37-44: Hardcoded Ukrainian strings break internationalization.The incomplete quiz message uses hardcoded Ukrainian text instead of translation keys. This means English and Polish users will see Ukrainian text when their quiz times out with partial answers.
Compare with the other branches that correctly use
t('timeUp.title')andt('timeUp.message').🌐 Proposed fix using translation keys
if (isIncomplete && answeredCount > 0) { return { emoji: '⏱️', - title: 'Час вийшов', - message: `Ви відповіли на ${answeredCount} з ${total} питань. Результат не зараховано.`, + title: t('timeUp.title'), + message: t('incompleteMessage', { answered: answeredCount, total }), color: 'text-orange-600 dark:text-orange-400', }; }You'll need to add the
incompleteMessagekey to your translation files (en.json, uk.json, pl.json) with appropriate interpolation.frontend/components/quiz/QuizContainer.tsx (1)
60-77: Wrap switch case declaration in a block to prevent scope leakage.The
answersWithoutThisQuestionconst declaration inside the switch case can be accessed by other cases, which is a common source of bugs. Per static analysis, wrap it in a block.🔧 Suggested fix
case 'ANSWER_SELECTED': + { const answersWithoutThisQuestion = state.answers.filter( a => a.questionId !== action.payload.questionId ); return { ...state, selectedAnswerId: action.payload.answerId, questionStatus: 'revealed', answers: [ ...answersWithoutThisQuestion, { questionId: action.payload.questionId, selectedAnswerId: action.payload.answerId, isCorrect: action.payload.isCorrect, answeredAt: new Date(), }, ], }; + }

In @frontend/db/seed-quiz-angular-advanced.ts:
- Around line 192-194: The usage strings printed for running the script are
incorrect; update the three console.log messages that currently reference
"db/seeds/seed-quiz-angular-advanced.ts" to the actual path
"db/seed-quiz-angular-advanced.ts" (the console.log calls in this file that
print Usage, Example, and Or upload all) so the CLI examples match the file
location.
In @frontend/db/seed-quiz-angular.ts:
- Around line 190-195: Update the usage/help text in the argument-check branch
so the printed path matches the actual file location; replace occurrences of
"db/seeds/seed-quiz-angular.ts" with "frontend/db/seed-quiz-angular.ts" in the
console.log/console.error block (the code that checks partArg in
seed-quiz-angular.ts) so the usage, example and "upload all" messages point to
the correct path.
In @frontend/db/seed-quiz-nodejs.ts:
- Around line 190-195: The usage/help messages printed in the if (!partArg)
branch reference the wrong filename/path; update the three console.log lines
inside that block (the usage & example lines shown in the seed check) to
reference the actual script name frontend/db/seed-quiz-nodejs.ts (e.g., "Usage:
npx tsx frontend/db/seed-quiz-nodejs.ts <part-number>", "Example: npx tsx
frontend/db/seed-quiz-nodejs.ts 1", and the "all" variant), leaving the rest of
the logic (process.exit(1)) unchanged so the message matches the real file and
invocation.
In @json/quizzes/angular/advanced/seed-quiz-angular-advanced.ts:
- Around line 186-191: The usage/help messages printed when partArg is missing
reference the wrong file path; update the console.log strings that currently
show "db/seeds/seed-quiz-angular-advanced.ts" to the actual script path used
here (the current file name used in the code: seed-quiz-angular-advanced.ts
under its package), e.g. change the usage and example lines to reflect
"json/quizzes/angular/advanced/seed-quiz-angular-advanced.ts" (or adjust to a
canonical invocation your project uses), or alternatively move the file to match
the printed path—ensure the console.log messages and example match the real
location so the usage is accurate.
