Walkthrough

The beforeUnmount lifecycle hook in the chart core module was modified. The cleanup sequence was altered: now, this.integrateChart is set to null before attempting to call its uninstall method, which prevents the uninstall from being executed. The unwatching of reactive watchers remains unchanged.

Poem

A bunny hopped through code so neat,
Adjusted hooks, a tidy feat.
But uninstall slipped through the cracks,
Null came first, no turning back!
With whiskers twitching, lessons learned,
Next time, order is discerned.

Warning

There were issues while running some tools. Please review the errors and either fix the tool's configuration or disable the tool if it's a critical failure.

🔧 ESLint

If the error stems from missing dependencies, add them to the package.json file. For unrecoverable errors (e.g., due to private dependencies), disable the tool in the CodeRabbit configuration.

ESLint couldn't find the plugin "eslint-plugin-vue".

(The package "eslint-plugin-vue" was not found when loaded as a Node module from the directory "".)

It's likely that the plugin isn't installed correctly. Try reinstalling by running the following:

npm install eslint-plugin-vue@latest --save-dev

The plugin "eslint-plugin-vue" was referenced from the config file in ".eslintrc.js » @antfu/eslint-config » @antfu/eslint-config-vue".

⚠️ Potential issue

Critical bug: Setting integrateChart to null before calling uninstall method

The current code sets this.integrateChart = null before attempting to call this.integrateChart.uninstall(). This will cause a TypeError when trying to access the uninstall property on null, and the cleanup method will never execute, potentially causing the memory leakage issues mentioned in the PR objectives.

Apply this diff to fix the cleanup order:

-    this.integrateChart = null
-    if (this.integrateChart.uninstall) this.integrateChart.uninstall()
+    if (this.integrateChart && this.integrateChart.uninstall) {
+      this.integrateChart.uninstall()
+    }
+    this.integrateChart = null

In packages/vue/src/huicharts/huicharts-core/src/chart-core.ts at lines 582-583,
the code sets this.integrateChart to null before calling its uninstall method,
causing a TypeError. To fix this, first check if this.integrateChart and its
uninstall method exist, call uninstall if so, and only then set
this.integrateChart to null to ensure proper cleanup without errors.
