react-native-spinner-button

This is a pure javascript and react-native Button component with a Spinner embeded in it. In many of the react-native projects we have worked on required the button to be disabled when app is processing something on tap of that button, and a loading indicator on it or beside it, so the user can be made aware of app doing some processing.

From a developer perspective, it is very painful to manage two different components: a button and a spinner for lots of buttons! So when we came accross this beautiful component SSspinnerButton, we decided to do something like that in react-native.

By default it will render a Button and you have to pass a boolean isLoading prop to it. When the isLoading will be true, it will render a Spinner in place of the Button and once its false, the Button will be rendered back again.

Features

• Drop in replacement for a button and indicator combo
• Very easy to use
• Pure javscript component
• Consistent look and feel on both iOS and Android
• Any spinner from react-native-indicators can be used with most of its properties
• The animations fadeIn, flipInX and flipInY can be used from react-native-animatable
• Give any style to your button

Getting Started

npm i react-native-spinner-button --save

Usage

import SpinnerButton from 'react-native-spinner-button';
...
// Your button component
  <SpinnerButton
    buttonStyle={styles.buttonStyle}
    isLoading={this.state.defaultLoading}
    onPress={() => {
      this.setState({ defaultLoading: true });
    }}
    indicatorCount={10}
  >
    <Text style={styles.buttonText}>Default Or Ball SpinnerButton</Text>
  </SpinnerButton>

Don't forget to set the state variable you have given to isLoading prop false when processing is done for the button tap.

Common properties

1. animationType
   • Type of animation for the button and spinner.
   • Default type: string
   • Default value: null | undefined
2. buttonStyle
   • Its a stylesheet object.
   • Default button style

       defaultButtonStyle: {

3. borderStyle
   • Its a stylesheet object with support all basic border property like width, radius, color and style(solid, dotted and dashed) etc.
   • If you want to need to apply border in your button then you should used like

       buttonBorderStyle: {
         borderWidth: 2,

       }
     

4. spinnerColor
   • The color of the Spinner.
   • Default type: string
   • Its default value is white. You can give spinnerColor in all react-native acceptable formats of color.
5. spinnerType
   • Type of the spinner.
   • Default type: string
   • Its default value is BallIndicator.
   • These are all spinner types:
     1. BallIndicator
     2. BarIndicator
     3. DotIndicator
     4. MaterialIndicator
     5. PacmanIndicator
     6. PulseIndicator
     7. SkypeIndicator
     8. UIActivityIndicator
     9. WaveIndicator
6. isLoading
   • The flag to render a Button or a Spinner. false will render button and true will render spinner.
   • Default type: boolean
   • Default value: false
7. onPress
   • The function to execute on tap of the button.
   • Default type: function.
   • Default value: nothing is executed
8. indicatorCount
   • The count property of react-native-indicators.
   • Default type: number
   • Default value: null | undefined
9. size
   • The size of the Spinner.
   • Default type: number
   • Its default value veries according to the spinnerType.
10. spinnerOptions
    • An object of waveMode for WaveIndicator for WaveIndicator.
    • Default type: Object
    • For more details about these properties, refer react-native-indicators
11. gradientType
    • Gradients allow you to show more than one color with a smooth transition between the colors (think Instagram logo).
    • They come in handy when trying to create multi-color backgrounds or custom buttons. You can have gradients in different varieties, horizontally, vertically, diagonally, etc.
    • Currently, we are supporting two types of gradient 1.Linear Gradient & 2.Radial Gradient.
12. gradientColors
    • This is how we pass the colors we want to be displayed, colors can be passed in a different format, name, rgba, hex etc.
    • The colors should be ordered the way we want them to be displayed.
    • Eg. colors={[ “purple”, “white” ]} the gradient will move from purple to white.
13. gradientColoroffset
    • An array of string that define where each color will stop in the gradient.
    • These values are also passed as a percentage of the entire gradient from 0% – 100% and have to map the corresponding colors passed in length and position.
    • For colors={[“red”, “yellow”, “green”}] then we’ll have locations={['0%', '50%', '80%']} with first color (red) covering '0%' – '50%', second (yellow) going from '50%' – '80%' and yellow '80%' – '100%'
14. gradientColorAngle
    • The gradient line's angle of direction. A value of 0deg is equivalent to to top; increasing values rotate clockwise from there.
    • The angle range of 0 to 360.
    • More detail to read
15. gradientRadialRadius
    • This property used for Radial type gradient in set radius of radial gradient.
16. gradientButtonHeight
    • The size of the gradient component.
    • Default type: number
17. radialRadiusx
    • The x coordinate of the center of the radial gradient.
18. radialRadiusy
    • The y coordinate of the center of the radial gradient.
19. radialRadiusRX
    • The horizontal radius of the radial gradient defining ellipse.
20. radialRadiusRY
    • The vertical radius of the radial gradient defining ellipse.
21. animatedDuration
    • Used for animation time, how long you have to execute your animation.
22. customSpinnerComponent
    • This props will allow you to add your own custom spinner component.
23. animateWidth
    • This props used to set component width when progress/loading will start..
    • If you want to not set this props then identify width and height which is minimum and then used that value.
24. animateHeight
    • This props used to set component height when progress/loading will start.
    • If you want to not set this props then identify width and height which is minimum and then used that value.
25. animateRadius
    • This props used to set component radius when progress/loading will start.
    • If you want to not set this props then create circle shape.
26. isConnected
    • The flag to identify network connection and based on flag set user iteration. false will render button with disable mode and true will render button with normal mode.
    • Default type: boolean
    • Default value: true
27. isDisable
    • The flag to identify button enable/disable. true will render button with disable mode and false will render button with normal mode.
    • Default type: boolean

28. disableStyle
    • Its a stylesheet object.
    • This style apply when identify button disable or if network connect not available.

29. gradientName
    • Its a sample gradient name.
    • Default type: string
    • Its default value is null | undefined.
    • This properties used whenever you want to need gradient but not pass gradientColors, gradientColoroffset and gradientColorAngle properties.
    • if you want to see color combination of Sample gradient
