## Status
|
|
|
|
Accepted
|
|
|
|
## Context
|
|
|
|
- The js resources are disposed at the end of js lifecycle
|
|
- Current listener in used is `beforeunload`. However, `beforeunload` was unstable, resulting in memory leak.
|
|
|
|
## Decision
|
|
|
|
- `beforeunload` was replaced by `pagehide`, which is more reliable.
|
|
- [`pagehide` documentation](https://developer.mozilla.org/en-US/docs/Web/API/Window/pagehide_event)
|
|
- [Google Chrome recommendation](https://developer.chrome.com/docs/web-platform/page-lifecycle-api#the_unload_event)
|
|
## Consequences
|
|
|
|
- Memory leak problem in composer on TMail is resolved.
