* feat: app user feedback system
Add puter.ui.showFeedbackDialog(), letting users send feedback to an
app's developer. In the app environment the Puter desktop renders the
dialog; on a third-party website a puter.com popup hosts it. The message
is stored in a new app_feedback table and emailed to the app owner's
confirmed email — it never passes through the app's own code.
Feedback is strictly opt-in per app via a new apps.feedback_enabled
column (a real column, not an app-metadata key, so Dev Center's
whole-blob metadata saves can't silently erase it), settable through the
existing puter.apps.update path (feedbackEnabled).
Backend follows the layered stack: AppFeedbackStore (durable count
queries) -> AppFeedbackService (opt-in check, message normalization,
abuse caps, best-effort owner email) -> AppFeedbackController
(POST /app-feedback, GET /app-feedback/target). New app-user-feedback
email template uses the escaping-safe nl2br triple-stash.
Defensive by design:
- requireUserActor blocks app tokens, so feedback can't be submitted
programmatically; guiOriginOnly keeps cross-origin pages out.
- App identity comes only from the validated IPC sender (desktop) or the
browser-attested opener origin (popup), never from message contents.
- The send-feedback popup action is in NON_AUTH_POPUP_ACTIONS, so it
never delivers a token to the opener.
- Layered limits: route rate limits, plus DB-count caps that fail closed
when the limiter backend is down, plus a per-app daily owner-email cap.
- Owner email is fully best-effort: an unconfigured transport,
unconfirmed/unsubscribed/suspended owner, or send failure never fails
the request or blocks storage.
- The dialog and SDK method are resolve-only and always settle, so a
caller is never left hanging.
Migrations for sqlite/mysql/postgres, puter.js types, docs, backend
tests (sqlite + postgres), and a Playwright e2e spec are included.
* feat: add feedback control to the dashboard app-drawer
Surface the feedback dialog directly from the app window's chrome in
dashboard mode: apps that opt in (apps.feedbackEnabled) get a "Send
Feedback" button in the dashboard app-drawer, next to minimize/close.
It opens the same UIWindowAppFeedback dialog, targeting this app by uid.
The control is only rendered when the app opted in — feedback_enabled is
threaded from the launched app's metadata into the window options — and
the dialog still re-checks opt-in server-side, so a stale flag can't send
anywhere. Reuses the existing .dashboard-app-drawer-btn styling and the
app_feedback_title i18n string, so no new CSS or strings.
Adds e2e coverage: the control appears and opens the dialog for an
opted-in app, and is absent for an app that hasn't opted in.
* feat: enable app feedback by default in Dev Center
New apps created in Dev Center now have feedbackEnabled set on creation,
so users can send the developer feedback without any extra setup. A "User
Feedback" toggle in the app's settings lets developers turn it off (and
back on); it's wired into the save payload, the dirty-state tracking, and
the reset-to-original path like the neighboring toggles.
The Save update omits feedbackEnabled unless the toggle is present, and
the backend leaves an omitted field untouched, so the default survives
the create-then-save flow Dev Center runs. Add an SDK apps-suite guard
covering that round-trip (create-on -> unrelated update keeps it -> can
be turned off).
* fix: feedback modal polish + share sender email
Address four issues with the app feedback UI:
- Dashboard app-drawer: the extra "feedback" control pushed the close
button past the drawer's derived width and clipped it. A `has-feedback`
modifier widens the surface by one button + gap so all three controls
fit. The control's glyph is now a message bubble with text lines, which
reads more clearly at 14px than the previous bare speech bubble.
- The feedback dialog is no longer a UIWindow. It's a from-scratch
overlay modal in the spirit of the dashboard modals (uninstall,
add-app): a fixed scrim + centered card with self-contained,
theme-aware color tokens (light default + dark override), a bottom-sheet
layout on narrow screens, backdrop/Escape close, and an entrance
transition. This renders consistently across the three contexts it's
opened from (desktop app-IPC, dashboard drawer, standalone popup), so
the callers no longer pass UIWindow-specific window_options.
- Feedback now shares the sender's email (not just their username) with
the developer so they can respond: the owner email sets Reply-To to the
sender and shows the address in the body — but only when the sender's
email is verified (an unverified address could be anyone's, so it's
never used as a reply target). EmailClient.send gains an optional
replyTo. The dialog note now says the email will be shared.
Tests: e2e updated for the new modal (7 pass); backend feedback suite
covers the verified/unverified sender-email split (sqlite + postgres);
EmailClient + GUI unit suites pass; type-check clean.
* fix: resolve 'app-'-prefixed app names in feedback target lookup
APP_NAME_REGEX allows names beginning with "app-" (e.g. the seeded
app-center), but resolveTargetApp's startsWith('app-') heuristic sent
those to a uid-only lookup with no name fallback, so feedback for such
apps 403'd even when enabled. Use AppStore.resolveApp (uid, then name)
like the rest of the codebase.
