docs/ANALYTICS.md (2)
21-24: Align environment variable names and examples with the actual configurationDocs use
POSTHOG_KEY/POSTHOG_HOST, while the production environment config expectsNG_APP_POSTHOG_KEY/NG_APP_POSTHOG_HOST, and the dev example forenvironment.tsdoesn’t match the current code. This can easily lead to PostHog not initializing in some environments.Consider:
- Standardizing on a single pair of env var names (e.g.,
NG_APP_POSTHOG_KEY/NG_APP_POSTHOG_HOST) across.env, GitHub Actions, and both environment files.- Updating the code snippets here so they mirror the real
environment.tsandenvironment.prod.ts.Also applies to: 35-41, 45-50
70-74: Update analytics tooling reference to PostHog for consistencyThe “Add Web App Install Analytics” TODO still mentions GTM/Mixpanel, while the stack has standardized on PostHog.
Consider rephrasing to “Track install events via PostHog” (and similar wording) to avoid confusion about which analytics system should be implemented.
ROADMAP_UX.md (1)
57-323: Phase 2 roadmap is very clear; only minor markdownlint nitsThe Phase 2.1–2.6 breakdown (tasks, durations, success criteria) is well structured and makes planning straightforward. Markdown linters may complain about the
*Status: ...*lines being used like headings; if you care about a clean lint pass, consider turning those into proper#### Statusheadings or disabling MD036 for this file.frontend/src/app/app.config.ts (1)
21-21: Avoid double‑providingPosthogService
PosthogServiceis markedprovidedIn: 'root'and is also added explicitly to theprovidersarray here. That duplication isn’t harmful but is unnecessary and can confuse future readers about where the singleton actually comes from.Consider removing it from
providersand relying solely onprovidedIn: 'root'(or, if you prefer explicit app‑level providers, dropprovidedIn: 'root'from the service).Also applies to: 38-38
frontend/src/app/core/services/posthog.service.ts (2)
19-36: Decouple router subscription from PostHog initialization order
initPageTracking()skips registering theNavigationEndsubscription ifisPostHogAvailable()is false at construction time. That couples page-view tracking to the precise init order ofposthog.initvs. service instantiation (and to test setups), even thoughtrackPageView()already has its own availability guard.Consider always subscribing to router events and keeping the guard only inside
trackPageView():- private initPageTracking(): void { - if (!this.isPostHogAvailable()) { - return; - } - this.routerSub = this.router.events + private initPageTracking(): void { + this.routerSub = this.router.events .pipe(filter((event) => event instanceof NavigationEnd)) .subscribe((event: NavigationEnd) => { // Track page view with route name this.trackPageView(event.urlAfterRedirects); }); }This makes page tracking robust even if PostHog is initialized later or is disabled in certain test environments.
1-5: Confirmposthog-jsbehavior in SSR and non‑browser contextsThe service imports
posthog-jsdirectly and usesdocument.titleinsidetrackPageView(). In an SSR or non‑browser build, this can be problematic ifposthog-jsordocumentisn’t safely shimmed.If you render on the server, consider:
- Guarding analytics behind a browser check (e.g.,
isPlatformBrowser) before calling anyposthogAPIs or touchingdocument.- Verifying that
posthog-js@1.293.0is SSR‑safe (does not referencewindow/documentat module load). If it isn’t, move the import behind a browser guard or usewindow.posthoginjected inmain.tsinstead.Also applies to: 42-54, 204-210
frontend/src/app/core/services/auth.service.ts (1)
164-169: Make PostHog reset robust to async implementationsRight now
resetUser()is wrapped in atry/catch, which only guards against synchronous exceptions. IfresetUser()ever returns a Promise and rejects, that rejection won’t be caught here.Consider making
resetUser()a purely sync fire‑and‑forget wrapper, or explicitly handling potential Promise rejections, e.g.:- try { - this.posthogService.resetUser(); - } catch (error) { - console.warn('Failed to reset PostHog user:', error); - } + try { + const result = this.posthogService.resetUser(); + if (result instanceof Promise) { + void result.catch((error) => + console.warn('Failed to reset PostHog user:', error) + ); + } + } catch (error) { + console.warn('Failed to reset PostHog user:', error); + }

37-44: Dependency additions look consistent with the stackAdding
echartsandposthog-jsat these versions aligns with existing Angular 18 +ngx-echartsusage and the new analytics integration.frontend/src/main.ts (1)
4-28: PostHog initialization is well‑guarded; consider omitting key from logsThe conditional init with try/catch and a global
window.posthogis clean and won’t break bootstrap if analytics fails. You may want to drop the (even truncated) key from the log payload to avoid leaking any part of credentials into shared logs; logging the host and a simple “enabled/disabled” flag is usually enough.frontend/src/environments/environment.prod.ts (1)
8-13: Production PostHog configuration pattern looks safeUsing
NG_APP_POSTHOG_KEY/NG_APP_POSTHOG_HOSTwith an empty‑string fallback avoids committing secrets while keeping analytics enabled when properly configured in the environment.frontend/src/app/core/services/auth.service.ts (1)
13-13: PosthogService DI usage looks goodUsing
inject(PosthogService)alongside other services is consistent and keeps the service tree-shakable. No issues from the DI pattern itself.Also applies to: 54-55
