App
Once the configuration is completed, you can start building your app. In this app, we will have login, register, and logout logic that makes use of functionalities from the Appwrite SDK.
Implementing registration functionality
To allow users to create accounts and register in your React app, follow these steps:
1. Create a registration form that collects necessary information such as name, email, and password, and sends it to the Appwrite server for user creation.
2. Create a function that makes an API call to create a new user in the Appwrite server each time the registration button is clicked.
Implementing login functionality
To implement login functionality using Appwrite’s SDK, follow these steps:
1. Create a login form that collects the user’s email and password and sends it to a function that handles the authentication process.
2. If the credentials are valid, the server returns an authentication token that can be stored in the client-side storage for future API calls.
Creating protected pages
To create protected pages that are only accessible to authenticated users, you need to create a function that keeps track of user sessions and restricts access to certain routes based on authentication status.
By following these steps, you can authenticate users in React applications using Appwrite and make use of its features for implementing login and signup functionality, managing user sessions, and protecting routes.
