About Block Weight Inspector
From the official readme · v0.1.0Description
Block Weight Inspector adds a sidebar panel in the block editor that maps blocks in the current post/page to the CSS and JS assets they register. It estimates local asset sizes, highlights top offenders, and exports a JSON report. It can also generate a suggested conditional-loading snippet to help you dequeue assets when a block is not present.
It also adds a Tools -> Block Weight Inspector screen for auditing existing posts without opening the editor.
Note: The inspector preserves block comment delimiters when analyzing content so parse_blocks() remains accurate after sanitization.
Key features:
- Block -> asset mapping using registered block metadata.
- Estimated size for local assets.
- Top offenders summary and full asset list.
- JSON export for sharing or auditing.
- Suggested conditional-loading rules (review before use).
Installation
- Upload the plugin folder to
/wp-content/plugins/. - Activate the plugin through the Plugins menu in WordPress.
- Open the block editor and use the “Block Weight Inspector” sidebar.
Frequently asked questions
Does this load assets on the front-end?
No. The inspector only runs in the block editor and does not enqueue anything on the front-end.
Why is a size shown as “remote/unknown”?
Only local files are measured by default. You can optionally enable remote size lookup in the inspector panel or Tools page, and the preference is saved per user.
Are the suggested dequeue rules safe?
They are suggestions only. Some plugins enqueue assets for reasons outside of blocks. Always review before using.
