Features



- Typescript out of box

- Many modes to control the behaviour of the selected tab.

- Easy to start with it takes you less than minute to start it up!

- Many features and so easy to customize

- Fully support for RTL (actually the reason why I built this component is because RTL)

- Fully accessible

- You can control and have access to everything inside it.

- Small sized 9.6k (gzipped: 3.9k)

- Great to use in navigation, menus and lists or any proper use for tabs

- Easy to style, you have the css file so you can edit it as you would like, and there are style and className props to all the elements used inside the package.

- You have access to all refs.

- And much more ..



What's new in V2?



- I rebuild the package from scratch with typescript to avoid the unnecessary bugs and to make it more elegant and easy to use with the typescript auto-complete.



  > Note: this's my first time using typescript so expect many bugs with types since i was interfering a lot of types to any, and because I dont have the proper internet, I couldnt search well for them -\_-.

  > But overall I think everything works fine!.



- I deleted the unnecessary code and made it more readable and clean.



- I deleted

selectedTabCoordinates and replaced it with getTabsBoundingClientRects function that returns DOMRect object for the tabsContainer and tab, and it's way performant comparing to the old selectedTabCoordinates

, it just runs when the scroll stops and when you switch to RTL.



- I renamed the two action

onRightBtnClick and onLeftBtnClick to onRightNavBtnClick and onLeftNavBtnClick





- I made the API and the enternals of the component more exposed to the developers who wants to use it (Please see the API table below to see all the new props), since I added about 15 new props including refs to all the elements inside the pacakge, and I added custom styles to style it as you want.



- I added new features to make the component more compatible with my new package  react-kfc-menu such as mode prop that controls the behavior of the selected tab scroll, now you can change the whole behavior of it with the new 4 modes I've added to it.



- I added

 component if you want to use tab panels with the tabs.



> I'm planning to add Swipeable component to make the TabScreens more interactive with drag and touch events on both, Desktop and mobile.



Please If you faced any bugs feel free to open an issue.
