module.exports={
  movies:files

app.js file

import { movies } from "./server/server.js";
console.log(movies);

Answer 1

You can't do it. app.js in client, It can't import "./server/server.js" But you can send array has name of file in that forder when render.

node.js :

const files=fs.readdirSync('../Movies');
// when user request your page (this example use ejs)
res.render('<your_ejs_file>', {
    myFiles: files,
});
// in your_ejs_file, create variable:
<script>
    var yourFiles = <%= JSON.stringify(myFiles)%>            
</script>

yourFiles is array named of file in your_folder If you want load file from server, you can use AJAX to load it.

I use name of variable diffrent to you avoid mistake them.

If you want to send data from server-side to the client-side, you can use AJAX (sending HTTP requests to the server using front-end JavaScript). There are also other useful packages that you can use to simplify your work, like request or axios
