React Calendar Component
You can add the React calendar component to your JSX using <DayPilotCalendar> tag:
import React, {Component} from 'react';
import {DayPilot, DayPilotCalendar} from "daypilot-pro-react";
class Calendar extends Component {
render() {
return (
<div>
<DayPilotCalendar />
</div>
);
}
}
export default Calendar;The DayPilotCalendar React component is available as part of DayPilot Pro JavaScript, React package (daypilot-pro-react). This package is hosted at npm.daypilot.org.
You can add it to your React application using npm or yarn.
NPM
npm install https://npm.daypilot.org/daypilot-pro-react/trial/2019.3.4012.tar.gz --save
Yarn
yarn add https://npm.daypilot.org/daypilot-pro-react/trial/2019.3.4012.tar.gz
Weekly Calendar
By default, the calendar displays one day (day view). There are several modes available:
- Day
- Week
- WorkWeek
- Days (custom number of days)
- Resources (custom columns)
We will switch the calendar to the week view using viewType property:
import React, {Component} from 'react';
import {DayPilot, DayPilotCalendar} from "daypilot-pro-react";
class Calendar extends Component {
constructor(props) {
super(props);
this.state = {
viewType: "Week"
};
}
render() {
var {...config} = this.state;
return (
<div>
<DayPilotCalendar
{...config}
/>
</div>
);
}
}
export default Calendar;React Calendar: Appearance Customization
We will make a couple of changes to the calendar appearance.
By default, the calendar events display a duration bar at the left side. It indicates the real event duration in case that in doesn't match the grid cells exactly.
In our React application, we will turn the duration bar off using durationBarVisible property:
import React, {Component} from 'react';
import {DayPilot, DayPilotCalendar, DayPilotNavigator} from "daypilot-pro-react";
import "./CalendarStyles.css";
class Calendar extends Component {
constructor(props) {
super(props);
this.state = {
// ...
durationBarVisible: false,
// ...
};
}
render() {
var {...config} = this.state;
return (
<div>
<DayPilotCalendar
{...config}
/>
</div>
);
}
}
export default Calendar;
As the next step, we will customize the appearance of the calendar events using CSS.
The calendar styles are set by a CSS theme. The calendar component includes a built-in theme which defines the default appearance ("calendar_default").
You can create your own theme using the online theme designer or you can simply override selected styles of the built-in theme. That's what we are going to do in this example:
CalendarStyles.css
/* adjusting the built-in theme */
/* calendar event */
.calendar_default_event_inner {
background: #2e78d6;
color: #fff;
border: none;
font-size: 10pt;
padding: 5px;
opacity: 0.8;
}
This CSS overrides the default calendar event appearance - it will use white text on light blue background:
Date Picker: Navigator Component
In order to let users change the visible week, we will use a date picker component called Navigator. You can add the navigator to the React JSX page using <DayPilotNavigator> tag:
render() {
return (
<div>
<DayPilotNavigator />
// ...
</div>
);
}The navigator fires onTimeRangeSelected event whenever a user clicks a date:
render() {
return (
<div>
<DayPilotNavigator
onTimeRangeSelected={ args => {
console.log("You clicked: " + args.day);
}}
/>
// ...
</div>
);
}We will use this event to change the startDate property of the state object. React will detect the change and the calendar component will be updated automatically.
import React, {Component} from 'react';
import {DayPilot, DayPilotCalendar, DayPilotNavigator} from "daypilot-pro-react";
import "./CalendarStyles.css";
const styles = {
left: {
float: "left",
width: "220px"
},
main: {
marginLeft: "220px"
}
};
class Calendar extends Component {
constructor(props) {
super(props);
this.state = {
viewType: "Week",
durationBarVisible: false
};
}
render() {
var {...config} = this.state;
return (
<div>
<div style={styles.left}>
<DayPilotNavigator
selectMode={"week"}
showMonths={3}
skipMonths={3}
onTimeRangeSelected={ args => {
this.setState({
startDate: args.day
});
}}
/>
</div>
<div style={styles.main}>
<DayPilotCalendar
{...config}
ref={component => {
this.calendar = component && component.control;
}}
/>
</div>
</div>
);
}
}
export default Calendar;
React Calendar: Loading Events
The calendar event data can be loaded by setting events property of the state object:
componentDidMount() {
// load event data
this.setState({
startDate: "2019-09-15",
events: [
{
id: 1,
text: "Event 1",
start: "2019-09-16T10:30:00",
end: "2019-09-16T13:00:00"
},
{
id: 2,
text: "Event 2",
start: "2019-09-17T12:00:00",
end: "2019-09-17T14:00:00",
backColor: "#38761d"
}
]
});
}
