Executing express.js scripts from bootstrap front-end

Question

How would i go about runing some scripts i have written to be run on node server from my web application. I am still trying to figure out how to attach event listener from express app and any info or link to a great guide for that would be appreciated.

Anyway, back on question. Is it possible i have like a separate js file attached to my DOM with <link src=""> tag where i import my express scripts and i can execute from DOM using an onClick() attribute.

Answer 1

Use Post method, and your backend listen to data from frontend, and react accordingly.

No use <script src="" > not <link ref="" >, use in the html file.

Answer 2

thanks alot, with some jquery in the dom it was possible to attach an event listener and make the post request back the the express server. Thanks man Gordon

Answer 3

You are welcome, Antony O. Onyango

jQuery is heavy, long loading time.

You can use vanilla JavaScript

old syntax:

new syntax:
https://developer.mozilla.org/en-US/docs/Web/API/Fetch_API

The fetch specification differs from jQuery.ajax() in three main ways:

The Promise returned from fetch() won’t reject on HTTP error status even if the response is an HTTP 404 or 500.

Answer 4

Hi Antony, I think this code is kind of a suitable demonstration on how to use POST to send data to backend for generating content according, just in case you need an example for reference.
