Installation

npm install react-gantt-timeline

The component has the following dependencies: moment, react-sizeme

Getting started

The first thing to once the component has been install and all it dependencies is create the data that the timeline component consume.The time line has two data providers data and links.

Data :is an array of objects that contains the task to be shown. Each one of the object that are part of the array need to have the following compulsory fields

Property value Descriptions
id String/Number An unique identifier for the class
start Date The start date of the task
end Date The end date of the task
name String The name of the task to be diplayed
color (optional) String The color of the task to be diplayed

An example of data definition:

 let data=[ {id:1,start:new Date(), end:new Date()+1 ,name:'Demo Task 1'},
			{id:2,start:new Date(), end:new Date()+1 ,name:'Demo Task 2'}]

Links :is also an array of objects that contains links between task. Each one of the object that are part of the array need to have the following compulsory fields:

Property value Descriptions
id String/Number An unique identifier for the class
start String/Number The id of the start task
end String/Number The id of the end task

An example of data definition:

 let links=[ {id:1,start:1, end:2},
			{id:2,start:1, end:3}]

Once the data is define we just need to declare the component and populate it with both data providers.


<TimeLine  data={data} links={links}/>);

Here is the demo code:

Handling Inserts,Updates and Deletes

The React-timeline-gantt was build to be use under a Flux architecture, this means that the component should not be managing the state of the application, is up the store and only the store to modify the state of the application. What our component does is to give you callbacks to know when the component is asking for a change.

The TimeLine component is responsible for two things:

  • Updating task:Changing name ,start and end date
  • Creating Links

Adding,Deleting Task or links can be manage with logic outside the component.
For this reason the react-timeline-gantt component provides the following callbacks:

name params Descriptions
onCreateLink link:Object This callback is trigger when the component is notifying the creating of a link between two tasks
onUpdateTask task:Object,props:Object This callback is trigger when the component is notifying the updating of a Task, Sen the task we want to changes, and the properties we want to change

Here is a simple demo of how to handle updates task and link creation:

  • When you drag a task or resize an update will be triggered.
  • You can create a task by clicking in the black dot at the end of a task and drag and drop it to the beginning of another task.A demo of how it works can be seen here
