How to fetch with parameters using React Query?
In React Query, when we need to make a request and pass parameters, we commonly use the or hooks. Below, I will explain how to pass parameters in both scenarios.UsingIn , parameters can be passed through the parameters of the query function. Typically, this query function is defined by you to fetch data from the server.For example, suppose we want to fetch some user data from an API, where the API endpoint accepts as a parameter to retrieve specific user information:Note that in the above example, the first parameter of is an array containing a string and the variable . This array is referred to as the query key in React Query and is used to uniquely identify and cache the query.Usingis typically used for operations such as POST, PUT, DELETE that modify the server state. Parameters are usually passed when triggering the mutation.For example, if we want to add a new user, we might have a to handle this POST request:In the above example, we define a function that is triggered when the user submits the form. This function calls the function via and passes the user object as a parameter. React Query handles sending the request and updating the state (such as , , and ).Overall, whether using or , React Query provides a very flexible way to pass request parameters and handles many complexities related to request state management.
