React-agenda

react-agenda is an advanced agenda that you can quickly integrate into your app. It's a simple yet effective solution for events management. https://revln9.github.io/react-agenda

Installation

The easiest way to use react-agenda is to install it from NPM

npm install react-agenda --save

This will install the agenda component , along other components like the form to add and edit events and the modal , then add these two lines at the beginning of your CSS file.

@import '~react-agenda/build/styles.css';
@import '~react-datetime/css/react-datetime.css';

Note that the library uses moment and moment locale (for internationalization), react-datetime is also used in the forms to help with time picking. Those will get installed if NPM doesn't detect them into your app.

Usage

this will get you started with the basic requirements.

import React from 'react';
import { ReactAgenda , ReactAgendaCtrl , guid ,  Modal } from 'react-agenda';

require('moment/locale/fr.js'); // this is important for traduction purpose

var colors= {
  'color-1':"rgba(102, 195, 131 , 1)" ,
  "color-2":"rgba(242, 177, 52, 1)" ,
  "color-3":"rgba(235, 85, 59, 1)"
}

var now = new Date();

var items = [
  {
   _id            :guid(),
    name          : 'Meeting , dev staff!',
    startDateTime : new Date(now.getFullYear(), now.getMonth(), now.getDate(), 10, 0),
    endDateTime   : new Date(now.getFullYear(), now.getMonth(), now.getDate(), 12, 0),
    classes       : 'color-1'
  },
  {
   _id            :guid(),
    name          : 'Working lunch , Holly',
