How to schedule job in node js?

Question

How can we schedule our job in node.js? Is there any way to achieve this? Is there any way except cron job?

We have a tender model and want to change status after closing date has passed.

Which way would be best?

module.exports = function(sequelize, DataTypes) {
var SpreeOpenTenders = sequelize.define(
  "SpreeOpenTenders",
  {
    tender_name: {
      type: DataTypes.STRING
    },
    created_by: {
      type: DataTypes.STRING
    },
    tender_closing_date: {
      type: DataTypes.DATE
    },
    announcement_date: {
      type: DataTypes.DATE
    },
    expected_delivery_date: {
      type: DataTypes.DATE
    },
    state: {
      type: DataTypes.STRING,
      defaultValue: "Open",
      comment: "Open, On going, Bid selection, Completed"
    }
  }
);

No @MaximSagaydachny, in that function will call every time but we want to run it once when the time has been out. — Pradip Bhuvani, Dec 26 '19 at 09:17
And how will you know that time run out unless you check it? — Maxim Sagaydachny, Dec 26 '19 at 09:20
You can use schedule function in agenda.js . https://github.com/agenda/agenda — Amaranadh Meda, Dec 26 '19 at 09:33
Do not schedule cron through node.js code. I suggest not to accept any tender after the date has been passed. Customize your code on Dates and time bases. — mehta-rohan, Dec 26 '19 at 14:02
Hi @mehta-rohan Can you please give an example how we can achieve this and How status will be updated in database? — Pradip Bhuvani, Jan 16 '20 at 12:51

There are some techniques through which we can derive a value depending on another value in a Schema. But that case is only triggered on data update or creation. So, this method will not be useful in your scenario.

So, according to my knowledge, you cannot avoid cron job. The thing you can do is look for a Node.js cron job scheduler that requires minimal resources to execute. One of the scheduler that i personally use is cron.

Hope this will help you.
