Hello DoYoung Ahn! This is such an encouraging review. Thank you so much for the excessive praise 😃 One of the reasons I personally wanted to upload it for free was because I felt that the usage rate of GraphQL in Korea is still lower compared to other countries, and I wanted to promote it. I'm so glad if it gave you strength and helped you, DoYoung Ahn 😊😊 Thank you again for the review!
