The combination of Node. In this tutorial, we will explain how dhtmlxScheduleran embeddable JavaScript calendar, can be used to create an online event calendar with Node.

You can download the full archive with the final solution from GitHub. One of the advantages of Node. You can find a complete demo of using dhtmlxScheduler and Node. Then we create the base of our application — app.

Due to the use of the Express framework, the whole app fitted into several lines. After that, the whole file structure will look like this:. Now, we create index. It will be the main page where we will place our calendar. Here is the content of this file:. To check how the app works, we may start the Node.

If everything is done correctly, we will see a calendar without events to start Node. It just adds a few records into the database. Here we choose all the records from the database and send them to the client side as JSON structure. NOTE: Before sending the records, we define the id property for each object. We have added two lines. The first one defines how to parse dates from the incoming data.

Most often, while loading data from the server, dates are stored like strings in a special format. In our case, dates are stored as timestamps and we can convert them into date objects through Date constructor.

The second line initiates data loading, using the URL described above. To add the ability to add, edit, and delete events in the calendar, we need to add the code that initializes dataprocessor to the index.

The first line defines the format the dates will take while going back to the server. We are using default year-month-day order that can be parsed by MongoDB. The following block initializes dataprocessor and switches it to the mode of simple POST sending. Here we use app. The first part of the code defines the type of operation and removes all the technical parameters from an incoming query to get an object that can be saved in the database.

Next, depending on the type of operation, we call the related method of db.The current tutorial is intended for creating Scheduler with Node. If you use some other technology, check the list of available integration variants below:. Our implementation of Scheduler with Node.

The complete source code is available on GitHub. You should setup your MySQL server, or use some service, e.

Now you should create this file with the code below:. Scheduler will use the size of its container, so some initial sizes are required. After you have added a new page, you need to make it accessible from a browser. For this tutorial, scheduler will be the default page of an app. So, you've got an empty scheduler.

Let's connect it to the database and define methods to read and write events to it. First things first, we need a database to work with. You can create a database with your favorite mysql-client, or via the console. To import with a mysql-console, create a dump.

And execute command in the shell:. Let's define MySQL connection settings in a constant in server. They will be used later in the storage. Here connection pooling is used and queries are wrapped into Promises. It's not strictly necessary for our app to work, but it will definitely look good later on. At the next step all the database access will be put into a separate class called Storage.

It'll handle database connection and all CRUD actions. It'll take mysql connection and perform simple CRUD to the specified table: read all the events, insert new events, update or delete the existing ones. Then you need to set up routes, so the storage could be accessed by the scheduler you have placed on the page. All it does is sets up the application to listen request URLs that scheduler can send and calls the appropriate methods of the storage.

Note, that all methods are wrapped into try-catch blocks, for you to be able to capture any error and return an appropriate error response to the client. Check more info on error handling. Also note that the exception message is written directly to the API response. It's pretty handy during the development, but in the production environment it can be a good idea to hide these messages from the client side, since raw mysql exceptions that get there may contain sensitive data.

If you restart the application now, you should be able to create delete and modify events in scheduler, all changes will be there after you reload the page. Currently scheduler loads all records from the events table on startup.

It can work well if you know that the amount of data will remain small over time. It can easily be avoided by using dynamic loading. Scheduler will add the displayed dates to the request parameters and you'll be able to return only the records that need to be displayed.

Each time the user switches to a new data range, scheduler will request a new portion of data. To enable dynamic loading in UI, you can set the setLoadMode option to any of the values: "day", "week", "month". For any practical reasons, "day" should work well. Firstly, enable dynamic loading on the client using the setLoadMode method:. Scheduler will sent from and to parameters in the request query, so you can add a simple WHERE clause in order to load only the requested range:.

In order to enable recurring events e.The easiest way to schedule work items with complex dependencies across developers that all have different work schedules.

Alright, so we're not supposed to view the resource unauthenticated and we need to supply an authorization token.

How can we get a token? Perhaps follow one of the links? At this point there are two options:. With postMessage it's possible to send values between browser windows and different domains. This generates our authorization token:. If things went alright, we now have the authorization token. Looking good! Where can we go next?

Node Schedule is a flexible cron-like and not-cron-like job scheduler for Node. It allows you to schedule jobs arbitrary functions for execution at specific dates, with optional recurrence rules. You can install using npm. Node Schedule is for time-based scheduling, not interval-based scheduling.

While you can easily bend it to your will, if you only want to do something like "run this function every 5 minutes", you'll find setInterval much easier to use, and far more appropriate. But if you want to, say, "run this function at the and of every hour on the third Tuesday of every month," you'll find that Node Schedule suits your needs better.

Additionally, Node Schedule has Windows support unlike true cron since the node runtime is now fully supported. Note that Node Schedule is designed for in-process scheduling, i.

If you need to schedule jobs that will persist even when your script isn't running, consider using actual cron. Every scheduled job in Node Schedule is represented by a Job object. You can create jobs manually, then execute the schedule method to apply a schedule, or use the convenience function scheduleJob as demonstrated below. Job objects are EventEmitter 's, and emit a run event after each execution. They also emit a scheduled event each time they're scheduled to run, and a canceled event when an invocation is canceled before it's executed both events receive a JavaScript date object as a parameter.

Note that jobs are scheduled the first time immediately, so if you create a job using the scheduleJob convenience method, you'll miss the first scheduled event, but you can query the invocation manually see below.

Also note that canceled is the single-L American spelling. This is useful when you need to check if there is a delay of the job invocation when the system is busy, or save a record of all invocations of a job for audit purpose. Most other features supported by popular cron implementations should work just fine.

Say you very specifically want a function to execute at am on December 21, Remember - in JavaScript - 0 - January, 11 - December. This will log 'Tada! You can build recurrence rules to specify when a job should recur.
