+# graphql-fragments-manager
+
+`graphql-fragments-manager` helps with managing fragment dependencies when declaring graphql Queries, Mutations, Subscriptions
+
+## Example:
+
+```javascript
+import { buildFragment, includeFragments } from 'graphql-fragments-manager'
+
+const UserPhotoVersionFragment = buildFragment(
+  gql`
+    fragment UserPhotoVersionFragment on UserPhotoVersion {
+      width
+      height
+      version
+    }
+  `
+)
+
+const UserPhotoFragment = buildFragment(
+  gql`
+    fragment UserPhotoFragment on UserPhoto {
+      url
+      versions {
+        ...UserPhotoVersionFragment
+      }
+    }
+  `,
+  [UserPhotoVersionFragment]
+)
+
+const UserFragment = buildFragment(
+  gql`
+    fragment UserFragment on User {
+      id
+      photo {
+        ...UserPhotoFragment
+      }
+    }
+  `,
+  [UserPhotoFragment]
+)
+
+const QUERY = gql`
+  query UserQuery($id: ID!) {
+    user(id: $id) {
+      ...UserFragment
+    }
+  }
+
+  ${includeFragments(UserFragment)}
+`
+
+/// INSTEAD OF:
+
+const QUERY = gql`
+  query UserQuery($id: ID!) {
+    user(id: $id) {
+      ...UserFragment
+    }
+  }
+
+  ${UserFragment}
+  ${UserPhotoFragment}
+  ${UserPhotoVersionFragment}
+`
+```
+
+`includeFragments` function will gather dependencies on all included fragments and will include all necessary fragments that are necessary for graphql. This helps avoid runtime errors when fragments are complex, with many nested fragments.
