Simple but powerful chat application that everybody can use to communicate using text messages. It's like a Discord server or a Slack room with a single channel. To enter the chat and interact with people, the user must log in using their Google account. Once logged in, the user can read their previous messages and start sending messages. All messages are stored in a Firestore database and are synced in real-time with this React application.
Typing indicator: notifies the recipient when a user starts typing a chat to them
User status: indicates whether the user is online or offline
We'll create a login function that uses Firebase Authentication to sign in a user via a Google sign-in. We'll store the authenticated user in state and make this information and the login function available to components through the Context API. We'll also use Firestore SDK functions to read from and write to our database. A custom hook that reads database messages will allow components to get the latest synchronized data.
In the project directory, you can run:
Runs the app in the development mode.
Open http://localhost:3000 to view it in your browser.
The page will reload when you make changes.
You may also see any lint errors in the console.
Launches the test runner in the interactive watch mode.
See the section about running tests for more information.
Builds the app for production to the build
folder.
It correctly bundles React in production mode and optimizes the build for the best performance.
The build is minified and the filenames include the hashes.
Your app is ready to be deployed!
See the section about deployment for more information.
Note: this is a one-way operation. Once you eject
, you can't go back!
If you aren't satisfied with the build tool and configuration choices, you can eject
at any time. This command will remove the single build dependency from your project.
Instead, it will copy all the configuration files and the transitive dependencies (webpack, Babel, ESLint, etc) right into your project so you have full control over them. All of the commands except eject
will still work, but they will point to the copied scripts so you can tweak them. At this point you're on your own.
You don't have to ever use eject
. The curated feature set is suitable for small and middle deployments, and you shouldn't feel obligated to use this feature. However we understand that this tool wouldn't be useful if you couldn't customize it when you are ready for it.
