Part of the follow notification outage fix. Backend: ecency/enotify-py#20. Web: ecency/vision-web#1708.

Problem

enotify emits four follow-family types (follow, unfollow, ignore, blacklist), all sharing ACTIVITY_MAIN_TYPE_FOLLOW. None of them appeared in any of the three client gates, so even with a healthy backend they were dropped:

  • the foreground FCM allowlist, so the unread badge did not bump
  • the websocket allowlist, so no foreground banner and no badge refresh
  • ForegroundNotification's own type union and render gate

The vocabulary bug

Separately, that FCM allowlist held the websocket spellings. enotify speaks two vocabularies for the same events:

Transport Source Delegation Payout
Push (FCM data.type) push/format.py custom_data['type'] delegation payout
Websocket (wsData.type) helper.py str_activity_type() delegations payouts

The list said delegations/payouts, so those two never matched an FCM message at all and the badge went stale for them.

Both lists move to src/constants/notificationTypes.ts, which documents the split and is pinned by a test. This drift is what the bug was made of, so it should fail loudly rather than silently stop matching.

Also fixed

  • ForegroundNotification._onPress sent everything that was not a transfer or delegation to SCREENS.POST with a concatenated permlink. The follow family carries no permlink, so tapping the banner opened nothing. It now routes to the actor's profile. The union and switch also accept singular delegation, since FCM delivers that spelling.
  • notificationContainer routed only follow to the profile, leaving the other three untappable, and disagreeing with the push router in useInitApplication which already handles all three.
  • _enableNotification's no-settings fallback was the literal [1,2,3,4,5,6,13,15,22], omitting 10, 19, 20 and 21. A fresh login therefore got no delegations, payouts, account_update or weekly_earnings pushes until it saved settings once. It now derives from notifyTypesConst so it cannot drift. All 13 values are in enotify's notify_type_list, so device registration still validates.
  • New notification.blacklist string. Needs pushing through Crowdin.

Verification

tsc --noEmit clean, eslint clean, jest 81 suites / 1080 tests pass (was 80 / 1076).

Verified by mutation: putting the plural spellings back into the FCM list fails two of the new cases.

⚠️ Not exercised on a device. The banner, tap routing and badge behaviour are code-verified only, and want a real follow against a test account once #20 is deployed.

…ulary

Backend counterpart: ecency/enotify-py#20.

enotify emits four follow-family types (follow, unfollow, ignore, blacklist),
all sharing ACTIVITY_MAIN_TYPE_FOLLOW. None of them appeared in any of the three
client gates, so even with a healthy backend they were dropped:

- the foreground FCM allowlist, so the unread badge did not bump
- the websocket allowlist, so no foreground banner and no badge refresh
- ForegroundNotification's own type union and render gate

Separately, that FCM allowlist held the WEBSOCKET spellings. enotify speaks two
vocabularies for the same events: push/format.py sets custom_data['type'] to
singular 'delegation' and 'payout', while helper.py str_activity_type() returns
plural 'delegations' and 'payouts'. Those two therefore never matched an FCM
message at all, and the badge went stale for them.

Both lists move to src/constants/notificationTypes.ts, which documents the split
and is pinned by a test. That is the drift this bug was made of, so it should
fail loudly rather than silently stop matching.

Also:
- ForegroundNotification._onPress sent everything that was not a transfer or
  delegation to SCREENS.POST with a concatenated permlink. The follow family
  carries no permlink, so it opened nothing. It now routes to the actor's
  profile. The union and the switch also accept the singular 'delegation' now
  that FCM delivers it.
- notificationContainer routed only 'follow' to the profile, leaving the other
  three untappable and disagreeing with the push router in useInitApplication,
  which already handles all three.
- _enableNotification's no-settings fallback was the literal
  [1,2,3,4,5,6,13,15,22], omitting 10, 19, 20 and 21, so a fresh login got no
  delegations, payouts, account_update or weekly_earnings pushes until it saved
  settings once. It now derives from notifyTypesConst, so it cannot drift.
  All 13 values are in enotify's notify_type_list, so registration still
  validates.
- new notification.blacklist string.

tsc clean. jest 81 suites / 1080 tests pass. Verified by mutation: putting the
plural spellings back into the FCM list fails two of the new cases.

Fix follow-family notifications and transport vocabularies

🐞 Bug fix 🧪 Tests 🕐 20-40 Minutes

Grey Divider

AI Description

• Recognizes all follow-family events across FCM, websocket, banners, and routing.
• Separates transport-specific notification vocabularies to prevent silent allowlist mismatches.
• Derives default push subscriptions from settings mappings and tests vocabulary invariants.

