Use NoPE in Programms

Optional: Create a Project:​

To create a project folder with NoPE checkout our tutorial, otherwise ensure the NoPE-Package is installed:

npm install nope-js-node

The Dispatcher:​

To implement the functionalities of NoPE, NoPE creates so called runtime environments. Inside of such a environment the system uses a so-called 'NoPE dispatcher' as a central element.

The NoPE dispatcher is designed as a layer between the different modules and other runtimes (these might exist based on the distribution of the system). The dispatcher enables distributed computing and creates simply micro kernel architecture. A dispatcher is used to connect the modules, share data and events and provide a remote procedure call (rpc) interface.

Create a Dispatcher​

To start exploring the capabilities of the dispatcher we will firstly create a Dispatcher. Please checkout the getDispatcher-function in basics sample to get some informations about the valid parameters.

// First lets import nope.
import * as nope from "nope-js-node";

// Lets create our dispatcher
const dispatcher = nope.dispatcher.getDispatcher({
  communicator: nope.getLayer("event"),
});

Wait for the Dispatcher​

Because the entire Library is written async, we must wait until the sytem is ready: 

// To wait until the Sytem is ready, we 
// can  use the ready Oberservable of the 
// dispatcher.
await dispatcher.ready.waitFor()

if we are not running the code above in an async method we will use the .then option:

// To wait until the Sytem is ready, we 
// can  use the ready Oberservable of the 
// dispatcher.
dispatcher.ready.waitFor().then(_ => {
  // Do your stuff.
}).catch(e => {
  // Handle the error
});
Congratulations

You are now running a distributed System inside your programm
