# rn-video-slider A dedicated progress slider for video player's custom user interfaces in React-Native. It can also be used in audio players because why not? 😎 Demonstration Buffer Demonstration Bubble Demonstration ## Why this module? - superior performance thanks to Reanimated library - clean and simple implementation that makes it easy to extend - integrated buffer indicator for online streams - fully written in Typescript - easiest way to use - RTL support ## Installation This module uses `react-native-reanimated` and `react-native-gesture-handler` as peer dependencies. make sure You have installed them correctly. You may also install `react-native-video`. Check out these links to proceed their installation process: - [reanimated installation](https://docs.swmansion.com/react-native-reanimated/docs/fundamentals/getting-started#installation) - [gesture-handler installation](https://docs.swmansion.com/react-native-gesture-handler/docs/fundamentals/installation) - [video installation](https://react-native-video.github.io/react-native-video/installation) Once you are done with above, add the main package with one of below commands: ### using npm ```sh npm i rn-video-slider ``` ### using yarn ```sh yarn add rn-video-slider ``` That will be it. ## Usage ```typescript jsx import {Dimensions} from "react-native"; import Slider, {SliderRef} from "rn-video-slider"; const ControlSet = () => { const sliderRef = React.createRef(); //call below function in video progress callback //sliderRef.current?.setProgress(0.5); const _onSlide = (value: number) => { //seek your video with value }; //this simply means 80% of screen's width const sliderWdith = Dimensions.get('window').width * 0.8; return ( ) } ``` **Note:** You can see the Component in action by cloning this repo and building its test app. Just head over to `testapp` directory, install the dependencies and run it on Android or IOS. ## Slider Properties Here is the list of properties that you can set or override. | Name | Type | Required | Default Value | Description | |:---------------------:|:---------------------:|:--------:|:---------------------:|----------------------------------------------------------------------------------------------------------------------| | width | number | Yes | undefined | width of slider track | | height | number | No | 3 | height of slider track | | thumbSize | number | No | 12 | diameter of sliding thumb | | thumbColor | string | No | #FFFFFF | color of sliding thumb | | thumbStyle | ViewStyle | No | undefined | style override for thumb view. It has higher priority than thumbSize and thumbColor. | | progressColor | string | No | #FFFFFF | color of progress indicator | | bufferProgressColor | string | No | rgba(255,255,255,0.5) | color of buffer progress indicator | | trackColor | string | No | rgba(255,255,255,0.2) | color of underlying view | | rootStyle | ViewStyle | No | undefined | style addon for root view | | isRTL | boolean | No | I18nManager.isRTL | overrides direction of movement. setting to "true" makes the slider animate from right to left. | | tapActive | boolean | No | true | activates tap gesture. when set to "true", onSlide function fires on receiving single taps. | | initialProgress | number | No | 0 | sets the initial progress value. | | bufferInitialProgress | number | No | 0 | sets the initial buffer progress value. | | bubbleContainerStyle | ViewStyle | No | 0 | style object that overrides default style of bubble container view which is absolutely positioned inside thumb view. | | bubbleVisibility | 'always' \| 'onTouch' | No | No | determines when bubble should be displayed | determines when bubble should show up | **Note:** Root view has a default padding equal to 10. Override it in root style if you need to. **Note2:** You can disable thumb shadow by passing appropriate thumbStyle. (`elevation: 0, shadowOpacity: 0`) ## Event properties Here is the list of events that slider fires. | Name | Params | Description | |:-------------:|:------:|---------------------------------------------------------------------------------------------------------------------------------------------| | onSlide | value | Called when the slider is being moved via a pan or tap gesture. It passes a "value" which is a number that changes from 0 to 1. | | onSlideStart | value | Called when one of tapping or sliding gestures start. It passes the current progress as "value". | | onSlideFinish | value | Called when one of tapping or sliding gestures finish. It passes the current progress as "value". | | renderBubble | value | Called when thumb is being held via touch gesture. It passes the current progress as "value". Use it to render hovering bubble above thumb. | ## Reference Methods Here is the list of methods that can be called via reference. | Name | Params | Description | |:-----------------:|:------:|----------------------------------------------------| | setProgress | value | Animates main progress slider based on given value | | setColdProgress | value | Sets main progress level without any animation | | setBufferProgress | value | Sets progress level of the buffer indicator | **Note:** progress values are a float from 0 to 1 ## How To Render Hovering Bubble You can either use the built-in bubble component or render your own. Read below to proceed with the built-in one. ### Example ```typescript jsx import {Dimensions} from "react-native"; //1. import the bubble import Slider, {Bubble} from "rn-video-slider"; const Example = () => { const sliderWdith = Dimensions.get('window').width * 0.8; //2. make a rendering function for it. // head over to `testapp/src/conveter.ts` to see the `progressToVideoTime` function const _renderBubble = (progress: number) => { return ; }; //3. use it return ( ) } ``` ### Bubble Properties | Name | Type | Required | Default Value | Description | |:-----------:|:-----------:|:--------:|:-------------:|----------------------------------------------------------------------------------------------------------| | `rootStyle` | `ViewStyle` | No | `undefined` | Custom style object for the bubble's root view | | `text` | `string` | Yes | `undefined` | Text to display at center of bubble (Usually it's video time for corresponding to the current progress.) | | `textStyle` | `TextStyle` | No | `undefined` | Custom style object for the bubble's text element | ## TODO list - [x] ~~add hovering bubble feature~~ - [x] ~~add in-code docs~~ - [x] ~~ensure fabric support~~ - [x] ~~more and better demo gifs~~ - [x] ~~cleanups and refactors~~ - [x] ~~bump test-app dependencies up~~ - [x] ~~write a better example~~ - [x] ~~fix delay between thumb and track while sliding fast~~ - [x] ~~implement tap to seek feature~~ - [x] ~~replace the deprecated `useAnimatedGestureHandler` with newer API~~ - [x] ~~add style prop for root view~~ ## Contributions If you have any idea to improve or fix something, open an issue and state it in details. You will always be welcomed. ## Compatability - `react-native-reanimated`: `2.x`, `3.x` - `react-native-gesture-handler`: `2.x` ## Acknowledgement The idea behind this is from `react-native-reanimated-slider`. Since the mentioned module is written with Reanimated v1 API, and hasn't been updated for a long time, I decided to remake it. ## License [MIT License](https://opensource.org/licenses/MIT)
