| # TODO: Fix Turbo Warning in Future PR | ||
|
|
||
| ## Issue | ||
| There's a console warning about Turbo being loaded from within the `<body>` element instead of the `<head>`. | ||
|
|
||
| ## Root Cause | ||
| Conflicting requirements between three systems: | ||
| 1. **Turbo** - Wants to be loaded in `<head>` to avoid re-evaluation on page changes | ||
| 2. **Shakapacker** - Requires all `append_javascript_pack_tag` calls to happen before the final `javascript_pack_tag` | ||
| 3. **React on Rails** - The `react_component` helper internally calls `append_javascript_pack_tag` when rendering components in the body | ||
|
|
||
| ## Attempted Solutions That Failed | ||
| 1. Moving `javascript_pack_tag` to head - Breaks because `react_component` calls come after it | ||
| 2. Using `data-turbo-suppress-warning` - Doesn't properly suppress the warning | ||
|
|
||
| ## Potential Future Solutions | ||
| 1. Extract Turbo into a separate pack from stimulus-bundle and load it in the head | ||
| 2. Use `prepend_javascript_pack_tag` instead of `append` for component registration | ||
| 3. Configure React on Rails v16 to use a different component loading strategy | ||
| 4. Investigate if the auto-registration feature has a different recommended pack loading pattern | ||
|
|
||
| ## Current State | ||
| The application works correctly with the pack tags at the end of the body. The Turbo warning is cosmetic and doesn't affect functionality. | ||
|

Prevent startup race: generate packs before webpack processes start
With v16 auto-registration, webpack can error if wp-client/wp-server start before packs exist. Prepend generate_packs to both webpack commands (and optionally Rails) and set HOST/PORT defaults for container/devbox access.
Based on learnings.
