Complete basic setup configuration #2
Conversation
- Create directory structure (components, problems, locales, utils) - Add ESLint configuration with flat config format (ESLint 9) - Add Prettier configuration - Add TypeScript type definitions for problems and issues - Add i18n utilities for Japanese and English - Add utility functions (formatTime, generateId, clamp) - Configure linting and formatting npm scripts - Verify build and typecheck pass successfully All dev/prod builds are working correctly.
WalkthroughThis pull request introduces linting and formatting tooling (ESLint and Prettier configurations), i18n support with English and Japanese locale files, problem domain types and utility functions for the Bug Sniper application, and systematically normalizes string quote styles from double to single quotes across the codebase.

app/utils/index.ts (3)
10-14: Consider adding input validation for edge cases.The function works correctly for positive integer values, but could be more robust by handling edge cases like negative values and fractional seconds.
Apply this diff to add input validation:
export function formatTime(seconds: number): string { + const validSeconds = Math.max(0, Math.floor(seconds)); - const mins = Math.floor(seconds / 60); - const secs = seconds % 60; + const mins = Math.floor(validSeconds / 60); + const secs = validSeconds % 60; return `${mins.toString().padStart(2, '0')}:${secs.toString().padStart(2, '0')}`; }
20-22: Consider using crypto.randomUUID() for guaranteed uniqueness.While the current implementation is suitable for a game application, using
crypto.randomUUID()would provide better uniqueness guarantees and is supported in modern environments.Apply this diff if stronger uniqueness is needed:
export function generateId(): string { - return `${Date.now()}-${Math.random().toString(36).substring(2, 9)}`; + return crypto.randomUUID(); }
31-33: Consider adding validation for min/max relationship.The function logic is correct, but could benefit from validating that
min <= maxand handling edge cases like NaN values.Apply this diff to add input validation:
export function clamp(value: number, min: number, max: number): number { + if (Number.isNaN(value) || Number.isNaN(min) || Number.isNaN(max)) { + throw new Error('clamp: arguments must be valid numbers'); + } + if (min > max) { + throw new Error('clamp: min must be less than or equal to max'); + } return Math.min(Math.max(value, min), max); }

react-router.config.ts (1)
1-1: LGTM! Formatting consistency applied.The quote style change aligns with the new Prettier configuration introduced in this PR.
.prettierignore (1)
1-8: LGTM! Appropriate ignore patterns configured.The exclusions cover all standard build artifacts, dependencies, and generated files that should not be formatted.
app/locales/en.json (1)
1-18: LGTM! Well-structured locale file.The translation keys are logically organized with clear prefixes, making them easy to maintain and use throughout the application.
tsconfig.json (1)
3-3: LGTM! Formatting consistency applied.Array formatting changes align with the project-wide Prettier configuration without affecting TypeScript behavior.
Also applies to: 10-10
.prettierrc.json (1)
1-10: LGTM! Solid Prettier configuration.The settings strike a good balance between code readability and modern JavaScript best practices. The configuration explains the quote style and formatting changes applied throughout this PR.
.vscode/settings.json (1)
2-4: LGTM! Formatting consistency applied.The indentation change aligns with the Prettier configuration (useTabs: false, tabWidth: 2).
app/entry.server.tsx (1)
1-4: LGTM! Formatting consistency applied.The quote style changes align with the new Prettier configuration without affecting the server-side rendering logic.
Also applies to: 14-14, 38-38
vite.config.ts (1)
1-5: LGTM! Formatting consistency applied.The quote style changes align with the new Prettier configuration without affecting the Vite build setup.
Also applies to: 9-9
app/app.css (1)
1-1: LGTM! The Tailwind v4 syntax is correct.The
@import 'tailwindcss' source('.')syntax is the new Tailwind v4 format for content detection. The Biome parse error is a false positive—Biome's parser doesn't yet recognize this Tailwind v4-specific directive. This syntax is documented and correct.workers/app.ts (1)
1-13: LGTM!The quote normalization is consistent with the project-wide formatting updates.
app/locales/ja.json (1)
1-18: LGTM!The Japanese translations are well-structured with clear key naming conventions. The coverage includes all essential UI elements for the Bug Sniper game.
eslint.config.js (1)
1-77: LGTM! Well-configured ESLint setup.The flat config format is correct for ESLint 9, and the configuration demonstrates good practices:
- Comprehensive globals for the Cloudflare Workers + React environment
- Sensible rule customizations (
react/react-in-jsx-scope: offfor React 19,prop-types: offfor TypeScript)- Proper unused variable handling with
_prefix pattern- Appropriate ignores for build artifacts
app/locales/index.ts (3)
21-24: LGTM! Good fallback strategy.The translation function correctly returns the key when a translation is missing, which helps identify untranslated strings during development.
32-56: LGTM! Well-designed language detection.The priority chain is logical and properly handles SSR environments with
typeof window !== 'undefined'checks. ThestartsWith('ja')approach correctly matches regional variants likeja-JP.
62-66: LGTM!Proper window check for SSR safety, consistent with the detection logic.
app/problems/index.ts (3)
5-26: LGTM! Type definitions align with the design spec.The type hierarchy is clean and matches the requirements from BASIC.md. The
descriptionfield correctly supports both Japanese and English.
34-38: LGTM! Appropriate stub for basic setup.The TODO comment clearly indicates this will be implemented in the
feature/problem-loaderbranch, which aligns with the phased implementation plan from BASIC.md.
46-58: LGTM! Correctly implements combo scoring.The multiplier logic accurately matches the specification from BASIC.md:
- Combo 1: ×1.0
- Combo 2: ×1.2
- Combo 3: ×1.5
- Combo 4+: ×2.0
Using
Math.floorensures consistent integer scores.app/routes.ts (1)
1-3: LGTM!Quote normalization is consistent with the project-wide formatting standards.
README.md (1)
42-61: LGTM! Documentation improvements enhance usability.The addition of bash code blocks around CLI commands improves readability and makes the commands easily copy-pastable for developers.
package.json (2)
13-16: LGTM! Well-structured linting and formatting scripts.The new scripts follow common conventions and provide both check and fix operations for linting and formatting.
26-37: No current security vulnerabilities detected.The security advisory check found one historical ReDoS vulnerability in eslint versions < 4.18.2 (published February 2021), but the package.json specifies eslint@^9.18.0, which is unaffected. All other packages returned no vulnerabilities. The specified versions are secure.
app/root.tsx (1)
1-73: LGTM! Consistent quote style standardization.The systematic conversion from double quotes to single quotes aligns with the project's new Prettier configuration and improves code consistency.
app/welcome/welcome.tsx (1)
1-82: LGTM! Formatting improvements align with project standards.The quote style changes and JSX formatting improvements are consistent with the new Prettier configuration without altering any behavior.
app/routes/home.tsx (1)
1-17: LGTM! Good use of naming convention for unused parameters.The quote style changes are consistent with project formatting standards, and renaming the unused parameter to
_argsfollows the convention of prefixing unused variables with an underscore.
All dev/prod builds are working correctly.
