7.10.0 (2020-02-05)

Features

• add AnyTC to astNode converter. It's preparation for setDirectives() methods and printing added directives to SDL (for ApolloFederation support see #214). (8a5b1ce)
• EnumTypeComposer: add setDirectives(), setFieldDirectives() methods (69773ae)
• InputTypeComposer: add setDirectives(), setFieldDirectives() methods (81fab6c)
• InterfaceTypeComposer: add setDirectives(), setFieldDirectives(), setFieldArgDirectives() methods (726856c)
• ObjectTypeComposer: add setDirectives(), setFieldDirectives(), setFieldArgDirectives() methods (2f49d3f)
• ScalarTypeComposer: add setDirectives() method (a6a434e)
• UnionTypeComposer: add setDirectives() method (a386990)

Now graphql-compose supports Directive modification and printing them to SDL:

import { schemaComposer } from 'graphql-compose';

schemaComposer.createObjectTC(`type Location { city: String }`);
schemaComposer.createObjectTC(`type User { id Int location: Location }`);
UserTC.setDirectives([{ name: 'key', args: { fields: 'id } }]);
UserTC.setFieldDirectives([{ name: 'external' }]);

console.log(UserTC.toSDL({ deep: true }));  
// Will print something like:
// type User @key(fields: "id") { id: Int @external location: Location } 
// type Location { city: String }

Method toSDL({ deep: true }) will be very useful for Apollo Federation.
Before complete supporting of the Apollo Federation, It's required to implement resolver exports.
You may follow issue #214 for more details.
