# Util Functions Refactor Summary

## Overview

Reorganized the monolithic `util/api_proccesor.js` (419 lines) into a clean, domain-specific folder structure with one function per file.

**Note:** This is a pure refactor of functions that exist in main's `api_proccesor.js`. Functions from the `feat/graphql-curriculum-caching` branch (FCC Proper integration, challengeMap utilities) are preserved in the backup branch `refactor/organize-util-functions-with-fcc-proper` for later integration.

## Changes Made

### ✅ Preserved Original File

- **KEPT**: `util/api_proccesor.js` - Original monolithic file remains unchanged
- **NOTE**: Yes, it's misspelled as "proccesor" instead of "processor"
- This ensures if any issues arise, the original file is still there for reference

### ✅ New Folder Structure

```
util/
├── api_proccesor.js # Original (unchanged, will be removed after merge)
├── curriculum/ # Curriculum metadata & fetching (4 files)
│ ├── constants.js
│ ├── getAllTitlesAndDashedNamesSuperblockJSONArray.js
│ ├── getAllSuperblockTitlesAndDashedNames.js
│ └── getSuperblockTitlesInClassroomByIndex.js
├── dashboard/ # Dashboard data transformation (2 files)
│ ├── createSuperblockDashboardObject.js
│ └── sortSuperBlocks.js
├── student/ # Student progress & data (5 files)
│ ├── calculateProgress.js (3 functions)
│ │ • getTotalChallengesForSuperblocks
│ │ • getStudentProgressInSuperblock
│ │ • getStudentTotalChallengesCompletedInBlock
│ ├── checkIfStudentHasProgressDataForSuperblocksSelectedByTeacher.js
│ ├── extractTimestamps.js (2 functions)
│ │ • extractStudentCompletionTimestamps
│ │ • extractFilteredCompletionTimestamps
│ ├── fetchStudentData.js
│ └── getIndividualStudentData.js
└── legacy/ # Deprecated v9-incompatible (3 files)
├── getDashedNamesURLs.js
├── getNonDashedNamesURLs.js
└── getSuperBlockJsons.js
```

**Total:** 14 new organized files from 16 functions in the original monolithic file

### ✅ Files Modified (Only Import Changes)

**6 files updated** with new import paths (no logic changes):

1. `components/DetailsDashboard.js`
2. `components/DetailsDashboardList.js`
3. `components/dashtable_v2.js`
4. `pages/dashboard/[id].js`
5. `pages/dashboard/v2/[id].js`
6. `pages/dashboard/v2/details/[id]/[studentEmail].js`

**All changes**: Only import statements updated to point to new file locations

## Benefits

1. **Easy to Find**: Instead of searching through 419 lines, go directly to the file you need
2. **Clear Organization**: Related functions grouped by domain (curriculum, student, dashboard)
3. **No Breaking Changes**: Original file preserved, only imports updated
4. **Maintainability**: One function per file = easier to understand and modify
5. **Better Discoverability**: File names match function names exactly

## Testing

- ✅ ESLint: No errors
- ✅ Prettier: All files formatted
- ✅ Import Resolution: All imports validated
- ✅ Diff Review: Only import path changes, no logic modifications
- ✅ Comparison with main: Only functions from main's api_proccesor.js included

## Visual Reference

See `mermaid.md` for an interactive diagram showing:

- All organized folders and files
- Function dependencies
- Page/component imports
- Legacy function warnings
- Can be updated as needed.
