This repo contains an authentication-based app boilerplate that follows SOLID principles and design patterns.
The app boilerplate provides a clean and organized structure for building authentication-based applications using React. It includes features such as user registration, login, and logout, as well as password reset and email verification.
The code is written in an extensible way, making it easy to add new features or modify existing ones. It also includes comprehensive documentation and unit tests to ensure code quality and maintainability.
npm install
npm start
react-redux(withredux-tookit) for state managementreact-router-domfor routingreact-hook-form(withyup) for form validation
prettierfor code formatting@trivago/prettier-plugin-sort-importsfor sorting imports
- Used kebab case for all file names including components files for imports consistency.
- Added
jsconfig.jsonfile to allow absolute imports fromsrcfolder. .prettierrcfile is included in the repo, but you can use your own and runnpm run formatto format the code.- Used
tailwindcssfor styling the app but feel free to use any other styling library.
Saves time and effort by providing a centralized location for managing the authentication state, localStorage, and auth-based redirections of the app.
