Lazy Load for Comments

Changelog ​

Full release history for Lazy Load for Comments. The plugin's bundled readme.txt keeps only the latest few releases; the complete history lives here.

2.1.0 ​

Changed ​

  • The plugin moved to the Foxe Labs brand. Nothing about how it works has changed.
  • The PHP namespace is now FoxeLabs\LazyComments\ (was DuckDev\LazyComments\), and the Composer package is foxelabs/lazy-load-for-comments (was duckdev/lazy-load-for-comments).
  • Every link in the plugin now points at the foxelabs.com product page and this documentation site.

Extending the plugin

The old DuckDev\LazyComments\* class names still resolve, so add-ons and custom templates keep working. They are deprecated and raise a _doing_it_wrong() notice — see the architecture overview. Hooks, filters, option keys and setting names are unchanged.

2.0.2 ​

Fixed ​

  • Comments intermittently failed to load on sites behind a full-page cache such as Cloudflare or a host-level page cache. A REST nonce was embedded in the page HTML for logged-out visitors, and a logged-out nonce is only valid for 12–24 hours — well short of how long a cached page keeps being served. Once it expired, WordPress rejected the request with a 403 in rest_cookie_check_errors(), before the plugin's public endpoint was ever reached. Clearing the cache regenerated the nonce and hid the problem until the page aged out again. Logged-out visitors are no longer sent a nonce at all, and a request rejected over a stale one is retried once without it, so pages already sitting in a cache recover on their own. See Full-page caches and CDNs.

This was a regression: 1.0.4 had removed the front-end nonce for the same reason back in 2018, and the 2.0 rewrite reintroduced it.

2.0.1 ​

Fixed ​

  • Comments did not render on Genesis and other classic themes that rely on comments_template() populating comments_by_type.

2.0.0 ​

A complete rewrite.

Added ​

  • Support for block themes, via the core Comments block.
  • A new React settings page under Comments → Lazy Load.
  • Settings for load method, minimum comment count, button text, button style and loader visibility.
  • A per-post cache of the rendered comments block, with a Clear comments cache action in the settings.

Changed ​

  • The comments markup is now fetched through the WordPress REST API instead of admin-ajax.php.
  • Crawlers receive the inline comments by default, so SEO is preserved.
  • The existing 1.x load-method setting is migrated automatically on upgrade.

Removed ​

  • The dependency on jQuery.
