Link

A design-time dependency between two components in a blueprint.

A link declares that one component's output should be wired into another component's input. For example, a link from a database component's authentication output to an application component's database input ensures the app receives the database connection string.

At deploy time, each link is realized as a connection in the environment, wiring the actual instance outputs to instance inputs.

type Link {
  id: ID!
  fromField: String!
  toField: String!
  createdAt: DateTime!
  updatedAt: DateTime!
  fromComponent: Component
  toComponent: Component
}

Fields

Link.id ● ID! non-null scalar {#id}

Link.fromField ● String! non-null scalar {#from-field}

The output field name on the source component (e.g., authentication).

Link.toField ● String! non-null scalar {#to-field}

The input field name on the destination component (e.g., database).

Link.createdAt ● DateTime! non-null scalar {#created-at}

When this link was created (UTC).

Link.updatedAt ● DateTime! non-null scalar {#updated-at}

When this link was last modified (UTC).

Link.fromComponent ● Component object {#from-component}

The source component that produces the output.

Link.toComponent ● Component object {#to-component}

The destination component that consumes the input.