* fix: make feedback daily caps fail closed under concurrent submissions
The per-user and per-user-per-app caps were check-then-insert and the
per-app email cap was count-then-send, so parallel requests (or multiple
nodes, or the route limiter failing open) could all read a stale
under-cap count and push past every limit — the exact scenario the
DB-backed caps exist to stop.
Now the user caps recount after the insert (own row included) and roll
the row back with 429 if a burst breached them, and the email cap claims
its slot (email_sent=1) before sending, recounts, and releases the slot
if over cap or if the send fails.
* docs: disclose the Dev Center's feedback-on-by-default in SDK docs/types
The Dev Center deliberately creates apps with feedbackEnabled (see
32c950de5), but the SDK docs, apps.d.ts, and AppFeedbackService's class
doc all described feedback as strictly opt-in / default-false with no
qualification — so a Dev Center developer reading them would wrongly
conclude feedback is off for their app. State the Dev Center behavior
alongside the API default, and correct the update-path docs: an omitted
feedbackEnabled leaves the current value unchanged rather than
defaulting to false.
* fix: don't mint a user-app token as a side effect of the feedback popup
Every embedded_in_popup boot ran the user-app token exchange, and the
exchange is a write: /auth/get-user-app-token bootstraps an app row for
the opener origin, grants flag:app-is-authenticated (what makes the
site count as connected to the account), and creates its AppData dir.
So merely opening — or immediately cancelling — a send-feedback popup
recorded a user<->site relationship the read-only feedback flow never
needs: the server resolves the feedback target from the attested origin
without any of it.
Gate the exchange behind runsUserAppTokenExchange(action) in all three
popup paths that mint (main postAuthActions exchange, temp-user signup
success, manual signup fallback). request-permission keeps the exchange
since grants are written against the app row it bootstraps.
* fix: refuse feedback when the deployment cannot deliver it
With no email transport configured (the common self-hosted default),
submissions were stored in app_feedback — a table with no read path
beyond the abuse-cap COUNTs — the owner email was silently skipped, and
the sender was still shown 'Feedback sent. Thank you!'. The developer
never learns the feedback exists while the user believes it was
delivered.
Gate acceptsFeedback on clients.email.isConfigured so the pre-flight
reports enabled:false (the dialog shows its 'not accepting feedback'
pane) and submit returns 403 instead of swallowing messages. Owner-level
store-without-email cases (unconfirmed owner email, per-app email cap
overflow) keep their existing deliberate semantics.
* fix: settle showFeedbackDialog instead of hanging on older host GUIs
In the app environment showFeedbackDialog awaited an IPC reply with no
capability check. A host GUI that predates this feature (self-hosted
Puter running the live js.puter.com SDK) has no handler for the message
and never replies, so the promise documented as 'never rejects' also
never resolved.
The GUI now advertises the IPC dialogs it can answer via a
puter.gui_features param on the app iframe URL, and the SDK resolves
false when 'feedback-dialog' isn't listed. A reply timeout could not
substitute: legitimate replies only arrive when the user closes the
dialog, so any timeout would false-negative while the user is typing.
Older SDKs ignore the extra param.
* fix: guard app-triggered feedback dialog against desktop-lockout loops
The showFeedbackDialog IPC handler had no re-entry or abuse guard, and
the dialog it opens is a full-viewport overlay above the taskbar and
every window — so 'while (true) await puter.ui.showFeedbackDialog()'
kept the desktop permanently covered (for signed-out users, the same
loop spams the full-page signup window instead). Every dismissal just
settled the promise and let the app immediately reopen it.
Allow one dialog at a time, and back off reopens per app after each
dismissal that sent nothing: 10s, then 60s, then blocked until page
reload. A successful send resets the backoff, and user-initiated paths
(dashboard drawer) are unaffected since they don't go through IPC.
* fix: carry feedback_enabled in suggested/recommended app summaries
launch_app uses options.app_obj verbatim when provided, and the
suggested-apps launch paths (open_item.js, UIWindowSearch.js,
UIDesktop.js) pass summaries from toAppSummary — which omitted
feedback_enabled. So an opted-in editor launched by opening a .txt file
showed no Send Feedback control in the dashboard drawer, while the same
app launched from the Apps tab (full puter.apps.get object) did.
* fix: gate feedback dialog Cancel/X on an in-flight submit
Escape and backdrop clicks were already ignored while the POST was
pending, but the X, Close, and Cancel buttons weren't — clicking one
mid-send settled the promise false and tore down the overlay while the
submission still landed server-side: the developer got the email, the
app was told sent=false, and a user who resubmitted 'the failed one'
sent a duplicate and burned a daily-cap slot.
