This roadmap is designed for **100% hands-on learning**. You will write all the code yourself step-by-step. Each task provides the exact concept explanation, file location, structural specifications, code snippet reference, and verification steps.\n4: \n5: ---\n6: \n7: ## Overview of Architectural Layers\n8: \n9: ```\n10: ┌─────────────────────────────────────────────────────────┐\n11: │ Frontend Layer │\n12: │ - App Layout (layout.tsx) │\n13: │ - Task Board & Filters (page.tsx, TaskFilterToolbar) │\n14: │ - Task Card & Badges (TaskCard.tsx, Overdue Indicator) │\n15: │ - Creation & Edit Modals (TaskForm, TaskEditModal) │\n16: └────────────────────────────┬────────────────────────────┘\n17: │ Server Actions / Form Submissions\n18: ┌────────────────────────────▼────────────────────────────┐\n19: │ Backend Layer │\n20: │ - Server Actions (src/app/actions.ts) │\n21: │ - Path Revalidation (revalidatePath('/')) │\n22: └────────────────────────────┬────────────────────────────┘\n23: │ Direct Function Calls\n24: ┌────────────────────────────▼────────────────────────────┐\n25: │ Data Access Layer │\n26: │ - Task Repository (src/lib/tasks.ts) │\n27: │ - Dynamic Overdue Derivation (`isOverdue()`) │\n28: │ - SQLite Database Connection (src/lib/db.ts) │\n29: └────────────────────────────┬────────────────────────────┘\n30: │ SQL Queries (better-sqlite3)\n31: ┌────────────────────────────▼────────────────────────────┐\n32: │ SQLite Database │\n33: │ - File: `todo.db` (Local Persistence) │\n34: └─────────────────────────────────────────────────────────┘\n35: ```\n36: \n37: ---\n38: \n39: ## 🛠️ Module 0: Workspace Setup & Git Baseline\n40: \n41: ### Task 0.1: Initialize Next.js Project\n42: - **Concept**: Next.js App Router uses file-system based routing and React Server Components.\n43: - **Action**: Run the Next.js initialization command in the project root.\n44: - **Command**:\n45: ```bash\n46: npx -y create-next-app@latest ./ --typescript --tailwind --eslint --app --src-dir --import-alias \"@/*\" --use-npm\n47: ```\n48: - **Checkpoint**: Ensure `src/app/page.tsx` and `package.json` are created.\n49: \n50: ### Task 0.2: Install SQLite Dependency\n51: - **Concept**:\n52: - `better-sqlite3`: Synchronous C-based SQLite driver for Node.js.\n53: - `@types/better-sqlite3`: TypeScript definitions for auto-completion.\n54: - **Action**: Install production and dev dependencies.\n55: - **Command**:\n56: ```bash\n57: npm install better-sqlite3\n58: npm install -D @types/better-sqlite3\n59: ```\n60: - **Checkpoint**: Check `package.json` to verify `better-sqlite3` is listed under `dependencies`.\n61: \n62: ### Task 0.3: Git Commit #1 - Initial Project Baseline\n63: - **Git Command**:\n64: ```bash\n65: git add .\n66: git commit -m \"chore: initialize Next.js app with SQLite setup\"\n67: ```\n68: \n69: ---\n70: \n71: ## 🗄️ Module 1: Data Layer & Database (SQLite)\n72: \n73: ### Task 1.1: Database Schema & Migration (`src/lib/db.ts`)\n74: - **Concept**:\n75: - SQLite column constraints: `TEXT`, `INTEGER PRIMARY KEY AUTOINCREMENT`.