Walkthrough

The changes update the BToast component's watcher to handle transitions of modelValue from a number to false, ensuring the countdown stops and the toast closes. The toast controller plugin's destroy method now uses the hide method to close the toast, replacing direct manipulation of the modelValue property. The BModal component adds a runtime check to safely access document.body to prevent errors during server-side rendering.

Changes

Files/Paths Change Summary
packages/bootstrap-vue-next/src/components/BToast/BToast.vue Enhanced watcher on modelValue to stop countdown when changing from number to false.
packages/bootstrap-vue-next/src/plugins/toastController/index.ts Updated destroy method to use hide() instead of directly setting modelValue = false.
packages/bootstrap-vue-next/src/components/BModal/BModal.vue Added runtime check for document before accessing document.body to prevent SSR errors.

Poem

A toast once lingered, stubborn to go,
But now with a number, then false, it will know—
To stop its countdown, and quietly hide,
With a hop and a skip, the bug’s brushed aside!
And modals now safely check the scene,
No more errors where docs aren't seen! 🥕✨

98-99: Consider passing an explicit trigger to hide()

Inside the destroy() method you now call this.hide() from nextTick.
While this works, omitting the trigger argument means downstream listeners cannot distinguish a normal hide operation from a destruction flow. Supplying a descriptive string (e.g. "destroy") preserves the intent and keeps the public event contract symmetric with other callers (hide('close'), etc.).

-              nextTick(() => {
-                this.hide()
+              nextTick(() => {
+                // Mark that this hide originates from destroy()
+                this.hide('destroy')
               })

246-267: Watch handler now covers number→false transition – looks correct

The added oldValue parameter and the extra guard (lines 259-266) cleanly stop the countdown when modelValue flips from a numeric timeout to false. Logic is sound and does not interfere with existing branches.
Minor style nit: typeof newValue === 'boolean' && newValue === false can be shortened to newValue === false without changing behaviour.

-  if (
-    typeof newValue === 'boolean' &&
-    newValue === false &&
+  if (
+    newValue === false &&
     typeof oldValue === 'number' &&
     oldValue > 0
   ) {
     stop()
   }

  • Ensure that 'this' correctly refers to the expected toast instance in this context. If there is any ambiguity, consider explicitly using the toast instance (e.g., toast.hide('destroy')).
this.hide('destroy')
