express-server-ping v1.0.0

Express Server Ping

Basic middleware that creates an endpoint to check if the server is running and it's ping.

Params

• Default param for Method is GET
• Default param for Path is /status

Install

$ npm install express-server-status

Usage

To use it with default settings

const serverStatus = require("express-server-ping");

//  create the endpoint on GET /status
app.use(serverStatus());

To use it on a custom path

const serverStatus = require("express-server-ping");

//  create the endpoint on GET /custom_endpoint
app.use(serverStatus({path:'/custom_endpoint'}));

Response

The created endpoint will send a response with a json like this {time: 000} where the value is the timestamp when the server received the request. So to check the ping you can do:

Code from examples/example.js

fetch('https://127.0.0.1/status').then(res => res.json()).then(data => {
    const now = Date.now();
    const roundtriptime = now - data.time;
    console.log(`Server is up | ${roundtriptime} ms`);
}).catch(ex => {
    console.log(`Server is down`);
}).finally(() => {
    server.close();
});
