Installation

$ npm install react-dyn-tabs --save

or

$ yarn add react-dyn-tabs

Basic Example

import React from 'react';
import 'react-dyn-tabs/style/react-dyn-tabs.css';
import 'react-dyn-tabs/themes/react-dyn-tabs-card.css';
import useDynTabs from 'react-dyn-tabs';

export default () => {
  const options = {
    tabs: [
      {
        id: '1',
        title: 'tab 1',
        panelComponent: (porps) => <p> panel 1 </p>,
      },
      {
        id: '2',
        title: 'tab 2',
        panelComponent: (porps) => <p> panel 2 </p>,
      },
    ],
    selectedTabID: '1',
  };
  const [TabList, PanelList] = useDynTabs(options);
  return (
    <>
      <TabList></TabList>
      <PanelList></PanelList>
    </>
  );
};

Simple manipulation

import React from 'react';
import 'react-dyn-tabs/style/scss/react-dyn-tabs.scss';
import 'react-dyn-tabs/themes/scss/react-dyn-tabs-card.scss';
import useDynTabs from 'react-dyn-tabs';

export default () => {
  const options = {
    tabs: [
      {
        id: '1',
        title: 'tab1',
        panelComponent: (porps) => <p> panel 1 </p>,
      },
      {
        id: '2',
        title: 'tab2',
        panelComponent: (porps) => <p> panel 2 </p>,
      },
    ],
    selectedTabID: '1',
  };
  let _instance;
  const [TabList, PanelList, ready] = useDynTabs(options);
  ready((instance) => {
    _instance = instance;
  });
  const addTab3 = function () {
    // open tab 3
    _instance.open({id: '3', title: 'Tab 3', panelComponent: (porps) => <p> panel 3 </p>}).then(() => {
      console.log('tab 3 is open');
    });
    // switch to tab 3
    _instance.select('3').then(() => {
      console.log('tab 3 is selected');
    });
  };
  return (
    <>
      <button onClick={addTab3}>Add tab 3</button>
      <TabList></TabList>
      <PanelList></PanelList>
    </>
  );
};

NOTE :

• Tabs can't be manipulated safely before the first render, use ready() to access the instance object, ready accepts a function as its parameter and calls it when tabs are mounted.

• ready function identity is stable and won’t change on re-renders.

Options

const [TabList, PanelList, ready] = useDynTabs({
  tabs: [
    {
      id: '1',
      title: 'home',

      closable: true,
      panelComponent: (porps) => <p> home content </p>,
    },
    {
      id: '2',
      title: 'contact',
      tooltip: 'contact',
      disable: true,
      closable: false,

});

direction

Example

const [TabList, PanelList, ready] = useDynTabs({direction: 'rtl'});

tabComponent

Example

const [TabList, PanelList, ready] = useDynTabs({
  tabComponent: (props) => {
    const {id, isSelected, api: instance} = props;
    return (
      <button {...props.tabProps}>
        {props.children}
        {props.iconProps && <span {...props.iconProps}></span>}
      </button>
    );
  },
});

defaultPanelComponent

const [TabList, PanelList, ready] = useDynTabs({
  beforeClose: function (e, id) {
    console.log('[beforeClose]');
    return true;

Return value : Promise

Parameters:

• id: string

Example

if (instance.isSelected('1') == false) {
  instance.select('1').then(({currentData, instance}) => {
    console.log('tab 1 is selected');

getOption

Parameters:

• optionName : String

Example

const direction = instance.getOption('direction');
const onSelect = instance.getOption('onSelect');

setOption

You can use this method for setting all options except selectedTabID and tabs options.

For re-rendering immediately after this function, you should call refresh method after it.

Return value : instance object

Parameters:

• optionName : String
• optionValue : string|boolean|object|function

Example

instance.setOption('direction', 'rtl');
instance.setOption('onSelect', () => {});
instance.setOption('beforeSelect', () => false);

setTab

set tabData by id. for re-rendering immediately after this function, you should call refresh method after it.

Return value : instance

Parameters:

• tab id : String
• source object : containing the properties you want to apply

Example

instance.setTab('home', {disable: true});
instance.setTab('contact', {closable: false, panelComponent: (props) => <p>contact panel</p>});

on

Attach an event handler function for one event.

Return value : instance

Parameters:

• event Name : String (can be either of onFirstSelect|onSelect|onClose|onOpen|onInit|onChange|onDestroy)
• handler : function

Example

const handler = React.useCallback(function (params) {
  const {currentSelectedTabId, previousSelectedTabId} = params;
}, []);
instance.on('onSelect', handler);

one

Attach a handler to an event. The handler is executed at most once.

