97
+There are a many things you can hook into to manage your connections
49 98
 
50
-rpclibrary offers a special type of call that can be used with callbacks. The callback **has to be the last argument** and **may be the only passed function**. 
99
+```typescript
100
+new RPCServer(20001, [{
101
+    name: 'MyRPCGroup1',
102
+    exportRPCs: () => [
103

104
+        add,
105
+        getAsync,
106
+        {
107
+            name: 'getCallback',
108
+            hook: getCallback,
109
+            onClose: (response, rpc) => { /* client disconnected */ },
110
+            onCallback: (...callbackArgs) => { /* callback triggered */ }
111
+        }
112
+    ],
113
+}], {
114
+    visibility: '127.0.0.1', //0.0.0.0
115
+    closeHandler: (socket) => { /* global close handler */ },
116
+    connectionHandler: (socket) => { /* new connection made */ },
117
+    errorHandler: (socket, error, rpcname, argArr) => { /* An error occured inside a RPC */ },
118
+})
51 119
 
52
-In order to function, some metadata has to be included in the return value of hooks. On success, the function is expected to return a `{ result: 'Success', uuid: string }` (Types.SubscriptionResponse) or in case of errors a `{ result: 'Error' }`(Types.ErrorResponse).
120
+const sock = new RPCSocket(20001, 'localhost')
121
+sock.on('error', (e) => { /* handle error */ })
122
+sock.on('close', () => { /* handle close event */ })
53 123
 
54
-The uuid, as the name implies, is used to uniquely identify the callback for a given invocation and also dictates the name given to the client-side RPC. Unless you got a preferred way of generating these (e.g. using some kind of unique information important to your task) we recommend [uuid](https://www.npmjs.com/package/uuid) for this purpose. 
124
+sock.hook('RPCName', (/* arg0, arg1, ..., argN */) => { /* bind client-side RPCs */ }) 
125
+//Retrieve the socket from connectionHandler (Server-side) and trigger with 
126
+//socket.call('RPCName', arg0, arg1, ..., argN)
55 127
 
56
-You should unhook the client socket once you're done with it as not to cause security or control flow issues.

180
+rpclibrary is a typescript-first project and offers full support for typing your RPCs.
181
+**NOTE** that your function implementations have to be currectly typed to make the compiler agree. 
182
+Explicit typing is recommended.
183
+
184
+Example:
185
+```typescript
186
+echo = (x) => x
187
+    /*becomes*/
188
+echo = (x:string) : string => x

-#Experimental typing support
118
-It is possible to declare pseudo-interfaces for servers and clients by using server's second generic parameter.
119
-This feature is currently still in development and considered **unstable and untested**. Use with caution.
239
+
240
+# A class-based scalable pattern for APIs
241
+
242
+because long lists of functions quickly become unwieldy, it is smart to break up the RPCs into chunks or features.
243
+A pattern I found to be useful is as follows:
120 244
 
121 245
 ```typescript
122
-type MyInterface = { 
123
-    Group1: { 
124
-        triggerCallbacks: (...args:any[]) => Promise<void>,
125
-        subscribe: (param:string, callback:Function) => Promise<SubscriptionResponse<{a: string}>>,
126
-        unsubscribe: (uuid:string) => Promise<void>
127
-    },
128
-    Group2: {
129
-        echo: (x:string) => Promise<string>
246
+interface IMyImplementation {
247
+    echo: (x: string) => string
248
+    add: (a: number, b: number) => number
249
+    getAsync: () => Promise<{ topic: string, message: string }>
250
+    getCallback: (callback:Function) => string
251
+}
252
+
253
+type MyInterface = {
254
+    MyRPCGroup1: {
255
+        echo: IMyImplementation['echo']
256
+        add: IMyImplementation['add']
257
+        getAsync: IMyImplementation['getAsync']
258
+        getCallback: IMyImplementation['getCallback']
130 259
