What feature do we want to add?

On my website, reedbarger.com, I allow users to copy code from my articles with the help of a package called react-copy-to-clipboard.

A user just hovers over the snippet, clicks the clipboard button, and the code is added to their computer's clipboard to enable them to paste and use the code, wherever they like.

Recreating react-copy-to-clipboard

Instead of using a third party library, however, I wanted to recreate this functionality with my own custom React hook. As with every custom react hook I create, I put it a dedicated folder, usually called utils or lib, specifically for functions that I can reuse across my app.

We'll put this hook in a file called useCopyToClipboard.js and I'll make a function of the same name. Also make sure to import React up at the top.

There are various ways that we can copy some text to the user's clipboard. However, I prefer to use a library for this, which makes the process more reliable called copy-to-clipboard.
