If a user is authenticated, store it in the local state and pass the authenticated user object down to all components that are interested in it. In the previous section, you created a Firebase project on the official Firebase website. After you've mastered the basics of React, I always recommend moving on to advanced topics like authentication, authorization, and connecting React applications to databases. The relevant property from the router props is the history object, because it allows us to redirect a user to another page by pushing a route to it. You will implement the protection of the route using authorization mechanisms for this application. So you only need to use one or the other but make sure you are consistent with which one you use!

The input field has an onChange handler while the button has an onClick handler so create the respective handlers just above render: In React, we also need to bind the handler to the component so get the correct this scope in the handler. I also love traveling, running, rollerskating, and puppies. Create a Firebase Application. Connect Firebase to your app to start using it. Lets also add a link that takes you back to the puppies page. Since the users are objects rather than lists when they are retrieved from the Firebase database, you have to restructure them as lists (arrays), which makes it easier to display them later: Remember to remove the listener to avoid memory leaks from using the same reference with the off() method: Render your list of users in the AdminPage component or in a child component. The real authorization logic happens in the componentDidMount() lifecycle method. It defines two new functions: one to get a reference to a user by identifier (uid) and one to get a reference to all users: The paths in the ref() method match the location where your entities (users) will be stored in Firebase's realtime database API. This has not been created yet so update the state variables to include it. Now that we have the secrets taken care of, lets configure Firebase within the app. Create deleteNote and add this code: We get the path of the note and call .remove(). To do this, install recompose for your application on the command line: You can use recompose to organize your higher-order components. Well start by using the incredibly handy `create-react-app` package in order to quickly set up a new React project without having to worry about any build configuration. The file implements a password forget link as a component which isn't used directly in the form component. You should be able to visit the /signup route in your browser after starting your application to confirm that the form with all its input fields shows up.

Next, set up a Firebase project in your browser: Now, lets add these secrets to a .env file, and also add the .env file to your .gitignore so the secrets stay secure: Lets also create our Realtime Database. Lets begin with the backend api. Hopefully these steps and the source code can get you moving much quicker than I was initially! Once the user enters correct information, the login reducer will be activated, and it will update the user state to the logged in users state. Make sure the corresponding OAuth client ID and secret are also specified. When any item removed from the firebase, the value event will be fired and the listener set in the componentDidMount will be called. Optionally, introduce a test for your App component and test the application. The admin page is protected on a more fine-grained level, because it is only accessible for authenticated admin users. This is where all your components will be implemented. The realtime database rules are defined as key-value pairs as well. Side note: The UI is atrocious, I know! Let's implement this higher-order component in the src/components/Firebase/context.js: Next, make it available via our Firebase module in the src/components/Firebase/index.js file: Now, instead of using the Firebase Context directly in the SignUpPage, which doesn't need to know about the Firebase instance, use the higher-order component to wrap your SignUpForm. Now lets get these potluck items to actually display on the page. Source Code Projects: This application is only build with React and Firebase. Moreover, we have also implemented React Navigation in our project as well. Now, enough talking, let us jump into this React Firebase Example. To complete the Firebase setup we need to specify an authentication method. One of the tabs youll notice is Rules which is how we set access levels on the contents of the database. For the sake of readability, I split up the commands into multiple lines: In each folder, create an index.js file for the component. DEV Community A constructive and inclusive social network for software developers. For now, you have successfully implemented fundamental routing for this application.

Copy that whole config object, and head back over to your React project. At the top level, we have a node all_notes where all the users notes will be stored. This is often the point where developers start to use a state management library like Redux or MobX. Our users wont have to access to our database so lets set up our client web app that will give them a friendlier interface to interact with their data. From the command line, head to your src/ folder and execute it: Second, create a components/ folder in your application's src/ folder on the command line. The SignOut component shouldn't show up for a non authenticated user, for example. First, lets create a variable called items inside of default state. The input fields need to update the local state of the component by using a onChange handler. This way, we can use the initial state object to reset the state after a successful sign up. Restricted area! To keep the App component clean and concise, I like to extract the session handling for the authenticated user to a separate higher-order component in a new src/components/Session/withAuthentication.js file: Move all logic that deals with the authenticated user from the App component to it: As you can see, it also uses the new React Context to provide the authenticated user. Now we need to follow a similar process for the Toys component! A persistent, real-time backend for your application to plug in to! Second, there will be a landing page and a home page.