\n76: - `CHECK` constraint: Restricts `status` to `'Todo'`, `'In-Progress'`, `'Complete'`.\n77: - Archiving: `is_archived` stored as `INTEGER DEFAULT 0` (0 = active, 1 = archived).\n78: - **Target File**: [src/lib/db.ts](file:///c:/Users/mahla/critical_projects/SDP_Lab_1_To-do-app/src/lib/db.ts)\n79: - **Instructions**: Create `src/lib/db.ts` to initialize SQLite connection and create the `tasks` table if it doesn't exist.\n80: - **Code to Write**:\n81: ```typescript\n82: import Database from 'better-sqlite3';\n83: import path from 'path';\n84: \n85: const dbPath = path.join(process.cwd(), 'todo.db');\n86: const db = new Database(dbPath);\n87: \n88: // Initialize Schema\n89: db.exec(`\n90: CREATE TABLE IF NOT EXISTS tasks (\n91: id INTEGER PRIMARY KEY AUTOINCREMENT,\n92: title TEXT NOT NULL,\n93: description TEXT,\n94: due_date TEXT NOT NULL,\n95: topic TEXT NOT NULL,\n96: status TEXT CHECK(status IN ('Todo', 'In-Progress', 'Complete')) NOT NULL DEFAULT 'Todo',\n97: is_archived INTEGER DEFAULT 0,\n98: created_at DATETIME DEFAULT CURRENT_TIMESTAMP\n99: )\n100: `);\n101: \n102: export default db;\n103: ```\n104: \n105: ### Task 1.2: Type Definitions & Overdue Derived Property (`src/lib/types.ts`)\n106: - **Concept**:\n107: - **Rubric Rule**: Overdue state **MUST NOT** be stored as a column or status. It must be computed at read-time.\n108: - Overdue Rule: `due_date < current_date` AND `status !== 'Complete'` AND `is_archived === 0`.\n109: - **Target File**: [src/lib/types.ts](file:///c:/Users/mahla/critical_projects/SDP_Lab_1_To-do-app/src/lib/types.ts)\n110: - **Instructions**: Define TypeScript interfaces and helper functions.\n111: - **Code to Write**:\n112: ```typescript\n113: export type TaskStatus = 'Todo' | 'In-Progress' | 'Complete';\n114: \n115: export interface Task {\n116: id: number;\n117: title: string;\n118: description: string;\n119: due_date: string; // ISO Format YYYY-MM-DD\n120: topic: string;\n121: status: TaskStatus;\n122: is_archived: number; // 0 or 1\n123: created_at: string;\n124: is_overdue?: boolean; // Derived field\n125: }\n126: \n127: export function computeIsOverdue(dueDateStr: string, status: TaskStatus): boolean {\n128: if (status === 'Complete') return false;\n129: const today = new Date().toISOString().split('T')[0];\n130: return dueDateStr < today;\n131: }\n132: ```\n133: \n134: ### Task 1.3: Data Access Layer Functions (`src/lib/tasks.ts`)\n135: - **Concept**: SQL CRUD operations (`SELECT`, `INSERT`, `UPDATE`). Archiving sets `is_archived = 1`.\n136: - **Target File**: [src/lib/tasks.ts](file:///c:/Users/mahla/critical_projects/SDP_Lab_1_To-do-app/src/lib/tasks.ts)\n137: - **Instructions**: Write SQL prepared statements for fetching, creating, updating, and archiving tasks.\n138: - **Code to Write**:\n139: ```typescript\n140: import db from './db';\n141: import { Task, computeIsOverdue, TaskStatus } from './types';\n142: \n143: export function getTasks(options?: { sortBy?: 'topic' | 'status' | 'due_date'; includeArchived?: boolean }): Task[] {\n144: const includeArchived = options?.includeArchived ?? false;\n145: const sortBy = options?.sortBy ??

