## Usage
|
|
We recommend the use of TypeScript.
|
|
Under the hood we use socket.io and shortid for managed data exchange.
|
|
|
|
### Serverside
|
|
```typescript
|
|
import * as smartsocket from "smartsocket";
|
|
import * as q from q // q is a promise library
|
|
|
|
// The "Smartsocket" listens on a port and can receive new "SocketConnection" requests.
|
|
let mySmartsocket = new smartsocket.Smartsocket({
|
|
port: 3000 // the port smartsocket will listen on
|
|
});
|
|
|
|
// A "SocketRole" can be referenced by "SocketFunction"s.
|
|
// All "SocketRequest"s carry authentication data for a specific "SocketRole".
|
|
// "SocketFunction"s know which "SocketRole"s are allowed to execute them
|
|
let mySocketRole = new smartsocket.SocketRole({
|
|
name: "someRoleName",
|
|
passwordHash: "someHashedString"
|
|
});
|
|
|
|
// A "SocketFunction" executes a referenced function and passes in any data of the corresponding "SocketRequest".
|
|
// The referenced function must return a promise and resolve with data of type any.
|
|
// Any "SocketRequest" carries a unique identifier. If the referenced function's promise resolved any passed on argument will be returned to the requesting party
|
|
let testSocketFunction1 = new smartsocket.SocketFunction({
|
|
funcName:"testSocketFunction1",
|
|
funcDef:(data) => {
|
|
console.log('testSocketFunction1 executed successfully!')
|
|
},
|
|
allowedRoles:[mySocketRole] // all roles that have access to a specific function
|
|
});
|
|
|
|
// A "Smartsocket" exposes a .clientCall() that gets
|
|
// 1. the name of the "SocketFunction" on the client side
|
|
// 2. the data to pass in
|
|
// 3. And a target "SocketConnection" (there can be multiple connections at once)
|
|
// any unique id association is done internally
|
|
mySmartsocket.clientCall("restart",data,someTargetConnection)
|
|
.then((responseData) => {
|
|
|
|
});
|
|
```
|
|
|
|
#### Client side
|
|
```typescript
|
|
import * as smartsocket from "smartsocket";
|
|
|
|
// A "SmartsocketClient" is different from a "Smartsocket" in that it doesn't expose any public address.
|
|
// Thus any new "SocketConnection"s must be innitiated from a "SmartsocketClient".
|
|
let testSmartsocketClient = new smartsocket.SmartsocketClient({
|
|
port: testConfig.port,
|
|
url: "http://localhost",
|
|
password: "testPassword",
|
|
alias: "testClient1",
|
|
role: "testRole1"
|
|
});
|
|
|
|
// You can .connect() and .disconnect() from a "Smartsocket"
|
|
testSmartsocketClient.connect()
|
|
.then(() => {
|
|
done();
|
|
});
|
|
|
|
// The client can also specify "SocketFunction"s. It can also specify "SocketRole"s in case a client connects to multiple servers at once
|
|
let testSocketFunction2 = new smartsocket.SocketFunction({
|
|
funcName: "testSocketFunction2",
|
|
funcDef: (data) => {}, // the function to execute, has to return promise
|
|
allowedRoles:[]
|
|
});
|
|
|
|
|
|
// A "SmartsocketClient" can call functions on the serverside using .serverCall() analog to the "Smartsocket"'s .clientCall method.
|
|
mySmartsocketClient.serverCall("function",functionCallData)
|
|
.then((functionResponseData) => { // the functionResponseData comes from the server... awesome, right?
|
|
|
|
});;
|
|
```
|
|
|
|
> **NOTE:**
|
|
you can easily chain dependent requests on either the server or client side with promises.
|
|
`data` is always a js object that you can design for your specific needs.
|
|
It supports buffers for large binary data network exchange. |
