Schema stitching in graphql-mesh

[jmargieh]

Hello,

We currently use @graphql-tools/stitch to merge schemas and we would like to achieve the same thing using graphql-mesh

Currently we do that using:

    const coreSchema: any = await introspectSchema(coreExecutor, {});
    const runtimeSchema: any = await introspectSchema(runtimeExecutor, {});
    return stitchSchemas({
      subschemas: [
        {
          schema: coreSchema,
          executor: coreExecutor,
          merge: {
            Page: {
              fieldName: 'Page',
              args: originalObject => ({ Id: originalObject.Id, visualIds: getVisualIdsFromContent(originalObject.Contents) })
            }
          }
        },
        {
          schema: runtimeSchema,
          executor: runtimeExecutor,
          merge: {
            WorkPage: {
              fieldName: 'Page',
              args: originalObject => ({ ...originalObject })
            },
          }
        }
      ]
    });

How this line: args: originalObject => ({ Id: originalObject.Id, visualIds: getVisualIdsFromContent(originalObject.Contents) })
can be achieved using the typeMerging aproach?

I also see that this code https://github.com/Urigo/graphql-mesh/blob/master/packages/transforms/type-merging/src/index.ts#L19 was commented out even though it i part of the mesh Docs here: https://www.graphql-mesh.com/docs/handlers/graphql#config-api-reference
