Optimize Toolset

I’ve always been into building performant and accessible sites, but lately I’ve been taking it extremely seriously. So much so that I’ve been building a tool to help me optimize and monitor the sites that I build to make sure that I’m making an attempt to offer the best experience to those who visit them. If you’re into performant, accessible and SEO friendly sites, you might like it too! You can check it out at Optimize Toolset.

About

Hi, 👋, I’m Ryan Hefner  and I built this site for me, and you! The goal of this site was to provide an easy way for me to check the stats on my npm packages, both for prioritizing issues and updates, and to give me a little kick in the pants to keep up on stuff.

As I was building it, I realized that I was actually using the tool to build the tool, and figured I might as well put this out there and hopefully others will find it to be a fast and useful way to search and browse npm packages as I have.

If you’re interested in other things I’m working on, follow me on Twitter or check out the open source projects I’ve been publishing on GitHub.

I am also working on a Twitter bot for this site to tweet the most popular, newest, random packages from npm. Please follow that account now and it will start sending out packages soon–ish.

Open Software & Tools

This site wouldn’t be possible without the immense generosity and tireless efforts from the people who make contributions to the world and share their work via open source initiatives. Thank you 🙏

Installation & Usage

To install this module cd to your project directory and enter the following command:

yarn add @react-native-community/slider

or

npm install @react-native-community/slider --save

If using iOS please remember to install cocoapods by running: npx pod-install

The following code presents the basic usage scenario of this library:

import Slider from '@react-native-community/slider';

<Slider
  style={{width: 200, height: 40}}
  minimumValue={0}
  maximumValue={1}
  minimumTrackTintColor="#FFFFFF"
  maximumTrackTintColor="#000000"
/>

Check out the example project for more examples.


Migrating from the core react-native module

This module was created when the Slider was split out from the core of React Native. To migrate to this module you need to follow the installation instructions above and then change you imports from:

import { Slider } from 'react-native';

to:

import Slider from '@react-native-community/slider';

React Native Compatibility

To use this library you need to ensure you are using the correct version of React Native.

| @react-native-community/slider version | Required React Native Version | | ---------------------------------------- | ----------------------------- | | 4.x.x | >=0.60; >=0.62 (on Windows); | | 3.1.x | >=0.60 | | 2.x.x | >= 0.60 | | 1.x.x | <= 0.59 |

The user won't be able to slide below this limit. | number | No | Android, iOS | | upperLimit | Slide upper limit. The user won't be able to slide above this limit. | number | No | Android, iOS | | onSlidingStart | Callback that is called when the user picks up the slider.The initial value is passed as an argument to the callback handler. | function | No | | | onSlidingComplete | Callback that is called when the user releases the slider, regardless if the value has changed.The current value is passed as an argument to the callback handler. | function | No | | | onValueChange | Callback continuously called while the user is dragging the slider. | function | No | | | step | Step value of the slider. The value should be between 0 and (maximumValue - minimumValue). Default value is 0.On Windows OS the default value is 1% of slider's range (from minimumValue to maximumValue). | number | No | | | maximumTrackTintColor | The color used for the track to the right of the button.Overrides the default gray gradient image on iOS. | color | No | | | testID | Used to locate this view in UI automation tests. | string | No | | | value | Write-only property representing the value of the slider.

Default value is 0.This is not a controlled component, you don't need to update the value during dragging. | number | No | | | tapToSeek | Permits tapping on the slider track to set the thumb position.Defaults to false on iOS.

Roadmap and Progress

There's a Project board available here which contains all reported issues organized into columns regarding their status.

If you are interested in knowing whether the issue you reported is handled or just to check the status of a feature you would like to have in Slider, please check the board.

Contributing

The main package implementation is done in the package/ directory. So when implementing changes there, make sure your code passes ESLint and the tests. Run the following to verify:

cd package/
npm run lint
npm run test
  • Remember to cover your changes with tests if possible.

When creating an issue please remember to specify the platform which the issue occurs on.

Running the example app

While developing, you can run the example app to test your changes.

Setup

  • Clone the repository
  • Run npm install in the root directory to install dependencies.
  • Run npm run example-<platform>, where platform can be: ios, android, windows

You can also do this manually by:

  • Installing node modules for example app
  • Installing pods for iOS app
  • Running example app like always: npx react-native run-<platform>

New architecture setup (Fabric)

In order to use the new architecture some extra steps are needed.

iOS

  • Install pods with new arch flag inside example/ios folder: RCT_NEW_ARCH_ENABLED=1 pod install
  • Run npm run example-ios

Android

  • Set newArchEnabled to true inside example/android/gradle.properties
  • Run npm run example-android

Inside example/android/app/src/main/jni/Android.mk add these lines:

+ include $(NODE_MODULES_DIR)/@react-native-community/slider/android/build/generated/source/codegen/jni/Android.mk
include $(CLEAR_VARS)
    libreact_codegen_rncore \
+   libreact_codegen_ReactSlider \
    libreact_debug \

Inside example/android/app/src/main/jni/MainComponentsRegistry.cpp update these lines:

#include <react/renderer/components/rncore/ComponentDescriptors.h>
+ #include <react/renderer/components/ReactSlider/ComponentDescriptors.h>

...

MainComponentsRegistry::sharedProviderRegistry() {
  auto providerRegistry = CoreComponentsRegistry::sharedProviderRegistry();

  // Custom Fabric Components go here. You can register custom
  // components coming from your App or from 3rd party libraries here.
  //
  // providerRegistry->add(concreteComponentDescriptorProvider<
  //        AocViewerComponentDescriptor>());
+ providerRegistry->add(concreteComponentDescriptorProvider<RNCSliderComponentDescriptor>());

  return providerRegistry;
}