Apply the same !sending gate to the buttons and disable them visually
while the send is in flight.
* fix: reject feedback origins longer than the source_origin column
readTargetParam accepted values up to 3000 chars but the raw origin is
stored verbatim into source_origin VARCHAR(2048) (MySQL/Postgres), so a
2049-3000 char origin passed every validation and then blew up the
INSERT with an HTTP 500 on Postgres/strict MySQL — or was silently
truncated on non-strict MySQL, corrupting the abuse-forensics value the
column exists for. Cap the param at the column size.
* fix: make the feedback dialog's privacy note match what is shared
The note unconditionally said 'Your email address will be shared with
the developer so they can respond', but AppFeedbackService shares the
username always and the email only when it exists and is verified — an
unverified or temp-user sender was promised a reply path that never
materializes, and nobody was told about the username.
Show 'username and email' when the signed-in user's email is verified,
and 'username' otherwise.
* fix: stop HTML-escaping email subject lines
Subjects were compiled with default Handlebars escaping, so the
app-user-feedback subject rendered a title like "Bob's App & Games" as
"Bob's App & Games" — literal entities in the recipient's mail
client. Subjects are plain-text headers, not HTML; compile them with
noEscape. Header safety is unaffected: the transport encodes newlines
and free-form values collapse whitespace upstream.
* docs: state exactly what showFeedbackDialog shares with the developer
The doc claimed the dialog 'tells the user their username will be
shared', while the dialog's note talked only about the email address and
the implementation shares the username always plus the email (as
Reply-To) only when verified. Describe the actual disclosure: username
always, email when verified.
* docs: document the COOP false-resolve limitation of showFeedbackDialog
Under COOP the popup's opener link is severed, so the SDK deliberately
resolves false while the popup stays open and the user can still submit
(a feedback submission has no server read-back the way a permission
grant does). The documented contract ('resolves to true if the user
submitted feedback') was silently wrong on cross-origin-isolated pages —
state the limitation in the doc and the SDK jsdoc: false means 'not
confirmed', not 'not sent'.
* feat: point the feedback email footer at the Dev Center
The footer told developers to turn feedback off via a puter.apps.update
one-liner, but the toggle lives in the Dev Center app settings — and
Dev Center is where apps get feedback enabled by default in the first
place. Reword it to 'manage it in the Dev Center' with a link built
from config.origin (like app_link) so it holds on self-hosted
deployments.
* test: cover the feedback service and store layers directly
The service owns every feedback business rule — target resolution,
eligibility, message normalization, the durable caps, and the owner-email
preconditions — but was only reachable through the controller's tests. Give
it and the store their own suites so a regression names the layer it broke.
Service coverage adds the branches the route tests could not reach: a
blocked origin resolving to null rather than surfacing a 403, owners who are
suspended or unsubscribed, length measured after normalization, the 24h cap
window boundary, subject-header injection via the app title, and the email
links being rooted at config.origin.
The two describes already labelled `AppFeedbackService ...` move out of the
controller test, which keeps only the caller-facing promise that a failed
send still returns success.
* refactor: prep the feedback cap error once instead of via a factory
Both throw sites are in one call and only one can ever run, so a plain
const reads the same and drops a function that existed only to defer a
constructor.
* Require verified users for app feedback API
Add `requireVerified: true` to both app feedback routes (`GET /target` and `POST /`) in `AppFeedbackController`. This tightens access control so only verified user accounts can fetch feedback targets or submit app feedback.
* Apps: normalize filetype associations to bare lowercase extensions
Suggested-apps lookups match app_filetype_association rows against the
bare lowercase extension ('docx'), but writes stored whatever the
developer typed. Rows like '.docx' never matched, so those apps
silently dropped out of Open With suggestions.
AppStore now canonicalizes on write (trim, lowercase, strip leading
dots, dedupe, drop empties) and tolerates the dotted legacy form on
read: getAppsByFiletype normalizes the requested extension, matches
both 'docx' and '.docx', and dedupes apps associated under both forms.
Cache invalidation keys are normalized the same way. Existing dotted
rows work without a data migration.
* Update apps tests for extension canonicalization
Adjust apps API tests to match current normalization behavior for `filetypeAssociations`: extension values are stored as lowercase bare extensions (e.g. `.txt` -> `txt`), while MIME types remain unchanged. Added inline comments in both test suites to document this expected remap.
* test: tests for puter.js
* fix: ship lockfile for coverage devDeps; tolerate missing base coverage
npm ci failed on CI because package.json gained the babel/istanbul
devDependencies without the matching package-lock.json update. Also make
the coverage workflow's base leg best-effort so a base ref that predates
the coverage script reports without the comparison column instead of
failing the run.
