I listened to the lecture to get the overall flow before proceeding with the toy project and it was helpful. I think I could feel directly that GraphQL is more flexible by changing from Rest to GraphQL, but as someone who is hearing about GraphQL for the first time, it was difficult to understand, so I looked up other contents. In particular, I think I need to look into the React query part on the client side more to apply it directly. However, it seems that React query definitely has advantages. As someone who listened to it after finishing the boot camp, it felt like I dealt with a newer technology(?) rather than a simple full-stack toy project, so it was difficult but satisfying to listen to it because it will be a scope of study in the future.
