Getting Started

Install using npm or yarn

``bash
$ npm install --save react-trello
`

or

`bash
$ yarn add react-trello
`

Usage

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:

`javascript
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', draggable: false},
{id: 'Card2', title: 'Pay Rent', description: 'Transfer via NEFT', label: '5 mins', metadata: {sha: 'be312a1'}}
]
},
{
id: 'lane2',
title: 'Completed',
label: '0/0',
cards: []
}
]
}
`

draggable property of Card object is true by default.

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

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

export default class App extends React.Component {
render() {
return
}
}
`

Refer to storybook for detailed examples: https://rcdexta.github.io/react-trello/

Also refer to the sample project that uses react-trello as illustration: https://github.com/rcdexta/react-trello-example

Use edge version of project (current master branch)

`bash
$ yarn add rcdexta/react-trello
`

and

`javascript
import Board from 'react-trello/src'
`

Upgrade

Breaking changes. Since version 2.2 these properties are removed: addLaneTitle, addCardLink, customLaneHeader, newCardTemplate, newLaneTemplate,
and customCardLayout with children element.

Follow upgrade instructions to make easy migration.

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

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.

Styling and customization

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

$3

Use the predefined css classnames attached to these elements that go by .react-trello-lane, .react-trello-card, .react-trello-board:

`css
.react-trello-lane {
border: 0;
background-color: initial;
}
`

$3

This method depends on used Card and Lane components.

`javascript
const data = {
lanes:
{
id: 'lane1',
title: 'Planned Tasks',
style: { backgroundColor: 'yellow' }, // Style of Lane
cardStyle: { backgroundColor: 'blue' } // Style of Card
...
};

style={{backgroundColor: 'red'}} // Style of BoardWrapper
data={data}
/>
`

Storybook example - [stories/Styling.story.js

$3

You can override any of used components (ether one or completery all)

`javascript
const components = {
GlobalStyle: MyGlobalStyle, // global style created with method createGlobalStyle of styled-components
LaneHeader: MyLaneHeader,
Card: MyCard,
AddCardLink: MyAddCardLink,
...
};


`

Total list of customizable components: src/components/index.js

Refer to components definitions to discover their properties list and types.

Refer more examples in storybook.

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:

`javascript
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 update a card
eventBus.publish({type: 'UPDATE_CARD', laneId: 'COMPLETED', card: {id: "M1", title: "Buy Milk (Updated)", label: "20 mins", description: "Also set reminder (Updated)"}})

//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})


`

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.

I18n and text translations

$3

Pass translation function to provide custom or localized texts:

`javascript

// If your translation table is flat
//
// For example: { 'placeholder.title': 'some text' }
const customTranslation = (key) => TRANSLATION_TABLE[key]

// If your translation table has nested hashes (provided translations table is it)
//
// For example: { 'placeholder': { 'title': 'some text' } }
import { createTranslate } from 'react-trello'
const customTranslation = createTranslate(TRANSLATION_TABLE)


`

List of available keys - locales/en/translation.json

$3

`javascript
import { withTranslation } from 'react-i18next';

const I18nBoard = withTranslation()(Board)
`