You can download the starter code or just fork it on codesandbox and modify directly in your browser. Also, the application now passes the authenticated user implicitly via React's Context, rather than explicitly through the component tree using props. If a route matches a path prop, the respective component will be displayed; thus, all the page components in the App component are exchangeable by changing the route, but the Navigation component stays fixed independently of any route changes. We live in the future. Google's Firebase is a cloud-based database hosting service that will set up a database for you and host it, as well as offer you the tools to interact with it. In this tutorial, we'll focus on the Realtime database and explore how the security rules secure the integrity of the data in our database. You only need a form component to use it. Let's paste the implementation details for the higher-order component and go through it step-by-step: The render method displays the passed component (e.g. Find your `src` folder, and create a file called `firebase.js`.

This will give us a clear picture of how to add, access, and associate data in our Realtime Database. The book continuous with the usual delete and update operations to organize your users in the realtime database. We can then call firebase.database()s remove method, which strips it from the page. It's also possible to use the SignUpForm as standalone without the SignUpPage, because it is responsible to get the Firebase instance via the higher-order component. This tutorial builds on the previous tutorial on Firebase authentication. // Create a user in your Firebase realtime database, React Application Setup: create-react-app, Session Handling with Higher-Order Components, Password Reset and Password Change with Firebase, Protected Routes in React with Authorization, Manage Users with Firebase's Realtime Database in React, Git and keep track of your changes by having your project on GitHub, visual Firebase setup and introduction guide, Firebase Authentication with E-Mail/Password, Firebase's realtime database setup for Web, how to read and write data to Firebase's realtime database. For example, with just a few more steps (and perhaps we will go over this in a future article), it would be incredibly easy to expand this application so that users could log in and out, be able to have a display photo next to the item that they are bringing, and only be able to remove their own items. But before we do that, we have to write an API route to communicate with the database! Copy these in the next step to your React application. First well need to connect to Firebase in order to do this, well start by importing our firebase module that we created earlier. Now it's time to use the authentication functionalities in your React components, which we'll build from scratch. Rather than using a render prop component, which is automatically given with React's Context Consumer component, it may be simpler to use a higher-order component. Firebase stores data as a giant object with key-value pairs. Login using your Google Account - You will be able to create a new project in only 3 Steps. Firebase Basics with React in Examples | by Artem Diashkin | LITSLINK | Medium 500 Apologies, but something went wrong on our end. It uses the Link component of React Router to enable navigation to different routes. First, enhance the HomePage component with the higher-order component and define the authorization condition for it: Second, enhance the AccountPage component with the higher-order component and define the authorization condition. If you want to grab it, just go here and copy and paste the raw contents you find there into your `src/App.css` file! All the necessary information passed to the authentication API can be destructured from the local state. Firebase Configuration Go to the functions tab and click on the Get Started button: Functions Dashboard You will see a dialogue box which has instructions on How to set up the Firebase Functions. 1. You want to show nothing if the authenticated user doesn't meet the condition's criteria. Without a database, this poses an issue, since every time we refresh the page any new dishes that were added to the potluck would get lost. First, make the admin page available via your Navigation component: Next, the AdminPage component's componentDidMount() lifecycle method in src/components/Admin/index.js is the perfect place to fetch users from your Firebase realtime database API: We are using the users reference from our Firebase class to attach a listener. Firebases ability to persist data on the fly, coupled with Reacts component life cycle, makes for an incredibly simple and powerful way to quickly build up simple applications. Thats not all Firebase does, it can do more things like handle user authentication and store files, but well be mainly focusing on data storage. Firebase is a backend-as-a-service platform that conveniently provides a number of essential services under one roof. You can imagine how this technique gives control over authorizations, not just by broader authorization rules, but more specific role-based and permission-based authorizations. npx create-react-app --template typescript firebase-auth-tutorial Essentially what this is going to do is boilerplate a react app that is using typescript. It manages the local state of a authUser object, and then passes it to the Navigation component. Read and Write Operations: In the application, you created a user and display a list of users with real-time capabilities. A sign up automatically results in a sign in/login by the user. Like the withAuthentication higher-order component, there is a withAuthorization higher-order component to shield the authorization business logic from your components. To complete the authentication loop, next we'll implement the sign out component. Only users with the admin role are authorized. Then click create database. Well be using .set since we are generating our own unique note id. - services/tutorial.service.js exports TutorialDataService that uses firebase's Firestore CollectionReference to interact with Firestore. Start the application and reset your password. 