we use an webgl template to include an external javascript library and call those functions in jslib and interfaced in C#.
My concern is those Library/SDK needs to be served in an HTTP server to work.
Does Unity run an HTTP server to serve the HTML file during Unity in-editor play to simulate the page being hosted in an http/web server?
When you do a “Build And Run”, it runs a very simple local http server for running in the browser.
