I am trying to develop a traditional web part (SP2013, SP2010..) to host a modern SPFx client web part. I developed most of the plumbing and wrapping and I have some problems when actually render the client side web part on the screen.

First question: does anyone tried something like that before? Any help / hint could be given? (the reason to develop this is to make the on premise / old environments ready for migration to O365, so the solution could be develop in the latest and greatest)

Second question: Does anyone know the internals of the sp-client-base.js script? I am trying to load all necessary script for the client web part to load, but I have the following exception here:

Uncaught TypeError: Cannot read property 'SPFlight' of undefined

 var H = r(21);
 t.SPFlight = H.SPFlight,
 t.UrlQueryParameterCollection = H.UrlQueryParameterCollection,

I am trying to load the scripts required by the bundled version of the client side web part:

        paths: {

Consider following interesting webcast from PnP team:
Using modern web stack with SharePoint on-premises deployments

They are also created project on github demonstrating approach:

With this approach you can later more smoothly move to SPFx.

  • Thanks for the info! I already used this to create full web stack solutions on premise (in react and angular), but I would like to integrate the SPFx ones. So, the same code base to work on both. Just to upload the spfx package file, copy the bundles somewhere and done. I am trying now to reverse engineer the workbench to try to implement it. Dec 29, 2016 at 12:31
  • Now I see... That's really interesting and cool. If you will be able to do this, please ping me :) Dec 29, 2016 at 12:35

At this point in time, SPFX is only available in O365. The plan is to port it to on-prem after it hits General Availability in the service and we have time to iron out any issues that crop up.
