0 / 4 Steps Completed

Step 1

Prisma Schema & Column Indexing

3 key tasks

Create Column and Task models with order position indices.

Key Implementation Tasks

Define Column and Task schemas with integer order fields
Write database seed file populating initial columns
Run prisma db push to apply schema

prisma/schema.prisma

model Task {
  id          String   @id @default(cuid())
  title       String
  description String?
  order       Int
  columnId    String
  createdAt   DateTime @default(now())
}

Common Challenges & Debugging Solutions

Real issues students hit during development and how to troubleshoot them fast.

State Management

Card Jump Flickering UI on Drag End

Issue: Waiting for database responses before updating UI causes dragging cards to snap back temporarily.

Fix Solution:Implement Optimistic UI state updates immediately in client component state, rolling back only on API failure.

Hydration

@hello-pangea/dnd Strict Mode React 18 Errors

Issue: React 18 Strict Mode double-mounting causes drag-and-drop context initialization crashes.

Fix Solution:Disable strict mode for board route or wrap Droppable in a custom client side mounting check hook.

Database Connection

Database Order Index Gaps

Issue: Moving cards between columns leaves duplicate or non-sequential position indices.

Fix Solution:Re-index target column task array orders sequentially (0, 1, 2...) inside the onDragEnd handler before sending updates to backend.
