From 27d783ea937d937fa0bc93130d2c314ac927cc1f Mon Sep 17 00:00:00 2001 From: sahasraa09 Date: Mon, 6 Jul 2026 22:45:57 +0530 Subject: [PATCH 01/18] Add Digital Learning Companion feature MIME-Version: 1.0 Content-Type: text/plain; charset=UTF-8 Content-Transfer-Encoding: 8bit A persistent animated animal sidekick that grows from real learning progress. Backend - New companion module: controller, service, repository, validators, classes - GET /api/companion/me — current state with live progress - POST /api/companion/me — select or switch animal (panda/fox/penguin/dog/cat) - CompanionService._computeStage returns proper stages 0-5 - CompanionRepository.upsert uses findOneAndUpdate({returnDocument: 'after'}) - SelectAnimalBody class with class-validator decorators - CompanionController uses @JsonController (auto body-parser) + IUser - #companion/*.js import path alias Frontend - CompanionWidget component with always-mounted canvas + overlay picker - companionRenderer.js — faithful prototype-embed port (320x360 canvas, requestAnimationFrame loop preserved) - companionRenderer.d.ts — TS types for renderer - companion-store (Zustand): companion, hasSelected, isLoading, fetchCompanion, selectAnimal - companion.ts types: CompanionAnimal, CompanionMood, ICompanion - StudentDashboard renders Scripts - scripts/switch-test.js — end-to-end switch-animal test - scripts/inspect-body.js — body-parsing debug helper Switch-animal fix - userId stored as IUser object in Mongo: fixed via _userId() helper - Inline TS interface as @Body() doesn't deserialize: fixed via SelectAnimalBody class - @Controller vs @JsonController (body parser): fixed by using @JsonController - Defensive animal whitelist at widget + factory + scene call sites --- backend/package.json | 3 +- .../modules/companion/classes/Companion.ts | 40 + .../modules/companion/classes/interfaces.ts | 50 ++ .../classes/validators/CompanionValidators.ts | 8 + backend/src/modules/companion/container.ts | 19 + .../controllers/CompanionController.ts | 47 ++ backend/src/modules/companion/index.ts | 38 + .../providers/mongodb/CompanionRepository.ts | 97 +++ .../companion/services/CompanionService.ts | 191 +++++ backend/src/modules/companion/types.ts | 6 + frontend/src/app/pages/student/dashboard.tsx | 4 + .../components/Companion/CompanionWidget.tsx | 250 +++++++ .../Companion/companionRenderer.d.ts | 29 + .../components/Companion/companionRenderer.js | 706 ++++++++++++++++++ frontend/src/store/companion-store.ts | 55 ++ frontend/src/types/companion.ts | 10 + scripts/inspect-body.js | 34 + scripts/switch-test.js | 52 ++ 18 files changed, 1638 insertions(+), 1 deletion(-) create mode 100644 backend/src/modules/companion/classes/Companion.ts create mode 100644 backend/src/modules/companion/classes/interfaces.ts create mode 100644 backend/src/modules/companion/classes/validators/CompanionValidators.ts create mode 100644 backend/src/modules/companion/container.ts create mode 100644 backend/src/modules/companion/controllers/CompanionController.ts create mode 100644 backend/src/modules/companion/index.ts create mode 100644 backend/src/modules/companion/repositories/providers/mongodb/CompanionRepository.ts create mode 100644 backend/src/modules/companion/services/CompanionService.ts create mode 100644 backend/src/modules/companion/types.ts create mode 100644 frontend/src/components/Companion/CompanionWidget.tsx create mode 100644 frontend/src/components/Companion/companionRenderer.d.ts create mode 100644 frontend/src/components/Companion/companionRenderer.js create mode 100644 frontend/src/store/companion-store.ts create mode 100644 frontend/src/types/companion.ts create mode 100644 scripts/inspect-body.js create mode 100644 scripts/switch-test.js diff --git a/backend/package.json b/backend/package.json index bfe256567..83796e306 100644 --- a/backend/package.json +++ b/backend/package.json @@ -27,7 +27,8 @@ "#genAI/*.js": "./build/modules/genAI/*.js", "#settings/*.js": "./build/modules/settings/*.js", "#setting/*.js": "./build/modules/setting/*.js", - "#anomalies/*.js": "./build/modules/anomalies/*.js" + "#anomalies/*.js": "./build/modules/anomalies/*.js", + "#companion/*.js": "./build/modules/companion/*.js" }, "type": "module", "keywords": [], diff --git a/backend/src/modules/companion/classes/Companion.ts b/backend/src/modules/companion/classes/Companion.ts new file mode 100644 index 000000000..b9d1a13a7 --- /dev/null +++ b/backend/src/modules/companion/classes/Companion.ts @@ -0,0 +1,40 @@ +import {CompanionAnimal, GrowthStage, CompanionMood, ICompanion} from './interfaces.js';

The fallback still happens silently (the SCENES lookup was always working), so the warnings were pure noise. - widget: catch uncaught errors in selectAnimal click handlers so a failed selection doesn't leave the user stuck on the picker with no feedback. Now closes the picker regardless of outcome; the store records the error and a future inline UI can surface it. - widget: pause the 30s poll while the tab is hidden (Page Visibility API). On tab focus, fire one immediate catch-up fetch so the widget reflects current state without waiting up to 30s. - store: dedupe concurrent fetchCompanion calls via an in-flight promise. React Strict Mode and the new 30s poll could otherwise race two GET /api/companion/me requests and have whichever resolves last clobber the other's state. --- .../components/Companion/CompanionWidget.tsx | 29 ++++++-- .../components/Companion/companionRenderer.js | 3 - frontend/src/store/companion-store.ts | 68 +++++++++++-------- 3 files changed, 64 insertions(+), 36 deletions(-) diff --git a/frontend/src/components/Companion/CompanionWidget.tsx b/frontend/src/components/Companion/CompanionWidget.tsx index 7b8889dfa..1bc981329 100644 --- a/frontend/src/components/Companion/CompanionWidget.tsx +++ b/frontend/src/components/Companion/CompanionWidget.tsx @@ -117,7 +117,6 @@ function CompanionCanvas({ animal === "dog" || animal === "cat" ) ? animal : "panda"; - console.log("[CompanionCanvas] prop change", {animal: safeAnimal, mood, progress, idleDays, quizScore}); r.setAnimal(safeAnimal); r.setMood(toPrototypeMood(mood, progress)); r.setProg(progress); @@ -158,13 +157,28 @@ export function CompanionWidget() { // Fetch on mount, then auto-poll every 30s so mood/progress/idle stay fresh // without a full page reload (matches the polling interval documented in the - // store API contract). + // store API contract).

POST /api/auth/signup returned 500 when the Firebase Auth client SDK had already created the user (which is the normal flow: AuthPage calls createUserWithEmail first, then POSTs to /api/auth/signup). Fix: catch auth/email-already-exists and fetch the existing Firebase user record so we can still create the Mongo user. 2. currentUserChecker leaked Firebase Admin SDK errors as HTTP 500 instead of 401. The shared error handler only maps UnauthorizedError to 401 — anything else falls through to the generic Error → 500 branch. Now we translate auth/* codes to a friendly UnauthorizedError before they bubble. Also tidied authorizationChecker's catch (no more console.log in production paths, type-safe error narrowing). 3. api-client crashed on 204 No Content because response.json() throws on empty bodies. /api/companion/me returns 204 when the user hasn't picked an animal yet — the dashboard now sees the picker instead of a JSON parse error. Also: non-JSON success bodies are surfaced as strings rather than thrown, and 4xx/5xx bodies are parsed first so .message is still useful.
