  • Three Zoom levels : day, week, month
  • Fully customisable.
  • Support all CRUD operations.
  • Task and Link creation.

To watch a demo take a look at video that shows how to use the component.

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
onSelectItem item:Object This callback is trigger when an item is selected this can be a task or a link

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

Here is a full crud example: This demo illustrate how to do a simple application

Here is a fully working Redux demo

Paging is manage using the event onHorizonChange.The timeline component preload a certain date range of data, once the user start scrolling when the timeline realise that needs data for a new range, it trigger the onHorizonChange event. This method then can be use to support serverside paging or client filtering.

name params Descriptions
onHorizonChange start,end:Date This callback is trigger when the component is notifying that needs to load data for a new range of dates.

Here is a demo app that shows how to use onHorizonChange, to only display the relvant data for a period:

To customise the look and feel the react-timeline-gantt component provides a configuration object that can be pass as a property. Here is the structure of the config object :

	header:{ //Targert the time header containing the information month/day of the week, day and time.
		top:{//Tartget the month elements
			style:{backgroundColor:"#333333"} //The style applied to the month elements
		middle:{//Tartget elements displaying the day of week info
			style:{backgroundColor:"chocolate"}, //The style applied to the day of week elements
			selectedStyle:{backgroundColor:"#b13525"}//The style applied to the day of week elements when is selected
		bottom:{//Tartget elements displaying the day number or time 
			style:{background:"grey",fontSize:9},//the style tp be applied 
			selectedStyle:{backgroundColor:"#b13525",fontWeight:  'bold'}//the style tp be applied  when selected
	taskList:{//the right side task list
		title:{//The title od the task list
			label:"Projects",//The caption to display as title
			style:{backgroundColor:  '#333333',borderBottom:  'solid 1px silver',
				   color:  'white',textAlign:  'center'}//The style to be applied to the title
		task:{// The items inside the list diplaying the task
			style:{backgroundColor:  '#fbf9f9'}// the style to be applied
		verticalSeparator:{//the vertical seperator use to resize he width of the task list
			style:{backgroundColor:  '#333333',},//the style
			grip:{//the four square grip inside the vertical separator
				style:{backgroundColor:  '#cfcfcd'}//the style to be applied
	dataViewPort:{//The are where we display the task
		rows:{//the row constainting a task
			style:{backgroundColor:"#fbf9f9",borderBottom:'solid 0.5px #cfcfcd'}
		task:{the task itself
			showLabel:false,//If the task display the a lable
			style:{position:  'absolute',borderRadius:14,color:  'white',
			 selectedStyle:{}//the style tp be applied  when selected
	links:{//The link between two task

Once the object is defined we just need to pass the config object to the timeline config property.

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