Building a Simple To-Do App with Firebase, Redux, and React
Firebase and Redux are two powerful tools that can help you build scalable and efficient applications. In this article, we’ll explore how to use them together to create a simple to-do app with user authentication.
What is React-Redux-Firebase?
React-Redux-Firebase is a library that provides Redux bindings for Firebase, making it easier to use Firebase with Redux and React. It also comes with some Hooks to simplify the implementation of Firebase functionality.
Prerequisites
Before we dive into the tutorial, make sure you have a good understanding of React, Redux, and Firebase. You’ll also need basic knowledge of React Router.
Setting Up the Project
To get started, create a new React project and install the necessary dependencies, including Redux, React-Redux, Firebase, React-Redux-Firebase, Redux-Firestore, and React-Router-Dom.
Setting Up Firebase
Next, set up a new Firebase project and enable the Cloud Firestore and authentication services. Create a new Cloud Firestore database and set up authentication with Google and email/password providers.
Configuring React-Redux-Firebase
Create a new file called reducers.js and combine your reducers into one root reducer for your Redux store. You’ll also need to set up React-Redux-Firebase by creating an object called rrfConfig and specifying the collection name for storing user data.
Building the App
Now it’s time to build the app. Create components for adding to-do items, signing in, and displaying to-do items. Use React-Redux-Firebase’s Hooks to implement Firebase functionality, such as logging in with Google and storing to-do items in Cloud Firestore.
The SignIn Component
The SignIn component allows users to sign in with Google using the useFirebase Hook. Once signed in, the user is redirected to the Todos route.
The PrivateRoute Component
The PrivateRoute component checks whether the user is authenticated before rendering the route component.
The AddTodo Component
The AddTodo component allows users to add new to-do items, which are stored in a subcollection called “todos” inside each user document.
The TodoItem Component
The TodoItem component displays each to-do item with a checkbox to mark tasks as completed.
The Todos Route
The Todos route displays the user’s name and a list of all to-do items, using the useFirestoreConnect Hook to listen to the “todos” subcollection.
Putting it All Together
Finally, piece together all the components and routes in your App.js file. With that, you’ve built a simple to-do app with user authentication using Firebase, Redux, and React!
Next Steps
In a real-world app, you should set up security rules to ensure user data is secure. You can also explore the React-Redux-Firebase documentation for more features and customization options.
