Bablyonjs & express

[Spankied]

How do I setup express server with bablyon? Any demo repos?

Perhaps this isnt feasible. If so, what are my options for dynamically serving bablyon scenes? 

The goal is to design scenes, then run them on schedule.

Babylon is a frontend framework (thou deltakosh just released the nullEngine for server-side usage, but I don't think this is what you wanted).

You need to simply serve the js and .babylon scenes (or whatever format you want to use), and produce an html file for your visitors.

I'm building something similar at the moment. Here's the basic setup:

import express from 'express';
import { json, urlencoded } from 'body-parser';
import cors from 'cors';

const app = express();

// this allows us to accept big JSON objects via POST request:
app.use(json({
  limit: '50mb',
  parameterLimit: 1000000
}));

app.use(urlencoded({
  extended: true,
  limit: '50mb',
  parameterLimit: 1000000
}));

app.use(cors({ origin: '*' })); // this is optional, but I need it for my specific setup

app.use('/', express.static('public')); // I'm serving static html/js/css here, which renders the bjs scene

app.post('/scene', async (req, res) => {
  // in your front-end JS, do the following:
  // 1. Serialize your scene. ex: let sceneAsJSON = BABYLON.SceneSerializer.Serialize(scene);
  // 2. make a POST request to 'http://[host ip:port]/scene' that includes the serialized JSON you created in step #1 in the body of the request.
  // 
  // That JSON object (your serialized scene) will show up here in req.body.[your post variable name]. Now you can do whatever you want with it—save to a database, cram it in a .babylon file, etc.

  // don't forget something to reply to the browser's request
  res.json({ whatever: 'bacon' });
});

app.listen(3000, function () {
  console.log('app is listening on port 3000.');
});

Thanks fort, this gives me an idea of things would work.
