Apollo 3 caching support

[art049]

Hello, thanks a lot for this amazing package!

I'm currently looking to implement server side caching with Apollo 3 and I didn't find a lot of references.
Any ideas or sample implementations I could use to do it?

Few references of related things I found out here:

• Can i get some guide to use cacheControl with ApolloServer ?
• apollo-cache example doesn't work anymore since apollo-cache-control has been deprecated.
• Directives support with @Directive decorator #369 : Hence it's possible to use @Directive("@cacheControl(maxAge: 60, scope: PUBLIC)") for example. However, Apollo doesn't catch the directives.

Are you able to make a PR that fix this?
I'd love to do that but I didn't find any solution to make it work yet.

You need to declare the directive too by new GraphQLDirective and provide it in build options

thanks for thiis, please can you give me an example of this or point to where the documentation of the graphqldirective is used because i dont see it for type-graphql. i started like this but im not sure its correct or how to implement the apollo directive within it

    const schema = await buildSchema({
        resolvers: [__dirname + "/resolvers/**/*.{ts,js}"],
        emitSchemaFile: path.resolve(__dirname, "../app/lib/graphql/schema.graphql"),
        validate: true,
        directives:[ new GraphQLDirective(...)]
    })

I tried to do this @MichalLytek but unfortunately couldn't get this to work neither.

What do you have exactly inside the new GraphQLDirective(...)?

I tried with this directive added to the schema

 new GraphQLDirective({
  name: "cacheControl",
  locations: ["FIELD_DEFINITION", "OBJECT", "INTERFACE", "UNION"],
  args: {
    maxAge: {
      type: GraphQLInt,
    },
    scope: {
      type: new GraphQLEnumType({
        name: "CacheControlScope",
        values: {
          PUBLIC: { value: "PUBLIC" },
          PRIVATE: { value: "PRIVATE" },
        },
      }),
    },
    inheritMaxAge: {
      type: GraphQLBoolean,
    },
  },
});

The cache ends up working on root queries. But doesn't on field resolvers which is a big issue on my side.
Do you have any idea @MichalLytek ?
