+# printWithReducedWhitespace
+
+Prints a GraphQL AST with a minimal amount of whitespace. Consider using the
+[`stripIgnoredCharacters`](https://github.com/graphql/graphql-js/blob/e9a81f2ba9020ec5fd0f67f5553ccabe392e95e8/src/utilities/stripIgnoredCharacters.ts) function from `graphql` instead of this function.
+
+## Usage
+
+```ts
+import { printWithReducedWhitespace } from "@apollo/utils.operationregistrysignature";
+
+const signature = operationRegistrySignature(
+  parse(`#graphql
+    query Foo {
+      bar
+    }
+  `),
+  "Foo",
+  { preserveStringAndNumericLiterals: true },
+);
+```
