Short examples
The main Moleculer repository contains some examples.
To try them, at first, you should clone the Moleculer repo with the following command:
git clone https://github.com/moleculerjs/moleculer.git
Simple
This is a simple demo with a Math service which can add, sub, mult and divide two numbers.
$ npm run demo simple |
Source code is available on Github
Server & client nodes
In this example, you can start any servers & clients. The servers serve the math.add action and clients call it in a loop. You can start multiple instances from both.
They use TCP transporter, but you can change it with TRANSPORTER env variable.
Start a server
$ node examples/client-server/server |
Start a client
$ node examples/client-server/client |
Source code is available on Github
Middlewares
This example demonstrates how the middleware system works.
$ npm run demo middlewares |
Source code is available on Github
Runner
This example shows how you can start a broker and load services with Moleculer Runner
$ node ./bin/moleculer-runner.js -c examples/runner/moleculer.config.js -r examples/user.service.js |
It starts a broker with options from moleculer.config.js, loads the user service from user.service.js file and switch to REPL mode.

Load tester
With this example, you can start a load test. The server & client prints how many requests executed in a second.
Start server
$ node examples/loadtest/server |
Start & fork clients (number of CPU cores)
$ node examples/loadtest/clients |
