Usage

Initialization example

import React from "react";
import moment from "moment";
import Timetable from "react-native-calendar-timetable";

export default function App() {
    /**
     * By default Timetable renders one column.
     * This sets date for that column, by default equals to new Date().
     * Can be instance of Date or an ISO string.
     * Essentially, a shortcut for range {from: date, till: date}.
     */
    const [date] = React.useState(new Date());

    /**
     * If you would like to have multiple columns (e.g. from Monday to Sunday),
     * you can specify range of dates. Each day of said range will have its own column.
     *
     * 'from' and 'till', just like 'date', can be instances of Date or an ISO strings.
     *
     * It is safe to keep 'from' and 'till' in separate states if you need to
     * because Timetable only check if 'from' or 'till' had changed and
     * not the object that contains them.
     */
    const [from] = React.useState(moment().subtract(3, 'days').toDate());
    const [till] = React.useState(moment().add(3, 'days').toISOString());
    const range = {from, till};

    const [items] = React.useState([
        {
            title: 'Some event',
            startDate: moment().subtract(1, 'hour').toDate(),
            endDate: moment().add(1, 'hour').toDate(),
        },
    ]);

    return (
        <ScrollView>
            <Timetable
                // these two are required
                items={items}
                cardComponent={MyItemCard}

                // provide only one of these if you need to
                date={date} // optional
                range={range} // optional
            />
        </ScrollView>
    );
}

CardComponent example

/**
 * Example item component
 * @param style Object with pre-calculated values, looks like {position: 'absolute', zIndex: 3, width: Number, height: Number, top: Number, left: Number}
 * @param item One of items supplied to Timetable through 'items' property
 * @param dayIndex For multiday items inicates current day index
 * @param daysTotal For multiday items indicates total amount of days
 */
export default function MyItemCard({style, item, dayIndex, daysTotal}) {
    return (
        <View style={{
            ...style, // apply calculated styles, be careful not to override these accidentally (unless you know what you are doing)
            backgroundColor: 'red',
            borderRadius: 10,
            elevation: 5,
        }}>
            <Text>{item.title}</Text>
            <Text>{dayIndex} of {daysTotal}</Text>
        </View>
    );
}

Customization

Styles

All of these keys must be defined on style prop, e.g. style.container.

⚠️ Please be careful while customizing styles as some properties may override those calculated by Timetable, such as width and height of style.headerContainer.
They were not ignored to allow customization in some extreme edge cases.
Refer to Layout segment for layout customization.

Key Style type Description
container View Styles of the main container
headerContainer View Styles of the container of column’s header
headerText Text Styles of the Text of column’s header
headersContainer View Styles of the View that wraps all header containers
contentContainer View Styles of the container of lines and cards
timeContainer View Styles of time containers
time Text Styles of time text
lines View Styles of Views that render lines
nowLine.dot View* Styles of the circle of the ‘current time’ line
nowLine.line View** Styles of the line of the ‘current time’ line

*, ** due to how these Views are used, their customization options were limited:

*: width, height, backgroundColor, borderRadius, zIndex, elevation

**: height, backgroundColor, zIndex, elevation
