Kanban Project Backend

Kanban Project App Backend Template
Visual Task Management and Workflow Customization

Q: What is a Kanban project backend?

A Kanban project backend is a BaaS schema and API for task management: boards, tasks, columns, and swimlanes.

Q: What does the Kanban Project template include?

It includes Board (name, description), Task (title, description, status), Column (name, order), and Swimlane (name, order), ER diagram, API playground, and an AI Agent prompt.

Q: Why use Back4app for a task management app?

Back4app provides managed database, auth, real-time queries, and flexible schema so you can ship task visualization, workflow customization, and task updates without running your own backend.

Q: How do I run queries for boards and tasks with Flutter?

Use the Board and Task classes to query and display boards and tasks, leveraging the Back4app SDK.

Q: How do I create a column with Next.js server actions?

Use a server action to create a Parse Object for Column with board pointers and order. Optionally validate in Cloud Code.

Q: Can React Native cache boards and tasks offline?

Yes. Enable Local Datastore and pin Board and Task results so users can browse saved boards and tasks without connectivity.

Q: How do I prevent duplicate tasks?

In Cloud Code beforeSave for Task, query existing tasks and reject if a duplicate exists.

Q: What is the best way to show boards and tasks on Android?

Query Board and Task classes to display boards and tasks, using the Back4app SDK for data management.

Q: How does the task update flow work end-to-end?

Users can create and move tasks, and the system updates in real-time using Live Queries for instant notifications.

A production-ready Kanban project backend on Back4app with boards, tasks, columns, and swimlanes. Includes ER diagram, data dictionary, JSON schema, API playground, and an AI Agent prompt for rapid bootstrap.

Overview

A task management product needs boards, tasks, columns, and swimlanes.

This template defines Board, Task, Column, and Swimlane with real-time features and ownership rules so teams can implement task management quickly.

Core Kanban Project Features

Every technology card in this hub uses the same Kanban project backend schema with Board, Task, Column, and Swimlane.

Board management

Board class stores name and description.

Task creation and management

Task class links title, description, and status.

Column organization

Column class stores name and order.

Swimlane logic

Swimlane class tracks task grouping with order.

Real-time task updates

Real-time updates for task changes.

Why Build Your Kanban Project Backend with Back4app?

Back4app gives you board, task, column, and swimlane primitives so your team can focus on workflow customization and task visualization instead of infrastructure.

•Board and task management: Board class with name and description fields and task class for task management supports visual task interactions.
•Column and swimlane features: Manage columns and swimlanes with customizable order and logic.
•Realtime + API flexibility: Use Live Queries for task updates while keeping REST and GraphQL available for every client.

Build and iterate on task management features quickly with one backend contract across all platforms.

Core Benefits

A task management backend that helps you iterate quickly without sacrificing structure.

Rapid task launch

Start from a complete board, task, and column schema rather than designing backend from zero.

Real-time collaboration support

Leverage real-time task updates and notifications for enhanced team collaboration.

Clear workflow customization

Manage task workflows with customizable states and swimlane logic.

Scalable permission model

Use ACL/CLP so only users can edit their boards and tasks, and manage workflow customization.

Task and column data

Store and aggregate tasks and columns for display and interaction without schema resets.

AI bootstrap workflow

Generate backend scaffolding and integration guidance fast with one structured prompt.

Build with AI Agent

Use the Back4app AI Agent to generate a real Kanban project app from this template, including frontend, backend, auth, and board, task, column, and swimlane flows.

Back4app AI Agent

Ready to build

Create a Kanban-style task management app backend on Back4app with this exact schema and behavior.

Schema:
1. Board: name (String, required), description (String); objectId, createdAt, updatedAt (system).
2. Task: title (String, required), description (String), status (String); objectId, createdAt, updatedAt (system).
3. Column: name (String, required), order (Number); objectId, createdAt, updatedAt (system).
4. Swimlane: name (String, required), order (Number); objectId, createdAt, updatedAt (system).

Security:
- Only the user can update/delete their boards. Only the creator can create/delete their tasks and columns. Use Cloud Code for validation.

Auth:
- Sign-up, login, logout.

Behavior:
- List boards, create tasks, organize columns, and manage swimlanes.

Deliver:
- Back4app app with schema, ACLs, CLPs; frontend for boards, tasks, columns, and swimlanes.
