How to delete data from a Firebase database on a schedule

I have created a simple chatroom-like Apache Cordova (HTML) application that allows users to add their own messages with custom usernames in the chatroom.

The messages add up after a while and i have to go into the actual database to delete them every day to avoid clutter.

Is there any way i can create a rule or a javascript function to clear the data at a certain time every day? For instance at 9 am the database would clear all its content from the previous day and night and start the day fresh.

Thanks for the help.

From the looks of it there are two current similar solutions: Creating Scheduled Task in JavaScript || Later.js execute Function on Schedule?

I am unfamiliar with later.js so I can't help you there.

Using gdoron's code, I believe the code should look similar to this:

function foo(){
    var day =new Date().getDay();
    var hours =new Date().getHours();

    if (day === 0 && hours >12 && hours < 13)  // day is a 0 index base
                                               // sunday between 12:00 and 13:00

//What you want to do goes here
var fredRef = new Firebase('yourDirectoryUrl')
fredRef.remove();

}

setInterval(foo, 3600000); // one hour check.

Notes:

  • Remember to include 

    <script src='https://cdn.firebase.com/js/client/2.2.1/firebase.js'></script>

  • Also, keep in mind this will clear EVERYTHING.