1 React project; Firebase configuration. You can go ahead to delete all_notes/0001. We first check to see if note.content has a value. There was a time when font-awesome played a more prominent role in this tutorial, but I took it out to try and keep it as simple as possible :). However, the higher-order component should be able to receive a condition function passed as parameter. The best place to add user creation is the SignUpForm component, as it is the most natural place to save users after signing up via the Firebase authentication API. Let's take a step back from the higher-order components, React Context API, and session handling. npm install firebase react-router-dom react-firebase-hooks Here, we are installing firebase to communicate with Firebase services, and we are also installing react-router-dom to handle the routing of the application. ), A field where the user can submit their name. Nice article. Each node under that is a users id and its children would be an array of notes. It lets users sign up if they don't have an account, and it is found on the sign in page. Yaaa, because googles DB is needed. If you haven't used React Router before, it should be straightforward to pick up the basics throughout building this application. 1. In this scenario, we are interested to keep the latest list of users though. In this post we will walk through firebase login with react app. We all really appreciate the time and effort that went into this article. Follow this visual Firebase setup and introduction guide to learn more about Firebase's dashboard and features. Just one question from a newbee : how is the index.js started from the index.html (there is no [direct] reference there to the js scripts) ? It doesn't matter if you are authenticated or not. While, logout reducer will set the user state to null, which will update across the entire app, thanks to the redux. If you have ever coded in React before, you will definitely know App.js file in react projects. A field where the user can enter what food theyre bringing to the potluck. Enter a name for the project and click continue, 2. Now, it uses the higher-order component to make the authenticated user available for all other components below of the App component: Start the application and verify that it still works. In your App component, you can specify which components should show up according to corresponding routes with the help of the Route component from React Router. Lets build out a rough HTML skeleton for our application. Plain React in 200+ pages of learning material. Then it's fine if the listener is too late to redirect the user, because the higher-order component didn't show the protected component. Everything in the following sections regarding authentication is considered extra, to improve the developer's experience and add a couple of useful features along the way. Once suspended, mshahryiar will not be able to comment or publish posts until their suspension is removed. When an action is dispatched for state change, its the reducers duty to make the necessary change to the state and return the new state of the application. Select Start in test mode and click Enable. If sign in succeeds, the local state is updated with the initial state and the user is redirected again. Prerequisite: node.js, npm, react.js (tutorial to install) Once we verify that the latest node.js, npm, react.js is installed using following commands. However, you should make sure not to store the password or any other sensitive data of the user on your own. Our APIs in, Now lets create a simple form in our Toys component that saves the toy name on state. Youll notice that it automatically causes a new list item to appear on the page! It is a redirect to the sign up page, but not used on the sign up page itself. To verify the user creation is working, retrieve all the users from the realtime database in one of your other components. Once downloaded, you can run it by: Which would open a new tab in your default browser with the app. Syntax sugar: async and awaitJavascript Promises: part III, Avoiding Code Duplication by Adding an API Layer in JavaScript, Caching Google and Facebook Login Authentication Data Locally in a React-Native & Redux Application, Reacting to html events | Observer design pattern, Lets begin by setting up our app. In addition, it is an API that enables the integration of online chat functionality into their websites. This will eventually hold all of the potluck items that are currently being tracked inside of our Firebase database. Sometimes the Firebase website doesn't make it easy to find this page. You already created the src/components/Account/index.js file and matched the route in the App component. Modify the code that renders the notes like so: We add a button that calls a method editNote and passes note_id to the method. Finally, once all the keys are iterated over (and therefore all items are grabbed from our database), we update the state with this list of items from our database. Create Firebase Project. From the dashboard, click on the icon. It's also possible to use Firebase within