+## Reading List Application
+
+### Developed a Simple Reading list Application using `AngularV6` + `ApolloClient` as FrontEnd and `NodeJs` + `Express` + `GraphQL` + `MongoDB` as Backend
+
+#### Functionalities:
+
+* Get Books List using GraphQL Query
+* Add Book
+* Add Author
+* Get Book - which return the book details and authors detail and similar books return by this author.
+
+
+#### GraphQL Queries:
+
+* GraphQL Query for **getBook** 
+
+  ```
+  query($id: ID) {
+    book(id: $id) {
+        id 
+        name 
+        genre 
+        author { 
+            id 
+            name 
+            age 
+            books { 
+                id 
+                name 
+                genre 
+            } 
+        } 
+    } 
+  }
+  ```
+
+#### Folder Details:
+
+* Server -> Server Folder is nothing but backend `NodeJS + Express` Application, and used `GraphQL` for Querying the data from the `MongoDB` Database.
+* Client -> Client folder is Angular6 Front end Application
+
+
+
+#### Installation:
+
+* run `npm install` inside both **client** and **server** folders
+
+* run `ng build -prod` inside the client directory to build the Angular application and build files will be saved into the `server/public` directory. 
+
+* After that run ```node app.js``` inside the server folder to run the node application.
