SharedArrayBuffer error for davidobot.net examples on Chrome

[HTV04]

It seems that davidobot.net does not return the COOP and COEP response headers shown in the README, which throws this error unless love.js is running in compatibility mode:

Sending the response headers from the README fixes this error on my local server, so applying them to davidobot.net should fix this issue.

It's hosted on GitHub pages, but I might try this: https://github.com/gzuidhof/coi-serviceworker if I get a chance

I was able to get past this with the following.

Generate a web application from a LÖVE project in the current directory with the following steps:

• Enter npx love.js . web
• Press return to proceed.
• Enter a name for the game.
• This creates the directory web containing many generated files.

Create a web server that sets the appropriate HTTP headers to enable use of SharedArrayBuffer with the following steps:

• Install Node.js.
• Enter mkdir server
• Enter cd server
• Enter touch server.js

• Edit server.js and add the following code:

  const express = require('express');
  
  const app = express();
  
  app.use(express.static(
  '../web',
  {
    setHeaders: res => {
      res.set('Cross-Origin-Opener-Policy', 'same-origin');
      res.set('Cross-Origin-Embedder-Policy', 'require-corp');
    }
  }
  ));
  
  const PORT = 1919;
  app.listen(PORT, () => console.log('ready'));

Start the web server and run the game with the following steps:

• Enter node server.js
• Browse localhost:1919.

While this resolves the SharedArrayBuffer issue, it hit the new error below.

Try increasing the memory via the --memory flag.
