Creating a Component to Display HDD Results

Oct 13, 2025 by miodeya.com 8 views

Introduction

In this article, we will explore how to display HDD search results, providing a seamless user experience by showing a message if the movie is already downloaded on the HDD. This feature is crucial for users who want to quickly access their downloaded content without having to navigate through multiple menus.

Acceptance Criteria

To ensure that our implementation meets the requirements, let's break down the acceptance criteria:

Given

The user has searched for a movie

When

The movie is found in the HDD

Then

Display a message with the file path(s)

Technical Details

To implement this feature, we will use the following technologies:

React: A popular JavaScript library for building user interfaces
TailwindCSS: A utility-first CSS framework for styling our component
Unit Testing: We will write unit tests to ensure that our component behaves as expected

Creating a Component to Display HDD Results

Let's create a new component called HddResults that will display the message with the file path(s).

HddResults Component

import React from 'react';

const HddResults = ({ hddResults }) => {
  if (!hddResults) return null;

  return (
    <div className="bg-gray-200 p-4 rounded-lg">
      <h2 className="text-lg font-bold mb-2">Movie Found on HDD</h2>
      <ul>
        {hddResults.map((result, index) => (
          <li key={index} className="mb-2">
            <strong>File Path:</strong> {result.filePath}
          </li>
        ))}
      </ul>
    </div>
  );
};

export default HddResults;

In this component, we are using the hddResults prop to display the file path(s) of the movie found on the HDD. We are also using TailwindCSS to style the component.

Styling the Message using TailwindCSS

Let's use TailwindCSS to style the message with the file path(s).

HddResults Component (Updated)

import React from 'react';

const HddResults = ({ hddResults }) => {
  if (!hddResults) return null;

  return (
    <div className="bg-gray-200 p-4 rounded-lg">
      <h2 className="text-lg font-bold mb-2">Movie Found on HDD</h2>
      <ul>
        {hddResults.map((result, index) => (
          <li key={index} className="mb-2">
            <strong className="text-blue-500">File Path:</strong> {result.filePath}
          </li>
        ))}
      </ul>
    </div>
  );
};

export default HddResults;

In this updated component, we are using TailwindCSS to style the message with the file path(s). We are using the text-blue-500 class to style the "File Path:" text.

Writing Unit Tests for this Component

Let's write unit tests for this component using Jest and Enzyme.

HddResults Component (Test)

import React from 'react';
import { shallow } from 'enzyme';
import HddResults from './HddResults';

describe('HddResults component', () => {
  it('should render null if hddResults is null', () => {
    const wrapper = shallow(<HddResults hddResults={null} />);
    expect(wrapper.isEmptyRender()).toBe(true);
  });

  it('should render the message with the file path(s)', () => {
    const hddResults = [
      { filePath: '/path/to/movie1.mp4' },
      { filePath: '/path/to/movie2.mp4' },
    ];
    const wrapper = shallow(<HddResults hddResults={hddResults} />);
    expect(wrapper.find('h2').text()).toBe('Movie Found on HDD');
    expect(wrapper.find('ul').children().length).toBe(2);
  });
});

In this test, we are testing two scenarios:

The component should render null if hddResults is null.
The component should render the message with the file path(s) if hddResults is an array of objects.

Conclusion

Introduction

In our previous article, we explored how to display HDD search results, providing a seamless user experience by showing a message if the movie is already downloaded on the HDD. In this article, we will answer some frequently asked questions (FAQs) related to this feature.

Q: What is the purpose of displaying HDD search results?

A: The purpose of displaying HDD search results is to provide a seamless user experience by showing a message if the movie is already downloaded on the HDD. This feature is crucial for users who want to quickly access their downloaded content without having to navigate through multiple menus.

Q: How do I implement this feature?

A: To implement this feature, you will need to create a new component called HddResults that displays the message with the file path(s). You will also need to use TailwindCSS to style the component and write unit tests for this component using Jest and Enzyme.

Q: What are the technical details required to implement this feature?

A: The technical details required to implement this feature include:

React: A popular JavaScript library for building user interfaces
TailwindCSS: A utility-first CSS framework for styling our component
Unit Testing: We will write unit tests to ensure that our component behaves as expected

Q: How do I style the message with the file path(s) using TailwindCSS?

A: To style the message with the file path(s) using TailwindCSS, you can use the following classes:

bg-gray-200: Sets the background color to a light gray
p-4: Sets the padding to 4 units
rounded-lg: Sets the border radius to a large value
text-lg: Sets the font size to a large value
font-bold: Sets the font weight to bold
text-blue-500: Sets the text color to a blue color

Q: How do I write unit tests for this component?

A: To write unit tests for this component, you can use Jest and Enzyme. You will need to create a test file that imports the HddResults component and uses the shallow function from Enzyme to render the component. You can then use the expect function from Jest to assert that the component behaves as expected.

Q: What are some best practices for implementing this feature?

A: Some best practices for implementing this feature include:

Separate concerns: Keep the logic for displaying HDD search results separate from the logic for styling the component.
Use a consistent naming convention: Use a consistent naming convention for the component and its props.
Write unit tests: Write unit tests to ensure that the component behaves as expected.
Use a utility-first CSS framework: Use a utility-first CSS framework like TailwindCSS to style the component.

Conclusion

In this article, we have answered some frequently asked questions (FAQs) related to displaying HDD search results. We have covered topics such as the purpose of displaying HDD search results, how to implement this feature, technical details required to implement this feature, styling the message with the file path(s) using TailwindCSS, writing unit tests for this component, and best practices for implementing this feature.
