Transform the event information based on specific configuration settings

Question

Transform the event information based on specific configuration settings

I possess an array containing JSON data named config.

var config =  [ [{'state': 'step1'}],
                [{'state': 'step2'}] , 
                [{'state': 'step3'}]
              ];

The data in config is orderly arranged.

Additionally, I hold JSON data named Events, which includes these states but they are not sequential. I aim to modify the Events data based on the config.

Events: [ 
           { Status: 'rendered',  State: 'step2' },
           { Status: 'rendered',  State: 'step3' },
           { Status: 'rendered',  State: 'step1' } ,
           { Status: 'completed', State: 'step3'}  
       ],

Moreover, the final step of the config will have two entries and in that case, the rendered state should precede the completed state.

The expected outcome is as follows:

Events: [ 
            { Status: 'rendered',  State: 'step1' },
            { Status: 'rendered',  State: 'step2' },
            { Status: 'rendered',  State: 'step3' } ,
            { Status: 'completed', State: 'step3' }  
        ]

Note: I do not currently have any functional or error-prone code for this task. Essentially, I am struggling to figure out how to utilize the config to modify the Events.

Thank you

Answer №1

Reformat the config variable into a string array, and then utilize the .sort function while comparing the difference in the indexOf values of the States property within that array:

var config =  [ [{'state': 'step1'}],
        [{'state': 'step2'}] , 
        [{'state': 'step3'}]
      ];
const Events = [ 
   { Status: 'rendered',  State: 'step2' },
   { Status: 'rendered',  State: 'step3' },
   { Status: 'rendered',  State: 'step1' } ,
   { Status: 'completed', State: 'step3'}  
];

const eventOrders = config.map(([{ state }]) => state);
Events.sort((a, b) => (
  eventOrders.indexOf(a.State) - eventOrders.indexOf(b.State)
  || Events.indexOf(a) - Events.indexOf(b)
));
console.log(Events);

If you want to achieve this, here are the steps you need to follow:

Start by converting the array from the configuration, which looks like ['step1','step2','step3']
Proceed to use the sort() function on the events array
Next, sort the objects in the events array based on the indexOf() method of the State property of items in the array above

var config =  [ [{'state': 'step1'}],
                [{'state': 'step2'}] , 
                [{'state': 'step3'}]
              ];

let states = config.map(x => x[0].state);
const events = [ 
           { Status: 'rendered',  State: 'step2' },
           { Status: 'rendered',  State: 'step3' },
           { Status: 'rendered',  State: 'step1' } ,
           { Status: 'completed', State: 'step3'}  
       ]
 const res = events.sort((a,b) => states.indexOf(a.State) - states.indexOf(b.State));
 console.log(res);

Answer №3

Implemented a new logic to ensure that the status of 'rendered' comes before 'completed' if the states are the same.

var config =  [ 
    [{'state': 'step1'}],
    [{'state': 'step2'}], 
    [{'state': 'step3'}]
];

const Events = [ 
    { Status: 'rendered',  State: 'step2' },
    { Status: 'completed',  State: 'step3' },
    { Status: 'rendered',  State: 'step1' } ,
    { Status: 'rendered', State: 'step3'}  
];

const eventOrders = config.map( ([{state}]) => state);

Events.sort((a, b) => {    
    let result = eventOrders.indexOf(a.State) - eventOrders.indexOf(b.State);
    if(result == 0){
        if(a.Status=='rendered' && b.Status=='completed') return -1;
        if(b.Status=='rendered' && a.Status=='completed') return 1;
        return 0;
    }
    return result;
});

console.log(Events);

I've found a solution that may work for you too.

function reorganizeArray(arrToReorganize, arrToMatch, keyOfMainArray, keyOfMatchingArray) {
let reorganizedArr = [];
arrToMatch.map((val) => {
    let res = arrToReorganize.filter(obj => { return obj[keyOfMainArray] == val[0][keyOfMatchingArray] });
    res.map(r => reorganizedArr.push(r))
});
 return reorganizedArr;
}

function moveObjectToEnd(arr, key, val) {
  let lastObj = {};
  arr = arr.filter((obj) => {
    if (obj[key] == val) {
        lastObj = obj;
    }
    return obj[key] != val
 });
 arr.push(lastObj);
 return arr;
}

 let newArrangement = reorganizeArray(Events, config, 'State', 'state');
 newArrangement = moveObjectToEnd(newArrangement, 'Status', 'completed');
