local aggregate = import "github.com/jsonnet-libs/xtd/aggregate.libsonnet"

aggregate implements helper functions to aggregate arrays of objects into objects with arrays.

Example:

local apps = [
  {
    appid: 'id1',
    name: 'yo',
    id: i,
  }
  for i in std.range(0, 10)
];

aggregate.byKeys(apps, ['appid', 'name']);

Output:

{
   "id1": {
      "yo": [
         {
            "appid": "id1",
            "id": 0,
            "name": "yo"
         },
         {
            "appid": "id1",
            "id": 1,
            "name": "yo"
         },
         ...
      ]
   }
}