- Around line 1-14: The seed file's imports (db, categories, quizzes,
quizTranslations, quizQuestions, quizQuestionContent, quizAnswers,
quizAnswerTranslations, quizAttempts) are resolving incorrectly because the file
is in json/quizzes/angular/advanced; either move the file into the same
directory as the DB code (so existing imports work) or change the import
statements to import the db instance and schema symbols from the real frontend
DB module locations; update the import sources for "db" and the "./schema/*"
modules to point at the modules that actually export those symbols so the named
imports (db, categories, quizzes, quizTranslations, quizQuestions,
quizQuestionContent, quizAnswers, quizAnswerTranslations, quizAttempts) resolve
correctly.
- Around line 64-68: The loadQuestions function uses the wrong base folder;
update the path creation in loadQuestions to point to the actual JSON location
by joining process.cwd() with 'json', 'quizzes', 'angular', 'advanced' and the
file name `angular-advanced-quiz-part${partNumber}.json` so loadQuestions reads
from the correct JSON files.
In @json/quizzes/angular/beginner_medium/seed-quiz-angular.ts:
- Around line 64-68: The loadQuestions function is using join(process.cwd(),
'data', ...) directly; replace that with the same projectRoot detection pattern
used in other seed scripts: determine projectRoot by checking filesystem
existence with existsSync (imported from 'fs'), set projectRoot to the detected
path, then use join(projectRoot, 'data', `angular-quiz-part${partNumber}.json`)
to build partPath and read the file; update loadQuestions to reference
projectRoot (same variable name and detection logic as in seed-quiz-vue.ts /
seed-quiz-nodejs-advanced.ts) so the data path resolution is consistent.
- Around line 1-14: This duplicate seed file is outdated and will break due to
incorrect relative imports and hardcoded paths; either delete
json/quizzes/angular/beginner_medium/seed-quiz-angular.ts or sync it with
frontend/db/seed-quiz-angular.ts by replacing its imports and path logic: update
the import list to include existsSync from 'fs', change './index' and
'./schema/...' imports to the same module paths used in frontend/db (or use
absolute/projectRoot detection like the working file) and replace
join(process.cwd(), 'data', ...) with the projectRoot detection logic used in
the canonical seed (ensure functions/consts like projectRoot, readFileSync
usage, and the same db/schema references — quizzes, quizTranslations,
quizQuestions, quizQuestionContent, quizAnswers, quizAnswerTranslations,
quizAttempts — match the frontend version).
In @json/quizzes/node/advanced/seed-quiz-nodejs-advanced.ts:
- Around line 186-191: Update the CLI usage strings so they reflect the actual
file location instead of db/seeds/...; replace the three console.log usages in
the block that checks partArg (the lines using 'Usage: npx tsx
db/seeds/seed-quiz-nodejs-advanced.ts <part-number>' and the example and "upload
all" lines) to reference the real path
'json/quizzes/node/advanced/seed-quiz-nodejs-advanced.ts' (or the finalized
location) so the messages shown when partArg is missing are accurate.
- Around line 64-68: The path construction in loadQuestions is wrong: update the
partPath used in loadQuestions to point to the actual JSON directory
(json/quizzes/node/advanced) instead of data; locate the partPath variable in
the loadQuestions function and change the join(...) call so it builds
process.cwd(), 'json', 'quizzes', 'node', 'advanced',
`nodejs-advanced-quiz-part${partNumber}.json` ensuring the filename format
matches nodejs-advanced-quiz-part{n}.json.
- Around line 1-14: The seed script is in the wrong directory and will break its
relative imports; move seed-quiz-nodejs-advanced.ts into the frontend/db/
directory alongside the other seed scripts so its existing relative imports
(import { db } from './index'; import { categories } from './schema/categories';
import { ... } from './schema/quiz';) resolve correctly, or if you must keep the
file in json/quizzes/, update the import paths to point to the actual db module
locations (e.g., adjust './index' and './schema/...' to the correct relative
path into frontend/db/), and re-run the provided verification commands to
confirm all seed scripts live under frontend/db/.
