Building a Job Portal with React - Real-World Project Tutorial

Project Setup and Structure

Start by setting up a new React project using Create React App or your preferred toolchain. Organize your project folders to separate components, pages, and utilities.

A clear folder structure helps maintain the project as it grows.

• Use 'src/components' for reusable UI components.
• Place page-level components in 'src/pages'.
• Keep API calls and utility functions in 'src/utils' or 'src/services'.

Creating Core Components

The job portal requires several core components such as JobList, JobCard, SearchBar, and UserProfile. Each component should focus on a single responsibility.

Use props to pass data and callbacks to child components.

• JobList displays a list of JobCard components.
• JobCard shows job details like title, company, and location.
• SearchBar allows users to filter jobs based on keywords or location.
• UserProfile manages user information and application status.

State Management and Data Handling

Manage job listings and user input using React's useState and useEffect hooks. For larger projects, consider using Context API or state management libraries like Redux.

Fetch job data from an API or mock data for development.

• Store job listings in state to enable dynamic updates.
• Use controlled components for form inputs.
• Implement filtering logic based on user input.
• Handle loading and error states gracefully.

Implementing Navigation with React Router

React Router enables navigation between different pages such as Home, Job Details, and User Profile.

Define routes and link components to create a seamless user experience.

• Set up BrowserRouter at the root of your app.
• Use Route components to map URLs to pages.
• Use Link or NavLink for navigation links.
• Pass parameters via URL for job detail pages.

Example: JobCard Component
