I am a beginner to web development and I just created this hardhat project to test a smart contract for a charity donation DApp that has the following folder structure:

Now how do I add a frontend to this thing? I first initialized it using npm init, then I added hardhat using npm i hardhat, intialized the hardhat project using npx hardhat init and finally did all the testing yada yada...
Until it was done.

Now how do I add a react frontend to it? I thought about creating another frontend folder here itself in which I'll create all the web pages...
...And it's here where the node modules confusion comes up.

Won't this create 2 node modules folders? One in the main directory, one in the frontend directory?

Is that good practice?
