Converting Flex Viewer app's to JavaScript

[ChadKopplin]

Based on Esri's posting about not supporting the Flex and Windows Silverlight api's beyond the current version, I am in the process of converting our current Flex Viewer applications to JavaScript, I will be taking JavaScript training, but I am wondering how easy it will be to convert my current applications with their functionality to JavaScript?  Thank you for your comments and ideas in advance.  Here are the links to a couple of our more widely used app's to let you know what I have.

DEQ-LQD Flex Application

DEQ-VRP Flex Application

DEQ-WATER/WASTEWATER Flex Application

Chad,

The Web AppBuilder Developers Edition (WAB) is probably you best bet to get started.  There are many resources on GeoNet to help, and many users have started creating custom widgets to help us all out. Join and start following  Web AppBuilder for ArcGIS​ and Web AppBuilder Custom Widgets​ and ArcGIS API for JavaScript

and check out (my blog) the following to help you get started

Tips and Observations for getting Web AppBuilder -  Developer Edition Installed​

Web AppBuilder Developer Edition – Customization Resource List​

WAB does require access to ArcGIS Online or a Portal account to get started....if you prefer to avoid that, the Javascript API is the place to start with the many samples available.  ArcGIS API for JavaScript

Hope this helps to get you started.

Thank you, I have been looking into the new Web appbuilder and the API, and was not sure if that was the best route or not.  Great info.  I will be checking out the blog, thank you.
