Multiple schema directives syntax in @graphql-tools/schema v8

[vladshcherbin]

Hey 👋

After @graphql-tools/schema update to v8 seems like schemaTransforms is missing from makeExecutableSchema. Directive docs suggest wrapping schema in directive:

v7

makeExecutableSchema({
  typeDefs,
  schemaTransforms: [
    userDirectiveTransformer,
    validUserDirectiveTransformer
  ]
})

v8

userDirective()(validUserDirective()(makeExecutableSchema({
  typeDefs
})))

What's the syntax for multiple directives? Is example above suggested one or I'm missing something?

schemaTransforms has been removed so you can chain the functions that manipulate the schema by yourself.
For example;

const directiveTransformers = [userDirectiveTransformer, validUserDirectiveTransformer];
const schema = directiveTransformers.reduce((schema, transformer) => transformer(schema), makeExecutableSchema({ typeDefs }))

I created this codesandbox, tried your method here, but it does not work for me. is there something I am not doing correct?

Just linking to this here: #3279

Thanks! Yeah, I've seen #3279, using reducer is okay though I much prefer syntax of v7 as friendlier one.

Since multiple directives sound like a common case, would be nice to see such example with reducer in the docs so other devs immediately see solution 😉

Would you create a PR that improves the documentation like that?

Another solution that can be used is to use mapSchema

schema = mapSchema(schema, {
        [MapperKind.OBJECT_FIELD]: (field) => {
            directiveLogic1(field, directiveName1, schema);
            directiveLogic2(field, directiveName2, schema);
        },
 });   

const directiveLogic1 = (field, directiveName1, schema) => {
    const dateFormatDirective = getDirective(schema, field, directiveName1);

    if (dateFormatDirective && dateFormatDirective[0]) {
       .....
    }
}
