how can i update the data dynamically after some time using nodejs?

suppose the response is coming from the server when i hit the GET request as:

API response

[
{
  id: 1
  status: "Pending",
  startedAt: "10:30",
  endsAt: "12:30"
},
 {
  id: 2
  status: "Pending",
  startedAt: "11:30",
  endsAt: "1:30"
 },
....
]

now i want to change this status field after every 1 hour to Started and then Finished

how can i do this using node.js and what should be the correct implementation for doing this.

You can simply use setInterval for performing the operation after a specific interval.

var yourData = [
  {
    id: 1
    status: "Pending",
    startedAt: "10:30",
    endsAt: "12:30"
  },
   {
    id: 2
    status: "Pending",
    startedAt: "11:30",
    endsAt: "1:30"
   },
  ....
  ]
async function updateData(){
  //Call your API and update the data
  yourData = await yourAPICall()
}

setInterval(updateData, 60 * 60 * 1000)

You can use the cron job .

Step 1) npm i crontab --save
Step 2) npm i node-cron --save

Now in your index.js or inide your main js file of node . Wirte the following command . 

const cron = require('node-cron');
const crontab = require('node-crontab');

crontab.scheduleJob("0 * * * * " , function(){
     //do something cool    
},{
    schedule: true,
    timezone: "Asia/kolkata"
});

The above function will run at every 1 hour and you can do your code inside that .
