Completes the Bootstrap 4->5 migration now that every jQuery/BS4 widget is React
(navbar, carousel, dropdowns) — plus the feedback toggle here (Feedback.js:
global `$('#feedback-form').toggle()` -> React state).
- Load Bootstrap 5 CSS from the `bootstrap` npm package in client/index.js
(imported first so app + component styles and react-bootstrap override it).
- Remove the `alexwine:bootstrap-4` meteor package (BS4 CSS + jQuery + BS4 JS).
jQuery for jquery-validation still comes from the npm `jquery` dep.
- Utility renames to BS5: ml-auto->ms-auto, float-right->float-end,
btn-block->w-100, data-toggle->data-bs-toggle (FromNow tooltip).
- forms.scss `.form-label` is no longer a shim (BS5 ships it); comment updated.
Full-app build boots clean; server suite 36 passing. Needs a visual staging pass
across all pages (BS4->5 shifts grid gutters/typography); forms should improve
since react-bootstrap v2 already emitted BS5 markup.
React 19 drops defaultProps on function components. Converted the 9 of
ours that used it (App, Navigation, ReSendEmail, Reconnect, OAuthLoginButton,
PageHeader, Page, EditDocument, EditSubscription) to destructured default
params; App defaults userId/emailAddress in its withTracker instead (it
spreads {...props} widely). Class components keep defaultProps (still
supported). The only defaultProps warnings left are from the react-share
npm package (CreatedButton/Icon), not our code. REST smoke byte-identical.
