Installation

npm install server-diagnostic --save-dev

Usage

First, you have to import the library and create an instance of the ServerHub class:

const ServerHub = require("server-diagnostic");
// or import ServerHub from 'server-diagnostic';
const myHub = new ServerHub();

Class constructor

There are two optional parameters for the ServerHub constructor:

• useRestarter (boolean, default false)
• restartInterval (integer, default 10000) If useRestarter is set to false, you cannot specify a value for restartInterval. When useRestarter is enabled, the servers added to the hub will automatically restart if they crash every [restartInterval] milliseconds.

Add server method

This method will save a server to the hub you created. It has two parameters:

• url (string)
• filePath (string/null) Example:

const myHub = new ServerHub();
myHub.addServer("http://localhost:3000", "server.js");

const myHub = new ServerHub();
myHub.addServer("http://localhost:3000");

The server added must have a /testpath route or provide a response to every request. The ServerHub class will not test if the given server meets the requirements.

Remove server method

This is just the opposite of the addServer method. There is not a filePath parameter, just a URL parameter for removing a server.
Example:

myHub.addServer("http://localhost:3000", "server.js");
myHub.removeServer("http://localhost:3000");

Open diagnostic window method

This method will open a new tab in your default browser and updates the following diagnostics in real-time:

• The URL(italicized)
• Status(Online/Offline)
• Your ping to it

This method is simple enough, with the one parameter being the localhost port:

myHub.openDiagnosticWindow(3000);

Get servers method

This method will return an array of all of the servers currently stored in your hub:

const myHub = new ServerHub();

myHub.addServer("http://localhost:3000");
myHub.addServer("http://localhost:3001");

console.log(myHub.getServers);
