Developer’s Front End Developer Interview Notes – 07 | ReactJS, Javascript, HTML, CSS, Redux

In this tutorial, we will be creating a front end developer interview review application using ReactJS, Javascript, HTML, CSS, and Redux. This application will allow users to review and rate their experiences with different front end developer interviews.

Before we start coding, make sure you have a basic understanding of ReactJS, Redux, HTML, CSS, and JavaScript.

Step 1: Setting up the project
To begin, create a new React project using create-react-app. Open up your terminal and run the following command:

npx create-react-app frontend-interview-review

Once the project is created, navigate to the project directory:

cd frontend-interview-review

Step 2: Installing Redux
Next, we will install Redux and React-Redux to manage our state throughout the application. Run the following commands in your terminal:

npm install redux react-redux

Step 3: Creating components
In the src folder of your project, create the following components:

• InterviewList.js (to display a list of interviews)
• InterviewItem.js (to display individual interview details)
• AddInterview.js (to add a new interview)
• ReviewForm.js (to add a review)
• Rating.js (to display the rating)

Step 4: Setting up Redux
Create a new folder called redux inside the src folder. Inside the redux folder, create the following files:

• actions.js (to define Redux actions)
• reducers.js (to define Redux reducers)
• store.js (to create the Redux store)

In the actions.js file, define the following Redux actions:

export const ADD_INTERVIEW = 'ADD_INTERVIEW';
export const ADD_REVIEW = 'ADD_REVIEW';
export const RATE_INTERVIEW = 'RATE_INTERVIEW';

export const addInterview = (interview) => ({
  type: ADD_INTERVIEW,
  payload: interview
});

export const addReview = (review) => ({
  type: ADD_REVIEW,
  payload: review
});

export const rateInterview = (rating) => ({
  type: RATE_INTERVIEW,
  payload: rating
});

In the reducers.js file, define the initial state and the Redux reducer function:

import { ADD_INTERVIEW, ADD_REVIEW, RATE_INTERVIEW } from './actions';

const initialState = {
  interviews: [],
  reviews: [],
  ratings: []
};

const rootReducer = (state = initialState, action) => {
  switch(action.type) {
    case ADD_INTERVIEW:
      return {
        ...state,
        interviews: [...state.interviews, action.payload]
      };
    case ADD_REVIEW:
      return {
        ...state,
        reviews: [...state.reviews, action.payload]
      };
    case RATE_INTERVIEW:
      return {
        ...state,
        ratings: [...state.ratings, action.payload]
      };
    default:
      return state;
  }
};

export default rootReducer;

In the store.js file, create the Redux store:

import { createStore } from 'redux';
import rootReducer from './reducers';

const store = createStore(rootReducer);

export default store;

Step 5: Implementing components
Now, we will implement the components we created earlier. In each component file, import the necessary React and Redux libraries. Create the necessary UI elements and logic to display and interact with the data.

Step 6: Connecting components to Redux
To connect your components to the Redux store, use the connect function provided by React-Redux. In each component file, import connect from react-redux and the necessary actions.

import { connect } from 'react-redux';
import { addInterview, addReview, rateInterview } from '../redux/actions';

Use the connect function to map the Redux state and actions to the component’s props:

const mapStateToProps = state => ({
  interviews: state.interviews,
  reviews: state.reviews,
  ratings: state.ratings
});

const mapDispatchToProps = {
  addInterview,
  addReview,
  rateInterview
};

export default connect(mapStateToProps, mapDispatchToProps)(ComponentName);

Step 7: Testing the application
Run the following command in your project directory to start the development server:

npm start

Open your browser and navigate to http://localhost:3000 to view your application. Test the functionality of adding interviews, reviews, and ratings to ensure everything is working as expected.

Congratulations, you have successfully created a front end developer interview review application using ReactJS, Javascript, HTML, CSS, and Redux. Feel free to customize the application further and add additional features to improve its functionality. Happy coding!