In @json/quizzes/node/beginner_medium/seed-quiz-nodejs-fundamentals.ts:
- Around line 64-68: The loadQuestions function uses process.cwd() and lacks a
file existence check; change it to use the same projectRoot detection pattern as
sibling seed scripts (compute projectRoot, then build the path under
json/quizzes/node/beginner_medium or the canonical directory used by other
scripts) and call existsSync to verify the file exists before readFileSync; if
the file is missing, throw or log a clear error. Update references inside
loadQuestions (function name) and local variables (partPath, partData)
accordingly so the path resolution and existence check match the other seed
scripts.
- Around line 1-14: The imports at the top (db, categories, quizzes,
quizTranslations, quizQuestions, quizQuestionContent, quizAnswers,
quizAnswerTranslations, quizAttempts) are pointing to non-existent relative
paths (e.g., './index' and './schema/categories'); update those import
specifiers to the correct module locations under the actual frontend/db package
(replace './index' and './schema/...' with the appropriate 'frontend/db/...'
module paths used by the project) so symbols like db and categories resolve at
runtime, and change the data file loading (currently using join(process.cwd(),
'data', ...)) to load from the seed file's directory (use the script's directory
as the base, e.g., using __dirname or path.join(dirname,
'nodejs-quiz-part1.json')) so readFileSync reads the local JSON files like
nodejs-quiz-part1.json successfully.
In @json/quizzes/vue/beginner_medium/seed-quiz-vue.ts:
- Around line 186-189: Update the usage/help messages currently printed by the
script (the console.error and console.log calls) to reference the actual path
and invocation for this file (json/quizzes/vue/beginner_medium/seed-quiz-vue.ts)
instead of db/seeds/seed-quiz-vue.ts; locate the console.error('Error: Please
specify which part to upload') and the following console.log(...) lines and
change their strings to show the correct path and examples (e.g., npx tsx
json/quizzes/vue/beginner_medium/seed-quiz-vue.ts <part-number> and
corresponding example for "all").
- Around line 64-68: The loadQuestions function currently builds partPath using
process.cwd() which can point to the wrong working directory; change it to
resolve the JSON files relative to this script by using __dirname (i.e. compute
partPath with path.join(__dirname, `vue-quiz-part${partNumber}.json`) or
join(__dirname, 'json/quizzes/vue/beginner_medium', ... ) depending on where the
files live) so loadQuestions reads the files next to the script; if this repo
uses ES modules, derive __dirname via fileURLToPath(import.meta.url) and dirname
before using it.
🧹 Nitpick comments (8)
json/quizzes/vue/beginner_medium/seed-quiz-vue.ts (1)
211-211: Hardcoded answer count may be misleading.The summary assumes exactly 4 answers per question. Consider calculating the actual total dynamically if answer counts vary.
Suggested fix
Track actual answer count during seeding:
let totalQuestions = 0; + let totalAnswers = 0; for (let i = 1; i <= 4; i++) { const questions = await loadQuestions(i); await seedQuestions(questions, quizId, i); totalQuestions += questions.length; + totalAnswers += questions.reduce((sum, q) => sum + q.answers.length, 0); } console.log('\nAll parts seeded successfully!'); console.log(` - 1 quiz with ${LOCALES.length} translations`); console.log(` - ${totalQuestions} questions total`); - console.log(` - ${totalQuestions * 4} answers with ${LOCALES.length} translations each`); + console.log(` - ${totalAnswers} answers with ${LOCALES.length} translations each`);frontend/db/seed-quiz-angular-advanced.ts (2)
2-2: Minor formatting: Missing space after comma in import.Suggested fix
-import { readFileSync,existsSync } from 'fs'; +import { readFileSync, existsSync } from 'fs';
186-237: Consider wrapping seed operations in a transaction.If the seeding process fails midway (e.g., during
seedQuestions), partial data may remain in the database, leading to an inconsistent state. Wrapping the quiz creation and question seeding in a transaction would ensure atomicity—either all data is committed or none.This is a recommended improvement for robustness, especially when seeding multiple parts with the
allargument.json/quizzes/angular/advanced/seed-quiz-angular-advanced.ts (1)
96-118: Consider wrapping delete/update/insert operations in a transaction.The sequence of deleting questions/translations, updating the quiz, and inserting new translations is not atomic. If the script fails mid-way (e.g., after line 97 but before line 115), data could be left in an inconsistent state.
