+# stripSensitiveLiterals
+
+The `stripSensitiveLiterals` function is used to remove string and numeric
+literals from a graphql `DocumentNode` which could be sensitive. Consider using
+variables instead!
+
+## Usage
+
+```ts
+import { stripSensitiveLiterals } from "@apollo/utils.stripsensitiveliterals";
+
+stripSensitiveLiterals(
+  parse(`#graphql
+  query User {
+    user(name: "Ada Lovelace", age: 31, ids: ["1", "2", "3"]) 
+  }
+`),
+);
+/**
+  query User {
+    user(name: "", age: 0, ids: ["", "", ""]) 
+  }
+*/
+```
