Answer 1

For me, If i would like to put videos for online download, I would use Node.js to set public folder, all video files can be uploaded in public folder for download.

I use express.js

Code is simply to set public asset folder:

const express = require ("express");
const app = express();

app.use(express.static("public")); // set public asset in public folder
app.get("/", (req, res)=>{
res.render(index); // you could set all the download path from index.html
});

const port = process.env.PORT && 3000;
app.listen(port, ()=>console.log("App listening to port " + port);
// access index.html by localhost:3000 if test on local
