I am working on developing my ExpressJS app, and I have a specific requirement where I need the route to return a dynamically generated .js file that will be utilized by an html <script> tag. Can anyone provide guidance on how to accomplish this task effectively?
Just because you need the file on the client side doesn't mean it has to be stored on the server side as well. Create a route for the desired file and have the handler return the dynamically generated script.
router.get("/public/js/notafile.js", function(req, res) {
// This can be more than one line
res.send("function(){console.log('yey')}");
});
You can utilize a template, such as an underscore template or another type of file that replaces placeholders to create complex functions dynamically.
If you are serving a file that the client expects to be in your /public directory, ensure this is bound before your static binding. For example, place it before:
app.use(express.static(__dirname + '/public'));
