GraphQL is a novel query language proposed by Facebook to implement Web-based APIs. In this paper, we will present a practical analysis of graphql api’s while integrating with react js. First, we will see how graphql works in web applications and How we can integrate it with react js. After that, we will work on the vulnerability finder tools to check the loopholes in the api’s. For the result, we will show the various vulnerability issues in graphql and provide the solution to fix those issues.
