+# dropUnusedDefinitions
+
+Given an operation document and an operation name, this function will return a
+new document with only the definitions required for the operation name provided.
+
+If the provided operation name doesn't match any operation in the document,
+`dropUnusedDefinitions` will return the original document.
+
+## Usage
+
+```ts
+import { dropUnusedDefinitions } from "@apollo/utils.dropunuseddefinitions";
+
+const operation = parse(`#graphql
+  query Drop { ...DroppedFragment }
+  fragment DroppedFragment on Query { abc }
+  query Keep { ...KeptFragment }
+  fragment KeptFragment on Query { def }
+`);
+const keepOperation = dropUnusedDefinitions(operation, "Keep");
+/**
+query Keep {
+  ...KeptFragment
+}
+
+fragment KeptFragment on Query {
+  def
+}
+*/
+```
