Introduction

Welcome to the IIT Bodies channel! In this article, we will be discussing the second part of our meme generator project. If you haven't watched the first part yet, be sure to check the description for the video link. In the first part, we successfully stored all the memes in our Redux store. Now, we will focus on displaying these memes on the client side.

Setting up the Project

To get started, open your text editor and navigate to the app.js component. We need to import the connect function from the react-redux package in order to connect React and Redux. In the mapStateToProps function, we will return the array of memes from our state. Wrap the component with connect, passing mapStateToProps as the first parameter and null as the second.

Importing and Connecting React and Redux

In the app.js component, import the connect function from react-redux. Use the connect function to connect React and Redux. Pass the mapStateToProps function as the first parameter and null as the second parameter.

Mapping State to Props

Inside the mapStateToProps function, return the array of memes from our state. Access the memes using this.props.memes.

Displaying Meme Names

To display the name of each meme, add a new h4 tag below the existing h2 tag inside the render method. Pass the index of the meme as the key and access the name of the meme using meme.name.

Limiting the Number of Memes Displayed

In order to limit the number of memes displayed, create a constructor in the component. Use the super method to call the superclass constructor and initialize the memeLimit state variable to 10 (or any desired limit).

Adding a "Load More" Button

To provide the option to load more memes, add a button with the class name "meme-button" and the text "Load More Memes". Attach an onClick event handler to the button that increases the memeLimit state variable by 10.

Styling the Meme List

Create a new folder called "styles" in the source directory. Inside this folder, create a CSS file named "index.css". Add styling rules to align the memes in the center of the page, set the background color to black, and change the font family and color.

Creating a Meme Item Component

Create a new component called MemeItem.js and import React. In the MemeItem class component, set the render method to return a div element that displays the image and name of the meme.

Adding Animation to the Meme Item

To add animation to the meme item, create a constructor in the MemeItem component. Initialize the isHovered state variable to false. Inside the render method, add an onMouseEnter event handler to set isHovered to true when the mouse enters the meme image. Similarly, add an onMouseLeave event handler to set isHovered to false when the mouse leaves the image.

Conclusion

Congratulations! You have successfully implemented the second part of our meme generator project. Now, you can display and interact with the memes on the client side. In the next part, we will add functionality to create custom memes using a form. Stay tuned for more updates!

Frequently Asked Questions

Q: How can I limit the number of memes displayed on the client side? A: You can set a limit by initializing the memeLimit state variable in the constructor and passing the limit value to the slice method when mapping the memes array.

Q: How do I add a "Load More" button to display additional memes? A: Add a button with an onClick event handler that increases the memeLimit state variable when clicked.

Q: Can I customize the styling of the meme list? A: Yes, you can modify the CSS rules in the index.css file in the styles folder to customize the appearance of the meme list.

Q: How do I add animation to the meme item on mouse hover? A: Use the onMouseEnter and onMouseLeave event handlers to toggle the isHovered state variable. Then, apply CSS animation using the animation property and keyframes to achieve the desired effect.
