Flowforge Development

When to Use This Skill

Use when:

• Creating Kanban board interfaces for Eloquent models
• Configuring board columns, cards, and actions
• Implementing drag-and-drop with position management
• Building Filament board pages or standalone Livewire boards
• Troubleshooting position column issues

Quick Start

1. Add Position Column to Model

use Illuminate\Database\Schema\Blueprint;

Schema::table('tasks', function (Blueprint $table) {
    $table->flowforgePositionColumn(); // DECIMAL(20,10) nullable
    $table->unique(['status', 'position']);
});

2. Create Board Page

php artisan flowforge:make-board TaskBoard

3. Configure the Board

use Relaticle\Flowforge\BoardPage;
use Relaticle\Flowforge\Board;
use Relaticle\Flowforge\Column;

class TaskBoard extends BoardPage
{
    protected static ?string $navigationIcon = 'heroicon-o-view-columns';

    public function board(Board $board): Board
    {
        return $board
            ->query(Task::query())
            ->columnIdentifier('status')
            ->positionIdentifier('position')
            ->recordTitleAttribute('title')
            ->columns([
                Column::make('todo', 'To Do')
                    ->icon('heroicon-o-clipboard'),
                Column::make('in_progress', 'In Progress')
                    ->icon('heroicon-o-play'),
                Column::make('done', 'Done')
                    ->icon('heroicon-o-check'),
            ]);
    }
}

Integration Patterns

Filament Standard Page

use Relaticle\Flowforge\BoardPage;

class TaskBoard extends BoardPage
{
    protected static ?string $navigationIcon = 'heroicon-o-view-columns';
    protected static ?string $navigationGroup = 'Tasks';

    public function board(Board $board): Board
    {
        return $board
            ->query(Task::query()->where('team_id', auth()->user()->team_id))
            ->columnIdentifier('status')
            ->positionIdentifier('position')
            ->columns([...]);
    }
}

Filament Resource Page

use Relaticle\Flowforge\BoardResourcePage;

class TaskBoardPage extends BoardResourcePage
{
    protected static string $resource = TaskResource::class;

    public function board(Board $board): Board
    {
        return $board
            ->query($this->getResource()::getEloquentQuery())
            ->columnIdentifier('status')
            ->positionIdentifier('position')
            ->columns([...]);
    }
}

Register in resource:

public static function getPages(): array
{
    return [
        'index' => Pages\ListTasks::route('/'),
        'board' => Pages\TaskBoardPage::route('/board'),
    ];
}

Standalone Livewire Component

use Livewire\Component;
use Relaticle\Flowforge\Board;
use Relaticle\Flowforge\Contracts\HasBoard;
use Relaticle\Flowforge\Concerns\InteractsWithBoard;

class TaskBoard extends Component implements HasBoard
{
    use InteractsWithBoard;

    public function board(Board $board): Board
    {
        return $board
            ->query(Task::query())
            ->columnIdentifier('status')
            ->positionIdentifier('position')
            ->columns([...]);
    }

    public function render()
    {
        return view('livewire.task-board');
    }
}

Blade view:

<div>
    {{ $this->board }}
</div>

Board Configuration

Columns

use Relaticle\Flowforge\Column;

->columns([
    Column::make('backlog', 'Backlog')
        ->icon('heroicon-o-inbox')
        ->color('gray'),

    Column::make('todo', 'To Do')
        ->icon('heroicon-o-clipboard')
        ->color('info'),

    Column::make('in_progress', 'In Progress')
        ->icon('heroicon-o-play')
        ->color('warning'),

    Column::make('review', 'Review')
        ->icon('heroicon-o-eye')
        ->color('primary'),

    Column::make('done', 'Done')
        ->icon('heroicon-o-check-circle')
        ->color('success'),
])

Card Schema

Use Filament's Schema builder for rich card layouts:

use Filament\Infolists\Components\TextEntry;
use Filament\Infolists\Components\ImageEntry;
use Filament\Schemas\Components\Grid;

->cardSchema([
    Grid::make(2)
        ->schema([
            TextEntry::make('title')
                ->weight('bold'),
            TextEntry::make('priority')
                ->badge()
                ->color(fn ($state) => match ($state) {
                    'high' => 'danger',
                    'medium' => 'warning',
                    default => 'gray',
                }),
        ]),
    TextEntry::make('assignee.name')
        ->icon('heroicon-o-user'),
    TextEntry::make('due_date')
        ->date()
        ->icon('heroicon-o-calendar'),
])

Pagination

->cardsPerColumn(20)           // Cards loaded initially
->cardsIncrement(10)           // Cards loaded on "Load More"

Search

->searchable(['title', 'description'])

Filters

use Filament\Tables\Filters\SelectFilter;
use Filament\Tables\Filters\TernaryFilter;

->filters([
    SelectFilter::make('priority')
        ->options([
            'low' => 'Low',
            'medium' => 'Medium',
            'high' => 'High',
        ]),
    SelectFilter::make('assignee_id')
        ->relationship('assignee', 'name')
        ->searchable()
        ->preload(),
    TernaryFilter::make('is_overdue')
        ->label('Overdue'),
])

Actions

Record Actions (per card):

use Filament\Actions\Action;
use Filament\Actions\EditAction;
use Filament\Actions\DeleteAction;

->recordActions([
    EditAction::make()
        ->url(fn ($record) => route('tasks.edit', $record)),
    Action::make('archive')
        ->icon('heroicon-o-archive-box')
        ->action(fn ($record) => $record->archive()),
    DeleteAction::make(),
])

Column Actions (per column header):

->columnActions([
    Action::make('add')
        ->icon('heroicon-o-plus')
        ->action(function (array $arguments) {
            // $arguments['column'] contains column identifier
            Task::create([
                'status' => $arguments['column'],
                'position' => DecimalPosition::forEmptyColumn(),
            ]);
        }),
])

Position Management

Flowforge uses DECIMAL(20,10) positions with BCMath precision for reliable ordering.

DecimalPosition Service

use Relaticle\Flowforge\Services\DecimalPosition;

// Position between two cards (includes cryptographic jitter)
$position = DecimalPosition::between($afterPosition, $beforePosition);

// Exact midpoint (deterministic, for testing)
$position = DecimalPosition::betweenExact($afterPosition, $beforePosition);

// Position before first card
$position = DecimalPosition::before($firstPosition);

// Position after last card
$position = DecimalPosition::after($lastPosition);

// Initial position for empty column
$position = DecimalPosition::forEmptyColumn();

// Smart positioning (handles nulls)
$position = DecimalPosition::calculate($afterPos, $beforePos);

// Check if rebalancing needed
if (DecimalPosition::needsRebalancing($posA, $posB)) {
    // Gap is < 0.0001
}

// Generate evenly-spaced sequence
$positions = DecimalPosition::generateSequence(count: 100);

Manual Card Movement

// In your Livewire component
public function moveCard(
    int|string $recordId,
    string $toColumn,
    ?string $afterRecordId = null,
    ?string $beforeRecordId = null
): void {
    // Parent handles position calculation and saving
    parent::moveCard($recordId, $toColumn, $afterRecordId, $beforeRecordId);

    // Add custom logic after move
    $this->dispatch('card-moved');
}

Artisan Commands

Generate Board

php artisan flowforge:make-board TaskBoard
php artisan flowforge:make-board TaskBoard --resource  # For resource page

Diagnose Position Issues

php artisan flowforge:diagnose-positions "App\Models\Task" status position

Checks for:

• Missing positions (NULL values)
• Duplicate positions within columns
• Position inversions
• Gaps too small for further insertions

Rebalance Positions

php artisan flowforge:rebalance-positions "App\Models\Task" status position
php artisan flowforge:rebalance-positions "App\Models\Task" status position --column=in_progress

Interactive Repair

php artisan flowforge:repair-positions "App\Models\Task" status position

Offers multiple repair strategies:

• Fill NULL positions
• Fix duplicates
• Rebalance specific columns
• Full rebalance

Configuration

Publish config:

php artisan vendor:publish --tag=flowforge-config

config/flowforge.php:

return [
    'columns' => [
        'default_limit' => 50,
    ],
    'kanban' => [
        'initial_cards_count' => 20,
        'cards_increment' => 10,
    ],
    'ui' => [
        'show_item_counts' => true,
    ],
];

Migration Pattern

use Illuminate\Database\Migrations\Migration;
use Illuminate\Database\Schema\Blueprint;
use Illuminate\Support\Facades\Schema;

return new class extends Migration
{
    public function up(): void
    {
        Schema::table('tasks', function (Blueprint $table) {
            $table->flowforgePositionColumn();
            $table->unique(['status', 'position']);
        });
    }
};

Important: The unique constraint on [column_identifier, position] is required for concurrent safety.

Common Patterns

Scoped Boards (Multi-tenancy)

public function board(Board $board): Board
{
    return $board
        ->query(Task::query()->where('team_id', auth()->user()->team_id))
        // ...
}

Dynamic Columns from Database

public function board(Board $board): Board
{
    $statuses = Status::ordered()->get();

    return $board
        ->query(Task::query())
        ->columnIdentifier('status_id')
        ->positionIdentifier('position')
        ->columns(
            $statuses->map(fn ($status) =>
                Column::make($status->id, $status->name)
                    ->icon($status->icon)
                    ->color($status->color)
            )->toArray()
        );
}

Eager Loading for Cards

public function board(Board $board): Board
{
    return $board
        ->query(Task::query()->with(['assignee', 'tags', 'project']))
        // ...
}

Custom Card Click Behavior

->recordActions([
    Action::make('view')
        ->url(fn ($record) => TaskResource::getUrl('view', ['record' => $record]))
        ->openUrlInNewTab(),
])

Requirements

• PHP 8.3+ with ext-bcmath
• Laravel 12+
• Filament 5.x
• Position column: DECIMAL(20,10) with unique constraint
