Every subscription add/change/remove recomputed the full geo union
over all 7k+ subscriptions with a synchronous turf.union chain,
freezing the single Node event loop (and thus DDP/HTTP) for minutes.
The same recompute also runs at startup ("Subs union outdated"),
so every restart froze the site too.
calcUnionAsync yields to the event loop periodically during the
union chain, and subsUnion.js now fires recomputes without blocking
Meteor.startup or the observer callbacks, serializing overlapping
triggers instead of stacking them.
Post-swap hardening after a full BS4-removed-class sweep of the codebase:
- LocationAutocomplete passed `root: 'form-group'` to react-places-autocomplete;
BS5 removed `.form-group` (it gave the bottom margin) -> use `mb-3`.
- Drop the unused `popper.js@1` dependency (react-bootstrap bundles
@popperjs/core@2). No source imports it.
Sweep otherwise clean: no other BS4-only utility/component classes remain in JSX
or SCSS. Full-app build boots clean.
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-progress-bar.js (unmaintained wrapper) rendered the progress line
through findDOMNode. Reimplemented LoadingBar with progressbar.js directly
(the wrapper's own underlying dep) via a ref + useEffect — same thin line
(strokeWidth 2, #5A7636), no findDOMNode. Promoted progressbar.js to a
direct dependency and removed react-progress-bar.js. Verified progressbar.js
draws its SVG in-browser; findDOMNode gone from /fires and home; REST smoke
byte-identical.
react-share 2.0 shipped function components with defaultProps (CreatedButton,
Icon) -> React-19-blocking warnings on fire-detail pages. v5 is React-18-safe
and drops them. Removed the GooglePlusShareButton/Icon (Google+ is dead;
removed from react-share in v4+); the other 6 buttons (Facebook, Twitter,
Telegram, WhatsApp, Reddit, Email) are API-compatible. Browser-verified 6
buttons render, no defaultProps warnings. REST smoke byte-identical.
Removes the Router/Switch/Route/Link/LinkContainer legacy-context
warnings. Keeps the shared history singleton (used outside React by
NotificationsObserver + Utils/location) via unstable_HistoryRouter, and
bridges v6 hooks back to v4-shaped history/match/location props with a
new withRouterCompat HOC so the ~20 class pages stay untouched.
- <Switch> -> <Routes>, component= -> element=
- Authenticated/Public -> guard components (children or <Navigate replace>)
- LocationListener -> useLocation + useEffect function
- regex route /fire/:type(active|archive|alert)/:id -> /fire/:type/:id
- history.listen callback is ({ location }) in history v5
Browser-verified: SPA nav, /subscriptions->/login auth redirect,
deep-link /fire/archive/:id (params), browser back/forward. REST smoke
byte-identical.
Removes the largest batch of React-19-blocking warnings: the 0.31
components (Grid, FormGroup, ControlLabel, Navbar.Header/Brand, Checkbox,
SafeAnchor) all leaned on legacy context / defaultProps.
29 files converted: Grid->Container, FormGroup/ControlLabel/FormControl/
HelpBlock -> Form.Group/Label/Control/Text, Checkbox -> Form.Check (label
as prop), bsStyle->variant (default->secondary), bsSize->size,
pull-right->float-end. Custom Col.js now re-exports v2's Col; custom
NavItem.js rewritten self-contained (no SafeAnchor/createChainedFunction);
Navigation.js drops react-bootstrap Navbar (raw markup anyway).
CSS stays on Bootstrap 4 (alexwine:bootstrap-4) for now: the BS4->5 jump
is entangled with the jQuery carousel/swipe + navbar-collapse and is
tracked as separate debt in UPGRADE.md. Only .form-label needed a shim
(forms.scss). Browser-verified home carousel+navbar, signup form + terms
checkbox, login form; REST smoke byte-identical.
react-helmet 5 is unmaintained and breaks under React 18 StrictMode.
Same <Helmet> API in the 15 pages; HelmetProvider wraps <App/> in the
client entry. Browser-verified: per-page titles, meta description and
hreflang alternates all inject. REST smoke byte-identical.
None of them is imported anywhere: reactstrap 5.0.0-alpha.3 was never
adopted (react-bootstrap covers the UI), react-leaflet-sidebarv2 and
react-addons-pure-render-mixin were never used, and react-router-hash-link
only survived as a commented-out import in Index.js.
Drop-in for our usage: email.js only does createTransport(MAIL_URL) and reads
transport.options.auth.user (production-only from() branch) — both verified
identical in v6 (createTransport from a URL still populates options.auth.user).
Actual sending goes through ostrio:mailer (MailTime 2.5), v6-compatible. Mail
server inits clean ('I'm the mail server'); REST smoke byte-identical (12/12).
flowkey:raven (Sentry legacy SDK) is dead on Meteor 3 and, with the old
sentry.comunes.org DSN unreachable, spammed the boot log with 502s on every
exception. Replaced by the modern SDKs (8.x) behind the same ravenLogger.log()
facade so the 6 call sites are unchanged. Empty DSN -> plain console logger
(same behavior as before).
End-to-end verified against a real backend: GlitchTip deployed on aaron
(Sentry-compatible, fits in ~1.5GB vs Sentry's 16GB), fronted at
sentry.comunes.org. A test exception sent from the dev server appeared in
GlitchTip within seconds. REST smoke byte-identical (12/12).
chimp 0.51.1 (Selenium 2 / cucumber e2e runner) was the last dependency
pulling native fibers@1.x, which cannot compile on Node 22 and failed the
clean Docker image build (node-gyp: no prebuilt, no python). Not imported
anywhere. Also add python-is-python3 to the builder stage so node-gyp can
find python for any other native dep. Boot + REST smoke green.
The 1.x native binding was built for another Node ABI and failed to load
(accounts-password silently used the pure-JS fallback) and 1.x does not
compile on Node 22, which would break the Docker image build. 5.1.1 ships
prebuilt Node-22 binaries and loads natively. Boot + REST smoke green.
react/react-dom ^18.3.1 (--legacy-peer-deps for the pinned ancient react-*
libs, which still work on 18 via legacy context but gate React 19). Client
entry uses createRoot. Browser-verified on / and /fires; REST smoke
byte-identical (12/12).
fixtures: drop @cleverbeagle/seeder (sync Mongo, unmaintained) for a small
idempotent async seeder (same dev accounts). sitemaps: drop dead
gadicohen:sitemaps for a WebApp.connectHandlers /sitemap.xml with the same
static page list (the per-fire section was already disabled). Verified on
dev boot: 6 users ensured, sitemap serving; REST smoke byte-identical.
