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.

What I learned

With this challenge, I learned how to build an API with ExpressJS and deploy it to Heroku. I also learned how to manage a Redux-like global state with React native hooks useContext and useReducer.

Useful resources

• Replace Redux with useReducer - This helped me to use useReducer and useContext to replace Redux in TypeScript.
• Node.js, Express.js, and PostgreSQL: CRUD REST API example - This helped me to build my REST API with ExpressJS and PostgreSQL.
