This project was bootstrapped with Create React App.
Below you will find some information on how to perform common tasks.
You can find the most recent version of this guide here.
After creation, your project should look like this:
my-app/
README.md
index.html
favicon.ico
node_modules/
package.json
src/
App.css
App.js
App.test.js
index.css
index.js
logo.svg
For the project to build, these files must exist with exact filenames:
index.html
is the page template;favicon.ico
is the icon you see in the browser tab;src/index.js
is the JavaScript entry point.
You can delete or rename the other files.
You may create subdirectories inside src
. For faster rebuilds, only files inside src
are processed by Webpack.
You need to put any JS and CSS files inside src
, or Webpack won’t see them.
You can, however, create more top-level directories.
They will not be included in the production build so you can use them for things like documentation.
In the project directory, you can run:
Runs the app in the development mode.
Open http://localhost:3000 to view it in the browser.
The page will reload if you make edits.
You will 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!
The database emulators provided by Firebase allow you to run the full application on a database the is emulated locally. This means that the data will be cleared each time you start the emulator. To use the emulator run the following:
- Start the emulators:
yarn emulate
- Start the app:
yarn dev
Checkout the auth recipes for some simple examples of how to integrate auth.
Warning: You need to handle the loading state of auth! The recipes go over this, but as mentioned in this issue here, it can seem unclear initially.