your React components. i have list of movies in fb and that are rendered on the app component. Each note will have: With this structure in place, we can fetch a users note by querying all_notes/uid. Resources. Let's start by implementing the password forget feature. It is used for users who are not authenticated and forgot about their password. The problem with the rule is that its global which means it affects every node in the database. Since we can use the previously-defined authentication API to sign out a user, passing functionality to a button in a React component is fairly straightforward. Here, instead of grabbing all of the items as we did before when adding a new item, we instead look up a specific item by its key (that strange Kk8lHSMqC5oP6Qai0Vx key from before). home page, account page). Add another API request to create a user when the sign up is successful. To begin with, Redux is state management for your react app. Let's implement the routing with React Router before we dive into Firebase for the realtime database and authentication/authorization. Let's implement all the input fields to capture the information in the render method of the component. Finally, well need to add a button to our UI with an onClick that calls our removeItem method and passes it the items key, like follows: And thats all there is to it! A better way is to compose the higher-order components instead. You used the React Context API to pass down the Firebase instance to any component before. Firebase is a backend platform for building Web, Android and IOS applications. This is an opportunity to familiarize yourself with Firebase project's dashboard while you search for the configuration. Its injected into the page using Webpack dev server. Dont forget to import withFirebase and export the component withFirebase too! Once you add your web app to Firebase, you will have access to Firebase Config file, which will let you connect to Firebase and use required resources. It will become hidden in your post, but will still be visible via the comment's permalink. In the sections afterward, you will use the interface of the Firebase class in your React components. This time if you try to add a note with a length less than or equal to 5, the app throws an error. Then it is up to you whether you want to use Firestore or Firebase's Realtime Database. For instance, a user should be able to visit a public landing page, and also use sign up and sign in pages to enter the application as an authenticated user. And now add the handleSubmit method to your component: Now try adding a new item, and hitting submit! When were finished, it will look like this: This article assumes you already have some basic knowledge of how React works and maybe built a few small apps with React. Create a new project. Well fix that later in the .If you have ever interacted with an API, youll probably be familiar with the JSON format: This is the same structure used by NoSQL-like databases like the Realtime database to store data. First, the App component will use the Navigation component that is not implemented yet. Go to https://console.firebase.google.com/, 3. We set up all the routes for your application, configured Firebase and implemented the authentication API for your Firebase class. useDispatch Next you will be asked if you want Google Analytics for your project. It will capture the user information such as username, email, and password. Go to Firebase Console, login with your Google Account, then click on Add Project. The data storage ability of Firebase make it a perfect fit for React. Thanks for keeping DEV Community safe. This comprehensive tutorial walks you through a real-world application using React and Firebase. Here is what you can do to flag mshahryiar: mshahryiar consistently posts content that violates DEV Community 's Since you already implemented the interface in your Firebase class, you can use it in components. To start, sign up on the official Firebase website. The state is initialized by an object destructuring. Previously, you created basic components for each page component used by our routes. Firebase with React. A class method (onSubmit) ensures the information is send to the API. We added a basic version of session handling in the last section. You can consolidate all the routes of your application in a well-defined src/constants/routes.js constants file: Each route represents a page in your application. A Store can be created with the help of reducers which holds the entire state of the application. First, initialize the realtime database API for your Firebase class as you did earlier for the authentication API: Second, extend the interface for your Firebase class for the user entity. This comment thread is closed. It provides an end-to-end identity solution, supporting email and password accounts, phone authentication and social media logins. In the src/components/PasswordChange/index.js file add the following component: The component updates its local state using onChange handlers in the input fields. Create editNote method: We get a reference to the all_notes/${this.state.user.uid}/${note_id} which is where the note is stored. Since the higher-order components don't depend on each other, the order doesn't matter. I think your project idea would be a great use case for React Router. Next.js is a server-side rendering framework based on React, which is search engine optimized. Heres what our completed `App.js` should look like: Now you can truly see how Firebase and React play beautifully together. We created Login Reducer earlier, which helps us to stores user information. One refinement can be made in the