| 1 | +# TheNextLvl Documentation Website |
| 2 | + |
| 3 | +TheNextLvl documentation is a Next.js 15 application built with Fumadocs, TypeScript, and Tailwind CSS. It serves as the documentation site for TheNextLvl Minecraft server community plugins and services, accessible at https://thenextlvl.net. |

| 7 | +## Working Effectively |
| 8 | + |
| 9 | +### Bootstrap, Build, and Development |
| 10 | + |
| 11 | +- **CRITICAL**: Some commands have network dependencies that may fail in restricted environments |
| 12 | +- Install dependencies: |
| 13 | + - Preferred: `bun install` -- takes ~1-24 seconds. NEVER CANCEL. Set timeout to 120+ seconds. |
| 14 | + - Fallback: `npm install` -- takes ~71 seconds. NEVER CANCEL. Set timeout to 180+ seconds. |
| 15 | +- Development server: |
| 16 | + - `bun run dev` or `npm run dev` -- starts in ~1 second, runs on http://localhost:3000 |
| 17 | + - NEVER CANCEL: Development server runs indefinitely until stopped |
| 18 | +- Production build: |
| 19 | + - `bun run build` or `npm run build` |
| 20 | + - **WARNING**: Build fails in restricted network environments due to: |
| 21 | + 1. Google Fonts (fonts.gstatic.com) access required for Inter font |
| 22 | + 2. API calls to repo.thenextlvl.net for version information |
| 23 | + - Build takes ~20-30 seconds when network is available |
| 24 | + - If build fails with network errors, this is expected in sandboxed environments |
| 25 | + |
| 26 | +### Package Manager Setup |
| 27 | + |
| 28 | +- **Install Bun** (if not available): |
| 29 | + ```bash |
| 30 | + curl -fsSL https://bun.sh/install | bash |
| 31 | + source ~/.bashrc |
| 32 | + bun --version |
| 33 | + ``` |
| 34 | +- The project specifies `[email protected]` as the package manager in package.json |
| 35 | +- Node.js fallback is supported for all commands |
| 36 | + |
| 37 | +### Linting and Formatting |
| 38 | + |
| 39 | +- **Format code**: `bun run format` or `npm run format` -- takes ~1 second. Uses Prettier. |
| 40 | +- **Lint code**: `bunx next lint` -- takes ~3 seconds. NEVER CANCEL. Set timeout to 30+ seconds. |
| 41 | + - Note: Shows warnings about TypeScript version mismatch (expected) |
| 42 | + - May show img element and unused variable warnings (expected) |
| 43 | +- **CRITICAL**: Always run formatting and linting before pushing changes or CI will fail |
| 44 | + |
| 45 | +## Validation Scenarios |
| 46 | + |
| 47 | +### Manual Testing Requirements |
| 48 | + |
| 49 | +After making changes, ALWAYS perform these validation steps: |
| 50 | + |
| 51 | +1. **Start development server**: |
| 52 | + - Run `bun run dev` or `npm run dev` |
| 53 | + - Verify server starts on http://localhost:3000 in ~1 second |
| 54 | + - Test homepage loads: `curl -s http://localhost:3000 | head -10` |
| 55 | + - Verify you see HTML content starting with `<!DOCTYPE html>` |
| 56 | + |
| 57 | +2. **Test documentation pages**: |
| 58 | + - Navigate to http://localhost:3000/docs |
| 59 | + - **Note**: Pages may show 500 errors in restricted networks due to API calls - this is expected |
| 60 | + - In normal environments, verify navigation and content display works |
| 61 | + |
| 62 | +3. **Validate formatting and linting**: |
| 63 | + - Run `bun run format` or `npm run format` - should complete in ~1 second without errors |
| 64 | + - Run `bunx next lint` - should complete in ~3 seconds with minimal warnings only |
| 65 | + - Expected warnings: img element usage, unused variables (these are normal) |
| 66 | + |

| 92 | +### Key Files to Know |
| 93 | + |
| 94 | +- `src/lib/api.ts` - Contains API calls to repo.thenextlvl.net (causes network issues) |
| 95 | +- `src/app/layout.tsx` - Main app layout with Inter font from Google Fonts |
| 96 | +- `src/lib/source.ts` - Fumadocs content source configuration |
| 97 | +- `content/docs/` - All documentation content in MDX format |
| 98 | +- `.github/workflows/build.yml` - CI pipeline using Bun |
| 99 | + |
| 100 | +### Content System |
| 101 | + |
| 102 | +- Uses Fumadocs with MDX for documentation |
| 103 | +- Content lives in `content/docs/` directory |
| 104 | +- Each section has `meta.json` for navigation configuration |
| 105 | +- Some pages import `latestVersion` function from `src/lib/api.ts` for dynamic version display |
| 106 | + |
| 107 | +## Common Tasks and Troubleshooting |
| 108 | + |
| 109 | +### Network-Related Issues |
| 110 | + |
| 111 | +- **Google Fonts errors**: Expected in restricted environments. Font loading fails but app still functions. |
| 112 | +- **repo.thenextlvl.net errors**: API calls for version information fail in restricted networks. |
| 113 | +- **Workaround**: For testing, temporarily comment out font imports and API calls if needed. |
| 114 | + |
| 115 | +### Build Issues |
| 116 | + |
| 117 | +- If build fails with "fetch failed" errors, this indicates network restrictions |
| 118 | +- Development mode (`bun run dev`) works even when build fails |
| 119 | +- Production build requires internet access for fonts and API calls |
| 120 | + |
| 121 | +### Dependencies |
| 122 | + |
| 123 | +- Always use `bun install` when possible (much faster than npm) |
| 124 | +- If Bun unavailable, `npm install` works as fallback |
| 125 | +- No test suite exists - validation is done through manual testing |
| 126 | + |
| 127 | +### Making Content Changes |
| 128 | + |
| 129 | +- Edit MDX files in `content/docs/` directory |
| 130 | +- Changes are hot-reloaded in development mode |
| 131 | +- Some content files use `await latestVersion()` calls that require network access |
| 132 | +- Always test documentation navigation after content changes |
| 133 | + |
| 134 | +## CI/CD Integration |
| 135 | + |
| 136 | +### GitHub Actions |
| 137 | + |
| 138 | +- Workflow: `.github/workflows/build.yml` |
| 139 | +- Runs on: Ubuntu latest with Bun |
| 140 | +- Steps: checkout → setup bun → install dependencies → build |
| 141 | +- Environment variable: `NEXT_PUBLIC_BASE_URL: https://thenextlvl.net` |
| 142 | +- Build must pass for deployment |
| 143 | + |
| 144 | +### Pre-commit Checklist |
| 145 | + |
| 146 | +1. Run `bun run format` or `npm run format` - ensure all files formatted (~1 second) |
| 147 | +2. Run `bunx next lint` - check for linting issues (~3 seconds, warnings OK) |
| 148 | +3. Test development server starts: `bun run dev` or `npm run dev` (~1 second) |
| 149 | +4. Verify content changes display correctly at http://localhost:3000 |
| 150 | +5. Test homepage accessibility: `curl -s http://localhost:3000 | head -10` |
| 151 | +6. Check that new files follow existing patterns |
| 152 | + |
| 153 | +## Network Dependencies Summary |
| 154 | + |
| 155 | +- **Google Fonts**: Inter font family (fonts.gstatic.com) |
| 156 | +- **Version API**: repo.thenextlvl.net for plugin version info |
| 157 | +- **Expected failures**: Both may fail in sandboxed/restricted environments |
| 158 | +- **Impact**: Development server works, but production build may fail |
