Executing express.js scripts from bootstrap front-end

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.

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.

You are welcome, Antony O. Onyango jQuery is heavy, long loading time. You can use vanilla JavaScript old syntax: https://developer.mozilla.org/en-US/docs/Web/API/XMLHttpRequest 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.

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. https://code.sololearn.com/W9d2cR0D6P77/?ref=app