withAuthorization higher-order component using the authenticated user from the context: The improvement in the render method was needed to avoid showing the protected page before the redirect happens. After you have created a Firebase account, you should be able to create projects and be granted access to the project dashboard. Open up `src/App.js`, and remove the `App` component, replacing it with this basic skeleton: Ive prepared a little bit of CSS for you to paste into the `App.css` file, just so that our app doesnt look totally bland. The on() method registers a continuous listener that triggers every time something has changed, the once() method registers a listener that would be called only once. It makes sense, because then you can associate other domain entities (e.g. Consider ways to protect the Account page and make it accessible only for authenticated users. That config object is important though: its how we authenticate our React application with our Firebase database. Let's implement the login with Firebase now. We just map over it and print the results on to the page, like so: Try adding a new item through your form. Instead, the Navigation component uses the new context to consume the authenticated user: The application works the same as before, except any component can simply use React's Context to consume the authenticated user. Firebase Deployment: The final step in the book is to deploy an application with Firebase. In, Great, now were ready to officially hook up our app to our Firebase database. We will create Firebase functions for Login and Register, we will add toast messages for errors, and we will add private routes using session-based authentication. Step 1: Install React Native. Made with love and Ruby on Rails. Let's see where the authUser (authenticated user) comes from in the App component. Publish the rules and refresh the app again. Enter any name for your project then click Register, then click Continue to Console, 8. But with Firebase, this is a snap to fix! If so, how do I do that? I find it exciting to build a well-rounded application with you, because it can be used as a boilerplate project that gives you authentication, authorization, and a database. Finally, you can use the username as well to provide additional information about your user. To update data, we fetch the content using the note_id, populate the input field with the content and update the data with the new content. Well be building something called Fun Food Friends, a web application for planning your next potluck, which hopefully feels like something rather real world, in that you can imagine using these technologies in your own production projects. In the, Lets use Firebase to create a simple app that lets us list puppies and record their favorite toys. Add this in the src/components/PasswordForget/index.js file: The code is verbose, but it it's no different from the sign up and sign in forms from previous sections. In Firebase, the RESTful URI becomes a simple path, and the HTTP methods become Firebase's API. If mshahryiar is not suspended, they can still re-publish their posts from their dashboard. Also, it uses the Router component provided by React Router. The error objects from Firebase have this message property by default, so you can rely on it to display the proper text for your application's user. The callback here, which weve called snapshot, provides you with a birds eye overview of the items ref inside of your database. Congratulations, you signed up your first user via Firebase authentication. This comprehensive tutorial walks you through a real-world application using React and Firebase. I am interested in seeing what you will build on top of it! It uses the password forget and password change forms in a central place. of a user and the implementation of the onSubmit class method when a user signs up eventually. If you try running it now, you will not see the new notes being added but if you check the Firebase console you will see the data there. I try to put most of the code in one block, because the components are not too small, and splitting them up step by step might be too verbose. The password forget uses a form to submit the information (email address) needed by the Firebase authentication API to reset the password. This should take you to the Firebase console, which looks something like this: Now lets create our projects database. For the App component in src/components/App/index.js, it could look like the following: Fix the relative path to the App component in the src/index.js file. If a user signs out, the authUser object becomes null, so the authUser property in the local state is set to null and all components depending on it adjust their behavior (e.g. Well do this by creating a constructor() hook for our app and setting a default value for our inputs state there: Well add a onChange event handlers to our inputs, as well as providing them with a value derived from our state (this is called a controlled input), like this: And finally, well create a catch-all handleChange method that receives the event from our inputs, and updates that inputs corresponding piece of state: If you arent familiar with using brackets to dynamically determine key name in an object literal, check out the MDN docs on computed properties. You may see something like this in your browser: This is because we have not added our configuration details yet. DigitalOcean provides cloud products for every stage of your journey. Optionally, you can create a second Firebase project on the Firebase website to have one project for your development environment and one project for your production environment.
