How to make a query in Apollo Client properly?

Graphql in apollo client: local data is not normalized
0 I want to normalize (i.e. flatten nested elements) my graphql’s local cache for efficiency reasons (otherwise a change in a nested item would redraw all components). My understanding was that Apollo would automatically normalize the cache… but apparently it seems like I misunderstood. Indeed, if I do: const IS_LOGGED_IN = gql` query IsUserLoggedIn {…

Apollo client: how to create client-side mutations
0 TL;DR: In Apollo client, how can I create client mutations usable with useMutation now that local resolvers are removed? (useful for debug, abstraction, reusability…) Long version: I’m learning how to use Apollo client to deal with a local nested state. For now, I’m using something like: client.writeQuery({ query: IS_LOGGED_IN, data: { isLoggedIn: false, },…

Apollo Client: switch between local and remote server
0 Currently I’m creating an http link with a relative URI. This works when the server is running locally, and also works when the client and server are hosted remotely: const httpLink = createHttpLink({ uri: ‘/.netlify/functions/foo’, }); const authLink = setContext((_, { headers }) => { const token = process.env.REACT_APP_TOKEN return { headers: { …headers,…

Why apollo client removes some properties (sets them to null) from a cached object spontaneously?
0 I’m using @apollo/client version 3.7.3 in a react.js, typescript application. After fetching a list of objects from the server, some values are removed from the cache spontaneously! So when the client gets the data from the server, it stores them in the cache to be used in the UI and the cache version is…
