Answer 1

You can use express.static middleware

app.use('/public', express.static('directory/containing/your/files'));

The parameter of express.static is the path to the directory containing all your files that you wish to make static (the path that you provide can be relative to the directory where you launch your node process, or an absolute path), the directory should be available in your file system.
Then you can require your resources like: <img src='/public/imagesA.jpg'>
The '/public' mount path is optional, but recommended

Answer 2

in app.js you have to add static folder directory access

app.use(express.static(path.join(__dirname, 'public')));

in public folder add your folders files

--public
----javascript
----css
----img

inside javascript add your main.js

and in ejs add

<script src = "javascript/main.js"></script>
