### Minor Changes

- [#444](https://github.com/graphql-hive/gateway/pull/444) [`b52c9ba`](https://github.com/graphql-hive/gateway/commit/b52c9ba47f84d0905f1f63fdfe071c891dce5b7f) Thanks [@ardatan](https://github.com/ardatan)! - Now `SupergraphSchemaManager` can be used in `ApolloServer` as `gateway`;

  ```ts
  import { ApolloServer } from '@apollo/server';
  import { SupergraphSchemaManager } from '@graphql-tools/federation';

  const gateway = new SupergraphSchemaManager();
  const apolloServer = new ApolloServer({
    gateway,
  });
  ```

  And with the new `onStitchedSchema` option, you can manipulate the executable schema created from the supergraph.
  The following example demonstrates how to use `onStitchedSchema` with `applyMiddleware` from `graphql-middleware`:

  ```ts
  import { SupergraphSchemaManager } from '@graphql-tools/federation';
  import { applyMiddleware } from 'graphql-middleware';

  const logInput = async (resolve, root, args, context, info) => {
    console.log(`1. logInput: ${JSON.stringify(args)}`);
    const result = await resolve(root, args, context, info);
    console.log(`5. logInput`);
    return result;
  };

  const logResult = async (resolve, root, args, context, info) => {
    console.log(`2. logResult`);
    const result = await resolve(root, args, context, info);
    console.log(`4. logResult: ${JSON.stringify(result)}`);
    return result;
  };

  const gateway = new SupergraphSchemaManager({
    onStitchedSchema: async (schema) => {
      // Manipulate the schema
      return applyMiddleware(schema, logInput, logResult);
    },
  });
  ```

### Major Changes

- [#308](https://github.com/graphql-hive/gateway/pull/308) [`d747d4c`](https://github.com/graphql-hive/gateway/commit/d747d4cd37317e8a9b2b95a5270c0fbd47e4cba3) Thanks [@ardatan](https://github.com/ardatan)! - BREAKING CHANGES;

  - Removed `buildSubgraphSchema`, use `@apollo/subgraph` instead.
  - Removed the following gateway related functions, and prefer using Supergraph approach instead
    - `getSubschemaForFederationWithURL`
    - `getSubschemaForFederationWithTypeDefs`
    - `getSubschemaForFederationWithExecutor`
    - `getSubschemaForFederationWithSchema`
    - `federationSubschemaTransformer`
  - `SupergraphSchemaManager` is no longer an `EventEmitter` but `EventTarget` instead, and it emits a real `Event` object.
  - `SupergraphSchemaManager` is now `Disposable` and it no longer stops based on Nodejs terminate events, so you should use `using` syntax.

  ```ts
  using manager = new SupergraphSchemaManager({ ... });

  manager.addEventListener('error', (event: SupergraphSchemaManagerErrorEvent) => {
    console.error(event.detail.error);
  });

  let schema: GraphQLSchema | null = null;
  manager.addEventListener('schema', (event: SupergraphSchemaManagerSchemaEvent) => {
      schema = event.detail.schema;
  });
  ```

  When a selection set for a computed field needs to be merged, resolve that required selection set

  field in the `Post` type is merged with the selection set for the `authorId` field in the
  `Comment` type.

  ```graphql

  is a computed field requires another computed field requires a field from the initial subschema.

  In the following test case, `totalOrdersPrices` needs `userOrders` which needs `lastName` from
  initial `Query.user`. So the bug was skipping the dependencies of `userOrders` because it assumed
  `lastName` already there by mistake.

  maybe).

  [`7368829`](https://github.com/ardatan/graphql-tools/commit/73688291af0c8cb2fe550fe8c74fd8af84cb360f)
  Thanks [@ardatan](https://github.com/ardatan)! - Handle interface objects in a different way

  Thanks [@ardatan](https://github.com/ardatan)! - Handle interface types with non-shared
  implementations;

  For example, you have the following services, where `Node` is implemented in both services, but
  `Foo` and `Bar` are only implemented in one service. And when the gateway receives the following
  query, it should be converted to this because `Node` is not implemented as `Bar` in Service 1
  while implemented in Service 2.

  Query conversion;

  ```graphql
  # Gateway request
  query {
    fooBar(id: "1") {
      ... on Node {
        id
      }
    }
  }
  ```

  ```graphql
  # Service 1 Request
  query {
    fooBar(id: "1") {
      ... on Foo {
        id
      }
      ... on Bar {
        id
      }
    }
  }
  ```

  Services;

  ```graphql
  # Service 1

  union FooBar = Foo | Bar

  interface Node {
    id: ID!
  }

  type Foo implements Node {
    id: ID!
  }

  type Bar {
    id: ID!
  }

  type Query {
    fooBar(id: ID!): FooBar
  }
  ```

  ```graphql
  # Service 2
  interface Node {
    id: ID!
  }

  type Foo implements Node {
    id: ID!
  }

  type Bar implements Node {
    id: ID!
  }
  ```
