encapsulate transform

The encapsulate transform allows you to easily encapsulate a specific schema into a single field under the root type.

For instance, if your handler created a schema like this, named mySchema:

Copy
type Query {
  something: String
}

type Mutation {
  doSomething: String
}
Copied to your clipboard
type Query {
  something: String
}

type Mutation {
  doSomething: String
}

The encapsulate transform will change your schema to this:

Copy
type Query {
  mySchema: mySchemaQuery!
}

type Mutation {
  mySchema: mySchemaMutation!
}

type mySchemaQuery {
  something: String
}

type mySchemaMutation {
  doSomething: String
}
Copied to your clipboard
type Query {
  mySchema: mySchemaQuery!
}

type Mutation {
  mySchema: mySchemaMutation!
}

type mySchemaQuery {
  something: String
}

type mySchemaMutation {
  doSomething: String
}

This transformer is useful when you have multiple APIs in your Mesh Gateway and you wish to have it wrapped with a name to better understand where each field is coming from.

Usage

The following example encapsulates the Adobe Commerce schema into the AdobeCommerce field:

Copy
{
  "meshConfig": {
    "sources": [
      {
        "name": "AdobeCommerce",
        "handler": {
          "graphql": {
            "endpoint": "https://venia.magento.com/graphql"
          }
        },
        "transforms": [
          {
            "encapsulate": {
              "applyTo": {
                "query": true,
                "mutation": false,
                "subscription": false
              }
            }
          }
        ]
      }
    ]
  }
}
Copied to your clipboard
{
  "meshConfig": {
    "sources": [
      {
        "name": "AdobeCommerce",
        "handler": {
          "graphql": {
            "endpoint": "https://venia.magento.com/graphql"
          }
        },
        "transforms": [
          {
            "encapsulate": {
              "applyTo": {
                "query": true,
                "mutation": false,
                "subscription": false
              }
            }
          }
        ]
      }
    ]
  }
}