High-Level Assessment

The following are alternative approaches to this PR:

1. Normalize types at transport boundaries
  • ➕ Provides one canonical internal notification vocabulary.
  • ➕ Simplifies downstream type unions, switches, and routing checks.
  • ➕ Allows exhaustive typing over a single notification type enum.
  • ➖ Requires explicit adapters for both FCM and websocket payloads.
  • ➖ Broadens an outage fix into a larger notification pipeline refactor.
  • ➖ Could obscure raw backend values during debugging and rollout.

Recommendation: Keep the PR's explicit transport-specific allowlists for this fix because they document backend contracts and minimize rollout risk. Boundary normalization is a reasonable follow-up if additional consumers emerge, but the focused constants and invariant tests provide the clearest immediate protection against vocabulary drift.

Review Change Stack

📝 Walkthrough

Walkthrough

The change centralizes notification type lists and updates FCM, WebSocket, foreground display, default settings, translation, and navigation handling for delegation and follow-family notifications.

Changes

Notification handling

Layer / File(s) Summary
Centralize notification vocabularies
src/constants/notificationTypes.ts, src/constants/notificationTypes.test.ts, src/screens/application/container/applicationContainer.tsx
Shared FCM, WebSocket, and follow-family type lists replace inline lists. Tests verify transport-specific spellings and membership.
Handle foreground notification display and presses
src/components/foregroundNotification/foregroundNotification.tsx, src/config/locales/en-US.json
Foreground notifications support delegation and follow-family types. Follow-family presses open profiles, delegation uses wallet handling, and blacklist receives an English message.
Handle WebSocket events and notification routes
src/screens/application/container/applicationContainer.tsx, src/screens/notification/container/notificationContainer.tsx
WebSocket follow-family events build notification titles. Default notification settings include all mapped types. Follow-family taps open the follower profile.

Estimated code review effort: 3 (Moderate) | ~20 minutes

Merge Risk: 🟡 Moderate · up to 840ad

The PR fixes follow-family notifications and transport vocabulary drift, but payout notifications accepted by the inbound handlers are still excluded from foreground rendering and wallet navigation. This bounded correctness issue should be fixed or explicitly accepted before merge.

A rabbit checks the types in line
Delegations hop through the sign
Follow bells ring, profiles gleam
WebSocket paths now join the stream
Blacklist words get a title too
And every route knows where to do

Comment thread src/components/foregroundNotification/foregroundNotification.tsx
Picks up the widened follow-family unions published from vision-web#1708:
WsFollowNotification and ApiFollowNotification now include 'blacklist'.

Not strictly required by this PR. _navigateToNotificationRoute takes data as
any, so the blacklist comparison typechecked against 2.3.93 too. Bumping so the
app is not left behind a published type change it is meant to consume, and per
the release order: web plus SDK first, services live, mobile last. All three
hold now, with enotify deployed.

package.json and yarn.lock edited surgically rather than re-resolving the whole
lockfile. Safe here because 2.3.95 has an identical dependencies and
peerDependencies set to 2.3.93, so the recorded deps block stays correct.

Verified: yarn install --frozen-lockfile passes (the CI gate), the installed
dist carries the widened union, tsc clean, jest 81 suites / 1080 tests pass.
payout, payouts, account_update and weekly_earnings were accepted by both
allowlists but missing from ForegroundNotification's type union, visibility
gate, title switch and tap routing. They refreshed the unread badge and then
silently showed nothing. The review flagged payout; the other three were in the
identical state, so all four are fixed rather than the one instance.

Titles prefer the delivered notification.title/body. Both producers already
build correct text for these (enotify push/format.py for FCM, the websocket
bridge in applicationContainer), so rebuilding the interpolated strings here
would only be a second place to get them wrong. scheduled_published already
does this for its body.

Routing: payout/payouts/weekly_earnings join transfer and delegations in going
to the wallet. account_update is informational and deliberately navigates
nowhere, because the app has no destination for it and the post branch would
otherwise open an empty permlink, which is the same bug already fixed for the
follow family in this PR.

The gate now reads FOREGROUND_BANNER_TYPES from constants/notificationTypes.ts,
and a test asserts it covers every type in both allowlists. That is the guard
this class needed: adding a type upstream without a banner now fails a test
instead of waiting for review. Verified by mutation, reverting the banner list
to its pre-fix state fails that case with the 8 missing entries.

tsc clean, eslint clean, jest 81 suites / 1082 tests pass.
