I have a simple NodeJS/express app running on an XT1144 (Boot Version: 8.0.94 | BrightSign OS Version: 8.5.47). I can browse to the IP address:port of the device from a PC on the same network and display the content for each endpoint (192.168.x.xxx:9090/endpoint). However, if I create a presentation with HTML5 widgets pointing to localhost:9090/test or /dashboard or /files, nothing is displayed on the device. I have the HTML5 widget sandwiched between two google.com in the presentation, so I know the device is displaying pages, just not from localhost.
index.js:
var express = require('express');
const fs = require('fs');
var app = express();
function main() {
//app.use(express.static('/storage/sd/node-server'));
app.get('/dashboard', function(req, res) {
console.log('GET: dashboard');
try{
res.sendFile('/storage/sd/node-server/dashboard.html');
}
catch(err){
console.log(err);
}
finally{
console.log('displayed dashboard');
}
})
app.get('/test', function(req, res) {
console.log('GET: test');
res.send('<h1>Hello, World!</h1>');
})
app.get('/files', function(req, res) {
const directoryPath = '/storage/sd/node-server';
fs.readdir(directoryPath, function(err, files) {
if (err) {
console.log('Error getting directory files:', err);
res.status(500).send('Error getting directory files');
} else {
res.send(files);
}
});
});
app.listen(9090, function() {
console.log('Example app listening on port 9090!');
});
}
// exchange below line to 'window.main = main;' if using node-server.html
// as the application entry point.
window.main = main();
Checking the logs for the unit, the device is hitting the express endpoints and receiving console.log output.
Log snippet:

Note that we are using BSNEE and BA 5, not Cloud/BA:Connected. I ran some tests with BA Connected and had no issues setting this up. Unfortunately, we cannot use it in our environment and must rely on BA 5.
