Introduction

Welcome back! In this video, we're going to be building an authentication app using a backend as a service called Apprite. We'll be using Apprite's easy-to-use cloud platform to Create a login system and fetch protected routes for our users. Throughout this video, I'll explain each step of the process and provide best practices along the way. So, let's dive right in and get started!

Setting Up the App

The first step is to sign up for an account on cloud.apprite.io. It's completely free to sign up, and once You do, you'll need to create a project. Simply click on the "Create Project" button and give it a name. Make sure to note down the project ID, as we'll need it for authentication later on.

Next, we'll need to set up our development environment. Open up your terminal and navigate to the directory where you want to create your app. Once there, use the following command to create a new React Native app:

npx react-native init [app_name]

Replace [app_name] with the desired name for your app. Once the app is created, navigate into the project directory and open it in your preferred code editor.

To ensure our app has the necessary dependencies, we'll need to install a few packages. Run the following commands to install the required packages:

npm install react-navigation

npm install react-native-screens

npm install react-native-ui-kitten

npm install react-native-config

npm install react-native-snackbar

npm install react-native-vector-icons

Next, create a file called .env in the root directory of your project. In this file, add the following:

API_ENDPOINT=[your_api_endpoint]

APPRISE_PROJECT_ID=[your_project_id]

Replace [your_api_endpoint] with the URL of your Apprite API endpoint and [your_project_id] with your Apprite project ID.

With the setup complete, let's move on to creating an account.

Creating an Account

To create an account for the user, we'll need to implement the createUserAccount function. This function will take an email, password, and name as arguments. It will use the Apprite SDK's createUser method to create the account.

Here's an example of how to implement the createUserAccount function:

async function createUserAccount(email, password, name) {
  try {
    const userAccount = await appriteClient.createUser(email, password, name);
    return userAccount;
  } catch (error) {
    console.error("Error in creating user account:", error);
    Snackbar.show({
      text: "Error creating user account",
      duration: Snackbar.LENGTH_LONG,
    });
  }
}

By using the await keyword, we ensure that the function waits for the account creation process to complete before moving on. If an error occurs, we display an error message using the Snackbar component from the react-native-snackbar Package.

Now that we have the account creation functionality in place, we can move on to implementing the login functionality.

Logging in

To log in the user, we'll call the loginUserAccount function. This function will take an email and password as arguments and use the Apprite SDK's loginUser method to authenticate the user.

Here's an example of how to implement the loginUserAccount function:

async function loginUserAccount(email, password) {
  try {
    const session = await appriteClient.loginUser(email, password);
    return session;
  } catch (error) {
    console.error("Error in logging in user account:", error);
    Snackbar.show({
      text: "Error logging in user account",
      duration: Snackbar.LENGTH_LONG,
    });
  }
}

Similar to the createUserAccount function, we use the await keyword to wait for the login process to complete. If an error occurs, we display an error message using the Snackbar component.

With the login functionality in place, we can now move on to getting the current user details.

Getting Current User Details

To fetch the details of the currently logged-in user, we'll use the getCurrentUser function. This function will call the Apprite SDK's getUser method, which returns the user details.

Here's an example of how to implement the getCurrentUser function:

async function getCurrentUserDetails() {
  try {
    const userDetails = await appriteClient.getUser();
    return userDetails;
  } catch (error) {
    console.error("Error getting current user details:", error);
    Snackbar.show({
      text: "Error getting user details",
      duration: Snackbar.LENGTH_LONG,
    });
  }
}

Again, we use the await keyword to wait for the process to complete. If an error occurs, we display an error message using the Snackbar component.

Now that we can get the current user details, let's move on to implementing the logout functionality.

Logging Out

To log out the user, we'll call the logoutUser function. This function uses the Apprite SDK's logout method to terminate the user's session.

Here's an example of how to implement the logoutUser function:

async function logoutUser() {
  try {
    await appriteClient.logout();
  } catch (error) {
    console.error("Error logging out user:", error);
    Snackbar.show({
      text: "Error logging out user",
      duration: Snackbar.LENGTH_LONG,
    });
  }
}

Again, we use the await keyword to wait for the process to complete. If an error occurs, we display an error message using the Snackbar component.

With the logout functionality in place, we have completed the basic authentication features of our app.

Conclusion

In this video, we learned how to create an authentication app using the Apprite backend as a service. We covered the process of creating an account, logging in, fetching current user details, and logging out. By following the steps outlined in this video, you can easily implement authentication in your React Native app. Remember to handle errors gracefully and provide helpful feedback to the user. Thank you for watching, and happy coding!

Highlights

• Built an authentication app using the Apprite backend as a service
• Implemented account creation, login, fetching user details, and logout functionality

• Handled errors using Snackbar component from react-native-snackbar package
• Created a reusable service class for handling authentication logic

FAQ

Q: Can I use a different backend service instead of Apprite? A: Yes, you can adapt the code to work with other backend services or implement your own backend.

Q: How secure is the login process? A: The security of the login process depends on the implementation of your backend service and the measures you take to protect user data.

Q: Can I use this code in my existing React Native project? A: Yes, you can integrate this code into your existing project by following the setup steps and adapting the code to fit your project's structure and requirements.