Suggested approach using db.transaction
if (existing) { - const existingAttempt = await db.query.quizAttempts.findFirst({ - where: eq(quizAttempts.quizId, existing.id), - }); - if (existingAttempt) { - throw new Error(`Quiz ${QUIZ_METADATA.slug} has existing attempts. Aborting to avoid data loss.`); - } - - await db.delete(quizQuestions).where(eq(quizQuestions.quizId, existing.id)); - await db.delete(quizTranslations).where(eq(quizTranslations.quizId, existing.id)); - await db.update(quizzes).set({ - ... - }).where(eq(quizzes.id, existing.id)); - - const quizId = existing.id; - for (const locale of LOCALES) { - await db.insert(quizTranslations).values({ ... }); - } - - return quizId; + return await db.transaction(async (tx) => { + const existingAttempt = await tx.query.quizAttempts.findFirst({ + where: eq(quizAttempts.quizId, existing.id), + }); + if (existingAttempt) { + throw new Error(`Quiz ${QUIZ_METADATA.slug} has existing attempts. Aborting to avoid data loss.`); + } + + await tx.delete(quizQuestions).where(eq(quizQuestions.quizId, existing.id)); + await tx.delete(quizTranslations).where(eq(quizTranslations.quizId, existing.id)); + await tx.update(quizzes).set({ ... }).where(eq(quizzes.id, existing.id)); + + for (const locale of LOCALES) { + await tx.insert(quizTranslations).values({ ... }); + } + + return existing.id; + }); }frontend/db/seed-quiz-nodejs.ts (2)
100-122: Consider transaction wrapping for atomicity.Same as noted for the Angular Advanced seed script: the delete/update/insert sequence for existing quizzes would benefit from transaction wrapping to prevent partial data states on failure.
145-184: Optional: Consider batch inserts for performance.The current implementation makes individual
INSERTcalls for each question, locale content, answer, and answer translation. For 40 questions with 3 locales and ~4 answers each, this results in ~600+ individual DB operations.Drizzle supports batch inserts that could reduce this significantly, though for a one-time seed script the current approach is acceptable.
frontend/db/seed-quiz-angular.ts (2)
100-122: Same transaction wrapping recommendation applies.For consistency with the other seed scripts, consider wrapping the delete/update/insert sequence in a transaction.
16-62: Optional: Extract shared utilities to reduce duplication.The type definitions (
Locale,QuestionData,QuizPartData), helper functions (createExplanation), and core seeding logic (ensureQuizExists,seedQuestions) are nearly identical across all seed scripts (seed-quiz-angular.ts,seed-quiz-nodejs.ts,seed-quiz-angular-advanced.ts, etc.).Consider extracting these into a shared
seed-utils.tsmodule that exports:
- Common types and interfaces
createExplanationhelper- Generic
ensureQuizExists(metadata, categorySlug)function- Generic
seedQuestions(questions, quizId, partNumber)functionEach quiz-specific script would then only define its metadata and file paths.

26-42: LGTM on the interval-based countdown logic.The effect correctly uses
endTimein its dependency array, ensuring the interval recalculates remaining time based on the stable quiz start time. Using a 100ms interval provides smooth UI updates whilequeueMicrotask(onTimeUp)properly defers the callback to avoid state updates during render.
44-57: Good handling of tab visibility changes.The visibility change handler ensures the timer display syncs correctly when users return to the tab, preventing any visual discrepancy between displayed time and actual remaining time.
