How to Use

Initialize

Add @ridi/react-webviewer reducer into your reducers.

import { reducers as viewerScreen } from '@ridi/react-webviewer';
import { combineReducers } from 'redux';

const appReducer = combineReducers({
    ...
    viewerScreen,
    ...
});

Connect ViewerHelper, PageCalculator, ReadPositionHelper with redux store.

import { createStore } from 'redux';
import { ViewerHelper, PageCalculator, ReadPositionHelper } from '@ridi/react-webviewer';

const store = createStore( ... );
ViewerHelper.connect(store, { ...options });
PageCalculator.connect(store, { ...options });
ReadPositionHelper.connect(store);

ViewerHelper's options = defaults:

• paddingVertical = DEFAULT_PADDING_VERTICAL(35),
• pageMaxWidth = PAGE_MAX_WIDTH(700),
• pageViewerSelector = PAGE_VIEWER_SELECTOR(#viewer_contents .pages),
• extendedTouchWidth = EXTENDED_TOUCH_WIDTH(100),

PageCalculator's options = defaults:

• containExtraPage = 1

ViewerScreen Component

ViewerScreen component provides all functionality of viewer and renders viewer body.

Put ViewerScreen component into your component.

import React from 'react';
import ViewerScreen from '@ridi/react-webviewer';

export default ViewerPage extends React.Component {
    render() {
        return <ViewerScreen />;
    }
};

ViewerScreen's properties:

• onMount(func): called after viewer is mounted
• onUnmount(func): called after viewer is unmounted
• onMoveWrongDirection(func): called when user try to tap wrong direction to the next page (on page viewerType)
• footer(node): markup for the footer area
• fontDomain(string): prefixed URL for searching font files
• ignoreScroll(bool): temporarily disable scrolling (on scroll viewerType)
• disablePageCalculation(bool): temporarily disable page calculation (on page viewerType)

You can extend or replace child components of ViewerScreen with the HoC-style function createStyledViewerScreen().

// Signature
createStyledViewerScreen = ({
  TouchableScrollScreen = ScrollScreen,
  StyledScrollContents = ScrollContents,
  TouchablePageScreen = PageScreen,
  StyledPageContents = PageContents,
  SizingWrapper = SizingWrapper,
} = {}) => ViewerScreen

This is an example.

import {
    createStyledViewerScreen,
    SizingWrapper,
    ScrollContents,
    PageContents,
    ScrollScreen,
    PageScreen,
} from '@ridi/react-webviewer';

const TouchableScrollScreen = ScrollScreen.extend`...`;
const TouchablePageScreen = PageScreen.extend`...`;
...

createStyledViewerScreen({
    TouchablePageScreen,
    TouchableScrollScreen,
    ...,
})

Render Contents

• Update meta data with updateMetaData
• Render contents with renderSpine or renderImages

updateMetaData

Dispatch updateMetaData action to update content's metadata.

import {
  updateMetaData,
  ContentType,
  AvailableViewerType,
  BindingType,
} from '@ridi/react-webviewer';

const contentType = ContentType.COMIC;
const viewerType = AvailableViewerType.BOTH;
const bindingType = BindingType.LEFT;

dispatch(updateMetaData(contentType, viewerType, bindingType));

• viewerType: available viewer type (BOTH: 0, SCROLL: 1, PAGE: 2)
• contentType: content type (WEB_NOVEL: 10, COMIC: 20, WEBTOON: 30)
• bindingType: binding type (LEFT: 0, RIGHT: 1)

renderSpine

And then dispatch renderSpine action to render html into the viewer after loading contents data.

import { renderSpine } from '@ridi/react-webviewer';

...
const index = 0;
const html = '<h1>hello, world</h1>';
dispatch(renderSpine(index, html));

renderImages

If you have image contents to render lazily, dispatch renderImages instead of renderSpine.

import { renderImages } from '@ridi/react-webviewer';

...
const images = [{ src: '/image_1.jpg' }, { src: '/image_2.jpg' }, ...];
dispatch(renderImages(images));
