+# Interceptor
+
+Node gRPC provides simple APIs to implement and install interceptors on clients
+and servers. An interceptor intercepts the execution of each incoming/outgoing
+RPC call on the client or server where it is installed. Users can use
+interceptors to do logging, authentication/authorization, metrics collection,
+and many other functions that can be shared across RPCs.
+
+## Run the server
+
+```
+node server.js
+```
+
+## Run the client
+
+```
+node client.js
+```
+
+# Explanation
+
+In Node gRPC, clients and servers each have their own types of interceptors.
+
+## Client
+
+Node gRPC client interceptors are formally specified in [gRFC L5](https://github.com/grpc/proposal/blob/master/L5-node-client-interceptors.md).
+An interceptor is a function that can wrap a call object with an
+`InterceptingCall`, with intercepting functions for individual call operations.
+To illustrate, the following is a trivial interceptor with all interception
+methods:
+
+```js
+const interceptor = function(options, nextCall) {
+  const requester = {
+    start: function(metadata, listener, next) {
+      const listener = {
+          onReceiveMetadata: function(metadata, next) {
+            next(metadata);
+          },
+          onReceiveMessage: function(message, next) {
+            next(message);
+          },
+          onReceiveStatus: function(status, next) {
+            next(status);
+          }
+      };
+      next(metadata, listener);
+    },
+    sendMessage: function(message, next) {
+      next(messasge);
+    },
+    halfClose: function(next) {
+      next();
+    },
+    cancel: function(message, next) {
+      next();
+    }
+  };
+  return new InterceptingCall(nextCall(options), requester);
+};
+```
+
+The requester intercepts outgoing operations, and the listener intercepts
+incoming operations. Each intercepting method can read or modify the data for
+that operation before passing it along to the `next` callback.
+
+The `RequesterBuilder` and `ListenerBuilder` utility classes provide an
+alternative way to construct requester and listener objects
+
+## Server
+
+Node gRPC server interceptors are formally specified in [gRFC L112](https://github.com/grpc/proposal/blob/master/L112-node-server-interceptors.md).
+Similar to client interceptors, a server interceptor is a function that can
+wrap a call object with a `ServerInterceptingCall`, with intercepting functions
+for individual call operations. Server intercepting functions broadly mirror
+the client intercepting functions, with sending and receiving switched. To
+illustrate, the following is a trivial server interceptor with all interception
+methods:
+
+```js
+const interceptor = function(methodDescriptor, call) {
+  const responder = {
+    start: function(next) {
+      const listener = {
+        onReceiveMetadata: function(metadata, next) {
+          next(metadata);
+        },
+        onReceiveMessage: function(message, next) {
+          next(message);
+        },
+        onReceiveHalfClose: function(next) {
+          next();
+        },
+        onCancel: function() {
+        }
+      };
+      next(listener);
+    },
+    sendMetadata: function(metadata, next) {
+      next(metadata);
+    },
+    sendMessage: function(message, next) {
+      next(message);
+    },
+    sendStatus: function(status, next) {
+      next(status);
+    }
+  };
+  return new ServerInterceptingCall(call, responder);
+}
+```
+
+As with client interceptors, the responder intercepts outgoing operations and
+the listener intercepts incoming operations. Each intercepting method can read
+or modify the data for that operation before passing it along to the `next`
+callback.
+
+The `ResponderBuilder` and `ServerListenerBuilder` utility classes provide an
+alternative way to build responder and server listener objects.
