How To Use?

Update priority using object as input

Lets take an example where top 5 brands car into the competition,
on every hits on the car by viewer it increase the views of the car and at the end of every day we finalized the top priority car and we rate it as a top most priority car brand.

So here, we have set of brands data with their old priority
/* INPUT */
let data = [
  {'id': 1, 'brand': 'Mercedes-Benz', 'priority': 1}, 
  {'id': 2, 'brand': 'BMW', 'priority': 2}, 
  {'id': 3, 'brand': 'Audi', 'priority': 3}, 
  {'id': 4, 'brand': 'Porsche', 'priority': 4}, 
  {'id': 5, 'brand': 'Volkswagen', 'priority': 5}
]
Below is the input data where the dataKey is key which needs to set the new priority which is in dataValue
and rest data objects need to update accordingly.
searchKey is key which helps to identify which objects value is going to update.

let input = {
  dataKey: 'priority',
  dataValue: 1,
  searchKey: 'brand',
  searchValue: 'Porsche'
}

// Method call 
const priority = require('priority-update').priority
let output = priority(data, input)
console.log('OUTPUT -- ', JSON.stringify(output))

/* OUTPUT */
[{"id":4,"brand":"Porsche","priority":1},
{"id":1,"brand":"Mercedes-Benz","priority":2},
{"id":2,"brand":"BMW","priority":3},
{"id":3,"brand":"Audi","priority":4},
{"id":5,"brand":"ravi5","Volkswagen":5,"priority":5}]

Update priority using array of object as input

Continue with the same example

/* INPUT */
let input = [{
      dataKey: 'priority',
      dataValue: 2,
      searchKey: 'brand',
      searchValue: 'Porsche'
    },{
      dataKey: 'priority',
      dataValue: 3,
      searchKey: 'brand',
      searchValue: 'Volkswagen'
    },{
      dataKey: 'priority',
      dataValue: 1,
      searchKey: 'brand',
      searchValue: 'BMW'
    }]

// Method Call
const priorityInBulk = require('priority-update').priorityInBulk
let output = priorityInBulk(data, input)
console.log('OUTPUT -- ', JSON.stringify(output))

/* OUTPUT */
[{"id":2,"brand":"BMW","priority":1},
{"id":4,"brand":"Porsche","priority":2},
{"id":5,"brand":"Volkswagen","priority":3},
{"id":1,"brand":"Mercedes-Benz","priority":4},
{"id":3,"brand":"Audi","priority":5}]
