How does Liferay handle versioning for front-end assets?

Liferay handles versioning for front-end assets primarily through cache-busting techniques and metadata. This approach ensures that users always receive the most up-to-date version of an asset when it is updated. Cache-busting involves appending a unique identifier, such as a version number or content hash, to the URL of an asset. This prevents the browser from serving a cached version and forces it to fetch the latest version. Additionally, Liferay uses metadata to manage and track different versions of an asset, which aids in identifying the latest version available for use.

This method effectively addresses issues related to browser caching, ensuring that new changes are reflected as soon as they are deployed, ultimately enhancing the user experience without requiring complex manual processes or external tools. Other options like incremental backups or manual version control systems do not align with Liferay's streamlined asset management approach for immediate retrieval and efficient updating of frontend resources.
