Posted on by Syler42

Hello Community,

i have some expirience with power apps, but never worked with portals. Now I am trying to create a portal to see what possibilities the platfrom offers. I'm thinking about few cases, but is hard to find any information about it.

In case when i have a wepage wit large amount of javascript code:
1. It is posible to manage somhowe a project js files structure (fodlers, parents child hierachy etc.) or this files need to be saved in Web Files entity ?
2. It is possible to install js librarys from npm or i need manualy add correct files ?
3. There are any limitions abuout type o files that cannot be added as Web files ?

In case when i need to create complex UI:
4. It is possible to create custom controls/components and add this control to toolbars like Power Apps canvas apps components ?
5. When i need to create custom notfications, modals or wizards functionaly it is simpler, the same or harder than during normal web app development ?

And finaly general questiona about portals:
6. It is possible to have version history lik in power apps with ability to back to previous version ?
7. Could Power App portal be a port of solution like Canvas App. Does import/export between environment (Dev/Test/Prod) is possible in case of Power Apps Portals ?
8. It is possilbe to automate deploys between environments using AzureDev Ops ?

Thanks in advance

Hi, please see if below helps you:

I normally create a project under my source control with JS / Web Templates / Custom HTMLs etc.. you don't have to do it, it's optional, there is a tool in XrmToolBox to view/manage the code applied to your Portal as well, you can check that out - whatever method you chose, in the end, you always have to add your code into the Portal/CDS records

not directly, you need to either download/upload as a new Web File, or reference the online path for the library in your Portal code (usually Tracking Code content snippet or header/footer Web Template)

well.. by default you cannot upload a .JS file as attachment, that's a simple configuration on your CDS environment but that's not my recommendation. what I normally do is keep the .JS restricted and rename my file to a different extension (.ES or .MYJS) so you kind of trick CDS, but you can still reference your library in your Portals code

no (perhaps the answer is not yet).. Microsoft is working on enabling PCF controls in the Portals - most likely to be in Preview in December 2020, so that might be possible - but we are not entirely sure of how that's going to work.. what you can do is have your controls as a Web Template, and you can easily reference to a Web Template using the {% include %} tag, your Web Template can take input parameters and will basically contain HTML+Liquid+JS code

very similar to Web Development in my opinion, Portals comes with jQuery already loaded, so you can leverage that (if you are familiar with it) and build your HTML/Modals

not directly.. you can enable Audit for the CDS + Entities + Fields, and then you will have a history of any data changes - you need to be careful to only Audit what is necessary - there is another XrmToolBox tool that helps managing audit / rollback etc - my recommendation here would still have a source control separate and keep your code up to date there

Portal configuration is based on CDS data, you need to make sure you have the Portals provisioned in all environments, and then you can move the data across - again there is another XrmToolBox tool to move this data (also a few other methods)

I would recommend the session from Eugene a few weeks ago: https://www.365.training/Courses/Detail/Fall_PowerAppsPortals

Hi, there is an API available (in preview) for insert/update/delete operations on the CDS

I will share here a few articles, including the MS documentation:
