Dependencies & critical paths

Analyze task dependencies to identify the work that determines project duration. The planner returns earliest/latest times, total float, resource IDs, and critical indicators that your application can display beside a timeline.

What you configure

analyzeCriticalPath: Supply the task collection to the licensed planner.
durationMinutes / dependencyIds: Describe each task's duration and prerequisite task IDs.
resourceIds: Retain resource context in the analysis result when relevant.

Essential integration

This assumes the shared Quick start already provides premiumLicense and, for UI views, premiumCalendarOptions. Only the feature-specific setup is shown.

import { AdvancedResourcePlanner } from '@wts-calendar/core/advanced-resource-planning';

const planner = new AdvancedResourcePlanner({
  license: premiumLicense,
  timeZone: 'UTC',
  resources: [
    { id: 'design', title: 'Design studio', capacity: 2 },
    { id: 'engineering', title: 'Engineering', capacity: 4 },
  ],
  events: [
    {
      id: 'review',
      title: 'Design review',
      resourceId: 'design',
      start: '2026-09-07T09:00:00Z',
      end: '2026-09-07T10:30:00Z',
    },
  ],
});

export const analysis = planner.analyzeCriticalPath([
  { id: 'design', durationMinutes: 90 },
  {
    id: 'build',
    durationMinutes: 180,
    dependencyIds: ['design'],
    resourceIds: ['engineering'],
  },
  { id: 'inspect', durationMinutes: 45, dependencyIds: ['build'] },
  { id: 'notes', durationMinutes: 30, dependencyIds: ['design'] },
]);
console.table(analysis.tasks);
console.log(analysis.criticalPathIds, analysis.projectDurationMinutes);

Behavior and lifecycle

The result includes one deterministic critical path and per-task float information.
Cycles, unknown dependencies, duplicate IDs, and invalid durations fail before a result is returned.

Limits and responsibilities

Critical-path analysis does not automatically reschedule calendar events.
It is not a resource-leveling optimizer; task durations and dependencies are supplied by your application.
