is it possible to generate typing for the cache object of apollo client?

[jingjiezhou2021]

Hi,

I’m using graphql-codegen with apollo-client. Everything works great except one thing:

I tried to update cache after mutation, the update function of client.mutate doesn’t have typings for the cache parameter(more specifically it is of ApolloCache<any>), I expected it to be typed based on the graphql schema so that i can modify the desired field in cache data very easily.

Example:

const client = createApolloClient();
await client.mutate({
	mutation: updateNFTsOfUserProfile,
	update(cache, { data }) {	
        // cache is ApolloCache<any> here
	},
	variables: {...},
});

You can access cache property on the client instance which has type ApolloCache<NormalizedCacheObject> but this is not connected with graphql schema.

Either way when you try to modify the fields in the cache data there is no typing specifying the fields, you will have to manually input the name of the field

client.cache.modify({
	fields:{
        // fields are of Partial<{[x: string]: Modifier<any>;}> | AllFieldsModifier<Record<string, any>>
	}
})

I couldn’t find any mention of this in the docs

Questions:

• Is there a way to enable typing for the cache object?
• If not, is this a known limitation or something that could be supported?.
