create-react-app with TypeScript & Firebase Authentication [JavaScript]


Let’s implement a whole authentication mechanism in React with sign up, sign in, password reset, change password and sign out in TypeScript.

🏀 GitHub Repository

Whole files of this tutorial are as follows:

https://github.com/morizyun/react-typescript-firebase-auth

🚜 Get Firebase App info

It will be needs for using Firebase authentication.

🍮 create-react-app with TypeScript

You can install create-react-app on command line:

# If you have not install it yet, please do:
yarn global add create-react-app # npm install -g create-react-app

# Create new project
create-react-app react-ts-firebase-auth --scripts-version=react-scripts-ts
cd react-ts-firebase-auth

# Install Firebase and react-router-dom (React Router)
yarn add firebase react-router-dom

yarn add --dev @types/react-router @types/react-router-dom

After then, you can run app process by yarn start on terminal and open http://localhost:3000.

Also, please create some directories:

🐞 Configuration

Please change tslint.json to add as follows:

{
+ "rules": {
+ "jsx-no-lambda": false
+ }
}

🗽 Rebuild folders

# Create folders
mkdir src/components
mkdir src/constants
mkdir src/firebase
mkdir -p src/pages/Account
mkdir src/pages/Admin
mkdir src/pages/Home
mkdir src/pages/Landing
mkdir src/pages/PasswordForget
mkdir src/pages/SignIn
mkdir src/pages/SignUp

# Move files for App
mv src/components/App.ts src/components/App.ts

# Remove unused files
rm src/logo.svg
rm src/App.test.ts
rm src/App.css

🗻 Constants

Add src/constants/routes.ts file:

export const SIGN_UP = "/signup";
export const SIGN_IN = "/signin";
export const LANDING = "/";
export const HOME = "/home";
export const ACCOUNT = "/account";
export const PASSWORD_FORGET = "/password_forget";