Return value : instance

Parameters:

  instance.off('onSelect', handler);
};

getData

get a copy of data

Return value : Object

Example

const {selectedTabID, openTabIDs} = instance.getData();

NOTE :

• getCopyData function is an older version of getData function and it is enabled by default so that existing users do not have to change their code. You are free to use both conventions.

getPreviousData

get a copy of data in previous render

Return value : Object

Example

const {selectedTabID, openTabIDs} = instance.getPreviousData();

NOTE :

• getCopyPerviousData function is an older version of getPreviousData function and it is enabled by default so that existing users do not have to change their code. You are free to use both conventions.

sort

Useful for sorting tabs manually.

Triggers onInit event.

Return value : Promise

Parameters:

• Array of all tabs IDs

Example

const {openTabIDs} = instance.getData();
instance.sort(openTabIDs.reverse()).then(({currentData, instance}) => {
  console.log('sorting tabs has finished');
});

tabData

Example

const tabData = {
  id: 'contactID',
  title: 'contactTitle',
  tooltip: 'contactTooltip',
  disable: true,
  lazy: true,
  iconClass: 'fa fa-home',
  closable: false,
  panelComponent: (porps) => <p> contact content </p>,
};
const [TabList, PanelList, ready] = useDynTabs({tabs: [tabData]});
// or
if (instance.isOpen(tabData.id) == false) {
  instance.open(tabData).then(() => {});
}

Lazy Loading

Defer loading of tab content until the tab is activated

Example 1

const Panel3 = React.lazy(() => import('./components/panel3.js'));
function LazyLoadingPanel3(porps) {
  return (
    <Suspense fallback={<div>Loading...</div>}>
      <Panel3 {...porps}></Panel3>
    </Suspense>
  );
}
useDynTabs({
  tabs: [
    {id: '1', title: 'eager loading tab 1', panelComponent: <p>panel 1</p>},
    {id: '2', title: 'eager loading tab 2', lazy: true, panelComponent: <p>panel 2</p>},
    {id: '3', title: 'lazy loading tab 3', lazy: true, panelComponent: LazyLoadingPanel3},
  ],
  selectedTabID: '1',
});

NOTE :

• panel 1 is eagerly loaded and rendered.
• panel 2 is eagerly loaded but will not be rendered until tab 2 is activated.
• panel 3 will not be loaded and rendered until tab 3 is activated.

Example 2 ( using onFirstSelect event )

useDynTabs({
  tabs: [
    {id: '1', title: 'eager loading tab 1', panelComponent: <p>panel 1</p>},
    {id: '2', title: 'eager loading tab 2', lazy: true, panelComponent: <p>panel 2</p>},
    {id: '3', title: 'lazy loading tab 3', lazy: true},
  ],
  selectedTabID: '1',
  defaultPanelComponent: function DefaultPanel() {
    return <div>loading...</div>;
  },
  onFirstSelect: function ({currentSelectedTabId}) {
    const instance = this;
    if (currentSelectedTabId === '3') {
      import('path to/panel3.js').then((defaultExportedModule) => {
        const Panel3 = defaultExportedModule.default;
        instance.setTab('3', {panelComponent: Panel3});
        instance.refresh();
      });
    }
  },
});

Styling

react-dyn-tabs does not include any style loading by default. Default stylesheets and themes are provided and can be included in your application if desired.

import 'react-dyn-tabs/style/react-dyn-tabs.min.css';
// or import 'react-dyn-tabs/style/scss/react-dyn-tabs.scss';
import 'react-dyn-tabs/themes/react-dyn-tabs-card.min.css';
// or import 'react-dyn-tabs/themes/scss/react-dyn-tabs-card.scss';

NOTE :

You can find other themes at themes folder and multiple themes example at example/multi-themes-example folder.

Caveats

• Some actions like open, select, close and refresh cause re-rendering, and using them immediately after calling useDynTabs hook will create an infinite loop and other bugs that most likely you don't want to cause. you should use them inside event listeners or subscriptions.

• Do not use setState inside the onInit callback because it leads to an infinite loop.

Deprecated features

These deprecated features can still be used, but should be used with caution because they are expected to be removed entirely sometime in the future. You should work to remove their use from your code.

• Third element of returned array by useDynTabs hook should not be used as an object, it is no longer recommended and only be kept for backwards compatibility purposes, it should be used as a function.

• First parameter of onSelect function is an object and has perviousSelectedTabId property which is deprecated. you should use previousSelectedTabId property instead of perviousSelectedTabId property.

• First parameter of onChange function is an object and has perviousData property which is deprecated. you should use previousData property instead of perviousData property.
