Add ability to merge fields from types from different schemas
Adds transforms to wrap, extract, and rename fields, fixes #1183
Adds transform to filter object fields, fixes #819
Exports visitSchema, SchemaVisitor, healSchema, healTypes, cloneSchema, cloneType, cloneDirective to enable more custom transforms, fixes #1070

I really need #1200 please. My code is using wrapper types to handle values validation. And because of that, I cannot get my API correctly stitched.
Thanks for helping me out.

In the meantime you can use graphql-tools-fork.

https://www.npmjs.com/package/graphql-tools-fork

If you don't want to change your imports everywhere, an alias package can be used.

https://www.npmjs.com/package/module-alias

Hopefully this will be merged soon.

It looks like graphql-tools maintainers (apollo) don't want to accept any changes due to the deprecation of schema stitching. Their focus right now on Apollo Federation.

I hope not, because for my use case Apollo Federation is not an option. The services I am using can't support Apollo Federation specs right now.

I don't understand how they can deprecate schema stitching when federation hasn't even reached a version 1. Currently error handling with schema stitching is just completely broken for me, but there's no plan to fix this? Maybe we should make an official long term fork of graphql-tools?

Streamline mapper selection for types and directives.

Lays groundwork for additional SchemaMapper object formats, i.e. the resolver map format with specification of individual types/directives by name.
v12 does not support extensionASTNodes
v13 supports extensionASTNodes for query, mutation, and interface types
MapSchema actually can be used to rename scalars -- even to rename specified types -- because rewiring does not modify the original types (as opposed to healing).
Use interfaces over tpes whenever possible as per official TypeScript recommendation, so as to support declaration merging.

Separate delegation methods from stitching.
Rename folders to verbs when possible for consistency.
Rename transforms folder => wrap.
Move makeRemoteExecutableSchema to wrap folder, as it wraps a remote schema.
Use files property within package json to white-list files in straightforward fashion.
Do not publish extra markdown/images.
using mapSchema rather than visitSchema changes print(schema) order
now that fieldToFieldConfig has been removed, closes #44
move wrapping transforms into separate subfolder
move wrapping resolvers to wrap folder, was placed in old stitching folder because makeRemoteExecutableSchema was in stitching, but makeRemoteExecutableSchema now belongs in the wrap folder, an older method besides wrapSchema/transformSchema of wrapping a schema, specifically for remote schema.
and run prettier
 - adds TransformCompositeFields as generic transform that can function on fields belonging to objects and interfaces
 - refactoring TransformObjectFields to use TransformCompositeFIelds
  - adds TransformInterfaceFields along similar lines
  - adds RenameInterfaceFields and FilterInterfaceFields in parallel to RenameObjectFields and FilterObjectFields
  - make supporting types more generic and export them
  - add test for RenameInterfaceFields
already contained within transforms folder
BREAKING CHANGE:

Allow specification of args even with root field transformations. Includes changes to createRequestFromInfo and createRequest signatures and related interfaces, streamlining them to only use the targetOperation and targetFieldName, returning to the original upstream graphql-tools behavior of adding args later as a transform.

args passed to delegateToSchema, however, are still optional. All args passed to delegateToSchema are serialized using the targetSchema serialization, if available.
