Dynamics 365 Portal - Best Practice for JavaScript

Posted on by Community Power Pla... Microsoft Employee

Hi All,

Thanks for reading my post.

We're doing configuration of 'Dynamics 365 Portal' for a client and we're bit confused where to maintain all of our JavaScript as per Best Practice?

At the moment, we have 3 viable options:-

Option # 1: Only one 'Custom.js' web file, which has all the JavaScript of the entire portal.
Option # 2: Couple of '*.js' web files which are based on following principle:
1. Core file - Contains functions that are used almost everywhere and other useful page things.
2. Module files - Contains code that is used in several places, but not everywhere.
Option # 3: Write down the JavaScript in the 'Custom JavaScript' field of the Entity form / Web form.

Which approach are you guys inclined to? Or what is the Best Practice for a JavaScript based on performance & maintainability?

Thanks for your time.

Hi

What I normally go for is a hybrid of your options #2.core and #3

My "core" JS contains common functions that I might use across the Portals
Then each Entity Form/Web Form/Web Page etc would have its own JS code, but normally calling whatever is generic from the core JS
The core JS can be a Web File or a Web Template, and you can reference it in your TrackingCode content snippet so it is available in every page
