Overview

The challenge

Users should be able to:

• View the optimal layout for the app depending on their device's screen size
• See hover states for all interactive elements on the page
• Create, Read, Update, and Delete comments and replies
• Upvote and downvote comments
• Bonus: If you're building a purely front-end project, use localStorage to save the current state in the browser that persists when the browser is refreshed.
• Bonus: Instead of using the createdAt strings from the data.json file, try using timestamps and dynamically track the time since the comment or reply was posted.

My process

Built with

• Semantic HTML5 markup
• CSS custom properties
• Flexbox
• localStorage - to save states in the browser
• Mobile-first workflow
• immerjs - A tiny package that allows you to work with immutable state in a more convenient way
• React Timestamp - A React Component for displaying a datetime in local timezone
• React - JS library
• TailwindCSS - CSS framework

What I learned

I gained experience working with react's useReducer hook and immer.js combined I also learnt how to use the react-timestamp component.

const findComment = (comments, commentId, nestKey) => {
    for(const key in comments) {
        const comment = comments[key];

        if(comment.id === commentId) {
            return comment;
        }
        if(comment[nestKey] && comment[nestKey].length !== 0) {
            const foundReply = findComment(comment[nestKey], commentId, nestKey);
            if(foundReply) {
                return foundReply;
            }
        }
    }
    return null;
}

Continued development

I would like to improve my problem solving skills and build more complex components in the future!

Useful resources

• React Documentation - I worked with the react documentation while building, it helped better my understanding of some concepts.
• Tailwind Documentation - I used it in learning styling based on variables or conditional tailwind styling, if you will.
