75lb / sort-array Goto Github PK

Low priority but would be nice to have some input validation which ensures the config supplied is valid. E.g. ensure a customOrder is either a function or array of values. The following is invalid and should raise an "invalid config" exception:

sortArray(arr, {
  by: 'something',
  order: 'broken',
  customOrders: {
    broken: new Date()
  }
})

So I have a JSON in the format

{"homepage_card.title":{"type":"StructuredText","value":[{"type":"heading1","text":"Test Card","spans":[]}]},"homepage_card.type":{"type":"Select","value":"default"},"homepage_card.sequence":{"type":"Number","value":4},"homepage_card.description":{"type":"StructuredText","value":[{"type":"paragraph","text":"This is some description","spans":[]}]},"homepage_card.background_image":{"type":"Image","value":{"main":{"dimensions":{"width":960,"height":800},"alt":null,"copyright":null,"url":"https://wroomdev.s3.amazonaws.com/tutoblanktemplate%2F97109f41-140e-4dc9-a2c8-96fb10f14051_star.gif"},"views":{}}},"homepage_card.label":{"type":"Text","value":"Label"},"homepage_card.rotating_cards":{"type":"Group","value":[{}]}}

where the keys have a dot.

It did not seem to work for this case when I was trying to sort homepage_card.sequence.value

I needed to sort a list by string ex: all items with the property "source"
if it equals to "Unlinked" it should drop to the end of the list
if it doesn't equals to "Unlinked" it should be shifted to start of the array
I managed to do this like this:

  return sortArray(list, {
    by: "source",
    order,
    computed: {
      total: source => (source === "Unlinked" ? 1 : 0),
    },
  });  

I suggest you add a support for that

Update customOrders to also accept a standard sort compare function.

E.g.

sortArray(partsOfTheDay, {
  order: 'time',
  customOrders: {
    time: (a, b) => return a > b ? 1 : -1 // etc
  }
})

For example.

const records = [
  { a: 4, b: 1, c: 1 },
  { a: 4, b: 3, c: 1 },
  { a: 2, b: 2, c: 3 },
  { a: 2, b: 2, c: 2 },
  { a: 1, b: 3, c: 4 }
]
sort(records, [
  [ 'a', 'desc' ],
  [ 'b', 'asc' ],
  [ 'c', 'desc' ]
])

Just found out about this library, great job!
reading the code, the sort happens in-place. It would be nice if I could leave the original array as is, and get a new sorted array

Sorting of this failed:

   var ar = [[99, "a"], [1, "a"]];
   sortArray(ar, {by:[1,0]});

I changed this line
if (result === 0 && by[byIndex + 1]) {
to this
if (result === 0 && (undefined !== by[byIndex + 1])) {
to fix it.

I'm using sortArray with an array that contains null values in field.

sortArray(myArray, {by: ['fieldA',fieldB']})

fieldA contains two values, null and the number "1". Regardless of how I sort the array (asc or desc), the null values are always at the end. I was expecting them to be first when using asc order but they are last in both cases.

For example

const fixture = [
  { a: 5, b: 10 },
  { a: 2, b: 10 },
  { a: 3, b: 10 },
  { a: 1, b: 10 },
  { a: 4, b: 10 }
]
const by = [
  item => item.a + item.b
]
/* Sorts recordset by the result of `a + b` for each object in the array */
const result = sort(fixture, by)

Hi -- is there any way to control whether the sorting for a property is in ascending or descending order?

Need a options.NaNrank option - same functionality as options.undefinedRank and options.nullRank but for NaN values.
