topic Visual Studio Code and Webpack HMR (Hot Module Reload): Can It Work with ExB? in Experience Builder Custom Widgets https://community.esri.com/t5/experience-builder-custom-widgets/visual-studio-code-and-webpack-hmr-hot-module/m-p/1700794#M720 <P>I'm reaching the point of widget development where reloading and readding my custom widget for debugging is grinding my gears. The VSCode documentation suggests that webpack's HMR feature should just work for React, but they're using the default React toolchain, not whatever non-standard loadout the ExB team had to bolt together to get this all working. Has anyone had success getting HMR working? Is this even feasible with ExB's layout? In a perfect world I can hit save, wait for webpack to hot compile and then my next interaction with the debug browser instance pulls the hot-loaded code. At this point I'd settle for the hot-load only taking effect on remount.</P> Fri, 08 May 2026 03:40:31 GMT DavidSolari 2026-05-08T03:40:31Z Visual Studio Code and Webpack HMR (Hot Module Reload): Can It Work with ExB? https://community.esri.com/t5/experience-builder-custom-widgets/visual-studio-code-and-webpack-hmr-hot-module/m-p/1700794#M720 <P>I'm reaching the point of widget development where reloading and readding my custom widget for debugging is grinding my gears.

I click save in Visual Studio and click the refresh button in the browser and I see the changes. Isn't that what the Webpack hotloader does?</P> Fri, 08 May 2026 12:18:58 GMT https://community.esri.com/t5/experience-builder-custom-widgets/visual-studio-code-and-webpack-hmr-hot-module/m-p/1700851#M721 JeffreyThompson2 2026-05-08T12:18:58Z
