    1.0.3 • Public • Published

    react-native-stateful-table-view NPM version Build Status

    A React Native component based on FlatList that provides an option to display different views for each of its states (empty datasource, error, loading).

    Installation

    $ npm install --save @ingenuity-labs/react-native-stateful-table-view

    Usage

    The packages consists of various components that users can utilize to make the most of this package:

    • StatefulTableView
    • StatefulTableViewConstants
    • StatefulTableInfoView
    • StatefulTableErrorView
    • StatefulTableLoadingView

    Using all of these components is the recommended approach, although the last three props can be omitted to allow users to provide their own state views.

    StatefulTableView

    The actual table view component that utilizes a FlatList component in the hood. What makes it different from a regular FlatList is that it also handle several conditions to display different views for each of its state.

    It has several required props needed to be supplied in order for the component to work:

    • data - Refers to the actual dataset to be fed to the FlatList.
    • keyExtractor - Function to define the key to be used for each FlatList item.
    • renderItem - Function to configure component to be used for displaying each row.
    • state - The current state of the component.

    Example of its usage (without any kind of customization):

    <StatefulTableView
      data={['Item 1', 'Item 2']}
      keyExtractor={this.keyExtractor}
      renderItem={this.renderItem}
      state={StatefulTableViewConstants.States.DATA}
    />
    

    These other props will allow users to further customize this component:

    • emptyStateView - Providing a component to this prop will override the default empty state view, thus, displaying the provided component instead for an empty state.
    • errorStateView - Providing a component to this prop will override the default error state view, thus, displaying the provided component instead when resulting to an error state.
    • loadingStateView - Providing a component to this prop will override the default loading state view, thus, displaying the provided component instead when loading of dataset is ongoing.
    • refreshControl - A RefreshControl component which will enable pull-to-refresh functionality when provided.
    • separator - A component which will serve as the separator for each row.

    StatefulTableViewConstants

    Dictionary containing the states that the StatefulTableView will recognize in order to display its corresponding state view.

    States: {
      LOADING: 0,
      DATA: 1,
      ERROR: {
        SERVER: -1,
        INTERNET_CONNECTION: -2
      },
    }
    
    • LOADING - Refers to the state in which the process of fetching the dataset is currently ongoing.
    • DATA - Refers to the state in which the fetching of the dataset has either resulted in an empty dataset or has actual content.
    • ERROR - Further divided into SERVER and INTERNET_CONNECTION. The former can be used when fetching of data from an API or other similar platform results in a error, while the latter is if the fetching of data was disrupted by an internet connection problem.

    StatefulTableInfoView

    One of the 3 state views, the StatefulTableInfoView serves as a generic state view, wherein you can provide any information not necessarily tied in to a specific state. By default, it defaults to an empty state view.

    With its default implementation (not supplying any props) will display a "No data available" text intended as a default value for empty states. Providing values to these following props will allow this component to better cater user needs:

    • headerText (required) - The primary text to be displayed in the view.
    • customStyle - A StyleSheet object to customize the appearance of the headerText, detailText, and container.

    A sample customStyle looks like this:

    let padding = 10;
    let customStyle = {
      container: {
      // Your style here
      },
      detailText: {
      // Your style here
      },
      headerText: {
      // Your style here
      },
    };
    
    • detailText - The supplementing information to be displayed in the view.
    • imageDetails - A dictionary supplying values for Image component's props. Not providing the values for the style prop will use the default styling for the image provided by this package.

    A full implementation of this component looks like this:

    <StatefulTableInfoView
      headerText='No data fetched'
      detailText='Please try again later.'
      imageDetails={{
        source: require('./empty.png'),
        // Optional
        style: {
          // Your style here
        }
      }}
      customStyle={customStyle}
    />
    

    StatefulTableErrorView

    Another of the three state views, the StatefulTableErrorView serves as a state view specific for error states.

    Unlike the previous state view, this has a required prop, state, which defines as to what default message it should display. "No internet connection." text is displayed for the INTERNET_CONNECTION error, and "An error occured." for the SERVER error.

    Providing values to these following props will allow this component to better cater user needs:

    • customStyle - A StyleSheet object to customize the appearance of the headerText, detailText, and container.

    See customStyle in StatefulTableInfoView for a sample guide.

    • detailText - The supplementing information to be displayed in the view.
    • headerText (required) - The primary text to be displayed in the view.
    • imageDetails - A dictionary supplying values for Image component's props. Not providing the style prop will use the default styling for the image provided by this package.
    • errorButtonDetails - A dictionary supplying values for the custom ErrorButton component's props bundled in this package. Providing a value for this prop will enable a button to be displayed in the view, which can be further customized by the user.
    errorButtonDetails={{
      onPress: () => {
        this.setState({
          tableViewState: StatefulTableViewConstants.States.LOADING
        });
        this.fetchJokes();
      },
      // Optional
      title: 'Reload',
      // Optional
      customStyle: {
        title: {
          // Your style here
        },
        view: {
          // Your style here
        }
      }
    }}
    

    For the button to have any functionality, the onPress prop must be provided. This is where you will put the function you want to be executed when the button is pressed.

    title refers to the title of the button, and supplying any value defaults the button to have "Retry" as its title.

    Provide a value to the customStyle prop if you want to further customize the appearance of the button.

    A full implementation of this component looks like this:

    <StatefulTableErrorView
      headerText='Error'
      detailText='Cannot complete request. Please try again later.'
      state={StatefulTableViewConstants.States.ERROR.SERVER}
      imageDetails={{
        source: require('./empty.png'),
        style: {
          // Your style here
        }
      }}
      errorButtonDetails={{
        onPress: () => {
          console.log('Clicked')
        },
        // Optional
        title: 'Reload',
        // Optional
        customStyle: {
          view: {
            // Your style here
          }
        }
      }}
      customStyle={customStyle}
    />
    

    StatefulTableLoadingView

    Lastly, the StatefulTableLoadingView is specifically built for the loading state.

    With its default implementation (not supplying any props) will display a "Loading..." text with a default activity indicator. Providing values to these following props will allow this component to better cater user needs:

    • activityIndicatorDetails - A dictionary supplying values for ActivityIndicator component's props. Not providing the style prop will use the default styling for the activity indicator provided by this package.
    • customStyle - A StyleSheet object to customize the appearance of the headerText, detailText, and container.
    • detailText - The supplementing information to be displayed in the view.
    • hasActivityIndicator - Visibility of the activity indicator. Defaults to true.
    • headerText - The primary text to be displayed in the view.

    A full implementation of this component looks like this:

    <StatefulTableLoadingView
      headerText='Processing...'
      detailText='This may take a while'
      activityIndicatorDetails={{
        // Optional
        color: 'black',
        // Optional
        style: {
          // Your style here
        }
      }}
      customStyle={customStyle}
    />
