Afterwards we can set the populateExchange up by adding it to our list of exchanges in the client options. The Routes component is used to group routes. By doing all this, we will reduce a lot of effort in coding typed hooks ourselves before we can use our GraphQL API in our Next. When the same query and variables are requested again, urql 's default cache will then return the cached result. The top level of my app is wrapped in an <ApolloHooksProvider />. React/Preact. add the filter criteria to the query-key to trigger an automatic refetch (react-query refetches every time the key changes) pass the filter criteria to the fetchFn and then to the backend. We can type useMutation hooks the same way we type useQuery hooks. Urql seems to sit somewhere in between GraphQL Request and Apollo Client, having more features and. # or. The most fundamental difference between the three clients is in their core philosophy.
