Minor Changes

• #180 a208f1c Thanks @n1ru4l! - Add composeSchemaContract function for composing schema contracts.

  Running the following script:

  import { composeSchemaContract } from "@theguild/federation-composition";
  import { parse } from "graphql";
  
  const result = composeSchemaContract(
    [
      {
        name: "a",
        typeDefs: parse(/* GraphQL */ `
          type Query {
            a: String @tag(name: "public")
          }
        `),
        url: "a.localhost",
      },
      {
        name: "b",
        typeDefs: parse(/* GraphQL */ `
          type Query {
            b: String
          }
        `),
        url: "b.localhost",
      },
    ],
    /** Tags to include and exclude */
    {
      include: new Set(["public"]),
      exclude: new Set(),
    },
    /** Exclude unreachable types */
    true,
  );
  
  console.log(result.publicSdl);

  Will result in the output containing only the fields tagged with public:

  type Query {
    a: String!
  }
