Gantt Critical Path

JuanFlorez

Hi, i wanna ask if there's any way to get which tasks belong to the critical path??? (those that if delayed, will directly impact the completion date)

Thanks

Hello

There is no a specific api for this purpose but you can structure your tasks to include baseStart, start, baseEnd, end, and a status flag to indicate if the task is delayed. Here is an example of how you can define a task object:

const tasks = [
{
    id: 1,
    start: new Date(2024, 3, 2),
    end: new Date(2024, 3, 17),
	base_start: new Date(2024, 3, 2),
    base_end: new Date(2024, 3, 13),
    text: "Project planning",
    progress: 30,
    parent: 0,
    type: "summary",
    open: true,
    details: "Outline the project's scope and resources.",
  },
]

Then you can create a function to determine if a task is delayed based on the start and end date comparisons:

 const isDelayed = (task) => {
    return task.end > task.base_end; // You might want to adjust this logic
  };
