readme.md

Check out https://github.com/newagesoftwareLLC/Node_Message_Server if you want to use WebSocket to notify all web app users that there's new data available and to update or add this new data to a DOM element.

node_express_post.js

// Post data to `http://(host):(port)/handle` in JSON format.
var express = require("express");
//var WebSocket = require('ws');
//var sqlite3 = require("sqlite3").verbose();
var app = express();

app.use(express.json());
app.use(express.urlencoded({ extended: true }))

// Can change path to '/node/api/handle' to support iisnode. 
// If you do, then navigation would be http://(host):(port)/api/handle
app.post('/handle',(req,res) => {
    console.log(req.body);
    // websocket example if you want to let other web apps know new data has come through
    /*var ws = new WebSocket('ws://localhost:9898/inspection');
    ws.on('open', function open() {
        ws.send(JSON.stringify(req.body));
        console.log("ws data sent.");
    });*/
    // store post data into an SQLite database file
    /*let db = new sqlite3.Database("db.db", (err) => {
        if (err) {
            console.error(err.message); // this will stop execution of code block
        } else {
            db.run("INSERT INTO inspection (title, message) VALUES (?, ?)", [req.body.title, req.body.message, function (err, result) {

    console.log("Started on PORT " + process.env.PORT);
