This PR updates the auto reload to fully reload both the UI and server source code when any change is detected in the watched autoreload files.
Previously, auto reload would trigger a refresh of the app but the UI or server functions would be updated only if the
ui.Rorserver.Rfiles themselves changed (or both if using a single-file app source).This PR updates auto reloading so that any change to the files matching
shiny.autoreload.patterncauses both the UI and server source to be reloaded.This fixes two long-standing open issues:
Fixes #2711
Fixes #1142
Example app
For testing, the following app sources R files and uses stylesheets outside the main
app.R. Currently, inmain, any changes to the supporting files causes the app to be reloaded but the reloaded app does not reflect the changes.After this PR, changes to support files are reflected after the reload.
Example app on shinylive.