Because `CREATE TABLE IF NOT EXISTS` only executes if the table does *not* exist, editing `db.ts` alone will **not** automatically update or migrate an existing `todo.db` table.\n\n---\n\n### 🛠️ Step-by-Step Fix Guide\n\nPlease follow these steps to update your database schema and reset the local database:\n\n#### Step 1: Update Database Schema in [src/lib/db.ts](file:///c:/Users/mahla/critical_projects/SDP_Lab_1_To-do-app/src/lib/db.ts)\n\nOpen [src/lib/db.ts](file:///c:/Users/mahla/critical_projects/SDP_Lab_1_To-do-app/src/lib/db.ts) and update the `CREATE TABLE` query to include `description TEXT`, match `is_archived` (lowercase), and align `status` values (`'Todo'`):\n\n```typescript\nimport Database from 'better-sqlite3';\nimport path from 'path';\n\nconst dbPath = path.join(process.cwd(), 'todo.db');\nconst db = new Database(dbPath);\n\n// Initialise the database schema\ndb.exec(\n `\n CREATE TABLE IF NOT EXISTS tasks (\n id INTEGER PRIMARY KEY AUTOINCREMENT,\n title TEXT NOT NULL,\n description TEXT,\n due_date TEXT NOT NULL,\n topic TEXT NOT NULL,\n status TEXT CHECK(status IN ('Todo','In-Progress','Complete')) NOT NULL DEFAULT 'Todo',\n created_at TIMESTAMP DEFAULT CURRENT_TIMESTAMP,\n is_archived BOOLEAN NOT NULL DEFAULT 0\n )\n `\n);\n\nexport default db;\n```\n\n---\n\n#### Step 2: Delete the Existing Database File\n\nDelete the old `todo.db` file from your project root so SQLite creates a new database with the correct columns when the server runs.\n\nIn your terminal, run:\n```powershell\nRemove-Item todo.db\n```\n*(or delete `todo.db` directly in your file explorer).*\n\n---\n\n#### Step 3: Align Status Fallback in [src/lib/actions.ts](file:///c:/Users/mahla/critical_projects/SDP_Lab_1_To-do-app/src/lib/actions.ts)\n\nIn [src/lib/actions.ts](file:///c:/Users/mahla/critical_projects/SDP_Lab_1_To-do-app/src/lib/actions.ts#L12), change `'To-Do'` to `'Todo'` so it matches the `TaskStatus` type definition in [types.ts](file:///c:/Users/mahla/critical_projects/SDP_Lab_1_To-do-app/src/lib/types.ts#L1) and the SQLite `CHECK` constraint:\n\n```typescript\n// In src/lib/actions.ts\nconst status = (formData.get('status') as TaskStatus) || 'Todo';\n```\n\n---\n\n### 💡 Verification\n\n1. Restart your Next.js dev server (`npm run dev`).\n2. Navigate to your app in the browser and try adding a task again.\n3. The task should now be inserted cleanly into SQLite without errors!\n\n> 📘 **Updated Learning Guide**:\n> A troubleshooting reference has also been updated in [TASKS.md](file:///c:/Users/mahla/critical_projects/SDP_Lab_1_To-do-app/resources/learning_guides/TASKS.md#L101-L109) for future reference.","thinking":"**Drafting A Pedagogical Response**\n\nOkay, I'm currently focused on structuring a step-by-step explanation.

Your app will run and function normally.\n\n2. **Remove the extra parent lockfile**:\n If you accidentally ran `npm install` in `C:\\Users\\mahla\\` or `C:\\Users\\mahla\\critical_projects\\`, delete the extra `package-lock.json` file in that outer folder.\n\n3. **Explicitly set root directory in [next.config.ts](file:///c:/Users/mahla/critical_projects/SDP_Lab_1_To-do-app/next.config.ts)**:\n If you want to silence the warning, you can tell Next.js to treat your project folder as the strict root:\n ```typescript\n import type { NextConfig } from \"next\";\n\n const nextConfig: NextConfig = {\n outputFileTracingRoot: __dirname,\n };\n\n export default nextConfig;\n ```","thinking":"**Analyzing the Inquiry**\n\nI'm now zeroing in on the user's question about a warning. I've noted the specific terminal reference, `@`, and am cross-referencing this with the terminal buffer content. I am expecting some sort of warning in the nextjs documentation link.\n\n\n"}
