Developer Notes

Use these notes when reviewing, extending, or maintaining the plugin source.

These notes are for maintainers and contributors.

Source conventions

  • Keep runtime code under the VacuumImageOptimizer namespace.
  • Keep public identifiers prefixed with VACIMG_ or vacimg_.
  • Do not add external image optimization APIs without explicit product direction.
  • Keep changes compatible with WordPress.org review expectations.
  • Preserve backup-first behavior for source-changing operations.

Testing focus

Before release, test activation, wizard completion and skip, settings save, dashboard loading, compression settings, system status, Media Library actions, JPG/PNG/WebP optimization, SVG/GIF skipping, backup creation, restore, bulk queue batches, and debug logs.

Packaging

The WordPress.org ZIP should include only runtime files: main plugin file, readme, uninstall, src, assets, and languages.
