React Google Calendar

A react component that displays an event calendar using data from google's calendar api. It is intended to replace the embedded google calendar.

It handles reccuring events, deleted events, and changed events. It also handles and displays events of all lengths in a very similar way to google calendar and supports multiple calendars. All events are displayed in the user's timezone.

Design inspired by this calendar and Google Calendar. Icons from Material Design.

Installation

1. npm install --save react react-dom @emotion/react
2. npm install --save @ericz1803/react-google-calendar

Usage

First, get an api key from here by following step 1.

Alternately, you can go to https://console.developers.google.com/flows/enableapi?apiid=calendar.

Then, get the calendar id from the google calendar. It will look something like 09opmkrjova8h5k5k46fedmo88@group.calendar.google.com.
You can find it by going to a calendar's settings and scrolling down to the section that is labelled Integrate calendar.

Basic Example

import React from "react";
import Calendar from "@ericz1803/react-google-calendar";

const API_KEY = "YOUR_API_KEY";
let calendars = [
  {calendarId: "YOUR_CALENDAR_ID"},
  {
    calendarId: "YOUR_CALENDAR_ID_2",
    color: "#B241D1" //optional, specify color of calendar 2 events
  }
];

class Example extends React.Component {
  render() {
    return (
      <div>
        <Calendar apiKey={API_KEY} calendars={calendars} />
      </div>
    )
  }
}

Properties

Parameter Type Description
apiKey string google api key (required)
calendars array of objects google calendar id and display color (required)
styles object styles (optional, see more below)
showArrow boolean shows arrow for events that span multiple months (optional, defaults to true)

Customization

You can customize the color of each calendar's events by specifying a color field with the calendar id (see examples).

To customize other aspects of the calendar (eg. borders, colors of the calendar), pass in a styles object. Each of the styles in the styles object should be an object style (the same as react inline styles) or an emotion css string style (see more here). If you choose to use emotion's css string styles, make sure to import { css } from "@emotion/react".

Style Keys

  • calendar
  • day
  • today
  • tooltip
  • event
  • eventText
  • eventCircle
  • multiEvent

Example With Customization

import React from "react";
import Calendar from "@ericz1803/react-google-calendar";
import { css } from "@emotion/react";

const API_KEY = "YOUR_API_KEY";
let calendars = [
  {calendarId: "09opmkrjova8h5k5k46fedmo88@group.calendar.google.com", color: "#B241D1"}, //add a color field to specify the color of a calendar
  {calendarId: "hkr1dj9k6v6pa79gvpv03eapeg@group.calendar.google.com"}, //without a specified color, it defaults to blue (#4786ff)
  {calendarId: "rg4m0k607609r2jmdr97sjvjus@group.calendar.google.com", color: "rgb(63, 191, 63)"} //accepts hex and rgb strings (doesn't work with color names)
];

let styles = {
  //you can use object styles (no import required)
  calendar: {
    borderWidth: "3px", //make outer edge of calendar thicker
  },
  
  //you can also use emotion's string styles
  today: css`
   /* highlight today by making the text red and giving it a red border */
    color: red;
    border: 1px solid red;
  `
}