11-24: Well-implemented fix for the timer restart issue.The introduction of
startedAtprop elegantly solves the language-switch timer restart problem. By computingendTimefrom a stablestartedAttimestamp rather thanDate.now()at mount time, the timer now correctly maintains its remaining time across component remounts.Key improvements:

Either:
- Move this file to

Imports are broken and will fail at runtime. File imports from non-existent relative paths.
The imports reference './index' and './schema/categories' which don't exist in json/quizzes/node/beginner_medium/. These modules are located in frontend/db/, not relative to this seed script's directory. The file cannot execute with these imports.
Additionally, the data loading path at line 65 uses join(process.cwd(), 'data', ...) but the actual quiz data files are in the same directory as the script (nodejs-quiz-part1.json, etc.), making readFileSync fail at runtime.

Inconsistent data path and missing file existence check.
This script uses join(process.cwd(), 'data', ...) while the other seed scripts in this PR (e.g., seed-quiz-nodejs-advanced.ts, seed-quiz-vue.ts) use a projectRoot detection pattern with existsSync. Additionally, the path structure differs—other scripts reference json/quizzes/<category>/... paths.
Consider aligning with the pattern used in sibling scripts for consistency:

the file is missing, throw or log a clear error. Update references inside
loadQuestions (function name) and local variables (partPath, partData)
accordingly so the path resolution and existence check match the other seed
scripts.

Verify import paths resolve correctly from this file location.
This file is located at json/quizzes/vue/beginner_medium/seed-quiz-vue.ts, but the imports reference './index' and './schema/...'. Based on the codebase structure, the db module is at frontend/db/index.ts. These relative paths will not resolve correctly from the current file location.
Suggested fix
Either:
- Move this script to
frontend/db/seeds/directory to match the usage message, or - Update imports to use the correct relative path to
frontend/db/:
-import { db } from './index';
-import { categories } from './schema/categories';
+import { db } from '../../../../frontend/db/index';
+import { categories } from '../../../../frontend/db/schema/categories';
import {
quizzes,
quizTranslations,
quizQuestions,
quizQuestionContent,
quizAnswers,
quizAnswerTranslations,
quizAttempts,
-} from './schema/quiz';
+} from '../../../../frontend/db/schema/quiz';📝 Committable suggestion

Incorrect JSON file path will cause runtime failure.
The path join(process.cwd(), 'data', ...) looks for files in a data/ directory relative to the working directory. According to the PR context, the JSON files (vue-quiz-part1.json through vue-quiz-part4.json) are located in json/quizzes/vue/beginner_medium/ alongside this script.
Suggested fix
async function loadQuestions(partNumber: number): Promise<QuestionData[]> {
- const partPath = join(process.cwd(), 'data', `vue-quiz-part${partNumber}.json`);
+ const partPath = join(__dirname, `vue-quiz-part${partNumber}.json`);
const partData: QuizPartData = JSON.parse(readFileSync(partPath, 'utf-8'));
return partData.questions;
}Note: If using ES modules, you may need to derive __dirname using:
import { fileURLToPath } from 'url';
import { dirname } from 'path';
const __dirname = dirname(fileURLToPath(import.meta.url));🤖 Prompt for AI Agents
In @json/quizzes/vue/beginner_medium/seed-quiz-vue.ts around lines 64 - 68, The
loadQuestions function currently builds partPath using process.cwd() which can
point to the wrong working directory; change it to resolve the JSON files
relative to this script by using __dirname (i.e. compute partPath with
path.join(__dirname, `vue-quiz-part${partNumber}.json`) or join(__dirname,
'json/quizzes/vue/beginner_medium', ... ) depending on where the files live) so
loadQuestions reads the files next to the script; if this repo uses ES modules,
derive __dirname via fileURLToPath(import.meta.url) and dirname before using it.
