🛠 Install and usage

Since this project use Hooks, you have to install them:

react>=16.8.5

After, Install the lib on your project:

yarn add @lourenci/react-kanban

Import the lib and use it on your project:

import Board from '@lourenci/react-kanban'
import '@lourenci/react-kanban/dist/styles.css'

const board = {
  columns: [
    {
      id: 1,
      title: 'Backlog',
      cards: [
        {
          id: 1,
          title: 'Add card',
          description: 'Add capability to add a card in a column'
        },
      ]
    },
    {
      id: 2,
      title: 'Doing',
      cards: [
        {
          id: 2,
          title: 'Drag-n-drop support',
          description: 'Move a card between the columns'
        },
      ]
    }
  ]
}

<Board initialBoard={board} />

🔥 API

🕹 Controlled and Uncontrolled

When you need a better control over the board, you should stick with the controlled board. A controlled board means you need to deal with the board state yourself, you need to keep the state in your hands (component) and pass this state to the <Board />, we just reflect this state. This also means a little more of complexity, although we make available some helpers to deal with the board shape. You can read more in the React docs, here and here.

If you go with the controlled one, you need to pass your board through the children prop, otherwise you need to pass it through the initialBoard prop.

Helpers to work with the controlled board

We expose some APIs that you can import to help you to work with the controlled state. Those are the same APIs we use internally to manage the uncontrolled board. We really recommend you to use them, they are 100% unit tested and they don't do any side effect to your board state.

To use them, you just need to import them together with your board:

import Board, { addCard, addColumn, ... } from '@lourenci/react-kanban'

All the helpers you need to pass your board and they will return a new board to pass to your state:

import Board, { addColumn } from '@lourenci/react-kanban'
...
const [board, setBoard] = useState(initialBoard)
...
const newBoard = addColumn(board, newColumn)
setBoard(newBoard)
...
<Board>{board}</Board>

You can see the list of helpers in the end of the props documentation.

🔷 Shape of a board

{
  columns: [{
    id: ${unique-required-columnId},
    title: {$required-columnTitle**},
    cards: [{
      id: ${unique-required-cardId},
      title: ${required-cardTitle*}
      description: ${required-description*}
    }]
  }]
}

* The title and the description are required if you are using the card's default template. You can render your own card template through the renderCard prop.

** The title is required if you are using the column's default template. You can render your own column template through the renderColumnHeader prop.

Ex.:

const board = {
  columns: [{
    id: ${unique-required-columnId},
    title: ${columnTitle},
    cards: [{
      id: ${unique-required-cardId},
      dueDate: ${cardDueDate},

  renderCard={({ content }, { removeCard, dragging }) => (
    <YourCard dragging={dragging}>
      {content}
      <button type="button" onClick={removeCard}>Remove Card</button>
    </YourCard>
  )}

{ on: 'bottom' }: to add on the bottom of the column (default).

* It's unavailable when the board is controlled.

Ex.:

const board = {
  columns: [{
    id: ${unique-required-columnId},
    title: ${columnTitle},
    wip: ${wip},
    cards: [{

      description: ${required-cardDescription}
    }]
  }]
}

<Board
  renderColumnHeader={({ title }, { removeColumn, renameColumn, addCard }) => (
    <YourColumnHeader>

`allowAddColumn`

Allow the user to add a new column directly by the board.

`onNewColumnConfirm`

When the user confirms a new column through the default column adder template, this callback will be called with a draft of a column with the title typed by the user.

If your board is uncontrolled you must return the new column with its new id in this callback.

If your board is controlled use this to get the new column title.

Ex.:

function onColumnNew (newColumn) {
  const newColumn = { id: ${required-new-unique-columnId}, ...newColumn }
  return newColumn
}

<Board initialBoard={board} allowAddColumn onColumnNew={onColumnNew} />

When the user adds a new column through the default column adder template, this callback will be called passing the updated board and the new column.

This callback will not be called in an uncontrolled board.

`renderColumnAdder`

Arg	Description
`columnBag`	A bag with some helper functions

`columnBag`

function	Description
`addColumn*`	Call this function with a new column to add the new column

* It's unavailable when the board is controlled.

Ex.:

const ColumnAdder = ({ addColumn }) {
  return (
    <div onClick={()=> addColumn({id: ${required-new-unique-columnId}, title: 'Title', cards:[]})}>
      Add column
    </div>

💅🏻 Styling

You can either style all the board or import our style and override it with the styles you want:

`react-kanban-card`
`react-kanban-card-skeleton`
`react-kanban-card--dragging`
`react-kanban-card__description`
`react-kanban-card__title`
`react-kanban-column`
`react-kanban-card-adder-form`
`react-kanban-card-adder-button`
`react-kanban-card-adder-form__title`
`react-kanban-card-adder-form__description`
`react-kanban-card-adder-form__button`
`react-kanban-column-header`
`react-kanban-column-header__button`
`react-kanban-column-adder-button`

🧪 Tests

Unit

yarn test

Code coverage is saved in coverage folder. Open HTML report for example with

open coverage/lcov-report/index.html

End-to-end

Using Cypress test runner. Start dev server and open Cypress using

yarn dev

All tests are in the cypress/integration folder. These tests also collect code coverage and save in several formats in the coverage folder. Open HTML report

open coverage/lcov-report/index.html

Read Cypress code coverage guide

Note: to avoid inserting babel-plugin-istanbul twice during Jest tests, E2E tests run with NODE_ENV=cypress environment variable. The babel-plugin-istanbul plugin is included in .babelrc file only in the cypress Node environment, leaving the default Jest configuration during NODE_ENV=test the same.
