Pluggable components to add a trello-like kanban board to your application


Build Status npm version

Basic Demo

Edit react-trello-example

Features Showcase



alt tag

  • responsive and extensible
  • easily pluggable into existing react application
  • supports pagination when scrolling individual lanes
  • drag-and-drop on cards and lanes (compatible with touch devices)
  • edit functionality to add/delete cards
  • Custom templates to define lane and card appearance
  • event bus for triggering events externally (e.g.: adding or removing cards based on events coming from backend)

Getting Started

Install using npm or yarn

$ npm install --save react-trello


$ yarn add react-trello


The Board component takes a prop called data that contains all the details related to rendering the board. A sample data json is given here to illustrate the contract:

const data = {
  lanes: [
      id: 'lane1',
      title: 'Planned Tasks',
      label: '2/2',
      cards: [
        {id: 'Card1', title: 'Write Blog', description: 'Can AI make memes', label: '30 mins'},
        {id: 'Card2', title: 'Pay Rent', description: 'Transfer via NEFT', label: '5 mins', metadata: {sha: 'be312a1'}}
      id: 'lane2',
      title: 'Completed',
      label: '0/0',
      cards: []

The data is passed to the board component and that's it.

import React from 'react'
import Board from 'react-trello'

export default class App extends React.Component {
  render() {
    return <Board data={data} />

Refer to storybook for detailed examples:

Also refer to the sample project that uses react-trello as illustration:

onCardDelete function Called when a card is deleted: onCardDelete(cardId, laneId)
onLaneClick function Called when a lane is clicked: onLaneClick(laneId). Card clicks are not propagated to lane click event
laneSortFunction function Used to specify the logic to sort cards on a lane: laneSortFunction(card1, card2)
eventBusHandle function This is a special function that providers a publishHook to pass new events to the board. See details in Publish Events section

customCardLayout boolean Boolean to indicate a custom card template will be specified. Add the card component as child to Board
customLaneHeader element Pass custom lane header as react component to modify appearance
data object Actual board data in the form of json

newLaneTemplate node Pass a custom new lane template to add new lanes to a board (when board is editable)

Refer to stories folder for examples on many more options for customization.

Publish Events

When defining the board, it is possible to obtain a event hook to the component to publish new events later after the board has been rendered. Refer the example below:

let eventBus = undefined

const setEventBus = (handle) => {
  eventBus = handle
//To add a card
eventBus.publish({type: 'ADD_CARD', laneId: 'COMPLETED', card: {id: "M1", title: "Buy Milk", label: "15 mins", description: "Also set reminder"}})

//To remove a card
eventBus.publish({type: 'REMOVE_CARD', laneId: 'PLANNED', cardId: "M1"})

//To move a card from one lane to another. index specifies the position to move the card to in the target lane
eventBus.publish({type: 'MOVE_CARD', fromLaneId: 'PLANNED', toLaneId: 'WIP', cardId: 'Plan3', index: 0})

//To update the lanes
eventBus.publish({type: 'UPDATE_LANES', lanes: newLaneData})

<Board data={data} eventBusHandle={setEventBus}/>

The first event in the above example will move the card Buy Milk from the planned lane to completed lane. We expect that this library can be wired to a backend push api that can alter the state of the board in realtime.


There are two ways to apply styles to the library components including Board, Lane or Card:

  • Use the predefined css classnames attached to these elements that go by .react-trello-lane, .react-trello-card, .react-trello-board
  • You can also pass custom style attributes as part of data. Refer to the storybook for examples

Custom Card Styling

You can completely customize the look-and-feel of each card in any lane by passing in a custom component as child to the Board as seen below:

<Board data={data} customCardLayout>
  <CustomCard />

customCardLayout prop must be set to true for the custom card to be rendered

The json content for the card and the card template must agree on the props:

const CustomCard = props => {
  return (
          borderBottom: '1px solid #eee',
          paddingBottom: 6,
          marginBottom: 10,
          display: 'flex',
          flexDirection: 'row',
          justifyContent: 'space-between',
          color: props.cardColor
        <div style={{fontSize: 14, fontWeight: 'bold'}}>{props.title}</div>
        <div style={{fontSize: 11}}>{props.dueOn}</div>
      <div style={{fontSize: 12, color: '#BD3B36'}}>
        <div style={{color: '#4C4C4C', fontWeight: 'bold'}}>{props.subTitle}</div>
        <div style={{padding: '5px 0px'}}>
        <div style={{marginTop: 10, textAlign: 'center', color: props.cardColor, fontSize: 15, fontWeight: 'bold'}}>

const data = {
  lanes: [
      id: 'lane1',
      title: 'Planned Tasks',
      cards: [
          id: 'Card1',
          name: 'John Smith',
          dueOn: 'due in a day',
          subTitle: 'SMS received at 12:13pm today',
          body: 'Thanks. Please schedule me for an estimate on Monday.',
          escalationText: 'Escalated to OPS-ESCALATIONS!',
          cardColor: '#BD3B36',
          cardStyle: {borderRadius: 6, boxShadow: '0 0 6px 1px #BD3B36', marginBottom: 15}
          id: 'Card2',
          name: 'Card Weathers',
          dueOn: 'due now',
          subTitle: 'Email received at 1:14pm',
          body: 'Is the estimate free, and can someone call me soon?',
          escalationText: 'Escalated to Admin',
          cardColor: '#E08521',
          cardStyle: {borderRadius: 6, boxShadow: '0 0 6px 1px #E08521', marginBottom: 15}

Editable Board

It is possible to make the entire board editable by setting the editable prop to true. This switch prop will enable existing cards to be deleted and show a Add Card link at the bottom of each lane, clicking which will show an inline editable new card.

Check out the editable board story and its corresponding source code for more details.

Compatible Browsers

Tested to work with following browsers using Browserling:

  • Chrome 60 or above
  • Firefox 52 or above
  • Opera 51 or above
  • Safari 4.0 or above
  • Microsoft Edge 15 or above

Feature Wishlist

  • the prop onDataChange is a catch all callback that returns the entire board data when anything changes on the board. Micro-events like when a card is added or re-arranged should be possible too

Check the Milestones for this project to track when the above features will be implemented.
